Army to cut generals, PEOs, commands? Service leaders are reportedly weighing a proposal to reduce the number of generals and program executive offices, and even to merge Army Futures Command with Training and Doctrine Command. That’s from Breaking Defense, which says “two sources in industry have seen a document laying the plan out, while another three have heard details that match the document.” Trimming the Army’s top ranks has been on Chief of Staff Gen. Randy George’s mind since he took the top job in 2023. In December, George said the Army would cut at least a dozen general officers in coming years, more than five percent of the service’s 219 authorized GOs. That revelation followed a Dec. 10 oped in Defense One by R.D. Hooker, a former policy director at the Nation Security Council. The Army “is awash in staffs, many of which did not exist during World War II, or even in the 1990s. After 9/11, the Army Staff grew by 60 percent, while headquarters and staffs Army-wide ballooned. All of these headquarters consume resources withheld from the warfighting Army,” Hooker wrote. Developing: SecDef Hegseth wants Navy Vice Adm. Brad Cooper to take charge at Central Command once Gen. Michael “Erik” Kurilla retires some time this summer, according to the Washington Post. Cooper has been CENTCOM’s deputy commander for the past 14 months. If confirmed, his nomination would likely send Army Vice Chief Gen. James Mingus into retirement after his tenure ends in 2026. Mingus was reportedly President Biden’s preference to lead CENTCOM; but Mingus previously served as director of operations for former Joint Chief Army Gen. Mark Milley, who has criticized President Trump, especially after the January 6 failed insurrection at the U.S. Capitol. In the months afterward, Trump suggested Milley should be executed for speaking with a Chinese general during the final weeks of Trump’s first term. “It was not immediately clear why Hegseth favors Cooper over Mingus,” the Post reports, “but the general’s time on the Joint Staff coincided with the chaotic U.S. withdrawal from Afghanistan in August 2021.” Continue reading, here.

How cargo drones could reshape Marine Corps resupply. The Marine Corps is looking for medium-sized cargo drones to handle supply missions across the far-flung islands of the Pacific. But distance isn’t the only challenge the Marines face in the Pacific, Defense One’s Patrick Tucker reports. There’s also component parts, food, fuel and other supplies—the sorts of supply missions where sending human helicopter pilots out is costly and risky, relative to the cargo. It’s also an area other drone companies haven’t been focused on.
On Tuesday, Piasecki Aircraft Corporation announced it had acquired Kaman Air Vehicles’ KARGO program, a medium-lift drone that fits in a standard trailer and can lift a 500-pound payload for long distances, or a 1,000-pound payload for short missions of about 100 nautical miles, said President and CEO John Piasecki.
If Kaman sounds familiar, the firm has been trying to roboticize cargo delivery for the military for more than a decade. It achieved a big first in 2011 with the flight of a remote-controlled heavy lift helicopter, the K-Max, in Afghanistan. Despite the success, the K-Max never became a program of record, as Marine Corps needs changed and the limited autonomy was a problem. Read more, here.
