Earn S-Rank on all 30 missions in Ace Combat 8: Wings of Theve on Ace difficulty. Discover mission-by-mission strategies, recommended aircraft and weapons, scoring tips, boss tactics, and the requirements for unlocking the Ace of Aces trophy.
Finishing Ace Combat 8: Wings of Theve is one thing. Earning an S-Rank on every mission at the highest difficulty is an entirely different challenge.
You can shoot down dozens of enemies, survive a difficult battle, and still finish with an A-Rank because you spent too long chasing unnecessary targets.
Other missions are even trickier. You might need to protect vulnerable allies, navigate without weapons, intercept incoming missiles, or destroy specific components of a massive enemy superweapon.
Getting an S-Rank isn't about destroying everything. It's about earning enough points while completing the mission efficiently.
Ace Combat 8 features 30 numbered campaign missions, each with different objectives and scoring considerations.
To earn the Ace of Aces trophy or achievement, you must complete all 30 numbered missions with an S-Rank on Ace difficulty.
Fortunately, you don't need to earn every S-Rank during one uninterrupted campaign playthrough.
Free Mission mode allows you to replay individual missions using aircraft and upgrades you've already unlocked.
This guide covers:
How Ace difficulty and S-Rank scoring work.
The best aircraft and weapons for different mission types.
Practical S-Rank strategies for all 30 missions.
Important enemy threats, boss mechanics, and objective changes.
Common mistakes that cost time or valuable score.
How to fix missions where you keep earning A-Rank.
Spoiler warning: This guide discusses late-game missions, major enemy encounters, and campaign objectives.
Before attempting your first Ace difficulty S-Rank, you need to understand why a successful mission doesn't always receive the highest grade.
Ace Combat 8 evaluates several aspects of your performance.
The relative importance of these factors varies between missions.
Finishing objectives quickly is one of the most important factors.
A clean mission with efficient target selection can outperform a run where you destroy additional enemies but waste time traveling across the map.
However, speed alone isn't always enough.
Some missions require substantial destruction scores, meaning completing the objective immediately can leave you short of the S-Rank requirement.
The goal is to build enough score without unnecessarily extending the mission.
Destroying enemy units contributes to your score.
Different targets have different point values.
High-value aircraft, important surface installations, and valuable targets can provide more efficient scoring opportunities than isolated low-value enemies.
The best approach is usually to destroy targets that offer a strong score reward without requiring long detours.
Current post-launch S-Rank guides report a 5,000-point bonus for completing a mission without taking damage.
This can be extremely valuable during close scoring attempts.
However, taking damage does not automatically prevent an S-Rank.
If you lose the bonus, you may still achieve the required result through efficient combat and mission completion.
Avoid unnecessary damage, but don't sacrifice an entire mission objective just to preserve a perfect aircraft.
Special enemy pilots can appear when you satisfy certain mission conditions.
These named Aces provide additional points when destroyed.
Post-launch guides report that an enemy Ace can be worth approximately 2,000 points.
However, attempting to spawn one isn't always worth the risk.
Some require dangerous detours or unusually difficult conditions.
If pursuing an Ace threatens your mission completion or consumes too much time, skip it and focus on your S-Rank.
Ace Combat 8 doesn't use one universal S-Rank score requirement across all missions.
A high-scoring destruction mission and a scripted escort mission need different approaches.
Some sorties reward sustained target destruction.
Others depend heavily on completing unusual objectives efficiently.
Exact numerical S-Rank thresholds for every mission are not consistently documented in reliable post-launch references.
For that reason, this guide focuses on practical, verified mission strategies rather than presenting speculative score requirements or guaranteed completion times.
Ace difficulty is the highest difficulty setting in Ace Combat 8.
It isn't immediately available when starting the game.
Complete the main campaign on Elite difficulty.
Doing so unlocks Ace difficulty for subsequent campaign runs and individual mission replays.
Higher difficulty makes enemy encounters more dangerous, so surviving requires better positioning and more careful decisions.
Free Mission unlocks after completing the campaign.
It allows you to replay individual missions using aircraft, special weapons, and upgrade parts you have already obtained.
Free Mission is especially useful for S-Rank attempts because it removes most campaign aircraft restrictions.
Some story missions normally limit you to carrier-capable aircraft or require you to continue using the same aircraft across connected sorties.
Free Mission generally removes these restrictions.
The main exception is Mission 14, where you must fly the unarmed A-6E Intruder.
No.
You can earn an S-Rank on one mission, replay another later, and return to difficult missions whenever you want.
