Long-Range Air-to-Ship Missile

The Long-Range Air-to-Ship Missile (LASM) (in Ace Combat 04: Shattered Skies and Ace Combat 5: The Unsung War named  Long-Range Air-to-Surface Missile) is a special weapon of the Ace Combat series. The missile is designed to destroy enemy ships at long range. The missile has high power and armor penetration, thus causing great damage to the selected target from inside. The missile has no area of destruction, therefore it is not suitable for killing groups of enemies. In the Ace Combat: Assault Horizon game there is an association between the Long-Range Air-to-Ground Missile (LAGM) and  the Long-Range Air-to-Ship Missile (LASM) mixing them into a different type named LAGM, and as a result, the missile flies to the chosen target as an anti-ship missile, but has an area of destruction as the air-to-ground missile.

Ace Combat 6: Fires of Liberation
The LASM returns in Ace Combat 6, though the weapon has undergone a modification of sorts. If the target is land based, then the missile will act like the XAGM in which it flies and then dives towards its target. However, if it is a sea based target, it will immediately dive and skim towards the target until impact. It is the most powerful incarnation of the weapon due to its blast radius and usage.
