The twin efforts to upgrade the Air Force\u2019s legs of the nuclear triad \u2014 both of which are run by Northrop Grumman \u2014 are programs that \u201ccannot fail,\u201d he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kendall declined to go into detail about the problems facing Sentinel, citing his recusal from making decisions on the program. Kendall stepped back from the Sentinel and B-21 programs when he became secretary due to his previous consulting work with Northrop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But the vast scope of the Sentinel program \u2014 which includes real estate development; civil engineering; the creation of both communications and command-and-control infrastructure; and the production of the missile itself \u2014 has proved challenging, he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cSentinel is one of the most large, complex programs I\u2019ve ever seen,\u201d Kendall said. \u201cIt\u2019s probably the biggest thing, in some ways, that the Air Force has ever taken on.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Air Force awarded Northrop a $13.3 billion contract in 2020 to develop the Sentinel program \u2014 then referred to as the Ground Based Strategic Deterrent, or GBSD \u2014 to succeed the LGM-30G Minuteman III, which first deployed a half-century earlier. Sentinel is expected to cost roughly $100 billion in total.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But in the early stages of the program, Kendall said, there was a great deal of uncertainty, particularly on costs. Part of that uncertainty stemmed from the multiple decades that had elapsed since the Minuteman was created.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kendall said \u201cunknown unknowns\u201d are surfacing that the department will have to work through, including factors related to command-and-control infrastructure, such as the complexes that missileers would use to launch the Sentinel.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kendall said some costs may rise in the process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAs we get more into the program, as we understand more deeply what we\u2019re actually going to have to do, we\u2019re finding some things that are going to cost money,\u201d Kendall said. \u201cWe\u2019re trying to assess how much of an impact that\u2019s going to have and what kind of adjustments we\u2019re going to have to make because of it.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Government Accountability Office released a weapons assessment report in June outlining problems with Sentinel that would cause its rollout to slip from 2029 to sometime between April and June 2030.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">GAO highlighted lingering staffing shortfalls, supply chain issues and software challenges.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Minuteman III program that Sentinel will succeed includes 400 missiles in 450 silos across nearly 32,000 square miles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Kendall added he is \u201ccautiously optimistic\u201d about the B-21 program. The first Raider carried out its long-awaited first flight on Nov. 10, and Kendall said it has \u201cgot a ways to go on the flight testing.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The B-21 experienced \u201cminor slips internally,\u201d Kendall said, but has for the most part followed the plan he and William LaPlante, now undersecretary of defense for acquisition and sustainment, put together during their previous tenures in the Pentagon during the Obama administration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the time, Kendall was undersecretary of defense for acquisition, technology and logistics, and LaPlante served as assistant secretary of the Air Force for acquisition, technology and logistics.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It has been