Each qualifying Ace difficulty S-Rank counts toward the Ace of Aces achievement.
You don't need to restart the entire campaign because of one A-Rank.
The Prologue is also separate from the 30 numbered missions required for this challenge.
There isn't one aircraft that performs best in every mission.
However, some advanced aircraft are particularly effective for S-Rank attempts.
The X-40 Nightmare is a powerful endgame aircraft.
Its UAVT special weapon can engage both air and ground targets, making it valuable across many missions.
However, UAVT ammunition is limited, and its precision may be less efficient against large clusters of surface targets.
The X-40 is a strong general-purpose option, not a universal solution.
The FA-36 Game is an excellent advanced aircraft for challenging campaign replays.
Its varied special weapons make it useful for different mission types.
The SOD weapon is particularly attractive when dealing with dense ground-target formations.
Use the FA-36 when you need to destroy concentrated groups of surface enemies quickly.
These advanced fighters are excellent choices for missions dominated by enemy aircraft.
Their maneuverability and fighter-oriented weapon options make them suitable for interception, dogfighting, and battles against dangerous pilots.
Weapons such as QAAM and other specialized air-to-air missiles can be valuable when dealing with agile opponents.
The F-35C is an attractive option for missions combining aerial and surface targets.
Its multirole capabilities allow you to select equipment based on the mission's requirements.
This flexibility is particularly useful when objectives change during a sortie.
Before selecting your aircraft, identify the main threat.
Large enemy aircraft formations: Consider 4AAM, 6AAM, or suitable high-capacity air-to-air weapons. These can help eliminate groups efficiently when you have favorable attack angles.
Dangerous individual fighters: Consider weapons such as QAAM or HCAA, depending on your available aircraft. Focus on accurate launches rather than wasting ammunition during poor attack opportunities.
Dense ground targets: Consider SOD, bombs, or multi-target air-to-ground weapons. Area attacks can eliminate several enemies during one well-positioned strike.
Naval targets: Use appropriate anti-ship or heavy surface-attack equipment. Avoid spending your entire sortie repeatedly attacking ships with an inefficient loadout.
Mixed objectives: A multirole aircraft can provide flexibility, but you still need to understand which targets will be most important.
For S-Ranks, weapon efficiency often matters more than aircraft popularity.
The opening missions test basic combat skills, interception, escorting, and surface attacks.
Although they're easier than later operations, poor target selection can still ruin an S-Rank attempt.
Operation: Seabird
Recommended Loadout: Fast fighter with reliable air-to-air weapons.
The mission starts with UAV engagements before introducing enemy fighters protecting an AWACS aircraft.
Your main scoring opportunity comes from handling the fighter formation before finishing the final objective.
S-Rank Strategy:
Destroy the opening UAVs efficiently without wasting time on unnecessary maneuvers.
When the MiG-21bis fighters appear, eliminate them before destroying the AWACS.
Destroying the fighter formation triggers the enemy Ace, Gigas.
Shoot down Gigas for additional points if you can do so without a significant delay.
Finish the AWACS to complete the mission.
Common Mistake: Destroying the AWACS immediately and ending the mission before collecting valuable fighter and Ace points.
Operation: Falling Sparks
Recommended Loadout: Fighter with multi-target air-to-air weapons.
Your objective is to defend the carrier Endurance against successive waves of enemy bombers.
The biggest threat isn't necessarily the closest enemy aircraft.
It's the bomber currently approaching the carrier.
S-Rank Strategy:
Intercept the opening A-6E attackers quickly.
Prioritize bomber formations over fighters attempting to lure you away.
Destroying four enemies during the opening three minutes can trigger Crematio, the mission's named Ace.
Consider intercepting Crematio while moving between bomber waves if it doesn't endanger the carrier.
Focus on the later Tu-95 formations before dealing with their escorts.
Common Mistake: Spending too much time dogfighting escort fighters while bombers continue their attack runs.
Operation: Frostwave
Recommended Loadout: Fast air-superiority fighter.
This is a defensive mission involving several incoming enemy formations.
Efficient interception is more important than remaining in one area and reacting after every wave appears.
S-Rank Strategy:
Destroy the opening Mi-24 helicopter formation.
Move toward the northeast to intercept approaching fighters and bombers.
Avoid repeatedly returning to the center of the map when additional formations approach from similar directions.
Intercept the Tu-160 bombers before they reach White Valley Base.
Destroy the remaining dangerous aircraft before completing the mission.
