The ARC-231 Skyfire is a software-definable radio for military aircraft that provides two-way, multi-mode voice and data communications over a 30 to 512 MHz frequency range. It covers both line-of-sight Ultra High Frequency (UHF) and Very High Frequency (VHF) bands with AM , FM and SATCOM capabilities, [ 1 ] including Integrated Waveform (IW).
A new version, the F4F-4, entered service in 1941 with six machine guns and the Grumman-patented Sto-Wing folding wing system, [47] [48] which allowed more aircraft to be stored on an aircraft carrier, increasing the number of fighters that could be parked on a surface by more than a factor of 2. The F4F-4 was the definitive version that saw ...
UHF-Aircraft station AN/ARC-164 HAVE QUICK II. Have Quick (also HAVEQUICK, short HQ) is an ECM-resistant frequency-hopping system used to protect military aeronautical mobile (OR) radio traffic.
The ARC-210s are manufactured by Rockwell Collins and are installed in a wide range of aircraft, helicopters and ships across all five U.S. military services. The ARC-210 program began in 1990 as an improved version of the AN/ARC-182 , adding jam-reisistant SINCGARS capability to communicate with Army radios for close air support. [ 2 ]
Radio transmissions from the aircraft report its position in three dimensions to other aircraft on the range and also to ground control. This enables real-time air-to-air exercises to be carried out and also complex ground debriefs ( after-action review or AAR) based on data recorded at the time.

Most manufacturers [2] follow the waterfall model to coordinate the design product, [3] but almost all explicitly permit earlier work to be revised. The result is more often closer to a spiral model. For an overview of embedded software see embedded system and software development models. The rest of this article assumes familiarity with that ...
