Testbed aircraft resources include the following:
The 412 Test Wing, located at Edwards AFB, CA, provides highly instrumented uniquely designed aircraft for flight testing a variety of EW systems, sub-systems, and components. The fleet consists of 39 test platforms including: C-135, C-141, T-39, T-37, C-18, and C-21 aircraft. The Test Wing can also perform Class II (RDT&E) modifications to test aircraft.

Big Crow Aircraft. The Big Crow aircraft is a large-bodied NKC-135A with an extensive EW suite. It was designed to perform vulnerability investigations on US Army weapon systems. It has several types of emitters, including nose, and tail jamming antennas and upper and lower canoe radomes. The aircraft is based at Kirtland AFB NM.

Little Crow Aircraft. Little Crow aircraft consist of two T-39Bs designed to carry EW jammers. They support the US Army's SAM-D susceptibility and vulnerability testing at the White Sands Missile Range. The aircraft are based at Holloman AFB NM.

ECM Target Aircraft (ETA). The ETA is a modified T-39B aircraft to serve as a flyable instrumented testbed used in the development of radar ECCM.

Electronic Counter Countermeasures/Advanced Radar Testbed (ECCM/ARTB). This specially modified C-141A aircraft is an airborne laboratory for testing current and future airborne radars. Its design incorporates the necessary mechanical and electrical interfaces for APG-63, 66, 68, and APQ-164 airborne radars.
