AN/ART-13
The AN/ART-13 was a radio transmitter manufactured by Collins Radio that found widespread use during and after World War II in military aircraft.
==History==
In 1940 the Collins Radio Company designed a new radio transmitter for the US Navy. The transmitter, Navy designation ATC, was later re-designated under the Joint Army-Navy (JAN) system as T-47/ART-13. The Army Air Force adopted a slightly improved version as the T-47A/ART-13, most made by Stewart-Warner. The USAAF matched the AN/ART-13A with the BC-348 receiver, whose -R and -Q models were known under the JAN system as the AN/ARR-11. The resulting communications system was known as the AN/ARC-8 and was the liaison radio set on many larger USAAF aircraft beginning late in World War II. Some were still in service in the early 1970s.
The earlier AN/ART-13 was widely used in post-World War II Navy aircraft, being paired up post-World War II with the Navy's AN/ARR-15 auto-tune receiver. The resulting communications system was known as the AN/ARC-25. Its replacement began with the Collins AN/ARC-38 AM transceiver in the early 1950s, which in turn was upgraded to the AN/ARC-38A USB transceiver in the late 1950s. The Russians made nearly exact copies of the AN/ART-13 transmitter (called RSB-70 and R-807) for use on their military aircraft. It is thought that they obtained AN/ART-13 units from battle damaged B-29 bombers that landed in Russia during World War II. It was well known that the Russians copied the B-29 bomber calling their version the Tu-4.
Enola Gay, the B-29 Superfortress bomber that dropped "Little Boy", the first atomic bomb on Hiroshima, Japan was equipped with the AN/ARC-8 combination.〔http://aafradio.org/flightdeck/b29.htm AAFRadio – U.S. Military Aircraft Avionics from 1939 to 1945〕 The AN/ART-13 is used today by ham radio operators interested in restoring and operating historic military gear.〔http://www.radioblvd.com/art13.htm〕 It is often paired with a BC-348 military receiver of World War II vintage or the later AN/ARR-15 autotuned receiver of postwar vintage.〔http://www.collinsclubs.com/carc/b-29/radio.html B-29 Radio Project, Collins Amateur Radio Club〕
