Ace Combat 7 Ten Million Relief Plan DLC mission is the third and final story DLC sortie. You’ll protect patrol aircraft, use a Magnetic Anomaly Detector to find the submerged Alicorn and then attack the giant submarine before Captain Torres can fire a nuclear shell toward Oured.
The battle changes objectives several times. You cannot sink Alicorn as soon as you first spot it. Protect the search planes, locate the submarine twice, destroy its four ballast tanks, interrupt the first rail-cannon shot and finally hit the cannon’s exposed core. Missing a deadline in any phase can end the operation.
Ace Combat 7 Ten Million Relief Plan DLC mission walkthrough: defend the patrol aircraft
Operation Fisherman begins with four Osean patrol aircraft placing sonobuoys across the search area. Enemy Rafale Ms and submarine-launched UAVs attack them. Destroy aircraft threatening the patrol planes rather than chasing unrelated fighters. If all four patrol aircraft are lost, the search fails.
1. Protect Specter Squadron until the buoys are deployed
In Ace Combat 7 Ten Million Relief Plan DLC mission, listen for calls from a patrol plane under attack and intercept the nearest enemy. You don’t need to save all four, but at least one must survive long enough for the sonar data to be gathered. Once the deployment is complete, a circular search area appears on your radar.
How to find Alicorn with the MAD detector
Your Magnetic Anomaly Detector (MAD) works inside the search area, but only at the right speed and altitude. Slow to below 800 km/h and stay below about 1,900 metres. Watch the waveform at the top of your HUD. The signal strengthens and its beeps become more frequent when you move toward the submerged submarine.
2. Follow the waveform instead of flying at full speed
For Ace Combat 7 Ten Million Relief Plan DLC mission, don’t cross the marked ring on afterburners and wonder why the detector is silent. Slow down, follow the waveform direction and move toward stronger signals. The Alicorn is beneath the surface, so your regular missile locks cannot find it during this stage.
3. Destroy six jamming buoys and find it again
After you detect Alicorn once, it launches six jammer buoys that interfere with the MAD search. Destroy all six marked targets. The patrol aircraft analyse the signals again and provide a new search circle.
You’ll have roughly one minute to find the submarine a second time, while hostile SLUAVs launch to distract you. Stay at the MAD’s operating speed and altitude, follow the fresh signal and ignore unnecessary dogfights. When you locate it again, allied anti-submarine missiles force Alicorn to surface.
Ace Combat 7 Ten Million Relief Plan DLC mission Alicorn boss fight: four ballast tanks
Once the submarine surfaces, your required targets are its four BALLAST TANK sections. Destroying all four prevents it from diving and leads to the emergency cannon phase. You can also destroy its defensive guns, missile launchers and other exposed weapons to make the later stages safer.
4. Avoid railguns, barrier drones and the jammer
In Ace Combat 7 Ten Million Relief Plan DLC mission, Alicorn repeatedly surfaces, fires dangerous railgun rounds and launches barrier drones that block missiles. Stay moving when railgun fire begins. Barrier drones are easier to destroy before their defensive spheres activate, so attack them promptly or use a clearer approach angle.
The submarine can activate an electronic jammer that slows missile locks. Destroy that target when it appears, particularly if the final precision attacks are giving you trouble. Don’t keep firing at ballast tanks through an active barrier and wasting every shot.
Stop the first rail-cannon shot
After the ballast tanks are destroyed, the game switches to a very short timed objective. Hit the marked RAIL CANNON before Torres fires. The usable firing window is only around 15 seconds; one clean missile hit is enough to interrupt the shot.
For Ace Combat 7 Ten Million Relief Plan DLC mission, the trick is getting past the nearby barrier drones quickly. Turn into a clear approach rather than firing into their shields, and land a missile on the marked cannon before the countdown ends.
Destroy the cannon core within two minutes
Stopping the first shot does not complete the mission. The next update gives you two minutes to destroy the vulnerable CORE at the base of the main rail cannon. The Alicorn continues defending itself and gradually tilts backward as water floods its stern.
5. Attack from the bow or sides, not from behind
The final core is difficult to hit from above or behind because the submarine’s body obstructs the approach. Move toward the front or side, aim at the marked CORE and fire when you have a clear line. Adjust your angle as the submarine tips backward.
In Ace Combat 7 Ten Million Relief Plan DLC mission, don’t confuse the core with the long barrel you attacked moments earlier. The base of the gun is the actual final target. Destroying it prevents the second shot and sinks the Alicorn.
Best aircraft and weapons for Ten Million Relief Plan
A responsive multirole aircraft makes the changes between phases easier. You need speed and missiles to protect patrol aircraft, slow and controlled movement for the MAD search, and precise attacks against the surfaced submarine. An anti-ship weapon helps with the boss, but standard missiles are also valuable against jammer buoys and exposed components.
Ace Combat 7 Ten Million Relief Plan DLC mission FAQ
Why isn’t the MAD working?
Check your speed and height. Stay under 800 km/h and around 1,900 metres, inside the current search circle. Follow the waveform once it reacts. The search area moves after the six jammer buoys are destroyed.
How many ballast tanks must I destroy?
Four. All four are mission targets. The cannon stages begin after they have been destroyed.
Why does the final core take no damage?
For Ace Combat 7 Ten Million Relief Plan DLC mission, reposition toward the submarine’s front or side. Attacks from above or directly behind often hit the surrounding hull instead. Watch the changing tilt as Alicorn floods.
For the preceding sortie, read our Ace Combat 7 Anchorhead Raid DLC Mission walkthrough. The biggest challenge here is recognizing when the objective changes and hitting the correct submarine component immediately.
