Sitting Duck is the first campaign mission of Ace Combat 04: Shattered Skies.


Here is the current sitrep and your orders for deployment, effective immediately. Enemy agents destroyed our early warning radar network, allowing several Bear bombers to penetrate our air space. In fifteen minutes, we expect this bomber formation to strike Allenfort Air Base, and then move on to targets at North Point. Our air defense forces are extremely weak at this point in time, hence our GHQ is a sitting duck. It is mission critical that you destroy the bombers and neutralize the threat before they get past Newfield Island. Remember, you are the first line of defense for North Point, and the fate of ISAF lies in your hands.


The mission objective is to destroy all six bombers before the time limit runs out. The bombers can bomb the city and the airbase if enough time has elapsed, but this will not affect the course of the mission.

S Rank

An S rank is achieved on this mission by obtaining 840 points before the end of the mission.[1][2] Since each bomber is worth 100 points and each escort is worth 60 points, all four escorts or the ace (240 points) must be shot down before the last bomber. Once the escorts are down, the bombers can be destroyed; the mission will then end and award the S Rank.


Thanks to your efforts, the enemy bomber strike was averted. However, our victory will be meaningless should you fail the next mission.



  • The original briefing for this mission contained an error in which the enemy bombers were incorrectly referred to as "Tu-15 Bears." The correct designation is Tu-95 Bear. The reference to the Bear's designation in the briefing has been cut from the final game.
