Type 984 was a

early warning

system. It was the most sophisticated naval radar of its era.

Description

The Type 984 was different from most radars in a number of ways. For one, it used a lens made of metal tubes in place of the more traditional

feedhorns, each scanning about 5 degrees vertically. Other 3D radars of the era generally picked one solution or the other, using a network of separate feedhorns or a single vertically scanning feed. The use of four magnetrons gave it better range performance; against large high-flying aircraft it had a typical range of 180 nmi (330 km; 210 mi), although this fell to as short as 40 nmi (74 km; 46 mi) against small low flying aircraft.^[2]

A key part of the overall Type 984 installation was the

US Navy aircraft during military exercises, the combination of the 984's high scanning rates and the CDS' tracking made the ships impossible to approach without being intercepted. CDS also allowed the 984 to be used both for interception control, as well as day-to-day air traffic control around the fleet aircraft carriers

.

The original design called for a maximum weight of 15 long tons (15 t), and a maximum turning circle while scanning of 25 feet (7.6 m). Many Navy designs of the early 1950s intended to mount the 984, and some sported two installations, fore and aft. As the design matured its weight continued to grow, ultimately reaching 30.5 long tons (31.0 t), making it too heavy for most ships. At the same time, the Navy's inventory of large ships was shrinking. Ultimately it was mounted on only the aircraft carriers Eagle, Hermes and Victorious.^[2]
