| | Nuclear Depth Bomb - Wikipedia, the free encyclopedia |
 | | A Nuclear Depth Bomb (NDB) is the nuclear equivalent of the conventional depth charge and is used in Anti-Submarine Warfare (ASW) for attacking submerged submarines. |
 | | Due to the use of a nuclear warhead of much greater explosive power than that of the conventional depth charge, the Nuclear Depth Bomb considerably increases the likelihood of the destruction of the attacked submarine. |
 | | Because of this much greater power some NDB's feature a variable yield, whereby the explosive energy of the device may be varied between a low setting for use in shallow or coastal waters, and a high yield for deep water open-sea use. |
