Just Not Replaceable? The U.S. Navy is extending the service life of its aging Nimitz-class aircraft carriers due to delays in commissioning new Ford-class carriers. The Nimitz-class vessels, first introduced in 1975 with a planned 50-year service life, are approaching or surpassing this threshold. Only one Ford-class carrier, the USS Gerald R. Ford, has been commissioned, with further delays affecting subsequent ships like the USS Enterprise.
-Efforts to retrofit and extend the Nimitz-class carriers have encountered significant challenges, including extensive delays in overhauls due to damage to steam turbines on ships like the USS George Washington and USS John C. Stennis.
-These setbacks have complicated the Navy's ability to deploy carriers and have adversely affected the quality of life for sailors aboard, with reports of extremely tough living conditions leading to several suicides among crew members.
The U.S. Navy has been forced to rely on their Nimitz-class aircraft carriers for longer than expected. The Nimnitz-class, which first debuted in 1975, has a fifty-year service life. For the namesake vessel, the first-off-the-line USS Nimitz, that fifty-year threshold is fast approaching. The remaining Nimitz carriers were rolled out over thirty-five years, and now many more are also approaching their fifty-year thresholds.
Yet, the Navy has been slow to produce the Nimitz’s replacement, the Ford-class. To date, only one Ford-class, the USS Gerald R. Ford, has been commissioned, while a second is on the way. To maintain current fleet levels, eleven active aircraft carriers, the U.S. Navy is working to extend the lifespans of their Nimitz-class carriers.
The process has not gone smoothly.
The Pentagon is committed to maintaining current levels for their carrier fleet. One could argue that the U.S. Navy does not need eleven supercarriers. Restraint advocate Barry Posen argues that seven to nine supercarriers would probably be sufficient to address all of America’s national security concerns. But the Pentagon feels otherwise, obviously, flare-ups in the Middle East, and rising tension throughout the Indo-Pacific, no doubt partially inspiring the commitment to maintaining current fleet levels. Delays to the Ford-class are no doubt another reason.
The forthcoming USS Enterprise, the third Ford-class carrier, will be delayed eighteen months.
“Extending Nimitz, extending Ike, it’s going to happen for every Nimitz-class carrier. At least one extension,” Vice Admiral Kenneth Whitesell said last year.
Yet the Nimitz extensions have not gone smoothly. Delays in the retrofitting process have been common.
“Extensive delays to the mid-life refueling and complex overhauls of two nuclear-powered aircraft carriers were due to damage to the steam turbines that power the ship,” the U.S. Naval Institute (USNI) reported. The two carriers in question were the USS George Washington and the USS John C. Stennis. Each carrier was supposed to undergo a four-year overhaul. But the Washington needed nearly six years; the Stennis will need five and a half.
“The change in redelivery schedule for [Stennis] is primarily a reflection of growth work discovered after the ship arrived at Newport News Shipbuilding (NNS) and subsequent challenges within the supply base,” Huntington Ingall’s Industries (HII) NNS said in a statement. “We are applying lessons learned from both George Washington and John C. Stennis to what we are doing to prepare USS Harry S. Truman (CVN-75) for refeuling and complex overhaul”
The delays have complicated the Navy’s ability to deploy carriers, and have also degraded the quality of life for the sailors aboard the vessels being retrofitted; a 2023 Navy investigation found that sailors aboard the George Washington, “endured some of the toughest living conditions of any members in the military.” Several of Washington’s sailors committed suicide.
