The US navy fired just one nuclear artillery shell from its ‘Atomic Annie’ gun, and that is what it regarded like
The US navy efficiently examined an atomic cannon precisely 68 years in the past on Tuesday. It was the primary and solely time that the US navy fired a nuclear weapon from a traditional cannon, according to the army.
Through the Chilly Warfare, the US navy developed many various methods of unleashing nuclear destruction on an enemy, together with a towed artillery piece constructed within the early Fifties that would fireplace a nuclear shell crammed with a lot energy. explosive than the atomic bomb that devastated Hiroshima much less. than a decade earlier.
The heavy motorized gun M65 280 mm of the military, the largest movable artillery piece ever built by the United States, was primarily based on Nazi Germany’s Krupp K5 heavy rail cannon, a devastating oblique fireplace weapon that Allied service members combating in Italy throughout World Warfare II named “Anzio Annie”.
Weighing round 85 tons, the M65 gun required two transport vans to maneuver.
In 1953, the U.S. Military moved two of those weapons by railroad from Fort Sill, Oklahoma, to a check web site in Nevada, the place crews used one to fireplace a nuclear artillery shell. throughout the first and final check of the gun’s capabilities.
Could 25, 1953, just months after an M65 gun made its very public debut at President Dwight D. Eisenhower’s inaugural parade, Military crews used a gun named “In a position Annie”, one among 20 M65 weapons ever made, fire a nuclear artillery shell.
The atomic gun check, codenamed Grable, was the 10th in the Operation Upshot-Knothole nuclear weapons test series however the one one involving nuclear artillery. The cannon, which value $ 800,000, carried out as anticipated.
About 19 seconds after the shell was fired at 0831, it detonated slightly below 8 miles away at a low burst peak of about 520 ft.
“The shell that would wipe out an enemy division exploded on the goal with roaring violence equal to fifteen,000 tons of TNT”, a historic marker at Fort Sill reads.
With this shot, “In a position Annie” grew to become “Atomic Annie”. Though the title applies to a firearm, it has been used to seek advice from M65 weapons basically.
The opposite M65 gun that was current for testing in Nevada however by no means fired was a aid gun named “Unhappy Sack”, a gun that has had a relatively uneventful historical past in comparison with Atomic Annie.
As soon as the exams had been accomplished, Unhappy Sack was to be despatched to an operational unit for an abroad deployment whereas Atomic Annie was to return to Fort Sill, however throughout the transport course of the 2 weapons had been by chance switched.
The error was not found for 10 years. The troopers who had been getting ready the weapon for the tenth anniversary of the Grable check at Fort Sill realized that the serial numbers didn’t match these of Atomic Annie, whose whereabouts had been unknown.
When the navy tried to seek out “Atomic Annie”, which was briefly renamed “AWOL Annie” throughout the search, it was a bit tough as atomic artillery items had been deployed throughout Europe and the USA. Asia, and their particular places have been labeled underline that solely a restricted variety of individuals knew precisely the place they had been.
The legendary atomic cannon was finally present in Germany and recovered. He returned to Fort Sill in 1964, and Unhappy Sack was given to the Smithsonian, according to the army.
As a result of fast tempo of nuclear weapon growth throughout the Chilly Warfare, M65 weapons like “Atomic Annie” had been out of date inside a decade of their preliminary commissioning. The M65, which was scheduled to ship a devastating nuclear strike behind enemy traces, was withdrawn from service in 1963, simply 10 years after the primary and solely shot.
In 2017, Atomic Annie cannon moved to Fort Lee in Virginia, the place he joined one other “Annie”, one of many captured German K5 railroad weapons. The big M65 cannon is a part of an academic and historic show on the new ammunition coaching help facility.
