Troy Meink, President Donald Trump’s nominee to be Air Force Secretary, endorsed nuclear modernization at his confirmation hearing March 27.
“Upon confirmation, I intend to conduct a comprehensive review of the Department of the Air Force’s existing nuclear weapon systems and modernization initiatives to identify the best ways to maintain a safe, secure, and effective nuclear deterrent, which is essential for our national security,” Meink said in written testimony provided to the Senate Armed Services Committee.
Meink committed to producing the Air Force’s new Sentinel intercontinental ballistic missile, which is over budget and behind schedule. Sentinel’s cost and schedule lapses exceeded statutory limits, triggering a so-called Nunn-McCurdy breach and mandatory review. While the Pentagon declared the program critical to national security in July 2024, allowing it to continue, costs continue to climb and now are estimated at nearly $141 billion. Air Force officials are working to restructure the program, having instituted a pause on design and construction of launch facilities pending further study.
Sentinel’s schedule is now approaching the September 2030 “no-fail” date set by U.S. Strategic Command as its estimated target to transition from Minuteman III ICBM to Sentinel.
“The ground leg of the nuclear triad—Minuteman III and, over time, Sentinel—are foundational to strategic deterrence and defense of the homeland,” Meink’s written testimony states.

Asked by Sen. Deb Fischer (R-Neb.) if he would commit to “utilizing all available tools to accelerate Sentinel,” Meink said he would—but after “diving into the results of the Nunn-McCurdy [breach].”
Meink’s written testimony said he wants to find “ways in which the program may be able to regain schedule and reduce cost. Ultimately, the success of this program will be a coordinated effort among the whole of government, … industry, and our civil communities, all working together to complete the most massive national-defense modernization effort in this century.”
Air Force officials have said many of Sentinel’s problems stem not from the missile itself but from the extensive civil engineering and military construction costs involved with updating infrastructure built decades ago. Meink said his review would focus on making sure programs have enough funding, not cutting anything back.
“One of the first things I plan to do is take a holistic look at all the modernization and all the readiness bills that we have coming, and then I will put together and advocate for what resources I think are necessary to execute all of those missions, … working both within the administration and with Congress,” Meink said.
Meink shared the witness stand and confirmation hearing with Michael P. Duffey, nominated to be undersecretary of Defense for acquisition and sustainment, who also endorsed complete nuclear modernization.
“Nuclear modernization is the backbone of our of our strategic deterrent, and ensuring that we have a modern, capable nuclear enterprise that not only includes the B 21 which is a successful acquisition program by all accounts, but the Columbia class submarine and the Sentinel nuclear ICBM, are critical,” Duffey told Fischer.