The enemy Ace, Raia, can appear if you satisfy the relevant bomber interception condition.
Common Mistake: Chasing minor enemies while incoming bombers approach the defended facilities.
Operation: Elder Hand
Recommended Loadout: Multirole aircraft with strong anti-surface weapons.
This mission involves attacking enemy fleets and surface defenses around Newfield Island.
You have opportunities to earn points from multiple groups of targets.
S-Rank Strategy:
Begin with the western airfield and nearby defenses.
Destroy convenient enemy aircraft before they can become airborne.
Eliminate SAM positions, anti-aircraft weapons, and nearby ships.
Continue toward the eastern fleet while attacking worthwhile targets along your route.
Build a useful destruction score before eliminating the final mission targets.
The enemy Ace, Auster, requires flying through a dangerous tunnel.
Our recommendation: Save that risky maneuver for a separate Assault Record attempt if it interferes with your S-Rank.
Common Mistake: Risking a strong sortie on a difficult optional tunnel maneuver.
Operation: Long Shot
Recommended Loadout: Multirole aircraft with effective air-to-air and surface weapons.
Mission 5 revolves around supporting landing craft during a major assault.
These friendly units can take heavy damage if enemy forces are allowed to attack them.
S-Rank Strategy:
Stay close enough to the LCACs to intercept immediate threats.
Destroy helicopters and aircraft approaching the formation.
Remove artillery and ground defenses attacking the landing craft.
Use Joker Flight commands to help distribute pressure across enemy groups.
When the operation changes to withdrawal, protect the retreating forces instead of continuing the original assault.
Keeping all eight LCACs alive can trigger the enemy Ace, but achieving that condition on Ace difficulty is especially demanding.
Don't sacrifice a reliable S-Rank route chasing an optional Ace.
Common Mistake: Flying too far from the landing craft to pursue secondary targets.
Operation: Redouble
Recommended Loadout: Versatile multirole aircraft.
Your main responsibility is protecting two helicopter assault groups.
Spread 1 and Spread 2 operate on different approaches, so remaining in one location throughout the operation is ineffective.
S-Rank Strategy:
Identify threats closest to both helicopter formations.
Destroy dangerous surface defenses and enemy aircraft along their routes.
Switch between the two groups when radio communications indicate a new threat.
Intercept the escaping enemy transport when it becomes an objective.
Support the ground assault after the helicopters land.
Be careful around the protected fuel and ammunition facilities.
Destroying important friendly objectives can ruin the mission.
Common Mistake: Clearing one side of the battlefield while ignoring the other assault group.
Operation: Squeeze
Recommended Loadout: FA-36 with SOD or another strong area-attack setup.
This is a target-rich ground destruction mission.
Large groups of facilities and defenses provide excellent opportunities to build your score.
S-Rank Strategy:
Attack dense clusters of ground targets rather than isolated enemies.
Use area weapons against installations positioned close together.
Take advantage of explosive environmental objects when they can destroy additional targets.
Avoid excessive travel between distant low-value targets.
Once you've built sufficient score, focus on efficient mission completion.
The mission includes multiple sectors, such as the solar installation, airfield, ammunition storage, and refineries.
A return line is available if you need additional ammunition.
Common Mistake: Spending too much time attacking scattered targets when nearby clusters provide better scoring opportunities.
Operation: Gut Shot
Recommended Loadout: Multirole aircraft with strong surface-attack capabilities.
This mission combines defending friendly forces, destroying artillery, and intercepting incoming aircraft.
Your priorities change throughout the battle.
S-Rank Strategy:
Eliminate surface defenses that threaten friendly forces.
Destroy artillery and armored units preventing allied movement.
Use environmental explosions when they offer efficient target destruction.
Immediately intercept incoming Tu-160 bombers when they appear.
Finish dangerous Shadow Squadron aircraft without allowing them to disrupt your defense.
The named Ace, Tesera, has a special condition involving destroying non-target surface weapons.
That additional objective may increase your score, but it can also extend the mission.
Common Mistake: Continuing a ground-attack run after dangerous bomber formations appear.
Operation: Ogre Pitfall
Recommended Loadout: Heavy anti-surface aircraft.
This mission features one of the game's major Land Battleship encounters.
Simply firing at the main hull isn't enough.
You need to complete several connected objectives.
S-Rank Strategy:
Destroy dangerous escort defenses and active weapons.
Protect the allied explosive trucks as they approach the battleship.
Shoot down quadcopter UAVs threatening those trucks.
Attack exposed track components after the explosive charges create openings.
