"Shut your mouth and fire back!"
Jack Bartlett

Shorebirds is the first campaign mission of Ace Combat 5: The Unsung War. While attempting to force a spy plane to land, the player is ambushed by unknown enemy fighters and must shoot them down.


Perrault: At ease, people...but don't get too comfortable. It's a grave situation for all of us right now. Let's get this briefing started.

Briefing Officer: Another aircraft of unknown origin has entered Osean Federation airspace. We have confirmed the target type as a strategic recon plane flying at very high altitude. Despite our repeated warnings, it continued to penetrate our ADEZ and was fired upon by Osean Coastal Defense Force SAMs. We believe one of our SAMs damaged the unknown plane, but did not destroy it. Radar shows that the aircraft is currently losing altitude, and is attempting to egress feet wet towards the ocean. Intercept this target and force it to land for identification. Do not fire upon this aircraft until further orders are transmitted.



The primary focus of the mission is to follow and force a spy plane of unknown origin to land. Destroying it fails the mission. After a short time, four MiG-21bis fighters will appear from the west and attack, but cannot be targeted due to AWACS Thunderhead ordering the player to not fire.

Mission Update

After Heartbreak One gives permission to open fire, the four fighters become marked as TGTs and the player must shoot them down. Once they are shot down, another wave will spawn. This continues until the recon plane crashes or four waves spawn, whichever comes first, after which no more waves will appear. Shooting down all planes in the final wave ends the mission.[1]

  • Despite appearing solely in this level, the SR-71 Blackbird is unusually detailed. Flying close to it, one can see YAF markings on the sides and the words "Yuktobanian Air Force" painted in white letters on the top, revealing its allegiance.
  • In early concept artwork of the game's opening, the aircraft used in Nagase's introduction were aircraft highly resembling Yakovlev Yak-28 bombers.


  1. The MiG-21s will show up in waves of four aircraft each. When the SR-71 crashes ("Enemy recon plane down!"), no more waves will spawn.
  2. GIGANTOR will spawn if the player causes a third wave of MiG-21s to spawn.
