3. Current Uses of DU
DU is currently used in kinetic cartridges for the Army’s 25mm BUSHMASTER cannon (M2/3 Bradley Fighting Vehicle), the 105mm cannon (M1 and M60 series tanks) and the 120mm cannon (M1A1 and M1A2 Abrams Tank). The Heavy Armor variant of the M1A1, the M1A1 (HA), also employs layered DU for increased armor protection. Army Special Forces also use small caliber DU ammunition on a limited basis. The Marines use DU tank rounds in their own M1-series tanks as well as a 25mm DU round in the GAU-12 Gatling gun on Marine AV-8 Harriers. The Army uses small amounts of DU as an epoxy catalyst for two anti-personnel mines: the M86 Pursuit Deterrent Munition and the Area Denial Artillery Munition.[66] The Air Force uses a 30mm DU round in the GAU-8 Gatling gun on the A-10. The 20mm DU round developed by the Navy for use in its shipboard PHALANX Close In Weapons System (CIWS) remains in service; however, since FY 1990, the Navy has procured only tungsten rounds for the CIWS. The 20mm DU rounds remaining in the inventory will be used until the supply is exhausted or ages beyond its service life.[67]
DU is also used in numerous commercial applications:[68, 69]
ballast and counterweights
balancing control services on aircraft (civilian and military)
balancing and vibration damping on aircraft
machinery ballast and counterweights
gyrorotors and other electromechanical counterweights
neutron detectors
radiation detection and shielding for medicine and industry
shielding for shipping containers for radiopharmaceuticals, radioisotopes, and spent nuclear fuel rods
chemical catalyst
X-ray tubes
glass and ceramics for brilliant colors
