A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or another submarine, located a safe distance away.
A nuclear depth bomb is the nuclear equivalent of a conventional depth charge, and can be used in anti-submarine warfare for attacking submerged submarines.The Royal Navy, Soviet Navy, and United States Navy all had nuclear depth bombs in their arsenals at one point.
The Mk-101 "Lulu" started to be replaced by the multipurpose B57 nuclear bomb during the mid-1960s. The B-57 was a bomb that could be used by tactical aircraft against land targets, as well as a nuclear depth charge. [1] The Mk-101 "Lulu" had a length of 7 ft 6 in (2.29 m), diameter of 1 ft 6 in (46 cm), and weighed 1,200 lb (540 kg).
In contrast, out of 5,174 British depth charge attacks in WWII there were 85.5 kills, a ratio of 60.5 to 1. ... Squid bomb markings diagram.
The Mark 90 nuclear bomb, given the nickname "Betty", was a Cold War nuclear depth charge, developed by the United States in 1952. It had a length of 10 ft 2 in (3.10 m), a diameter of 2 ft 7.5 in (0.80 m), and a weight of 1,243 lb (564 kg), and it carried a Mark 7 nuclear warhead with a yield of 32 kilotons .
Air-dropped depth charges were referred to as 'depth bombs'; these were sometimes fitted with an aerodynamic casing. Surface-launched depth charges are typically used in a barrage manner in order to cause significant damage through continually battering the submarine with concussive blasts. Depth charges improved considerably since their first ...
The low kiloton [a] W55 nuclear depth bomb dropped into the water and sank rapidly to detonate near its target. A direct hit was not necessary. A direct hit was not necessary. The W55 was 13 inches (33 cm) in diameter, 39.4 inches (100 cm) long, and weighed 465 lb (211 kg).
A direct hit by a single Hedgehog bomb was usually sufficient to sink a U Boat. [11] Many depth charges were required to inflict enough cumulative damage to sink a U Boat; even then, many survived hundreds of detonations over a period of many hours. For example, U-427 survived 678 depth charges dropped against it in April 1945. The ...
