Imminent Threat is the second campaign mission of Ace Combat 04: Shattered Skies.

Briefing

The enemy-held Rigley Air Base is located in close proximity to our front lines, making it the proverbial knife at our throat. A large Erusian bomber contingent was deployed to Rigley. Their intentions are clear—a full-scale strike on our forces at North Point is imminent. Your mission is to catch these bombers on the ground and destroy them. We intend to turn the parking ramp at Rigley into a junkyard.

Objectives

The player needs to destroy all of the bombers that are parked on the base. These bombers will not attempt to take off, so the mission can only fail if the player allows all fifteen minutes to elapse. In addition to enemy fighters and anti-air guns defending the base, there are also ground facilities that can be destroyed, but they are not critical to the mission.
