Regardless of what the Defense Department concludes in its Nunn-McCurdy cost breach review of the Sentinel intercontinental ballistic missile program, the U.S. must still have a land-based leg of the nuclear triad, Undersecretary of Defense for Acquisition and Sustainment William A. LaPlante told lawmakers May 15.

The fate of the Sentinel, the successor to the Minuteman III, has been up in the air since January, when the Air Force announced the program had suffered “critical” cost and schedule overruns as defined by the Nunn-McCurdy Act. By law, the Secretary of Defense must certify that the program is essential and that no alternatives exist, or it must be terminated.

Regardless, LaPlante said at a hearing of Senate Appropriations defense subcommittee, an ICBM will be required to meet the National Defense Strategy.
