Tainted Peace is the 23nd mission in the Japanese version of Ace Combat 3: Electrosphere and the fourth mission in the General Resource (I) Arc.


We have detected an aircraft secretly headed for Neucom airspace. There are passengers on board who possess information critical for Neucom's side. We must prevent contact by all means. Moreover, light escort presence is confirmed, so hostilities are expected. Execute this mission in one swift strike.


The player's main objective is to shoot down the transport. Everything else, include the escorts, is optional.

The operation was a success. It appears Neucom is in disarray due to the loss of valuable talent.