Follow later mission instructions to destroy the required buildings and final propulsion targets.
The battle involves multiple phases, so preserve enough ammunition for the later objectives.
Common Mistake: Focusing on the battleship itself while the support trucks are destroyed by defensive UAVs.
Operation: Raincoat
Recommended Loadout: Fast fighter with effective interception weapons.
The mission involves protecting allied naval forces while enemy airships direct powerful attacks through cloud cover.
These airships can be difficult to locate because of electronic interference and limited visibility.
S-Rank Strategy:
Defend the fleet against immediate aerial threats.
Watch for laser designators revealing incoming attacks.
Follow the laser guidance back toward the responsible airship.
Destroy the airship quickly instead of spending time fighting unrelated aircraft.
When multiple guidance sources appear, eliminate the active threats before returning to normal air combat.
A fast destruction of the relevant airship can also trigger the enemy Ace, Vorago.
Common Mistake: Searching the clouds randomly while an active guidance system prepares another attack.
The middle missions introduce more complicated objectives.
You'll encounter large transport aircraft, unusual escape sequences, disguised enemy vessels, and powerful surface targets.
Efficiently recognizing objective changes becomes increasingly important.
Operation: Gaffed Card
Recommended Loadout: Fighter or multirole aircraft with accurate air-to-air weapons.
This mission involves intercepting enormous Podarge transport aircraft carrying important military equipment.
Electronic interference and poor visibility complicate the search.
S-Rank Strategy:
Follow visible contrails to locate the transport groups.
Remove defensive weapons when they prevent effective attacks.
Concentrate fire on the aircraft's exposed propulsion components.
Destroy nearby valuable enemy fighters when they are convenient targets.
Finish available scoring opportunities before destroying the final transport.
The large transports have multiple destructible components.
Attacking the correct parts efficiently is more useful than spreading damage across several aircraft without finishing any of them.
Common Mistake: Damaging numerous transports without destroying them, allowing the mission to become unnecessarily long.
Operation: Worker Bee
Recommended Loadout: Fast air-to-air fighter.
The mission focuses on defending Fort Grays against successive enemy attacks.
The most important objective changes when enemy aircraft begin deploying cruise missiles.
S-Rank Strategy:
Intercept incoming enemy aircraft threatening the base.
Destroy valuable targets during moments when the defense is stable.
Watch for C-130 aircraft carrying missile pallets.
Destroy the missile pallets or intercept launched cruise missiles before they reach the base.
Return toward Fort Grays after each engagement instead of chasing distant enemies.
Missiles already approaching the base take priority over ordinary fighters.
Common Mistake: Remaining committed to a dogfight while incoming cruise missiles threaten the defended installation.
Operation: Twin Birds
Recommended Loadout: Flexible fighter with reliable air-to-air weapons.
This mission involves protecting an allied transport through hostile territory.
The objective requires balancing forward attacks with staying close enough to respond to new threats.
S-Rank Strategy:
Stay within supporting distance of the transport.
Fly ahead when necessary to remove SAM sites and anti-aircraft positions.
Watch for portable missile launchers appearing along the route.
Return toward the transport whenever a new immediate threat emerges.
Clear the landing zone before the aircraft reaches its destination.
Destroying certain radar towers can trigger the enemy Ace, Sicarius.
However, don't pursue optional targets if doing so leaves the transport exposed.
Common Mistake: Flying too far ahead and failing to respond when hidden ground defenses activate.
Operation: Homing Pigeon
Aircraft: Fixed unarmed A-6E Intruder.
Mission 14 is unlike normal Ace Combat gameplay.
You cannot select an advanced fighter or rely on special weapons.
Your objective is escaping enemy territory without conventional combat.
S-Rank Strategy:
Complete the initial takeoff carefully and avoid unnecessary corrections.
Fly through the canyon while using terrain to reduce radar exposure.
Avoid climbing into open areas where enemy sensors can detect your aircraft.
Maintain enough speed to navigate the escape route safely.
Use available concealment when enemy aircraft and missiles threaten your escape.
The mission also has a separate medal condition involving avoiding radar detection.
Important: You don't need to treat this mission as an ordinary destruction-score challenge.
Navigation, survival, and efficient objective completion are the priorities.
Common Mistake: Attempting to fight enemy aircraft or taking dangerous shortcuts through exposed airspace.
Operation: Deal Cards
Recommended Loadout: High-damage air-to-air weapons.
This is another demanding fleet-defense mission.
