The Unguided Bomb (Large) (UGBL) is a bomb-type special weapon. It deals more damage and has a slightly larger blast radius than the Unguided Bomb. As with the standard UGB, the UGBL has no guidance and requires the use of a pipper to manually drop it over the intended targets. The UGBL was introduced in Ace Combat 04: Shattered Skies and has made a few appearances since then. Most UGBLs are modeled after the Mk.84 for American aircraft and larger FABs for Russian aircraft.
