This is a list of vehicles used by the U.S. Army Signal Corps from World War I through World War II.
Vehicles specifically designed or adapted for the Signal Corps were initially designated by a "K" number. The K-number was later phased out along with the Signal Corps Radio nomenclature system, and was replaced by a "V" number under the Joint Electronics Type Designation System (JETDS).

The SCR-270 was one of the first operational early-warning radars. It was the U.S. Army's primary long-distance radar throughout World War II and was deployed around the world. It is also known as the Pearl Harbor Radar, since it was an SCR-270 set that detected the incoming raid about 45 minutes before the 7 December 1941, attack on Pearl Harbor commenced.
The SCR-268 was the United States Army's first radar system. Introduced in 1940, it was developed to provide accurate aiming information for antiaircraft artillery and was also used for gun laying systems and directing searchlights against aircraft. The radar was widely utilized by both Army and Marine Corps air defense and early warning units during World War II. By the end of World War II the system was already considered out of date, having been replaced by the much smaller and more accurate SCR-584 microwave-based system.
The SCR-584 was an automatic-tracking microwave radar developed by the MIT Radiation Laboratory during World War II. It was one of the most advanced ground-based radars of its era, and became one of the primary gun laying radars used worldwide well into the 1950s. A trailer-mounted mobile version was the SCR-784.
The gun data computer was a series of artillery computers used by the U.S. Army for coastal artillery, field artillery and anti-aircraft artillery applications. For antiaircraft applications they were used in conjunction with a director computer.
The SCR-784 was a radar set used by the U.S. Army designed to be an amphibious version of the SCR-584, to control the fire of anti-aircraft batteries, and mounted on a searchlight trailer called a K-84. The set was used to guide the flare plane over the target.
Signal Corps Radios were U.S. Army military communications components that comprised "sets". Under the Army Nomenclature System, the abbreviation SCR initially designated "Set, Complete Radio", but was later misinterpreted as "Signal Corps Radio."
The SCR-658 radar is a radio direction finding set introduced by the U. S. Army in 1944, was developed in conjunction with the SCR-268 radar. It was preceded by the SCR-258. Its primary purpose was to track weather balloons. Prior to this it was only possible to track weather balloons with a theodolite, causing difficulty with visual tracking in poor weather conditions. The set is small enough to be portable and carried in a Ben Hur trailer.
The GMC CCKW, also known as "Jimmy", or the G-508 by its Ordnance Supply Catalog number, was a highly successful series of off-road capable, 21⁄2-ton, 6×6 trucks, built in large numbers to a standardized design for the U.S. Army, that saw heavy service, predominantly as cargo trucks, in both World War II and the Korean War. The original "Deuce and a Half", it formed the backbone of the famed Red Ball Express that kept Allied armies supplied as they pushed eastward after the Normandy invasion.
The SCR-694 was a portable two way radio set used by the U.S. military during World War II.
The SCR-277 was a mobile, trailer mounted radio range set for radio guidance of aircraft. It was standardized by the U.S. Army in June 1941.
The Jeep trailer was a small, 1⁄4 short ton payload rated, cargo trailer, designed in World War II, tailored to be towed by 1/4-ton jeeps. Versions of the quarter-ton jeep trailer remained in military use, by the U.S. or other countries, at least through to the 1990s.
Ben Hur trailer was the nickname of the World War II U.S. Army Trailer, 1-ton payload, 2-wheel, cargo, and the Trailer, 1-ton payload, 2-wheel, water tank, 250 gallon. Specialized variants were also manufactured.
The BC-342 was a World War II U.S. Army Signal Corps high frequency radio receiver. It was used primarily as part of field installations such as the SCR-188A, but could be used with mobile sets such as the 2 1/2 ton mounted SCR-399. First designed at Fort Monmouth, New Jersey by the U.S. Army Signal Corps, it was built by various manufacturers including RCA. Many of the later units that are encountered today were manufactured by the Farnsworth Television and Radio Corporation of Fort Wayne, Indiana. Variants include the low frequency coverage BC-344 receiver, and the battery or dynamotor powered BC-312 receiver.
The K-50 telephone repair trucks were used by the U.S. Army Signal Corps, during and after World War II, for the installation and repair of hard telephone lines, primarily in territories liberated from Nazi Germany by the Allied forces.
The AN/MRN-1 was an instrument approach localizer used by the Army Air Force during and after World War II. It was standardized on 3 July 1942. It replaced the SCR-241, and was a component of SCS-51.
The AN/MRN-3 was a marker beacon set used by the Army Air Force during and after World War II, it was standardized 23 October 1943, and replaced SCR-241.
The Autocar Model U8144T, officially "5- to 6-Ton, 4×4, Ponton Tractor Truck", was the largest, and most heavy-duty, of a family of heavy four-wheel drive trucks developed for, and deployed primarily with, the United States Army in World War II. They were of a "cab over engine" design, and produced by the Autocar Company from 1941 to 1945 with 2,711 being built.
The K-31 truck, a US Signal Corps designation for an Autocar U8144 truck with York-Hoover van body, was used as the power truck for the SCR-270, an early warning radar of World War II. The power it delivered to the radar came from a PE-74 generator. 2) 3) 4) Similar vehicles were the K-30 and K-62 or K-62-A, all three operating trucks for the SCR-270. K-31 differed in cubic feet and overall height from K-30 and K-62. The K-62 AND K-62A were the successors of both the K-30 and K-31. Note the difference in form of the wheel arch of the van body between the depicted vehicles that shows that there must have been successive models from York-Hoover. The third image in the gallery shows that the two panels at each side were folded up when the vehicles where operated, while the panels at the back where two halves that were folded up and down respectively.
The K-30 truck, a US Signal Corps designation for an Autocar U8144 truck with York-Hoover van body, was used as the Operating Truck for the SCR-270, an early-warning radar of World War II. 2) 3) 4) Similar vehicles were the K-31 power truck for the SCR-270 early warning radar and K-62 or K-62-A, both operating trucks also for the SCR-270. K-30 and the similar K-62(-A) differed in cubic feet and overall height from the K-31. On the accompanying image in the infobox can be seen, that the K-30 beside in cubic feet and overall height differed from the K-31 in having a window on the right side of the van body. The panels at the back and at both sides were formed by two halves, that were folded up and down respectively. This truck contains a high-power radio transmitter, a cooling system for the transmitter tubes, two cathode-ray oscilloscopes, two superheterodyne receivers, a vacuum-tube keyer, a plotting table, and containers for spare parts and tubes.
