Lists on the subject

The CBU-55 is a US cluster bomb that contains three small aerosol bombs.

description

The CBU-55 was developed from 1970 by Honeywell in cooperation with the Naval Weapons Center China Lake . At the beginning of 1975 the first copies were delivered to the US armed forces. The CBU-55 cluster bomb can be dropped from airplanes and helicopters. The bomb is suitable for fighting vehicles, materials, buildings and field fortifications. The CBU-55 can also be used to clear large minefields. After the Second Gulf War in 1991, the remaining bombs were sorted out and demilitarized from 1996 onwards .

function

The CBU 55 is provided with three BLU-73 - Aerosol loaded -Kleinbomben. The small bomb has a cylindrical body. This is 69.6 cm long, has a diameter of 34.5 cm and weighs 59 kg. The small bomb contains 33 kg of ethylene oxide as an aerosol substance (active charge) . After being dropped from an airplane or helicopter, the FMU-83 detonator detonates the bomb skin after a preset time and the three BLU-73 small bombs are ejected from the bomb body. Your fall is stabilized and slowed down by a parachute . The dismantling charge is activated around 9 m above ground by a proximity fuse. This generates an aerosol cloud from the ethylene oxide with a diameter of around 15 m and a height of 3 to 5 m. At the same time, the 1.22 m long stick -shaped FMU-95 distance fuse is deployed on the small bomb . As soon as it comes into contact with the ground, the aerosol cloud is detonated . This creates a fireball with a temperature of over 2,600  degrees Celsius and an overpressure of 18 to 20  bar . The initial speed of the pressure wave is around 1,800 m / s. If the aerosol cloud does not detonate, the target area will be contaminated by the toxic ethylene oxide .

variants

  • CBU-55 with litter bin SUU-49 / B for use from slow-flying aircraft and helicopters
  • CBU-72 with spreader box SUU-49A / B for use in fast-flying aircraft

commitment

The CBU-55 and CBU-72 were used during the Vietnam War , the US invasion of Grenada and the 1991 Gulf War in Iraq. During this conflict, 254 CBU-72s were dropped from United States Navy aircraft . The Israeli Air Force deployed the CBU-72 during the 1982 Lebanon War .
