Mr. W. Leon Weeks, President

Greenfield, MA 01301

Dear Mr. Weeks:

Lucien Theriault, a Raytheon retiree recalls we started a small manufacturing plant in Greenfield in about 1943 or 1944 to produce subassemblies for secret proximity fuze tubes which were being used in WWII. The proximity fuze was the third most important secret weapon which helped the Allies win WWII. The proximity fuze was in the front of anti artillery shells and mortar shells. It housed a tiny radio transmitter which sent our radio signals to enemy airplanes. These were reflected back to a tiny radio receiver also in the head of the shell. These reflected radio signals would cause the shell to explode when it was near the target, hence the name "proximity fuze". It could be set so that when near the target it would detonate. This secret invention would destroy 90% of the enemy airplanes versus 10% before. This secret invention helped turn the battle of the South Pacific in 1943, 1944 in our favor by destroying Japanese planes which were then sinking our ships and it is also credited with wining the "Battle of the Bulge" in late 1944 in Europe because of more precise mortar fire. The Japanese nor the German's had the proximity fuze.

Sincerely,
Norm Krim,
Norman B. Krim, Archivist

label levels:

There is currently no available "Beginner" label. The following is the default level label: In a letter to Leon Weeks, past President of the Museum of Our Industrial Heritage, the importance of the proximity fuze is described. The radio transmitter component of the fuse was produced in Greenfield, Massachusetts, in a secretive plant owned by the Raytheon Company. The fuse was used in shells to down enemy planes during WWII. The fuze and the manufacture of its components were well kept secrets that helped win the war.
