Home›Weapons Systems›Caliber›40mmBrowse By40mmThis dimension groups weapon systems by their caliber. Wikipedia notes that weapons range "from simple implements such as clubs and swords to complicated modern firearms, tanks, missiles and biological weapons," firearms whose bore size is measured precisely as caliber. Browsing by caliber keeps weapon systems built to the same specification grouped together.Facts40mmConnectionsSourcesComments (0)Reader Challenges (0)FactsComparisonEarliest Era RepresentedWell-attestedAncient 140mmFilter Results28 entriesWeapon FamilyAllAnti-Aircraft Guns (3)Anti-Tank Weapons and Mines (1)Armored Cars and Reconnaissance Vehicles (2)Assault Rifles (1)Assault Rifles of Russia and the Soviet Union (1)Grenade Launchers (7)Ground-Attack Aircraft and Gunships (1)Infantry Fighting Vehicles and Armored Personnel Carriers (1)Other Small Arms and Personal Weapons (6)Remote Weapon Stations (1)Rifles and Carbines (1)Tanks (5)Weapon Type or ClassAll40mm automatic grenade launcher (1)40mm grenade launcher (1)Anti-aircraft autocannon (1)Anti-tank rocket launcher (1)Armored fighting vehicle (1)Automatic anti-aircraft gun (1)Automatic grenade launcher (3)Bullpup assault rifle (1)Cruiser tank (2)Grenade launcher (1)Gunship aircraft (1)Infantry fighting vehicle (1)Infantry tank (3)Remote weapon station (1)Revolver grenade launcher (1)Rocket-propelled grenade launcher (1)scout car (1)Self-propelled anti-aircraft gun (1)small arm (3)Under-barrel grenade launcher (2)Introduced EraAll1934 (2)1939 (1)1940 (1)1941 (3)1942 (1)1953 (1)1960 (1)1961 (2)1967 (1)1968 (1)1969 (1)1974 (1)1978 (1)1982 (1)1983 (1)1985 (1)1990 (1)1991 (1)1993 (2)1994 (1)1997 (1)1998 (1)2006 (2)Service StatusAllIn Service (18)Prototype or Experimental (1)Retired (7)OperatorAllArgentine Armed Forces (1)Australian Defence Force (3)Brazilian Army (3)British Army (4)Bundeswehr (1)Canadian Armed Forces (4)Egyptian Armed Forces (3)Finnish Defence Forces (2)French Armed Forces (2)Indian Army (1)Israeli Defense Forces (1)Mexican Armed Forces (2)Red Army (1)Russian Armed Forces (3)Russian Ground Forces (1)Soviet Armed Forces (1)Spanish Armed Forces (1)Turkish Armed Forces (2)United States Air Force (1)United States Armed Forces (2)United States Army (3)United States Navy (1)Vietnam People's Army (1)Wehrmacht (1)Wars Used InAllCambodian Civil War (2)Falklands War (3)First Chechen War (3)Gulf War (3)Iraq War (7)Korean War (2)Laotian Civil War (2)Russo-Georgian War (1)Russo-Ukrainian War (3)Rwandan Civil War (1)Second Chechen War (3)Sino-Indian War (1)Six-Day War (1)South African Border War (2)Soviet-Afghan War (3)Sri Lankan Civil War (2)Syrian Civil War (6)Vietnam War (7)War in Afghanistan (2001-2021) (5)World War II (4)Yemeni Civil War (2)Yugoslav Wars (1)ManufacturerAllBAE Systems AB (3)Bofors (2)Cadillac (1)Colt's Manufacturing Company (1)Daimler Company (1)Denel Land Systems (1)General Dynamics Corporation (2)General Motors (2)Heckler & Koch (2)KBP Instrument Design Bureau (2)Kovrov Machine-Gun Factory (1)Lockheed Martin (1)Milkor (Pty) Ltd (1)New South Wales Government Railways (1)Niewiadów S.A.
