Broken Truce is the fifth mission of the original Ace Combat 3: Electrosphere and is the first mission in the UPEO (II) Arc.

Mission Story[]

"The members of SARF have received a secret message from Commander Park. The ceasefire agreement from the day before had been broken, and a General Resource unit was already beginning an attack against Neucom. In order to prevent any more combat between the two, the SARF members sallied out for the NEU Air Force Base.[1]"
Ace Combat 3: Electrosphere - Namco Official Guide Book


Despite the ceasefire,
General Resource forces are staging an attack against a NC base.
In order to preserve the ceasefire,
combat between the two must be avoided.
Defend Neucom's Air Force Base.

Aircraft Selection[]

EF2000E Typhoon II
MiG-33 Fulcrum SS
F/A-18U Hornet ADV
F-16XFU Gyrfalcon


Mission Start[]

The mission's primary targets are four F-15S/MTs, mixed in with four F-16XAs. The player must destroy these fighters while defending the Neucom air base and their parked R-201s. Abyssal Dision and Keith Bryan are present, flying a F-22C Raptor II and a F-16XA respectively, but cannot be targeted and will not interfere.

If the player destroys the four F-15S/MTs after 2 minutes and 59 seconds have passed, the mission ends and the player earns Mission Over, restricting them to a D Rank.[2]

Mission Update[]

If the player destroys the four F-15S/MTs within 2 minutes and 59 seconds, a pair of B-1C Lancers will spawn, with three F-16XAs as escorts. Shooting down the B-1Cs ends the mission and awards Mission Accomplished.
