The U.S. Navy to Facelift Existing Missile Submarine Fleet
The Navy “Boats”
- Ohio (1981 to 1997)
- Virginia (2000 – present)
- Planned – Columbia
The U.S. Navy Ohio class submarines are reaching their age out date. The current 14 Ohio-class ballistic missile submarines have been in service between 1981 and 1997.
The new Columbia class submarine, in conjunction with the existing Virginia class submarine, is meant to take over as the next line of defense for the American Navy.
Congress passed funding for the Virginia submarines in the form of an upgrade called “Virginia Payload Module” or VPM’s, meaning that the Virginia’s Tomahawk strike missile load-out will increase from 12 to 40 by inserting a module increasing the length of the submarine.
This mammoth task is entrusted to the Huntington Ingalls Industries to do the upgrades on the Virginia class submarines and start the new production of the Columbia class submarines. The Columbia class submarines will serve for more than 40 years and will carry hundreds of nuclear warheads to sea at a time and is due to enter service in 2031.
On the 23rd of May, technology and production amalgamated when a steel cutting ceremony took place where the first steel plate was cut with a plasma-burning machine and using an all-digital blueprint to aid in construction.
