These have been replaced with MSI Defence Systems DS30 mk2 automatic 30mm guns as part of a contract placed in September 2005. There are also two BAE Systems / Oerlikon 30mm guns with a range of 10km against the surface and 3.5km against airborne targets. The fire control system for the 114mm gun is the BAE Systems Sea Archer 30 (GSA 8) electro-optical fire control system. HMS Richmond was the first RN vessel to receive the HE ER round in April 2004. In 2001, HMS Norfolk was the first ship to be fitted with the new gun.īoth mod 0 and mod 1 guns have the capability to fire the new high-explosive extended-range ammunition developed by RO Defence, which extends the surface range to 27km. These have been being replaced with the electrically driven mk8 mod 1. The frigates were originally equipped with a BAE Systems RO Defence 114mm mk8 mod 0 gun with a range of 22km against the surface and 6km against airborne targets. Improvements include a new electronic fin actuation system for improved control and extended range and a new fuse with IR/RF (infrared / radio frequency) sensors for improved performance against very low sea-skimming targets. The new Seawolf block 2 missile entered service in July 2005. The missile division of Alenia Marconi Systems (now part of MBDA) was awarded a contract for the mid-life update of the Seawolf missile, which will include upgrading the radar tracking system and addition of infrared tracking, with sensor fusion technology. “The Type 23 frigates were originally designed for anti-submarine warfare.” VLS Seawolf is a surface-to-air missile with a command to line of sight (CLOS) guidance and radar and electro-optic tracking. Harpoon is a medium-range (90km) anti-ship missile using inertial and active radar guidance. The ships are armed with eight Harpoon surface-to-surface missiles in two four-cell launchers and vertical-launch Seawolf (GWS 26 Mod 1 VLS). The satellite communications system is the Astrium (formerly Matra Marconi) SCOT 1D. The SSCS has been upgraded to integrate the new Sonar 2087 and Outfit DLH decoy system. It is a fully distributed Ada system based on SUCCESSOR technology using Intel 80486 processors, INMOS T800 transputers and a dual fibre-optic network. The surface ship command system (SSCS) was developed by BAE Systems. It was followed by the test firing of the Martlet missile, which was fitted on an MSI Defence 30mm remote weapon station from HMS Sutherland in July 2019. The British Royal Navy conducted test firing of the Sea Ceptor air defence missile system from HMS Argyll and HMS Westminster in December 2017. ![]() This operation was to prevent the flow of illegal weapons into the hands of pro-Gaddafi forces to protect Libyan civilians. In late July 2011, British Royal Navy frigate Type 23 Duke-class HMS Sutherland conducted a boarding operation in international waters close to Libya. HMS St Albans assisted in the evacuation of UK nationals from Beirut during the Israel / Lebanon conflict, as part of the Royal Navy Operation Highbrow in July 2006. Type 23 Duke Class frigate deployments and test firings The base port of eight Type 23 frigates was changed to Plymouth and the remaining five will be based in Portsmouth. Grafton was renamed Almirante Lynch (FF-07), Marlborough to Almirante Condell (FF-06), and Norfolk to Almirante Cochrane (FF-05). Batch 1 vessels, HMS Norfolk and Marlborough, were decommissioned in 2005 and Grafton in March 2006.Īll three were sold to the Chilean Navy and delivered over 2007-2008. The UK Ministry of Defence announced that the Type 23 fleet was to be reduced to 13 in July 2004.
