- This article is about an in-game mission. For the in-universe event, see Operation Crossroad.
Heartbreak One is the 26th campaign mission of Ace Combat 5: The Unsung War, but is treated in the game as Mission 25. Razgriz Squadron must defend Captain Bartlett as he and the "Major" attempt to rescue Yuktobanian Prime Minister Nikanor.
Captain Bartlett has rescued Prime Minister Nikanor of Yuktobania. He plans to attack an airfield in northeast Yuktobania, steal an airplane, and then escape with the Prime Minister. First, go to the directed area and wait for contact from Captain Bartlett. He'll likely have you support him as he forces his way into the airfield. More mission details will be supplied to you upon arriving at the local airspace. Threat status in the area of operation is unclear, so prepare your flight for the possibility of threats from both the ground and the air.
- "According to Captain Bartlett's information, the resistance has already infiltrated the airfield and is currently awaiting his arrival. The road to the airfield is covered with checkpoints and defensive positions. We anticipate stiff resistance. Provide close air support for Captain Bartlett's charge, give him aerial reconnaissance as necessary, and guide him to the airfield. The resistance has already agreed on a time to begin operations with Captain Bartlett, so the timing of the mission cannot be changed. If you do not arrive in time, the resistance will be suppressed by the airfield defense forces, and the mission will end in failure. After arriving, the resistance will load Prime Minister Nikanor onto a captured transport plane, and Captain Bartlett will attempt to escape. You must help Captain Bartlett arrive at the airfield on time, no matter what."
- ― In-flight briefing
Bartlett's convoy will begin driving towards the airfield. The player must defend the convoy from all Yuktobanian aircraft and ground forces. Every time the convoy reaches a CHECKPOINT, the player must destroy it to allow the convoy to advance.
The convoy has about 11 minutes 30 seconds to reach the airfield. The convoy will reach three forks in the road along the route, and Bartlett will ask the player which way to go. Shortcuts will have more ground enemies, but detours will take longer. The player must make a decision on which path to take depending on their ammo, damage to the convoy, and how much time has passed.
|1||3 checkpoints||2 checkpoints|
|2||3 checkpoints||2 checkpoints|
|3||1 checkpoint||No checkpoints|
Once Bartlett's convoy reaches the airfield, they will take command of a C-1 and attempt to take off. The player must continue supporting them by destroying Yuktobanian tanks at the airfield as well as remaining Yuktobanian aircraft.
After Bartlett successfully takes off, the Grabacr Squadron enters the combat area. The player and the rest of Razgriz Squadron must shoot down all Grabacr pilots to complete the mission.
- YA-10B "Distant Thunder": SP New Game -> Normal difficulty or higher; spawns north of the player's initial spawn point after Grabacr appears; unlocks the SP color for the YA-10B
Earning an S rank on this mission requires completing the entire mission within 15 minutes. The player should instruct Bartlett to take all three shortcuts and eliminate all opposing forces as fast as possible.
The 8492nd Squadron...or, the Belkan Grabacr Squadron to be more exact, has been annihilated. Yuktobanian Prime Minister Nikanor is also safe. Mission accomplished.
