Description |
|
This fuze has a maximum influence radius of about 75 feet. Against aircraft below 200 feet altitude, operating radius is reduced, depending on the height of the trajectory and the height of the waves, because of the wave-suppression feature. Burst height over land or water will vary between 10 and 50 feet. |
|
Employment |
|
This fuze is used antiaircraft fire from a minimum range of 700 yards to the maximum range of the gun at all elevations. It is also effective against personnel and light equip-ment in shore bombardment where an aerial burst will produce fragmentation damage. |