Large enemy bombers pose a greater immediate threat than most escort fighters.
S-Rank Strategy:
Position yourself between incoming bomber formations and the friendly fleet.
Prioritize heavy bombers before unrelated fighters.
Attack vulnerable aircraft components when they become available.
Break away after each firing pass rather than remaining exposed behind enemy bombers.
Intercept anti-ship missiles and other direct threats whenever necessary.
Save enough ammunition for the later formations.
Common Mistake: Wasting your strongest weapons on minor enemies while dangerous bombers approach the fleet.
Operation: Lighthouse Lady
Recommended Loadout: Fast multirole aircraft with accurate missiles.
This mission requires identifying enemy vessels hidden among civilian shipping traffic.
Randomly attacking ships is not a solution.
S-Rank Strategy:
Search for the three disguised enemy container ships.
Use their distinctive deck crane arrangement and sun markings to identify them.
Destroy confirmed enemy vessels quickly.
Avoid wasting time or ammunition on civilian ships.
If explosive UAVs launch, prioritize destroying them before they complete their dangerous ascent.
Learning the ship-identification patterns is the biggest improvement you can make.
Once you recognize the correct targets quickly, the mission becomes significantly more manageable.
Common Mistake: Spending too long searching without recognizing when the mission's priority changes to UAV interception.
Operation: Broncobuster
Recommended Loadout: Heavy anti-surface weapons.
Another Land Battleship encounter, but this mission places additional emphasis on supporting friendly aircraft.
Your allies need a safe route before their attacks can succeed.
S-Rank Strategy:
Destroy SAM installations and air-defense positions threatening friendly bombers.
Keep the bomber approach route clear.
Avoid unnecessary direct attacks against heavily protected battleship sections.
Use Joker Flight commands to help engage available targets.
Attack newly exposed components as the mission progresses.
Mission 17 also contains a unique medal associated with using Joker Flight to destroy the primary targets.
That medal condition is separate from your S-Rank objective.
Common Mistake: Attacking the battleship before removing the defenses preventing the allied strike.
Operation: Branching Path
Recommended Loadout: Fast fighter with reliable missiles.
The most important mechanic involves intercepting rockets after launch.
Destroying them at the wrong stage is not the intended objective.
S-Rank Strategy:
Follow the initial mission instructions through the Rainband.
Respond to threats involving Queen Flight.
Return toward the launch objective when ordered.
Allow the rockets to reach the required launch phase.
Destroy the launched rockets before they climb beyond the mission's interception limit.
React to dangerous falling debris afterward.
This mission is about recognizing scripted objectives.
Common Mistake: Attempting to destroy the rockets before they become the required airborne targets.
Operation: Silver String
Recommended Loadout: Multirole aircraft with accurate surface weapons.
This mission involves a powerful Land Battleship positioned near the Space Elevator.
The surrounding environment introduces additional restrictions.
S-Rank Strategy:
Eliminate air defenses preventing allied aircraft from reaching their objectives.
Allow the mission's planned attacks to open the next phase.
Target enemy weapon systems and exposed components as they become available.
Avoid unnecessary attacks toward protected structures.
Complete each newly revealed objective without returning to already-cleared areas.
Precision matters more than uncontrolled firepower.
Common Mistake: Repeatedly attacking protected hull sections or ignoring collateral-damage restrictions.
Operation: Migration Keeper
Recommended Loadout: Fast interception fighter.
Mission 20 involves protecting a transport during an aerial escort operation.
Enemy fighters are dangerous, but the most important threat is a specialized missile.
S-Rank Strategy:
Stay within supporting distance of the escorted aircraft.
Destroy approaching enemies that directly threaten its flight path.
Immediately respond when the large incoming missile becomes an objective.
Destroy that missile directly instead of relying on defensive countermeasures.
Resume attacking valuable enemy aircraft when the immediate escort threat is gone.
The missile uses image recognition, so ordinary chaff and flares aren't sufficient to make it abandon the escorted transport.
Common Mistake: Remaining in a distant dogfight while the specialized missile approaches its target.
The final ten missions contain some of the most demanding challenges.
Expect extended combat, difficult escort operations, large-scale battles, and encounters with powerful enemy weapons.
Preparation and objective awareness are especially important.
Operation: Dawn Rising
Recommended Loadout: Multirole aircraft with strong interception capability.
Your main responsibility is protecting important launch facilities and the shuttle.
Enemy aircraft and surface forces threaten multiple parts of the operation.
S-Rank Strategy:
Prioritize enemies moving toward the shuttle and control facilities.
