Hydrostatic fuze

Hydrostatic fuzes act under the influence of water pressure to explode a bomb at a predetermined depth when used against submarines or other underwater targets...

The ship s sonar provides submarine position data to a predictor which computes mortar aiming position. The triple-barrelled mortar fires a pattern of three mortar bombs which are programmed to give a three dimensional expl pattern ahead of the target. The bombs can be set to expld at variable depths using hydrostatic fuzes, and are also fitted with delayed action fuzes...

A fuze is a complicated mechanical device, metallic or plastic, housing combustible and/or explosive components in a row known as "train". It is designed to initiate an item of ammunition on being subjected to one of the following actions stab, percussion, friction, mechanical time, chemical, electrical or hydrostatic pressure... 

Fuze, Hydrostatic. A fuze employed with depth bombs or charges to cause underwater detonation at a predetermined depth. Initiation is caused by increasing ambient water pressure... 

Fuze, Mine. A fuze designed to initiate a train of fire in a land mine. For initiation of underwater (sea) mine a device known as "Firing Mechanism, Underwater Mine" It is a device contg combustible or explosive components, which can be actuated by an acoustic signal, impact, hydrostatic pressure, and/or magnetic influence (Ref 40a, pp 71...

There is also in some bombs, the transverse fuze which is fitted into a cavity of the body at right angles to its axis. The latter type of fuze, when used in depth bombs, is activated by pressure of water(hydrostatic, also called thwartship fuze)... 

They are usually loaded with HBX, HBX-1 or TNT (70% of the total wt of the bomb) and provided with a hydrostatic tail fuze that functions at a predetermined depth. A nose fuze that functions with instantaneous action on impact may be used to produce a surface burst, when the bomb is used against a surface target(Refs 7,9 15) (See Fig)... 

Each depth charge is provided either with a hydrostatic exploder (whichdetonates the chge at a predetermined depth below the surface of the sea), or a contact fuze. In order to sink or damage a submarine, the depth chge must explode in the immediate vicinity of the target, no matter what its depth is... 

Fuse/Fuze (English text only) Although these two words have a common origin (French fusee, fusil) and are sometimes considered to be different spellings, it is useful to maintain the convention that fuse refers to a cord-like igniting device whereas fuze refers to a device used in ammunition which incorporates mechanical, electrical, chemical or hydrostatic components to initiate a train by deflagration or detonation. UN App. B... 

Fuzes Articles designed to start a detonation or a deflagration in ammunition. They incorporate mechanical, electrical, chemical or hydrostatic components and generally protective features. The term includes Fuzes, Detonating Fuzes, Detonating with protective features Fuzes, Igniting. UN App. B, ICAO A2, US 173.59, lATA App. A...
