S-band target-indicator, successor to Type 293Q, using a very similar antenna. Development began in 1948 and was completed in 1952; range on an air target was up to 30nm, depending upon altitude. Fittings included the cruisers of the Tiger class. The current version, Type 992Q, uses a slotted waveguide antenna, fully stabilized, and operates as the target-designation radar in missile ships such as the 'County' class and the Type 42 and 82 destroyers. It is the principal air search radar in the Type 21 and Type 22 frigates, in analogy to similar use of Type 293Q. In larger ships it can be synchronized with other radars in pulse and in rotation. Marconi.
S-band target-indicator for frigates and similar craft, replacing Type 293Q, using a 'quarter-cheese' antenna. This has the advantage that the feed horn does not obscure the main radar beam, and the beam is better defined, even over a considerable turning band. It is being displaced in service by Type 994.
Modernized Type 993, with the same antenna but with a new transceiver based on that of the Plessey AWS-4; performance is said to exceed that of the earlier system. Installation began in 1978.
