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 was a US nuclear depth bomb operational from 1958 to 1972. 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.
The UUM-44 SUBROC ("Submarine Rocket") was a type of submarine-launched rocket deployed by the United States Navy as an anti-submarine weapon. It carried a 25 kiloton tactical nuclear warhead configured as a nuclear depth bomb. [3]
Mk. 17 depth bomb is being unloaded from a SOC Seagull scout plane on board the USS Philadelphia (CL-41) during an Atlantic U-boat sweep near Panama in June 1942. Air-dropped depth bombs were normally set to explode at a shallow depth, while the submarine was crash-diving to escape attack.
Squid was a British World War II ship-mounted anti-submarine weapon. It consisted of a three-barrelled mortar which launched depth charges. It replaced the Hedgehog system, and was in turn replaced by the Limbo system.
Many submarines escaped during the time after an unsuccessful depth charge attack. Since Hedgehog charges explode only on contact, sonar tracking of the submarine is less likely to be disrupted by an unsuccessful Hedgehog attack. Proximity weapons (such as depth charges) need to be set for the target's correct depth to be effective.
The Vanguard is a class of nuclear-powered ballistic missile submarine introduced in 1994 as part of the Trident nuclear programme. Each sub costs around £3.75 billion, measuring nearly 500ft ...
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).
