The 11 Longest-Serving US Military Weapons

The M2, B-52 and U-2 Spy Plane are among the 11 longest serving weapons systems in the US Military

The western world is always in a rush for the latest and greatest iPhone or other tech gadgets, but troops know that some weapons systems stand the test of time without too many, if any, mods. Here are 11 of them:

1. M2 (1933)

This baby predates World War II, entering service in 1933. The M2 fires a .50-caliber round at 2,910 feet per second. It was originally adopted as an anti-aircraft weapon, but has served for decades in anti-personnel, anti-light vehicle, and anti-ship roles as well.

The B-52 Stratofortress bomber carries enough up to 70,000 pounds of ordnance on flights up to 9,000 nautical miles. Don’t worry if it needs to go further; it can refuel in the air. There are plans to upgrade the B-52’s carrying capacity to 105,000 pounds as well as computer upgrades to let this plane originally built in 1954 serve until 2040.

The C-130 Hercules was a radical, and ugly, design departure from Lockheed’s previous transport aircraft. But the ridiculed “Herk” of 1954 has proven itself over hundreds of thousands of sorties and still serves with distinction today.

It has delivered tanks at high speeddropped paratroopers, and transported supplies to every corner of the globe. An armed version, the AC-130, has supported troops in combat since Vietnam.

4. KC-135 (1956)

The first KC-135 took to the air in Aug 1956, and the flying gas station has been serving America’s best jets, helicopters, and prop aircraft ever since. Carrying up to 200,000 pounds of fuel, it has served in Vietnam, the Persian Gulf War, and the more recent wars in Iraq and Afghanistan.

5. U-2 (1956)

The high-flying U-2, famous for its reconnaissance role during the Cold War, took flight in 1956 and has received repeated upgrades ever since. Today, the U-2S can fly at 70,000 feet and is being eyed for service beyond 2050.

6. M14 (1957)

The M14 entered service in 1957 and was the standard rifle for U.S. Marines and Soldiers from 1959-1970. While it was replaced by the better known M16 for most missions from Vietnam on, improved versions have continued to see action in American hands, mostly as a weapon for squad marksmen and special operators.

7. UH-1 (1958)

The UH-1 first flew with the U.S. Army as the HU-1 in Vietnam in 1958 as an air MEDEVAC platform. It was quickly adapted for troop transport and attack missions. Today, upgraded versions of the UH-1 with a second engine serves in both the U.S. Marine Corps andAir Force as well as in foreign militaries.

8. M72 LAW (1963)

Capable of piercing nearly 8 inches of enemy armor from over 200 yards away with a 66mm rocket, the M72 Light Anti-tank Weapon was designed to give U.S. infantry a fighting chance against Russian armor in 1963. Though no longer in production, the U.S. uses stockpiled weapons to knock out light enemy armor and buildings.

9. AH-1 Cobra (1967)

Originally introduced to the military in 1967 as a stopgap solution in the Vietnam War while the AH-56 was developed. The AH-56 never materialized and the AH-1 reigned supreme until the adoption of the AH-64 Apache. While the U.S. phased out the AH-1, theMarine Corps still fields an upgraded version, the AH-1Z Super Cobra/Viper.

10. CH-47 (1962)

The CH-47A Chinook entered Army service in 1962 and were deployed to Vietnam from 1965 to 1975. Today, conventional Army units fly the CH-47F with engine, computer, and avionics upgrades from the CH-47A while the 160th Special Operations Aviation Regiment flies the MH-47G with increased fuel storage and inflight refueling capabilities.

The beloved Warthog. The A-10 Thunderbolt II is famous for its seven-barrel, 30mm gatling gun but has also been firing rockets, missiles, and bombs since 1975. It’s recent retirement plans have been indefinitely canceled.
