MK91 Guided Missile Fire Control System (GMFCS)
The MK91 NATO Seasparrow Guided Missile Fire Control System (GMFCS) Rearchitecture Program integrates NATO SEASPARROW Surface Missile System (NSSMS) into the Ship Self Defense System (SSDS) Architecture to provide an additional layer of ship missile defense. This effort consists of combining the Firing Officer Console and Radar Set Console functionality into a single Advanced Display System Console (AN/UYQ 70); modifying the Signal Data Processor and eliminating the MK157 Computer Signal Data Converter, and System Evaluation and Trainer (SEAT) which cannot accommodate further upgrade; and redistributing this functionality within SSDS compatible microprocessors. This approach will eliminate the analog, point-to-point architecture, limited input-output channel and computer processing reserve deficiencies resident in the existing MK57 NSSMS, as well as allow for full exploitation of the capabilities of the future ESSM and provide significant reductions (50%) in NSSMS cost of ownership and manning.
