Thanks DJ. For context, from a weaponry point of view, how much does sub carry? I know nuclear subs can stay submerged for months at a time and can be virtually undetectable, but what sort of weapons payload can they carry compared to say a surface battleship?
The last battleship, USS Missouri (displacement 58,000 tons), was decommissioned in 1992 (after featuring in "Under Siege"). The latest USN aircraft carrier, USS Gerald R Ford (displacement 112,000 tons), is by far the largest ever warship and it carries an enormous payload of aircraft and their munitions as well as surface to air missiles and other air defence weapon sustems. After the aircraft and heicopter carriers, the next largest warship would be a Kirov class cruiser (displacement 28,000 tons).
The USS Zumwalt (displacement 16,000 tons) is a stealth destroyer with the very latest suite of weapons and defensive systems. It carries 2 X 155mm guns, 2 X 30mm close defence weapon systems, 80 vertical launch cells for a range of missiles including Tomahawks, two helicopters and three UAVS with their own weaponry.
Virginia class submarines displace 10,000 tons and have four 21" torpedo tubes and 12 vertical launch tubes for missiles. They would carry 25 torpedoes and 40 missiles. The Virginia class launch tubes can also support future payloads such as autonomous vehicles, AIM-9X surface-to-air missiles and hypersonic boost-glide missiles. Astute class submarines displace 7,000 tons (the same as our Hobart class Air Warfare Destroyers) and have six 21" torpedo tubes and carry 38 torpedoes and missiles, all launched via the torpedo tubes. Our Collins class submarines displace around 3,400 tons and carry a mix of 22 torpedoes and missiles or 44 sea mines all deployed via six 21" torpedo tubes.
Our Hobart class destroyers have 1 X 5" gun, 1 X Phalanx and 2 X 25mm close defence weapon systems, 48 missile launch cells, two torpedo tubes, and one helicopter.
Basically, the Astute and Virginia class submarines are much larger that the Collins class and can carry a significantly greater weapons payload. Neither can carry anywhere near the weaponry of an equivalently sized surface warship but they can carry their weapons much further and for much longer and can strike targets without being detected.
