Description
The Mk 92 Fire Control System is a US-built medium-range anti-aircraft missile and gun fire control system. It was developed for the Oliver Hazard Perry class guided missile frigates. The system is a licensed USN version of the Thales Nederland WM-28 fire control system.

Radar Systems
The Mk 92 system can access data from the ship's air search radar, and surface search radar. The system has three radar sub-systems. The first two are combined in to a single system called the Combined Antenna System or CAS. The CAS has a track while scan radar and a tracking radar both housed in an egg shaped randome. The radars can search for, track, and illuminate targets. There is also a third radar for target illumination refered to as the Seperate Target Illumination Radar or STIR. The STIR is a radar developed from the AN/SPG-60 radar that is part of the Mk 86 gun fire control system.

Versions

 * Mk 92 modification 0 is an early version of the system for the USN.


 * Mk 92 modification 1 is the version used by United States Coast Guard cutters. It does not use the STIR or control surface to air missiles.


 * Mk 92 modification 2 is the version that was originally fit to USN Oliver Hazard Perry class guided missile frigates.


 * Mk 92 modification 5 is used by certain Saudi Arabian Badr class corvettes.


 * Mk 92 modification 6 is an upgraded version of the modification 2 as part of the CORT program. The program was canceled after being fit to two frigates

STIR Deactivated
The USN retired the Standard missile-1 from active service in 2003. Oliver Hazard Perry frigates in USN service have had the STIR radar removed.
