 Advances in fighter propulsion led to the development of the "hot warp" engine, which made possible the Fast Patrol ships which dominated the battles of the later General War period.These PFs could roam the battlespace faster than Warp 3 with surplus power for offensive weapons, yet were inexpensive and quickly built enough to replace their battle losses in all but the most savage campaigns.Importantly, the Scout PF variants had the ability to "go wild" on command and perform as a Federation SWAC shuttle acting as a Wild Weasel decoy for seeking weapons.
