FORACS Test Procedures for MK 92 MOD 2 Fire Control System. Standardized Testing of Modified MK 92 FCS on FFG 7 Class Platforms, at Fleet Operational Readiness Accuracy Check Sites.

The purpose of this instruction is to provide a standardized procedure for testing the MK 92 MOD 2 Fire Control System FCS installed on FFG 7 class platforms. The MK 92 MOD 2 FCS is a modified and expanded Dutch design. The system was originally intended as a gun control system, designated MK 92-1 Gun Fire Control System GFCS, which used a single antenna called the combined antenna system CAS. The CAS is comprised of a search antenna located on the lower side of a stabilized platform and a track antenna located on the upper side of this platform, with the entire assembly enclosed in a fiberglass shock-mounted dome. With the addition of a separate track and illumination radar STIR as missile control, the system becomes the MK 92-2 FCS. The MK 92-2 FCS has a capability of tracking four targets simultaneously on its three tracking antennas. The CAS track antenna can track one target, and the CAS search antenna provides data for a track-while-scan TWS system capable of tracking two targets. These two X-band systems are driven by a common transmitter through a power splitter. The STIR antenna tracks one target and is driven by its own X-band transmitter. All three systems are controlled by an ANUYK-7 digital computer, which in turn is controlled by two weapon control consoles, WCC-2 on the left and WCC-1 on the right.
