The CBU-100 Cluster Bomb (also called the Mk-20 Rockeye II) is a cluster bomb which is employed primarily in an anti-tank mode. It weighs 490 pounds and carries 247 Mk 118 Mod 0 bomblets.

The antitank bomb cluster is an air-launched, conventional free-fall weapon. The Mk 20, CBU-99, and CBU-100 are used against armored vehicles.

When the Mk 20 bomb cluster is released from the aircraft, the arming wires (primary and/or optional arming) are pulled sufficiently to arm the Mk 339 fuse (and recently the FMU-140 fuse) and release the fins. The positive armed fin release arming wire frees the fin release band, and the movable fins snap open by spring-force. Functioning of the fuse initiates the linear shaped-charges in the dispenser that cut the dispenser case in half and disperse the bombs/bomblets. When the Mk 339 Mod 1 primary fuse arming wire is pulled, the fuse will function 1.2 seconds after the arming wire has been extracted. If the pilot selects the option time (4.0 seconds), both the primary and option arming wires must be pulled. If the pilot selects the option time and the primary arming wire is not pulled, the fuse will be a dud.

Each bomblet weighs 1.32 pounds (600 g) and has a 0.4-pound (180 g) shaped-charge warhead of high explosives, which produces up to 250,000 psi (1.7 GPa) at the point of impact, allowing penetration of approximately 7.5 inches (190 mm) of armor. Rockeye is most efficiently used against area targets requiring penetration to kill. Fielded in 1968, the Rockeye dispenser is also used in the Gator air-delivered mine system. During Desert Storm US Marines used the weapon extensively, dropping 15,828 of the 27,987 total Rockeyes against armor, artillery, and anti-personnel targets. The remainder were dropped by Air Force (5,345) and Navy (6,814) aircraft. [1]
