The Ohio-class submarine is currently America's largest submarine. The Navy has purchased nine of these submarines at a cost of $22 billion. There is also an option to purchase another. Block V submarines will be longer and more powerful than their predecessors. They would be the US's second-largest submarine if built to specification.
Ohio-class submarines
The US Navy's Ohio Class submarines are the largest US military ships. They are powered using steam turbines as well as pressurized water generators. They can travel at 25 miles per hour and can reach a depth 800 feet. Electric Boat of Groton, Connecticut constructed the Ohio's hull.
The Ohio-class submarines can carry up to 154 Tomahawk cruise missiles. Each Tomahawk missile has a range of 1,000 miles. They are also equipped with up to 66 special operations personnel. The forward-most missile tubes can be converted to lock-out chambers.
Typhoon-class submarines
The US Navy is ending its Typhoon-class submarines. These were made to counter Soviet submarines during Cold War. The US built the Typhoon Class to match its nuclear-powered submarines. The overhaul of the lead submarine, TK-208 is underway. It is unlikely it will be returned to service. Additionally, all other submarines of the class are scheduled to be decommissioned.
The Typhoon submarine has a multi-hull design that is unique. It features two pressure hulls as well as five inner habitable. There are 19 compartments. The missile compartment can be found in the bow, just above the two pressure-hulls. The outer light-hull is made of steel and the submarine's submarine structure is made up of titanium.
Russian submarines
The Russian Navy currently has four submarines (the Borei class) in its fleet. Each submarine has a crew size of 107. They are about a hundred and seventy meters long, thirteen meters wide, and weigh 24,000 tonnes. They are powered by nuclear reactors. Their advanced hulls reduce noise. They can travel at speeds of up 25 knots underwater.
Russia's first submarine, the Belgorod 1, is being constructed. It will carry Poseidon missiles, which can be fired at coastal targets. While the Belgorod is not the largest submarine built, other countries will build larger ones.
Block V submarines
Block V submarines are considerably larger than older versions. Their length ranges from 377 feet up to 460ft. These submarines, which can carry 10 thousand tons, are second only to the Ohio Class in size. Each submarine can deploy up 40 cruise missiles and has eighty three feet of vertical rocket system (VLS).
Block V submarines will also receive acoustic superiority enhancements. These upgrades have been a top priority for the Navy when designing new submarines. The new boats will have roughly a 20 percent difference in design from Block IV boats, according to a report by the Congressional Research Service in February 2022.
