The '''Mark 92 Fire Control System''' is a US-built medium-range anti-aircraft missile and gun fire control system. It was developed for the FFG-7 [[Oliver Hazard Perry class frigate|Oliver Hazard Perry class guided missile frigates]]. The system is a licensed [[USN]] version of the [[Thales Nederland]] WM-25 fire control system. The Mark 92 fire control system was approved for service use in 1975. Introduction to the fleet and follow-on test and evaluation began in 1978.<ref name=GlobalSec>{{cite web|url=http://www.globalsecurity.org/military/systems/ship/systems/mk-92-fcs.htm|title=MK 92 Fire Control System (FCS)|publisher=GlobalSecurity.org|accessdate=2008-12-12}}</ref>
==Radar Systems==
[[File:MK-92 Mod 2 Functional Diagram.jpg|thumb|right|upright|MK-92 Mod 2 Functional Diagram.jpg]]
The Mark 92 system assigns targets via the ship's air search radar, and surface search radar or from the Mark 92's own search radar capabilities.<ref name=GlobalSec/> The system has two or three radar sub-systems depending on the model. The first two are combined into a single system called the Combined Antenna System or CAS is used in all models.<!-- #1.1 --> The CAS has a track while scan radar (Search) and a tracking radar both housed in an egg shaped radome. The radars can search for, track, and illuminate targets. <!-- #1.2 --> There is also a third radar for target illumination referred to as the Separate Target Illumination Radar or STIR. The STIR is a radar developed from the [[Ship Gun Fire Control Systems|AN/SPG-60]] radar that is part of the Mark 86 gun fire control system. <!-- #2.0 -->

==STIR (Separate Target Illumination Radar) Deactivated==
The [[USN]] retired the [[RIM-66 Standard|RIM-66E, or Standard missile-1]], from active service in 2003. Oliver Hazard Perry frigates in [[USN]] service have had the STIR radar removed. The STIR radars are still in use on non-USN vessels. <!-- globalsecurity.org reference -->
