AN/TPS-77

Total Production: 36

Unitary Cost: USD$22 million

Also Known As: TPS-117

Origin:United States of America

Contractor/s: Lockheed Martin

Description: The AN/TPS-77, formerly known as the TPS-117, is a mobile, active phased array, long range, L-band, 3D solid-state radar designed to perform airspace surveillance missions. It shares about 80-90% Line Replaceable Units (LRUs) and maintenance activity with the AN/FPS-117 fixed position radar system, and similar performance than the FPS-117 and the TPS-59 radars. The TPS-77 incorporates COTS technology.

The TPS-77 radar can be deployed in a single C-130 and by only two medium trucks. It can be operated by a crew of 6 and set up can be done in less than 30 minutes. The radar system provides detection and tracking against targets ranges out to 280 miles (+450 km) and at elevations up to 100,000-ft (30,000).

On August 23, 2004, the US Air Force awarded Lockheed-Martin a $14.7 million contract for the supply of a second AN/TPS-77 transportable radar system for the Pacific Alaska Range Complex, the largest supersonic training area in the United States. The Air Force will control the two radars remotely from Eielson Air Force Base in Fairbanks. The radar system will be supplied with a straight-forward software upgrade that enables tactical ballistic missile tracking. The radar was deployed in September 2006.

On 31 May 2005, the Royal Danish Air Force awarded Lockheed-Martin a $40 million contract for the supply of two long range TPS-77 transportable radar systems along with logistics services for a four years period. These radars were aimed at improving air surveillance over Denmark and surrounding seas. By default, these two systems will be stationed at fixed sites.

In early November 2005 the US Air Force awarded Lockheed Martin an $89 million contract for the production and delivery of six long range AN/TPS-77 transportable radar systems to Pakistan. The TPS-77 military items were provided to Pakistan under the Foreign Military Sales (FMS) program. TPS-77s were ordered in support of Pakistan's air defense operations.
