FOX News/Warrior Maven: Future Navy attack submarine for 2030 - bigger, more lethal, stealthier 

Slated to emerge in the 2030s, a new SSN (X) class of attack submarines may be closer in size to the Navy’s much larger new Columbia-class of nuclear-armed ballistic missile submarines 

The Navy’s future attack submarines for the 2030s will be bigger, faster, more autonomous, networked and stealthier than the existing Virginia-class attack boats because greater size will allow for more advanced quieting technologies to be built into the boats. 

Slated to emerge in the 2030s, a new SSN (X) class of attack submarines may be closer in size to the Navy’s much larger new Columbia-class of nuclear-armed ballistic missile submarines, according to quotes from BWXT CEO Rex Geveden cited in a report from the U.S. Naval Institute. 

The Columbia class is planned to displace about 20,000 tons – whereas the current Virginias displace about 8,000 tons. The Columbia-class hulls are about 42-feet in diameter, while the Virginias are 36-feet wide, the report says.