Destroy nearby high-value targets when the defended assets are safe.
Use available electronic support when stronger enemy formations arrive.
Preserve enough special ammunition for later attacks.
Consider resupplying at the eastern air base when doing so won't leave the objective exposed.
Keeping the escort objective undamaged is also associated with a separate mission medal.
Common Mistake: Leaving the protected facilities vulnerable while pursuing enemies far from the launch complex.
Operation: Patch of Blue
Recommended Loadout: Fast aircraft with effective long-range weapons.
This mission involves intercepting a large target before it reaches dangerous enemy defenses.
The longer the pursuit continues, the more complicated the engagement becomes.
S-Rank Strategy:
Close the distance quickly without wasting time on unrelated enemies.
Target available propulsion components when they become vulnerable.
Maintain movement to avoid defensive fire.
Avoid repeated head-on or poorly positioned attacks that force long recovery maneuvers.
Withdraw when the mission objective changes.
This mission rewards efficient pursuit and accurate attacks.
Common Mistake: Allowing the target to reach heavily defended airspace because you spent too long chasing secondary enemies.
Operation: Rumbling
Recommended Loadout: Heavy surface-attack aircraft.
Expo City contains numerous dangerous ground targets.
Land ships, artillery, and powerful defensive systems can prevent allied forces from advancing.
S-Rank Strategy:
Attack dangerous surface weapons holding up allied ground units.
Prioritize groups of targets that can be destroyed efficiently with area weapons.
Follow the allied advance rather than clearing unrelated sections of the city.
Respond to naval bombardment when it becomes a threat.
Use the available return line if you genuinely need ammunition for another major engagement.
This mission provides numerous scoring opportunities, but poor routing can waste a significant amount of time.
Common Mistake: Clearing the map systematically instead of following the actual mission objectives.
Operation: Coastal Hammer
Recommended Loadout: Multirole or attacker aircraft with area weapons.
The mission involves supporting several assault groups landing at separate locations.
Different friendly forces face different threats.
S-Rank Strategy:
Destroy coastal defenses attacking the landing forces.
Watch the status of Alpha, Bravo, and Charlie.
Move toward whichever group faces the most immediate danger.
After the initial landing, support the advance inland.
Preserve enough surface-attack capability for later defenses near the geothermal facilities.
Don't spend your entire weapon supply on opening naval targets.
Common Mistake: Remaining with one assault group after another group begins taking heavy damage.
Operation: Paint it Blue
Recommended Loadout: Heavy multirole aircraft.
This operation continues the Rocky Island assault with a demanding ground battle.
The battlefield is divided between multiple allied routes.
S-Rank Strategy:
Support whichever friendly advance is currently blocked.
Eliminate dangerous armored vehicles and surface defenses.
Use your machine gun on suitable lighter targets when accurate attacks are possible.
Preserve heavier weapons for powerful land ships and important installations.
Return to the main objective once the allied forces begin advancing again.
A return line is available for resupply when needed.
Common Mistake: Remaining on one side of the battlefield while the other assault group becomes stalled.
Operation: King Tide
Recommended Loadout: Multirole aircraft with strong anti-ship capability.
Mission 26 combines naval combat with demanding aerial threats.
The battlefield can become crowded, making target selection particularly important.
S-Rank Strategy:
Prioritize bombers and anti-ship threats attacking friendly vessels.
Destroy important surface defenses when they block allied operations.
Use appropriate anti-ship weapons against valuable naval targets.
Listen to fleet communications to identify the next dangerous sector.
Resupply when necessary before another major surface battle.
The mission demands constant reassessment.
Common Mistake: Focusing entirely on enemy ships while incoming aircraft attack the friendly fleet.
Operation: Rootbreaker
Recommended Loadout: Heavy surface-attack aircraft with area weapons.
Fatsia is a massive enemy Mega Float with multiple destructible sections.
The battle rewards understanding environmental destruction and responding quickly to changing objectives.
S-Rank Strategy:
Attack exposed structural supports and important exterior targets.
Use chain reactions to damage multiple connected sections efficiently.
Avoid spending excessive ammunition on targets that aren't necessary for progression.
Stop firing when the operation issues its cease-fire instruction.
Follow the new objective toward the central structure.
Attack the exposed reactor when the mission makes it vulnerable.
Post-launch mission guides report that the reactor requires two successful strikes before the shutter closes.
Common Mistake: Continuing to destroy exterior targets after the mission has moved to the next phase.
