What will replace the Ohio class?
Columbia class
Eventually, all Ohio-class SSBNs will be replaced by the Columbia class. The four SSGNs, meanwhile, will be replaced by the Virginia-class nuclear attack submarine, which will have vertical-launch systems capable of firing 12 to 40 Tomahawks or Harpoon anti-ship missiles.
Is Columbia class bigger than Ohio?
The Columbia class will take over the role of submarine presence in the United States’ strategic nuclear force. The submarines will be 560 feet (170.7 m) long and 43 feet (13.1 m) in diameter, as long as the Ohio-class design, and 1 foot (30 cm) larger in diameter.
What is the newest class of US submarine?
Virginia Block V
When it comes to submarine power, the U.S. Navy’s latest submarine is the Virginia Block V, and on the other side of the Atlantic is Russia’s Yasen-M class. The American submarine can carry more weapons, but the Russian sub can carry more missiles…and hypersonic weapons, according to Naval News.

Where are Columbia-class submarines built?
The supermodules will then be transported by barge to the company’s Final Test and Assembly facility in Groton, Connecticut, where the components will be assembled into a complete submarine in a facility now under construction specifically for the Columbia class.
Where are the Ohio class submarines built?
The Ohio-class submarines were constructed from sections of hull, with each four-deck section being 42 ft (13 m) in diameter. The sections were produced at the General Dynamics Electric Boat facility, Quonset Point, Rhode Island, and then assembled at its shipyard at Groton, Connecticut.
When will the Columbia-class ballistic missile submarine be operational?
Columbia-class ballistic missile submarines (SSBNs) are being constructed by General Dynamic subsidiary Electric Boat for the US Navy in collaboration with Newport News Shipbuilding. The first Columbia-class submarines will be operational with the US Navy in 2027.
What is replacing the Ohio-class submarine?
Starting in 2031, the Navy plans to replace each retiring Ohio-class boat with a new Columbia-class SSBN submarine. The Navy has identified the Columbia-class program as its top priority program, and wants to procure the first Columbia-class boat in 2021.
The Navy is only building 12 Columbia-Class submarines to replace 14 existing Ohio-class nuclear-armed boats because the new submarines are being built with an improved nuclear core reactor that will better sustain the submarines, Navy officials have said.
