The last of the Royal Navy’s Trafalgar submarines returns home for decommissioning. With her special decommissioning pennant flying, the last of the Royal Navy’s Trafalgar-class attack submarines, HMS Triumph, has arrived home in Plymouth. The boat served for close to 34 years on operations around the globe. Her pressure hull and reactor fuel is life-expired and she will never put to sea again. After storage for a couple of decades she will be recycled in Devonport.