Operation: Locust Purge
Recommended Loadout: Advanced fighter with substantial air-to-air ammunition.
This is one of the most demanding air-defense missions because of the large number of enemy formations.
You must protect Sema Island while surviving sustained aerial combat.
S-Rank Strategy:
Prioritize approaching bombers over unrelated fighter engagements.
Use multi-target air-to-air weapons against suitable enemy formations.
Avoid chasing retreating aircraft far from the defended island.
Resupply at the Cima Island airstrip when the mission allows it and the immediate situation is stable.
Preserve enough ammunition for the later enemy waves.
The mission also includes an important air-superiority phase involving additional mercenary support.
Rapidly destroying available enemy aircraft can help stabilize the battle.
Common Mistake: Exhausting all your missiles before the later formations arrive.
Operation: Lunar Eclipse
Recommended Loadout: Agile fighter with accurate air-to-air weapons.
Mission 29 centers on a dangerous advanced aircraft and an important guidance threat.
The enemy's maneuverability makes careless missile launches ineffective.
S-Rank Strategy:
Maintain enough pressure on the enemy aircraft to interrupt dangerous guidance activity.
Avoid wasting missiles during poor attack angles or scripted defensive phases.
Respond to escort UAVs and protective systems when they become active.
Attack exposed objectives during the correct vulnerability windows.
Continue following the mission after the first apparent victory.
The encounter involves multiple phases, and destroying the initial target does not necessarily complete the operation.
Common Mistake: Spending ammunition on an invulnerable target or becoming so focused on dogfighting that you ignore the guidance objective.
Operation: Showdown
Recommended Loadout: Versatile multirole aircraft with suitable air-to-air and surface-attack weapons.
The final mission combines escort defense, missile interception, and a powerful submarine encounter.
Your main responsibility is protecting the Endurance while responding to several changing threats.
S-Rank Strategy:
Intercept incoming anti-ship missiles threatening the carrier.
Deal with guidance aircraft and other active threats as the mission develops.
Follow the objectives involving the Rainband and guidance systems.
Attack the submarine's exposed weapon systems when they become available.
Watch for later launch components and the final direct threat to the Endurance.
Finish the last required objective without becoming distracted by optional enemies.
The submarine begins underwater, so attempting to attack it before the proper phase wastes time.
Common Mistake: Focusing on the enemy submarine while incoming missiles or other active threats are about to strike the Endurance.
Sometimes you can complete a mission without obvious mistakes and still receive an A-Rank.
When that happens, avoid changing everything at once.
The best approach is identifying which part of your performance needs improvement.
If you're finishing quickly but earning insufficient points, you may be overlooking valuable enemies.
Consider adding:
High-value aircraft along your normal route. Destroying one valuable enemy can be more efficient than making a long detour to attack several weaker targets.
Nearby surface-target groups. Area weapons can eliminate several enemies without requiring repeated passes.
Named enemy Aces when convenient. They can provide additional points, but only when their spawn conditions don't disrupt the mission.
Important secondary defenses. SAM sites, naval defenses, and other relevant targets may provide useful score while making later attacks safer.
Don't assume that every optional enemy is worth destroying.
Focus on efficient scoring opportunities.
If your destruction score is strong but you still finish below S-Rank, improve your route.
Look for opportunities to reduce wasted movement.
Common improvements include:
Taking better attack angles instead of repeatedly overshooting.
Using special weapons to destroy groups of enemies.
Skipping isolated targets far from the objective.
Preparing for known enemy waves before they arrive.
Immediately responding to mission objective changes.
A faster route with fewer unnecessary engagements can produce a better final result.
The reported no-damage bonus can be valuable for borderline S-Rank attempts.
Consider changing how you approach dangerous targets.
Avoid flying directly into concentrated anti-aircraft defenses.
Destroy threatening weapons before beginning slower attack runs.
Use high-G turns and available countermeasures appropriately when enemy missiles threaten your aircraft.
However, don't become so defensive that you lose excessive time.
The goal is balancing survival and combat efficiency.
Checkpoint restarts can make S-Rank scoring more difficult.
Post-launch guides recommend restarting the full mission after a major early mistake rather than repeatedly relying on checkpoints.
That doesn't mean checkpoint restarts universally prevent an S-Rank.
But starting again can be the better option when your score or completion time has already fallen significantly behind a successful attempt.
A powerful jet isn't automatically suitable for every operation.
For example, an advanced air-superiority fighter may be excellent in Mission 28 but less efficient against dense ground targets in Mission 7.
