SDBM

The SDBM was a secondary weapon created by Project Aces for the ADA-01 ADLER, an special aircraft originally developed for Ace Combat 5: The Unsung War. Created in-universe by Gründer Industries, it was described as having a power unachieved by any other SP weapon available to the player.

Information
Within the Strangereal continuity, the SDBM was developed in the aftermath of the Belkan War by Gründer Industries, envisioned as a successor of the Multi-Purpose Burst Missile. The missile used an special warhead loaded with a polynitrogen compound, as with the MPBM.

The true power of the SDBM is comparable to a small nuclear explosion, without the hindrance of terrain contamination. The "conventional" nature of the weapon exempted it from international nuclear weapon treaties. However, it was never deployed by Gründer.
