Description
The maximum influence radius varies between 40 and 100 feet for different lots and Mods. Sensitivity to aircraft flying below 200 ft altitude will be reduced by the wave suppression feature. Burst heights over water will average between 5 and 15 feet.
Random bursts of rounds will occur along the trajectory after arming, so that approximately 20 per cent of the rounds will have functioned before reaching a target at long range. When fired at a target at long range, after 20 percent of the rounds have burst prematurely, 65 percent will function.
This fuze is used for antiaircraft work for ranges of 500 yards to the extreme range. It is useful against low flying aircraft and surface craft, and in land barrage against personnel and light equipment.
The Auxiliary Detonating Fuze Mk 44 is used with this VT Fuze.
The VT Fuze Mk 58 is currently replacing the Mk 45 Mod 12 in the 3"/50 assembly.
Mods 3, 4, and 5 have additional water resistance and are not interchangeable with previous Mods.
Mod 5 will have a self destructive switch to function at a range of 6,000 to 9,000 yards. The switch is not adjustable.
Mod 0 is now obsolete.
