The vessel carries a crew of roughly 100 submariners and will now undergo extensive sea trials, weapons testing, and crew preparation before becoming fully operational.
Journey and First Sea Dive
En route to the Firth of Clyde, the submarine conducted its first sea dive in the Inner Hebrides exercise areas under the surveillance of a Royal Navy Merlin helicopter. Commander John Gabb, the commanding officer of HMS Agamemnon, noted the significance of the milestone.
“It is an enormous privilege to be the first person to command this vessel at sea. We will get to know Agamemnon well over the coming months, but this submarine is incredibly quiet, has a world-class Sonar and will be home to us all as we generate for operations,” said Commander John Gabb.
The submarine’s arrival coincided with the 125th anniversary of the launch of Holland 1, the Royal Navy’s first submarine. Naval officials highlighted the tactical importance of the vessel’s integration into the fleet.
Advanced Capabilities of the Astute Class
The Astute-class submarines are recognized as the largest, most advanced, and most powerful attack submarines ever operated by the Royal Navy. Key technical features include:
- Advanced video technology replacing traditional optical periscopes to scan the horizon.
- The ability to circumnavigate the globe completely submerged while generating its own oxygen and drinking water.
- State-of-the-art sonar systems designed for ultra-quiet acoustic performance.
Armed for diverse combat scenarios, the vessel carries Tomahawk land-attack cruise missiles capable of striking ground targets hundreds of miles inland, alongside Spearfish heavyweight torpedoes capable of striking targets up to 30 miles away.
Strategic Importance to the Defence Nuclear Enterprise
Director of Submarines Rear Admiral Andy Perks emphasized the collaborative effort behind the delivery of the vessel.
“HMS Agamemnon’s delivery reflects the dedication, skill and collaboration of thousands of people across our Defence Nuclear Enterprise, who have worked together to build one of the world’s most capable attack submarines and deliver a formidable warfighting capability for the United Kingdom,” said Rear Admiral Andy Perks.
HMS Agamemnon joins sister vessels HMS Astute, Ambush, Artful, Audacious, and Anson already in active service. The seventh and final vessel of the class, HMS Achilles, remains under construction at the Barrow shipyard.
