The U.S. Navy christened one of its newest Virginia-class attack submarines, the future USS Hyman G. Rickover (SSN-795), during a 9 a.m. EDT ceremony Saturday, July 31, 2021, at General Dynamics/Electric Boat, in Groton, Connecticut.

The principal speaker was Admiral James Caldwell, director, Naval Nuclear Propulsion Program, Department of the Navy/Department of Energy. Mr. James Geurts, performing the duties of Under Secretary of the U.S. Navy, also delivered remarks. In a time-honored Navy tradition, the submarine’s sponsor, Mrs. Darleen Greenert, christened the ship by breaking a bottle of sparkling wine across the bow.

«The future USS Hyman G. Rickover (SSN-795) will play an important role in defending our nation during this time of strategic competition», said Caldwell. «It stands as proof of what teamwork – from civilian to contractor to military – can accomplish. I am confident USS Hyman G. Rickover (SSN-795) and its crew will proudly serve our country’s interest for decades to come, ensuring America remains strong».

The future USS Hyman G. Rickover (SSN-795) is the second nuclear-powered fast attack submarine in recognition of Admiral Rickover. The first USS Hyman G. Rickover (SSN-709) was commissioned at Submarine Base, New London, in Groton, on July 21, 1984. SSN-709 and its crew deployed 12 times until its decommissioning in December 2007. Over the years, its decorations included the Atlantic Fleet Golden Anchor Award, Submarine Squadron Eight’s anti-submarine warfare white «A» and engineering red «E» awards and the prestigious Sixth Fleet «Hook ‘Em» award for anti-submarine warfare excellence.

Rickover, known as the «Father of the Nuclear Navy», served in the U.S. Navy for 63 years on active duty. His views touched matters of design, propulsion, education, personnel and professional standards. His team of engineers designed and constructed the first nuclear-powered submarine, USS Nautilus (SSN-571). This accomplishment led to the world’s preeminent fleet of nuclear-powered submarines and aircraft carriers.

Virginia-class submarines are built to operate in the world’s littoral and deep waters while conducting anti-submarine warfare; anti-surface ship warfare; strike warfare; special operations forces support; intelligence, surveillance, and reconnaissance; irregular warfare; and mine warfare missions. Their inherent stealth, endurance, mobility, and firepower directly enable them to support five of the six maritime strategy core capabilities – sea control, power projection, forward presence, maritime security and deterrence. They are replacing Los Angeles-class submarines as they retire.
