Gun-Fire Control System Mk 8 (GSA 8) - Early Engagement

The International Guns, Missiles & Rockets (IGMR) team within DE&S is conducting early market engagement to gain an understanding of the potential level of interest in the market and give suppliers the opportunity to comment on the procurement strategy for the provision of Gun-Fire Control System Mk 8 (GSA 8) equipment In-Service Support. The requirement is to assist the Authority in maintaining availability and capability of the GSA8 system as fitted in T23 Frigates and shore establishments. The potential contract value is up to 1.5M over 16 months (from 1 Feb 2023 till 31 May 2024). At the end of this 16-month period combined support for GSA 8 and GSA9 systems over a longer period may be explored. Background: GSA8 is the current Gun Fire Control System (GFCS) for the 4.5 Mk8 Medium Calibre Gun (MCG) fitted to the T23 Frigates, in conjunction with the General-Purpose Electro Optical Director (GPEOD) which provides Situational Awareness (SA) and visual target tracking. GSA8/GPEOD has been in service since 1988 and there have been significant obsolescence issues. Since 2021 the T23 population has commenced a gradual draw down of hull numbers and in 2035 the final T23 is due to reach her Out of Service Date (OSD). The intention is for the GSA8/GPEOD systems recovered from T23s, as they each have their own individual OSDs, to be made available to augment current stores holdings and support the remaining T23s.
