These are 10 of the longest-serving weapons in the US combat arsenal
As far as weapon systems are concerned, having the best available can be key to success on the battlefield. But with rapid changes in technology, some weapons come and go rather quickly. Other times, weapons are so well designed and so effective, they stay in service for decades.
Here are 10 of the longest-serving weapons ever used by the United States military
1. M1903 Springfield .30 Cal Rifle
The M1903 was one of the first rifles to use the famous .30-06 round and was the standard American infantry rifle during World War I. Although officially replaced by the M1 Garand in 1937, it was still in service due to insufficient numbers of Garands. The Springfield .30 cal was retained as a sniper rifle through the Korean War and even into Vietnam before finally being retired after over 60 years of service.
2. M1911 .45 Cal Pistol
The M1911 is a creation of the legendary gunmaker John Browning, and it endured in service for over 100 years. The pistol became an icon for its strength in battle and by those who used it. The M1911 was phased out in favor of the Beretta M9 9mm pistol in the late 1980s but has stayed in service with Marine Special Operations units and is now designated as the M45.
3. M1919 .30 Cal Machine Gun
The M1919 was another one of John Browning's successes. An air-cooled version of the M1917 that served U.S. troops well in World War I, it saw extensive use in World War II and Korea. The M1919 was phased out in favor of the new M60 in the late 1950s. However, the Navy, having a surplus of the weapons, converted many to 7.62 mm and used them on gun boats patrolling the rivers of Vietnam.
4. M2 .50 Cal Machine Gun
The "Ma Deuce" is a weapon system loved by the troops who use it and feared by those it targeted. The gun was designed near the end of World War I, too late to see service, and entered full production in 1921. Also designed by John Browning, the weapon is so well-built that in 2015 a 94 year old example was found still in service. Though numerous other designs have been proposed, the military has no plans to stop using the M2 anytime soon.
5. B-52 Stratofortress
The B-52 was designed to deliver nuclear weapons against the Soviet Union during the height of the Cold War. Despite never having to conduct this mission, the B-52 has been the workhorse of conventional bombing campaigns for more the 60 years. The Air Force plans to keep it in service into the 2040s.
6. M60 .30 Cal Machine Gun
The M60 entered service in 1957, just in time to see heavy use in the jungles of Vietnam. The M60 served as the standard machine gun for the U.S. military until the 1990s when the M240 was adopted. However, more than 50 years later, the M60 continues to serve with some SEAL teams and as helicopter armament.
7. M14 .30 Cal Rifle

The M14 had a short service life as the standard American infantry rifle from 1959 to 1964 when it was replaced by the M16. But the rifle never left service and was the basis for the M21 and M25 sniper rifles before making a serious comeback during the Global War on Terror when it was upgraded to the M14 Enhanced Battle Rifle.
8. M16 5.56 mm Rifle/ M4 Carbine
Since replacing the M14 in 1964, the M16/M4 family of rifles has become the longest-serving standard rifle for the U.S. military. Despite its troubled beginning, the M16 and M4 have earned a hard-fought reputation as reliable and effective weapons. Despite numerous attempts to replace it, no competition has yielded a better rifle.
9. LGM-30 Minuteman Ballistic Missile
The Minuteman intercontinental ballistic missile has served as part of the U.S. nuclear triad since entering service in 1962. The Minuteman was the first ICBM to employ multiple independent reentry vehicles, allowing each missile to deploy three separate warheads for greater chances of target destruction. The Air Force, responsible for the missiles, currently operates 450, down from the peak of 1,000 during the 1970s.
10. M61 Vulcan 20 mm Cannon
The M61 is the United States' primary armament for fixed-wing aviation. After entering service in 1959, the gun saw extensive use in Vietnam by all branches fighting in the skies. The gun was credited with shooting down 39 MiGs during the war. After over 50 years of service, the M61 is still found on American fighters and in the Navy's Phalanx CIWS.
