The AN/APS-21 is an American airborne target detection (search) radar. In game it is found fitted to high tier American, British and Japanese aircraft, in conjunction with the AN/APG-26 target tracking radar.

General info / usage

The AN/APS-21 is only a target detection radar so cannot, by itself, track targets or provide a lead indicator. However the radar is always fitted in conjunction with the AN/APG-26 tracking radar, which can track targets (albeit only at a much closer range than the AN/APS-21 is capable of detecting targets at). The AN/APS-21 has the longest maximum range of any airborne search radar currently in the game at 45 km.

Comparison with analogues

Compared to other airborne radars the AN/APS-21 has the best range of any airborne radar in the game, at a massive 45 km (with guaranteed detection at a still very impressive 28 km). The radar also has a very wide azimuth scanning angle, scanning to 85° in each direction. The radar does however have fairly poor elevation scanning angles, only able to scan 16 degrees up or down.

Pros and cons


  • Incredible 45 km maximum range
  • Guaranteed detection range of 28 km is further than other airborne radar's maximum range
  • Very good azimuth scanning angles
  • Two different search modes


  • Relatively poor elevation scanning angles
  • Fairly slow scanning, taking 3 seconds to complete a scan on the default settings (long enough that blips can begin to fade between scans).
  • Relatively high minimum range (1 km)


The AN/APS-21 was developed by the Westinghouse Electric Corporation. It was developed in the late 1940s / early 50s as part of the AN/APQ-35 radar suite for the Douglas F3D-1 Skyknight. The suite consisted of the AN/APS-21 search radar, the AN/APG-26 tracking radar, and the AN/APS-28 tail warning radar. A larger and more powerful version of the suite designated AN/APQ-36, was developed and fitted to later models of the F3D as well as the F7U Cutlass.

Despite the AN/APS-21 being fitted to the Javelin F.(A.W.) Mk.9 and Mitsubishi T-2 in game neither of these vehicles used the radar in real life. The Javelin F.(A.W.) Mk.9 used either the American AN/APQ-43 (AI.22) radar suite, or the British AI.17 radar for later models. The Mitsubishi T-2 used the Mitsubishi Electric J/AWG-11. It is unclear whether these vehicles will be given historical radars in the future or if the AN/APS-21 will be considered "close enough" to their historical radar performance.


An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
