![]() ![]() If the SSN-AUKUS fell behind schedule, Australia would have the option of purchasing two additional Virginia-class submarines. On 14 March 2023, the trilateral Australian-British-American security pact known as AUKUS announced that the Royal Australian Navy would purchase three Virginia-class submarines as a stopgap measure between the retirement of their conventionally powered Collins-class submarines and the acquisition of the future SSN-AUKUS class submarines. Virginia-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to operate into the 2070s. They are scheduled to replace older Los Angeles-class submarines, many of which have already been decommissioned. Virginia-class submarines are designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the Virginia class incorporates the latest in stealth, intelligence gathering, and weapons systems. The Virginia class, or the SSN-774 class, is the latest class of nuclear-powered cruise missile fast- attack submarines in service with the United States Navy. 4 × 21" torpedo tubes for Mk-48 torpedoes or UGM-84 Harpoon missiles.12 × VLS tubes (1 × Tomahawk BGM-109 each).25 × torpedoes & missiles (torpedo room) + 12 × missiles (in the VLS tubes).4 × 21" torpedo tubes (for Mk-48 torpedos or UGM-84 Harpoon missiles).12 × VLS tubes (for Tomahawk cruise missiles).Only limited by food and maintenance requirements. Starting in 2029, the Ohio-class submarines will be replaced by the new Columbia-class ballistic missile submarines currently under development.$2.8 billion per unit (2019) $4.3 billion per unit w/VPM (2023) The navy is also considering boosting construction to three submarines a year, which would grow the size of the undersea fleet. fleet is a moving target: each year two more Virginia-class boats roll off production lines and older Los Angeles-class boats are retired. They also carry Tomahawk cruise missiles for land attack missions and are a part of every deployed US carrier battle group to seek out and destroy enemy submarines. These and the Seawolf boats are the real hunter-killers of the fleet, with the mission of stalking and killing enemy submarines and surface ships. The remaining submarines are the 48 Los Angeles- and Virginia-class nuclear attack submarines. Carter was built with a Multi Mission Platform hull insert making it capable of launching and recovering underwater undersea vehicles, SEAL mini-submarines, and who knows what else. One of them, USS Jimmy Carter, is known informally as a spy boat that avoids publicity and is believed to carry out highly classified missions. Designed during the Cold War to go after deep-diving Soviet submarines and operate under polar ice, the Seawolves are large, heavy, highly capable attack boats. The three submarines in the middle are the Seawolf-class attack submarines. Play icon The triangle icon that indicates to play Fourteen Ohios remain on the nuclear deterrence mission, while four Ohios were made redundant by arms control agreements and converted to each carry 154 Tomahawk land attack cruise missiles. Their only job is to take nuclear missiles to sea where they are effectively invulnerable, deterring other countries from launching a surprise attack. Built in the 1980s, the Ohio-class boats are armed with Trident D-5 submarine launched ballistic missiles. The eighteen submarines at the top of the graphic are Ohio-class vessels. submarines are nuclear-powered, their range limited only by onboard supplies of food and other perishable goods. Here's a link to a larger version of the graphic. The graphic depicts the 71 submarines currently on active duty, including Ohio-class ballistic missile submarines, Ohio-class guided missile submarines, and Los Angeles, Sea Wolf, and Virginia-class attack submarines. ![]() naval aviation from 1917 to 2010 and attack submarines of the Mediterranean 2018, shifts its attention to the submarines of the U.S. The excellent website Naval Analyses ( Twitter), producer of visual aids that show U.S. Navy’s undersea fleet is larger than the surface fleet of most countries. This infographic shows the six dozen nuclear-powered underwater titans of the U.S. Navy’s submarine fleet is one of the largest of the world, and certainly the largest and best equipped in the world. ![]()
