Royal Navy Says New Torpedo Ready to Enter Service

The world’s most advanced torpedo is on the cusp of entering service with the Royal Navy after extensive trials in Scotland. Over four days on special ranges near the Kyle of Lochalsh, the improved weapon was put through its paces, testing both software and hardware enhancements – while the Plymouth-based frigate did its utmost to fend off the torpedo’s attacks. The upgraded Spearfish – the principal weapon of the UK’s Submarine Flotilla against enemy ships and submarines – was ‘fired’ repeatedly at frigate HMS Sutherland as scientists, engineers and sailors study its performance.

Spearfish has been the Silent Service’s weapon of choice since the early 1990s, though it has never been fired in anger. It can break the back of frigates, destroyers and similar-sized warships, and take out any underwater threats. The warhead is a good six times more powerful than that carried by the smaller Sting Ray torpedo, fired by ships like Sutherland or launched from Merlin and Wildcat helicopters. The Royal Navy is investing £270m in upgrading Spearfish, fitting a new warhead, new, safer fuel system, an enhanced electronic ‘brain’ and a new fibre-optic guidance link with its parent submarine to improve its accuracy and lethality.

A team of around 100 engineers and experts from BAE Systems in Portsmouth have spent nearly six years working on the improved torpedo, which will be introduced to front-line hunter-killer and nuclear-deterrent submarines over the next three years – and in service into the 2050s. For the latest workout at the British Underwater Test and Evaluation Centre – a stretch of water between Skye and the Scottish mainland which is ten kilometres long, six wide, up to 200 metres deep and peppered with state-of-the-art sensors – the frigate was assessed to see if she could defeat the new-look Spearfish, using a mix of evasive manoeuvres to evade the torpedo and advanced acoustic counter-measures to lure it away from Sutherland.

Anyone expecting tell-tale submarine wakes streaking through the waters was disappointed as Spearfish was set to ‘run deep’ for safety reasons – so the ‘battle’ was played out on the displays in Sutherland’s operations room. A range of military and industrial partners have come together to deliver an efficient trial which in due course will deliver another exciting capability for the Royal Navy. Following the torpedo trials, Sutherland moved on to join the Americans, Norwegians and Danes on exercise in the Arctic. A final trial of Spearfish will take place at BUTEC later in 2020 before the weapon is declared operational and begins being delivered to the submarine fleet.
