The Type 286 was a British naval air search radar, derived from the ASV Mark I and available from shortly after the Allied evacuation from Dunkirk in France. It was the first destroyer set, designed for small ships, and was very crude, having no rotating antenna. The target area was scanned by maneuvering the ship.

The 286P introduced a rotating antenna. It also had better bearing accuracy (3-5 degrees). The 286PW was a submarine radar with about half the range.
