Hyman G. Rickover

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.

Keel laying ceremony

The U.S. Navy held a keel laying ceremony for the Virginia-class submarine Pre-Commissioning Unit Hyman G. Rickover (SSN-795) at General Dynamics Electric Boat, May 11.

The initials of the submarine’s sponsor, Darleen Greenert, were welded onto a steel plate that will be permanently affixed to the submarine. She is the wife of former Chief of Naval Operations Admiral Jonathan Greenert (retired).

Admiral Frank Caldwell, Jr., director of the Naval Nuclear Propulsion Program, stated, «Admiral Rickover’s gift to our Nation’s defense – safe, reliable, and militarily superior naval nuclear propulsion – is as vital to our warfighting edge today as it was at the beginning of the Naval Nuclear Propulsion Program 70 years ago. The U.S. Navy and our nation are proud to honor his achievements and legacy with this submarine».

The submarine began construction on September 30, 2015 and is on track to continue the Virginia-class program’s trend of delivering quality submarines within budget and ready for tasking by the fleet.

This will be the second submarine to be named after Admiral Hyman G. Rickover to honor the pioneer of the nuclear navy. The first submarine named for the admiral was the Los Angeles-Class submarine USS Hyman G. Rickover (SSN-709), which served from 1984 to 2006.

Admiral Rickover served for 63 years on active duty service, making him the longest serving member of the U.S. armed forces in history. In the late 1940’s, Admiral Rickover was made director of the Naval Reactors Branch of the Bureau of Ships and he subsequently led the efforts to develop what would become the USS Nautilus, the world’s first nuclear-powered submarine. Admiral Rickover also established and enforced strict safety standards, leading to the U.S. Navy’s safety record of over 162,000,000 miles safely steamed on nuclear power.

Other Virginia-class milestones this year include the commissioning of the USS Indiana (SSN-789) and the combined keel laying and christening of USS Vermont (SSN-792), both currently projected to occur in the fall.

This next-generation attack submarine provides the U.S. Navy with the capabilities required to maintain the nation’s undersea superiority well into the 21st century.
