The D Brief: New ‘battleship’ announced; Nigeria, under US surveillance; China’s ICBMs; Boat-strike Qs; And a bit more.

Plans to build a new class of giant surface combatants were announced Monday by President Trump, Defense Secretary Pete Hegseth, and Navy Secretary John Phelan at the president’s Florida mansion. Dubbed “battleships” in defiance of the usual meaning of the term and the “Trump class” in defiance of American tradition, the vessels are to displace some 35,000 tons, three times as much as today’s Arleigh Burke-class destroyers.

Their armament is to include 128 Mk 41 vertical-launch missile tubes, which would be more than the 96 on the Navy’s latest Burkes but less than the 154 on its SSGN guided-missile submarines. 

A fact sheet says the class will also include several weapons that don’t yet exist: a 32-megajoule railgun, two 300kW tactical lasers, and a dozen large tubes for the under-development Conventional Prompt Strike hypersonic missiles. The Associated Press notes that “the Navy has struggled to field some of the technologies Trump says will be aboard the new ship. The Navy spent hundreds of millions of dollars and more than 15 years trying to field a railgun aboard a ship before finally abandoning the effort in 2021.”

Phelan said parts of the ship will be built in all 50 states, hewing to the Navy’s two-century-old practice of spreading contracts to shore up political support. See coverage by the Wall Street Journal and USNI News.

Historian’s note: “The last battleship in history to be built was the HMS Vanguard, completed in 1946; the last battleship commissioned by the U.S. was the USS Missouri, which was decommissioned in the 1990s,” Heather Cox Richardson recounted following the president’s announcement.

Welcome to our final D Brief of 2025, brought to you by Ben Watson and Bradley Peniston. Amid our hectic daily lives, it remains more important than ever to stay informed. So we’d like to take an additional moment to thank you this year for reading. We welcome your tips and feedback here. And if you’re not already subscribed, you can do that here. On this day in 2002, the U.S. military lost its first drone in aerial combat when an MQ-1 Predator was shot down by an Iraqi MiG-25.

Around the Defense Department

The U.S. is now conducting surveillance flights over Nigeria after Trump threatened to send American troops there to halt violence against Christians, Reuters reported Monday. 

The contracted flights have been taking place since late November, just weeks after Trump issued the threat, and they typically depart from Ghana before returning, according to flight tracking data. An expert from AEI told Reuters “the operation appeared to be running out of an airport in Accra, a known hub for the U.S. military’s logistics network in Africa.” Pentagon officials declined to discuss the surveillance flights.

Following Monday’s new row between the White House and Denmark, the State Department approved a $951 million sale of 230+ AMRAAM-ER missiles to Copenhagen, the Pentagon’s Defense Security Cooperation Agency announced.