Consider switching to a different aircraft or special weapon when your current loadout struggles with the main target type.
Sometimes a suitable weapon choice can improve your score more than changing your flying technique.
Ace Combat 8 also includes named enemy Aces, Assault Records, and mission-specific medals.
These provide additional challenges beyond simply completing the campaign.
However, attempting to obtain every objective in one sortie can make S-Rank runs unnecessarily difficult.
Some enemy Aces appear after straightforward conditions.
If you can trigger one through normal mission progression, shooting it down may provide additional points without much extra time.
Likewise, certain mission-specific objectives naturally align with safe and efficient play.
In those cases, working toward both objectives can be worthwhile.
Other challenges introduce substantial risks.
For example:
Mission 4: Flying through the narrow tunnel can risk a collision.
Mission 5: Keeping every landing craft alive is especially difficult on Ace.
Mission 14: The radar-avoidance medal requires particularly careful navigation.
Mission 17: The Joker Flight-specific medal introduces an unusual combat restriction.
Trying to satisfy these conditions may interfere with your best S-Rank strategy.
Our recommendation: Prioritize the S-Rank and return for optional challenges separately when they require dangerous or inefficient actions.
Because Free Mission supports replaying individual sorties, you don't need to force every objective into one successful attempt.
Several mistakes appear repeatedly during difficult S-Rank attempts.
Destroying final objectives too early.
Some missions end immediately when the last required target is destroyed. If your score is too low, completing the objective prematurely can prevent an S-Rank. Collect valuable nearby points before ending the operation when the mission allows it.
Chasing every enemy on the radar.
Not all targets are equally important. Spending too long pursuing isolated fighters can reduce your time bonus and distract you from dangerous mission threats.
Ignoring objective changes.
Many missions introduce new threats through scripted phases. When the objective changes, your target priorities should change immediately.
Using expensive aircraft without suitable weapons.
High aircraft performance doesn't replace an appropriate loadout. Surface-heavy missions often benefit from area weapons, while interception missions reward effective air-to-air equipment.
Wasting special ammunition early.
Long missions may introduce difficult enemy formations or bosses after the opening phase. Preserve enough equipment to handle those encounters.
Risking unnecessary optional challenges.
Named enemy Aces and special medals can be valuable, but a risky detour may cost more than the additional score provides.
Ignoring wingmen commands.
Joker Flight can help manage enemy pressure. Directing your squadron appropriately may reduce the time spent dealing with difficult formations.
Failing to analyze A-Rank attempts.
Repeating the same approach without changing your target route, equipment, or timing rarely solves the underlying problem.
Complete missions efficiently while earning sufficient points from enemy destruction and other scoring opportunities.
Your final rank depends on several factors, including mission time, target destruction, and mission-specific objectives.
Complete the campaign on Elite difficulty.
Ace difficulty becomes available afterward.
Yes.
The Ace of Aces trophy or achievement requires an S-Rank on all 30 numbered campaign missions at Ace difficulty.
Yes.
Free Mission allows you to replay individual missions on unlocked difficulties.
You can use aircraft and equipment you have already obtained, subject to mission-specific exceptions.
The Ace of Aces requirement covers the 30 numbered campaign missions.
The Prologue is separate from that numbered mission list.
The X-40 Nightmare is a strong general-purpose option.
However, ground-heavy missions may favor the FA-36 Game or other aircraft with effective area weapons.
Air-to-air missions may be easier with advanced fighters such as the F-22A or Su-57.
No.
Taking damage doesn't automatically disqualify an S-Rank.
However, post-launch guides report a 5,000-point bonus for completing a mission without damage.

Getting S-Rank on all 30 missions in Ace Combat 8: Wings of Theve is one of the game's most demanding campaign challenges.
But the most effective approach isn't simply flying faster or destroying more enemies.
The secret to consistent S-Ranks is understanding each mission's scoring opportunities and completing its objectives efficiently.
Use high-value targets to build your score.
Choose aircraft and special weapons that match the mission.
Protect friendly units when the objective requires it, respond immediately to new threats, and avoid wasting time chasing irrelevant enemies.
For large surface battles, powerful area weapons can improve your efficiency.
For air-defense missions, fast interception and reliable missile attacks are essential.
And during complex boss encounters, knowing when targets become vulnerable is often more important than launching as many missiles as possible.
Remember that Free Mission allows you to replay difficult sorties individually.
An A-Rank doesn't mean you need to repeat the entire campaign. It simply means there's an opportunity to improve your strategy.
