U.S. Navy takes delivery of advanced attack submarine USS Iowa

The USS Iowa is the 24th Virginia-class submarine (VCS) to be built under the collaboration of General Dynamics Electric Boat (GDEB) and HII-Newport News Shipbuilding. It also becomes the 13th attack submarine delivered by GDEB, exemplifying the enduring partnership between the shipbuilders.

This delivery signifies the transfer of the submarine from its builders to the Navy, moving it closer to operational status. The vessel and its crew will now begin trials and testing in preparation for its commissioning and integration into the active fleet.

“The Virginia-class submarine represents a Navy and industry commitment to deliver warfighting excellence to the fleet,” said Captain Mike Hollenbach, Virginia Class Submarine programme manager. “Iowa is the second Virginia-class submarine delivered this year. With each delivery, the Navy continues to strengthen our Nation’s undersea advantage.”

Designed for modern warfare, Virginia-class fast-attack submarines provide enhanced stealth, surveillance, and special warfare capabilities. They are a critical component of the Navy’s ability to maintain undersea dominance in the 21st century.

The USS Iowa is the sixth of 10 Block IV Virginia-class submarines, specifically configured to enhance readiness and reduce maintenance. According to NAVSEA, these submarines are vital to ensuring sustained readiness for high-end combat operations.

SSN 797 is the fifth U.S. Navy vessel, and the first submarine, named after the state of Iowa. Its predecessors include the USS Iowa (BB 61), a decorated battleship that served in World War II and later conflicts such as the Korean and Vietnam Wars.

The submarine was christened on 17 June 2023 at the GDEB shipyard in Groton, Connecticut, by its sponsor, Ms. Christie Vilsack. The commissioning ceremony is scheduled to take place on 5 April 2025 in Groton, marking its official induction into the fleet.
