Crosley's company was involved in war production planning before December 1941, and like the rest of American industry, it focused on manufacturing war-related products during World War II. The company made a variety of products, including
proximity fuzes, experimental military vehicles, radio
transceivers, and
gun turrets, among other items.
Proximity fuzes The most significant Crosley's wartime production was the
proximity fuze, which was manufactured by several companies for the military. Crosley's facilities produced more fuzes than any other manufacturer and made several production design innovations. The fuze is widely considered the third most important product development of the war years, ranking behind the
atomic bomb and
radar. Ironically, Crosley himself did not have U.S. government security clearance and was not involved with the project. Without government security clearance, Crosley was prohibited from entering the area of his plant that manufactured the fuzes and did not know what top-secret products it produced until the war's end. Production was directed and supervised by Lewis M. Clement, the Crosley company's vice-president of engineering.
James V. Forrestal,
U.S. Secretary of the Navy said: "The proximity fuze has helped blaze the trail to Japan. Without the protection this ingenious device has given the surface ships of the Fleet, our westward push could not have been so swift and the cost in men and ships would have been immeasurably greater."
George S. Patton, Commanding General of the Third Army, remarked: "The funny fuze won the
Battle of the Bulge for us. I think that when all armies get this shell we will have to devise some new method of warfare."
Radio transceivers, gun turrets, and other products Also of significance were the many radio transceivers that Crosley's company manufactured during the war, including 150,000
BC-654s, a receiver and transmitter that was the main component of the SCR-284 radio set. The Crosley Corporation also made components for
Walkie-talkie transceivers and
IFR radio guidance equipment, among other products. In addition, Crosley's also manufactured field kitchens, air supply units for Sperry S-1
bombsights (used in
B-24 bombers), air conditioning units,
Martin PBM Mariner bow-
gun turrets, and quarter-ton trailers. Gun turrets for
PT boats and B-24 and
B-29 bombers were the company's largest military contract. All of these military prototypes were powered by the two-cylinder boxer engine that had powered the original Crosley automobile. One vehicle
prototype was the 1942/1943 Crosley CT-3 "Pup," a lightweight, single-passenger, four-wheel-drive vehicle that was transportable and air-droppable from a
C-47 Skytrain. Six of the Pups were deployed overseas after undergoing tests at
Fort Benning,
Georgia, but the Pup project was discontinued due to several weak components. Seven of the thirty-seven Pups that were built are known to survive. ==Later years==
