General Electric's VT Radio Proximity Fuze, produced using Christmas tree lamp bulb machines, was crucial in combating Kamikaze attacks during WW2. Over 30 million glass capsules were manufactured, each designed to shatter and activate a battery, triggering a radio wave detonation within 70 feet of a target. The engineering challenge involved creating glass durable enough for firing but fragile enough for activation.

Quick Summary

General Electric's VT Radio Proximity Fuze was vital in WW2, producing over 30 million glass capsules using Christmas tree lamp bulb machines. It detonated projectiles within 70 feet of a target, effectively countering Kamikaze attacks by using a radio transmitter activated by an electrolyte-released battery.

Frequently Asked Questions

What was the primary role of the VT Radio Proximity Fuze in WW2?

The VT Radio Proximity Fuze was a critical defense system developed by General Electric, primarily used to counter Kamikaze attacks by detonating projectiles near enemy aircraft, significantly improving anti-aircraft effectiveness.

How did the VT Radio Proximity Fuze activate?

Upon firing, a glass capsule released electrolyte to activate its battery. A miniature radio transmitter then emitted waves; if these waves reflected off a target within approximately 70 feet, the fuze triggered detonation.

What manufacturing challenges did GE face with the VT Fuze capsules?

The glass capsules needed to be robust enough to withstand firing forces in both rockets and shells, yet fragile enough to break and activate the internal battery upon launch.

What unusual production method did GE use for the VT Fuze?

General Electric repurposed machinery originally designed for manufacturing Christmas tree lamp bulbs to produce the millions of glass capsules required for the VT Radio Proximity Fuze during the war.
