Pentagon Quietly Replaces Berkowitz as Space Policy Chief, Names Gancio Acting Successor

Breaking Defense reported on October 2 that the Pentagon has quietly replaced Marc Berkowitz as its space policy chief, with his former deputy Michael Gancio now serving as acting assistant secretary for space policy. The change comes the same week the Department of Defense raced to obligate $142 billion from its reconciliation bill before a congressional sequestration deadline, and as the Navy signed a $24.4 billion deal with Raytheon to accelerate SM-6 missile production.

What Happened

According to Breaking Defense, Berkowitz — who was confirmed by the Senate in December and started in the role in January — resigned from the Pentagon's Space Policy office, a position central to coordinating US positions on orbital debris rules, satellite deconfliction, and allied space cooperation. The change was not formally announced, though sources told Breaking Defense he left the position on a Wednesday, and the Defense Department's website was subsequently updated to list Berkowitz as the "former" assistant secretary and Gancio as acting. Gancio, who has a background in intelligence and most recently advised Sen. Tom Cotton on the Senate Select Committee on Intelligence, is now serving in the acting role. Sources told Breaking Defense that Berkowitz had clashed with his boss, Elbridge Colby, on more than one occasion.

The Navy and Raytheon finalized a $24.4 billion contract to accelerate production of the SM-6 interceptor missile, according to Breaking Defense. The five-year agreement, with two additional option years, is intended to "drive faster production, increase manufacturing throughput, and deliver significant cost savings," the Pentagon said, though it did not disclose how many missiles the deal covers.

Separately, Breaking Defense examined a funding arrangement between the National Institutes of Health and the Pentagon, arguing in a companion report that the agreement — signed between the Pentagon's nuclear/CBRN policy office and NIH to accelerate development of medical countermeasures — should be read as using existing statutory acquisition authorities rather than a raid on NIH's budget.

That budget pressure was evident in a separate Breaking Defense report noting the Department of Defense obligated about $142 billion of the reconciliation funding from last year's "One Big Beautiful Bill" ahead of the start of fiscal 2027, according to Breaking Defense. About $10 billion in unobligated reconciliation funds — roughly 7% of the total pot — is now subject to an automatic 8.3% sequestration cut, according to the outlet's estimates, meaning an estimated $830 million in defense buying power has effectively been lost.

Breaking Defense also reported that data centers in Ukraine have faced increased attacks in recent weeks, including strikes on Kyivstar and Vodafone Ukraine infrastructure, citing former deputy defense minister Kateryna Chernohorenko, in a separate dispatch. Ukrainian President Volodymyr Zelenskyy said the country plans to strengthen protection of its data center infrastructure.

Why It Matters

Taken together, these developments show a Pentagon managing several priorities at once this fall. Berkowitz's departure from the Space Policy office, even with Gancio stepping in as acting successor, comes at a time when the United States is trying to shape norms on orbital debris, satellite proximity operations, and allied coordination against rival counterspace programs — areas where reported friction between Berkowitz and Under Secretary Elbridge Colby may have contributed to the exit.

The budget story reinforces a related theme: large sums are moving quickly toward conventional and missile defense priorities, such as the SM-6 deal, even as a portion of reconciliation funds narrowly missed the obligation deadline and were subject to sequestration cuts.

What to Watch

Expect scrutiny over whether Gancio is eventually confirmed in the role or whether another nominee emerges for the Pentagon's top space policy post, and how that affects the pace of international space policy engagement. Watch also for how the roughly $10 billion in reconciliation funds subject to sequestration is treated in upcoming appropriations fights. The SM-6 acceleration deal with Raytheon will be worth tracking for delivery timelines as the Navy looks to rebuild missile stocks. And continued reporting on attacks against Ukrainian data centers will test how critical computing infrastructure is protected as the conflict continues.
