VT Fuzes for Projectiles and Spin Stabilized Rockets


Ordnance Pamphlet 1480 (1st Rev.) describes U. S. Navy Radio Proximity (VT) fuzes for projectiles and spin-stabilized rockets, their operation, and characteristics and contains pertinent information on their usage.

VT FuzeThe various types of proximity or influence fuzes for gun projectiles, howitzer projectiles, mortar projectiles, rockets, bombs, and other missiles are designated by all U. S. Services as VT fuzes. The term VT has no significance or meaning as an abbreviation, but was devised for general usage in shipment orders, stock cards, loading lists, etc. when security requirements during the war necessitated this.
