Sea Giraffe
Giraffe is a family of G/H (formerly C-band) frequency agile, low to medium altitude pulse doppler air search radars and combat control centers which can be used in mobile or static short to medium range air defense applications. Giraffe is designed to detect low-altitude, low cross-section aircraft targets in conditions of severe clutter and electronic countermeasures.

GIRAFFE uses Agile Multi-Beam (AMB), which includes an integrated Command, control and communication (C3) system. This enables GIRAFFE to act as the command and control center in an air defense system, it can also be integrated into a sensor net for greater coverage.

Full and fast coverage - The agile multi-beam function scans the entire search volume to 70o in every single scan with a fast scan-rate of 60 rpm.

Sea GIRAFFE is the naval variant of the GIRAFFE radar. It can detect air and surface targets from the horizon up to a height of 20,000 metres (66,000 ft) at elevations up to 70°, and can simultaneously handle multiple threats approaching from different directions and altitudes, including diving anti-ship missiles. Also, it is specialized for rapidly detecting small, fast moving targets at all altitudes and small surface targets in severe clutter. Its roles include :

  • Air surveillance and tracking
  • Surface surveillance and tracking
  • Target identification for weapon systems
  • High-resolution splash spotting

The AN/SPS-77 is multi-role medium-range 3D surveillance radar system for naval applications. It provides medium range, simultaneous air and surface surveillance and can be employed in a weapon designation role. The SPS-77 is suitable for demanding naval environments from the littorals to blue-water operations.

The radar system is being adapted for U.S. operations by the Sensor Systems division of SDAS. The division, located in Syracuse, New York, is also responsible for the integration, installation, and testing of the AN/SPS 77 systems as well as for providing in-service sustainment and repair services.

Saab, a Swedish defense and aerospace company, is creating a new U.S.-based company called Saab Defense and Security USA. SDAS incorporates previously separate divisions Saab Training USA, Saab Barracuda, Saab Support and Services, and parts of Saab Sensis Corporation.

But there may not be as many LCS to put it on. These are supposed to replace the OHP class frigates, which are being taken out of service and sold off to foreign navies.

In a move long expected by analysts and critics, the Pentagon has instructed the Navy to cut its littoral shipbuilding program by almost 40 percent to 32 vessels, according to two defense-industry press reports, but the Navy is maintaining course and speed:
