AURORA, Colo.—High-ranking American defense executives engaged in redesigning the problematic LGM-35A Sentinel intercontinental ballistic missile initiative now express certainty it will attain functional readiness by the early 2030s.
A test launch for the missile is slated for 2027, and officials anticipate the revamp of the Sentinel program will conclude by the end of this year.
“We’ve undergone a program overhaul that I genuinely believe offers us increased adaptability in deployment. We’ll deliver enhanced capacity more swiftly to the force,” stated Air Force Global Strike Command chief Gen S.L. Davis, who addressed journalists together with U.S. Strategic Command head Navy Adm. Richard Correll and director of critical major weapon systems Air Force Gen. Dale R. White.
The reorganization occurs during a pivotal period for the Pentagon’s nuclear modernization strategy. With the lapse earlier this month of the 2011 New START treaty, there is now an absence of any lawful constraints on Russian and U.S. long-range nuclear armaments.
No fresh American-Russian arms control discussions have been scheduled, and China has hesitated to participate in the prospective negotiations. This has introduced the prospect that the U.S. might choose to expand the magnitude of its deployed nuclear force.
The restructuring of the Sentinel initiative follows its escalating expenditures, which resulted in a so-called Nunn-McCurdy breach in 2024. That mandated the Defense Department to affirm that the Northrop Grumman-made system was vital for national security to continue.
The ICBM program has already lagged behind the original objective of commencing operation in 2029. This implies that some LGM-30 Minuteman III missiles will serve into the 2050s, instead of being retired by 2036, as initially contemplated.
The ground infrastructure for the Sentinel has primarily constituted the root of the difficulties, rather than the missile itself. Under the reorganization, Sentinel will no longer utilize the same silos as the Minuteman III, which are already approximately 60 years old. If those Minuteman III silos were to be renovated under the old plan, they would have been 150 years old at the conclusion of the Sentinel’s estimated operational lifespan of about 70 years.
Alternatively, fresh silos are slated for construction. Officials contend this should be quicker and more economical because the new silos are modular, and the work will not need to be executed on silos that are presently in service.
In total, 450 new silos will be requisite as 400 Minuteman III missiles remain on standby, and there are additional silos. Northrop Grumman is currently constructing a pilot silo in Utah.
“It’s unlocked numerous extra opportunities,” Davis commented. “I don’t believe we have the precise solution for how we’re accomplishing that yet, but we possess greater flexibility.”
The construction of new silos also permits the use of “flexible utilization areas” in some regions. That is, the employment of sites on existing government-owned land, which would lower the expense of obtaining private property.

A Sentinel program office executive, who requested anonymity under stipulations established by the Air Force, indicated that the scope of the public acreage that would be needed was presently being evaluated. Some of the land is at Malmstrom Air Force Base, Mont., one of the three current and future Air Force ICBM installations.
The inaugural Sentinel base will be F.E. Warren Air Force Base, Wyo, and the initiative involves considerably more than merely the silos. In addition to F.E. Warren and Malmstrom, Minot Air Force Base, N.D., is the nation’s other ICBM installation. The Air Force will construct 24 launch centers and three missile wing command centers, distributed across 32,000 square miles in five states and linked by approximately 5,000 miles of fiber-optic cables, officials conveyed.
Sentinel is more substantial than the Minuteman III and is anticipated to possess superior reach and precision, the Air Force and Northrop Grumman affirmed. The missile’s upper casing incorporates a propulsion mechanism absent in Minuteman IIIs.
“This is what provides us with the exact targeting capability that allows us to position the reentry vehicle with pinpoint accuracy, that enhanced precision inherent in the Sentinel system,” a Northrop Grumman official noted.
While Sentinel is being restructured as a program, it may also be modified as a strategic armaments platform. America’s 400 Minuteman III missiles remain on standby with an individual nuclear warhead, though the system is capable of bearing as many as three, a capability which is evaluated utilizing non-nuclear Multiple Independently-targetable Reentry Vehicles. The capacity to deploy MIRVs persists as a mandate.
“We possess the ability to do that,” Correll remarked, addressing the subject generally concerning multiple reentry vehicles. “That’s obviously a determination at the national echelon that would ascend to the president.
The earlier declared intention was to outfit each Sentinel with one warhead. Officials refused to disclose how many warheads a particular Sentinel could transport.
“As STRATCOM commander, I monitor diligently how many missiles are accessible daily,” Correll added. “And I can assure you, our requirements are met, and they will continue to be met.”
