The “world’s most advanced torpedo” is almost ready for service with the Royal Navy after extensive trials in Scotland, Forces Net reports.
The Spearfish – which has been British submarines’ weapon of choice since the early 1990s – is undergoing a £270m upgrade which includes a new warhead, safer fuel system and an enhanced electronic “brain”.
Around 100 engineers and experts from BAE Systems in Portsmouth have spent nearly six years improving the torpedo, the Navy said.
