HMS Sutherland

The UK Royal Navy’s Type 23 Duke-class frigate HMS Sutherland (F81) has successfully conducted gunnery exercises before its six-month deployment in the Indian Ocean.

The gunnery trials were carried out as part of naval gunfire support exercises under the guidance of the British Army’s 148 Battery Royal Artillery, which served as specialist observers to validate the ship’s weapon system capabilities.

During the trials, HMS Sutherland test-fired up to 200 rounds a minute from its automatic set 30mm cannon, with each round travelling at about 3,500ft a second and reached a maximum range of 5km.

The vessel also fired its main 114mm gun, with shells travelling at a speed of 1,705mph, reaching a greater range of about 12km.

Armed with eight Harpoon surface-to-surface missiles in two four-cell launchers and vertical-launch Seawolf, HMS Sutherland features surface ship command system (SSCS) and four 324mm torpedo tubes to carry BAE Systems-built Stingray lightweight torpedoes.

Additional features of the vessel include radar systems, such as BAE Systems Type 996 (AWS-9) E/F band 3D search radar, Kelvin Hughes Type 1007 I-band navigation radar and two BAE Systems Type 911 fire control radars associated with the Seawolf missile system.

Powered by a diesel-electric and gas (CODLAG) system, Sutherland is also integrated with countermeasures systems, such as four Sea Gnat (Outfit DLB) decoys and a Type 182 towed torpedo decoy.

During its deployment, known as ‘Operation KIPION’, HMS Sutherland will take over the role of HMS Westminster to support counter-piracy operations, as well as surveillance for counter-drug, people and weapon trafficking within the areas of Indian Ocean, the Gulf of Oman and the Gulf.
