During trials earlier this year, Audacious fired an upgraded Spearfish torpedo off the Bahamas.
The Royal Navy say that five of the heavy torpedoes were fired by Audacious during three days of trials on a special range.
“The firings at AUTEC, the Atlantic Undersea Test and Evaluation Centre on Andros Island, studied the performance of the weapon at its maximum operating depth and challenged the torpedo’s homing abilities through the introduction of countermeasures.
The trials in the Bahamas were the latest in a string of crucial tests on the upgraded heavyweight torpedo since the decision was taken to enhance it in 2010. The souped-up Spearfish – known as the Mod-1 – features a new warhead, new, safer fuel system, a smarter electronic ‘brain’ and a fibre-optic guidance link with its parent submarine to improve its accuracy and lethality.
These trials took place after Initial Operating Capability was achieved, meaning work can now begin turning existing Spearfish into the improved Mod-1 version for entry into operational service with all Royal Navy submarines by 2025.”
