US media check the oldest weapon of the US Army in service and the 60 year old bomber.

The American "mass machinery" monthly published in May 22nd, entitled "the oldest three weapons in the The Pentagon arsenal", says the United States is still using a considerable number of old weapons as a country with a defense budget of up to $600 billion. Some of the old weapons are still in use because they are very good in performance and there is no better weapon to replace. In other cases, the plan to develop alternative weapons is usually a failure because it is too complicated or too costly.

Volkswagen has excavated three oldest weapons that are still in service: M2 heavy machine guns, KC-135 tankers and B-52H bombers.

M2 heavy machine gun

The M2 heavy machine gun is the undisputed survivor of The Pentagon. This year is the 100th anniversary of M2. M2 was developed by legendary machine gun designer John Moses Browning. General Browningenjohn Pershing's request designed this heavy machine gun for trenches of World War I.

Today, the armed forces are still using the M2 machine gun. The army usually uses M2 as a chariot driver, including the tank hands of the M1A2 "Abrams" tank, while the Marine Corps uses a modified M2 machine gun mounted on a tripod and a vehicle. The Navy and air force use M2 machine guns to protect warships and air bases. M2 is an air-cooled machine gun that can shoot 450 to 550 rounds per minute, with a range of 1250 yards (1 yards of about 0.9 meters) and an inch thick armor plate within 1000 yards.

Although the basic design will be improved occasionally, there is no machine gun that can replace M2. This machine gun is likely to serve until twenty-second Century.

KC-135 tanker

During the cold war, the US Air Force bought 732 Boeing 707 commercial airliners and converted them into tankers. The KC-135 tanker is equipped with air refueling telescopic trusses and enough internal fuel storage to transfer up to 32200 gallons of fuel to fuel - deficient fighters, bombers, and transport planes. The KC-135 tanker can also transport 41.5 tons of cargo at once in the internal cargo hold.

Boeing began delivering the KC-135 tanker in 1957, and the KC-135 air refueling fleet supported the strategic air command bombers' flight patrols to the Soviet Union, the US bombing of Vietnam, and even the "Desert Storm" in 1991. The US Army is still using 414 KC-135 tankers today. Although each aircraft has a history of 58 years on average, the KC-135 tanker brigade will have to fly for several decades, and there is no substitute for it at present.

B-52H strategic bomber

The B-52H bomber was developed to carry thermonuclear bombs to the Soviet Union. Shortly after the Second World War, the B-52 bomber was designed, the first flight in 1952. The first B-52H bomber was delivered in 1961, and the last one was delivered in 1963.

Today, the US air force is still using 76 of the first 102 B-52H bombers. The arms control agreement and the abandonment of weapons platforms forced the bomber to be converted into a conventional bomber, and the ability to carry nuclear weapons was permanently abandoned.

The air force plans to re configure the bomber to reduce costs and enhance reliability, so that they can be used until 2030s. By then, the average age of the B-52H bomber fleet will reach 70. In the three bombers currently serving in the air force flying group, B-52H will be the last to retire after the B-1B bomber and the B-2A bomber.
