It was placed into service in late 1942, and by 1944 it had also been adapted for use on surfaced submarines. With some 1,000 sets eventually being built, the Type 13 was by far the most used air- and surface-search radar of the Imperial Navy. The Type 14 was a shipboard system designed for long-range, air-search applications.

Klein Heidelberg was the code-name give to a passive radar system devised in 1941. The system was a bi-static radar system. What was unusual was that the transmitters were British rather than German! The system worked by using the reflections from the Chain Home (British coastal radar system) rather than transmitters associated with the receivers.
Side view of an AN/APS-4 radar pod without its shell. The AN/APS-4, originally known as ASH (air-surface, model H) is an early military air-to-air and air-to-surface radar used by American and British warplanes during World War II. APS-4 operated in the X band at 3 cm, compared to the 10 cm S band used by most radars of the era. This allowed ...
Additionally, in high-altitude tests, it was noticed that the signal disappeared in clouds, an observation that would later give rise to weather radar systems, but in the meantime made the system less than useful. [75] The Director of Radar in the Air Ministry decided to embargo all work on the K-band systems for security reasons. [76]
The PRP was adapted from the British Army GL, Gun Laying, radar system, and first went to sea in 1939 aboard several C-class cruisers, using the Type 280 radar. By 1941 the PRP was a common feature on the Type 280, 279 and 281 radars, and by late 1941 began to appear on the type 282P, 284P and 285P radar systems. [6]
H2X, eventually designated as the AN/APS-15, [2] was an American ground scanning radar system used for blind bombing during World War II.It was developed at the MIT Radiation Laboratory under direction of Dr. George E. Valley Jr. [3] to replace the less accurate British H2S radar, the first ground mapping radar to be used in combat. [4]
Radar, Air-to-Surface Vessel, Mark III, or ASV Mk.III for short, was a surface search radar system used by RAF Coastal Command during World War II.It was a slightly modified version of the H2S radar used by RAF Bomber Command, with minor changes to the antenna to make it more useful for the anti-submarine role.
