Ace Combat 7 Mission 11 Fleet Destruction is a 15-minute strike against the Njord Fleet and two offshore platforms. The goal isn’t to wipe every enemy marker off the map. You need to earn enough points for your chosen difficulty, and destroying the right targets can take several others down at once.
If you’ve been flying around a platform shooting one AA gun after another and running out of time, the targets underneath it are what you’re missing. There is a much quicker way to earn points: sink the main bodies of enemy ships, break the platforms’ support cores, and use the return line when your ammunition runs low.

Best aircraft and weapons for Mission 11
For Ace Combat 7 Mission 11 Fleet Destruction, a jet equipped with LASMs (Long-Range Air-to-Ship Missiles) is a sensible pick. They are designed to hit ships from far away, so you can attack without lingering among the fleet’s anti-aircraft defenses. LACMs (Land Attack Cruise Missiles) also work well against surface targets, particularly when their higher flight path gives you an unobstructed shot.
LASMs travel low, which makes your position and line of sight important. Don’t fire into a wall, the side of a dry dock or the back of a mountain and expect the missile to find a way around. Ships and platforms also carry CIWS defenses capable of shooting missiles out of the air. Change your angle or overwhelm the defenses instead of repeating a failed single-shot attack.
You don’t need to own the game’s most expensive aircraft. A controllable multirole jet with good surface weapons and enough standard missiles to deal with aircraft is a better starting point than an unfamiliar superplane.
Ace Combat 7 Mission 11 Fleet Destruction walkthrough: which targets to hit first
1. Destroy the main fleet to the east
For the simplest first clear, fly east and begin with the warships. Aim at the ship’s hull target, not each separate gun, SAM or VLS mount. When the ship sinks, its remaining components are destroyed too, making the attack far more valuable. The aircraft carrier is a strong early priority because it launches fighters while it remains afloat.
Stay outside the thickest anti-aircraft fire as you line up your first strikes. If a ship is sitting in a dry dock, attack from above or its exposed end. The surrounding walls can stop missiles fired directly from the side.
2. Collapse the northern sea platform
After the fleet, head to the northern platform. It has aircraft, SAMs, AA guns and CIWS installations, but individually destroying those defenses is slow. Instead, find the targets labelled CORE underneath the platform. Blowing up a core collapses its supported section, also destroying the weapons and other targets sitting on it.
Work through the core sections rather than endlessly circling the deck. Be careful at low altitude: the gaps between the supports are tight. You can use missiles to hit the exposed cores without making a dangerous flight through every opening.

3. Resupply before you run dry
One of the most useful features in Ace Combat 7 Mission 11 Fleet Destruction is the return line. Flying across it lets you repair your plane, restock ammunition and flares, and change your special weapon. The main combat timer pauses while you are at the resupply base, although the landing procedure has its own countdown.
So if your LASMs are gone and the remaining ships are still covered in defenses, go back and rearm. It is a much better decision than spending several minutes on desperate gun runs. Check your current score when you rejoin the battle.
4. Finish at the western platform if needed
The western platform lies near the mountains, making it trickier to approach than the northern one. Its support cores are still the quickest way to destroy large groups of targets. If the fleet and northern platform haven’t already earned enough points, head west and attack the cores from a clear angle.
Enemy reinforcements arrive during the sortie, so you can also finish by targeting additional ships or aircraft. You don’t have to eliminate all three enemy groups. Reach the relevant score threshold and survive.
How to spawn CHASSEUR and IBIS in Ace Combat 7 Mission 11 Fleet Destruction
There are two optional named aces in Ace Combat 7 Mission 11 Fleet Destruction. You must first have completed this mission at least once and be playing on Normal difficulty or higher for them to appear. On your first campaign playthrough, don’t waste time chasing a spawn you cannot trigger yet.
CHASSEUR: destroy the fighters before takeoff
Head straight to the northern platform as soon as the mission starts. Destroy all fighters parked there before any get airborne. CHASSEUR, flying a Rafale M, then appears to the west. Attack the flight deck quickly; if you head to the fleet first, you risk missing the window for this ace.
IBIS: fly through a platform gap
For IBIS, fly through the narrow space around the support cores underneath either the northern or western sea platform. The Su-33 ace usually appears near the eastern fleet while its aircraft carrier is still intact. If that carrier has already been destroyed, IBIS can spawn near the other platform instead. In either case it tries to escape north, so intercept it quickly.
To trigger both aces in one attempt, change the usual route: tackle the northern platform first, eliminate its grounded fighters, then pass through the gap for IBIS. Only after that should you focus on the fleet and the remaining score.
Ace Combat 7 Mission 11 Fleet Destruction: questions and common mistakes
Do I need to destroy every ship in Ace Combat 7 Mission 11 Fleet Destruction?
No. The mission checks your score against the difficulty requirement, not whether every ship and platform has been wiped out. Taking out the fleet and a major platform can be enough; use remaining targets to close any gap.
Why do my missiles disappear before hitting the fleet?
Naval CIWS defenses can intercept them. If an attack keeps failing, switch approach direction, deal with the defensive installation or send missiles in rapid succession. Trying the same isolated shot repeatedly just wastes ammunition.
Can I resupply during Ace Combat 7 Mission 11 Fleet Destruction?
Yes. Use the return line to replenish weapons and repair your jet. The main mission clock pauses while you’re resupplying, but you must still complete the separate landing sequence in time.
Where are the platform cores in Ace Combat 7 Mission 11 Fleet Destruction?
Look underneath the deck and supporting sections of each sea platform, not on top beside the AA guns. Line up with a support and get low enough to see the CORE target. A successful hit can collapse an entire section, including targets above it. If your missiles keep hitting the deck, change altitude and approach the support from the side.
How do I reach 30,000 points in Ace Combat 7 Mission 11 Fleet Destruction?
On Ace difficulty, 30,000 points is the minimum completion target. Clear the fleet’s main ship hulls, collapse the northern platform’s cores, and move on to the western platform or reinforcements if your score is short. The same route works at lower difficulties, which have smaller targets.
Is the completion score also the S-rank score?
No. The table above gives the points required to pass. An S rank is a more demanding result, so aim to destroy as many high-value targets as efficiently as possible. Platform collapses and ship-hull kills are the best way to avoid wasting your limited battle time.
The bottom line for Ace Combat 7 Mission 11 Fleet Destruction is simple: target hulls, target cores, and don’t be afraid to rearm. That will get you further than chasing every red icon on the screen.
