• The Navy is canceling its Constellation-class frigate program.
• Navy Secretary John Phelan said the move would enable the service to build other classes of ships faster.
• The Constellation-class has been facing delivery delays, design problems, and rising costs.

The US Navy is canceling the last four ships of its Constellation-class guided missile frigates in a “strategic shift, the service secretary announced Tuesday.

The frigate program has faced increasing scrutiny over its design issues and the shipbuilding schedule, but the Navy was determined to acquire 20 Constellation frigates, which were crucial to the service’s fleet-size goal.

Navy Secretary John Phelan announced the cancellation in a post on X on Tuesday, saying the last four ships ordered for the program would be terminated.

Work, he said, will continue on the two vessels currently under construction. In his remarks, Phelan said that “while work continues on the first two ships, those ships remain under review as we work through this strategic shift.”

The Constellation frigates were being built by Wisconsin-based Fincantieri Marinette Marine, which won the contract for the new ships in 2020. The $22 billion program for 20 vessels in total has been a topic of criticism from lawmakers, US military leaders, and President Donald Trump.

A Government Accountability Office report pinned delays and cost overruns on the Navy decision to start building the first ship in the class before the design was finished, among other missteps. The Navy also tried to speed up construction by leaning on technologies already proven on other vessels, the watchdog noted in its report last year.

Phelan said that although the Navy was no longer pursuing the program, keeping shipbuilders, a “critical workforce,” employed and the yard ready for future projects was a major concern.

“The Navy needs ships, and we look forward to building them in every shipyard we can,” he said.

Shipbuilder Fincantieri Marinette Marine told Business Insider it believes “that the Navy will honor the agreed framework and channel work in sectors such as amphibious, icebreaking, and special missions into our system of shipyards, while they determine how we can support with new types of small surface combatants, both manned and unmanned, that they want to rapidly field.”

“The key is to maximize the commitment and capabilities our system of shipyards represents,” FMM said.

The Navy is retiring more vessels than it’s building, temporarily driving a lowering of overall fleet numbers at a time when China, the Pentagon’s identified pacing challenge, continues churning out warships at breakneck pace.

The frigate program was key to the service’s vision of a 355-ship fleet. It’s unclear what’s next.

In his post, the Navy secretary said a critical factor in canceling the Constellation was “the need to grow the fleet faster to meet tomorrow’s threats” and that the service’s new framework put new classes of ships on a faster shipbuilding timeline.

The Navy didn’t immediately respond to Business Insider’s request for more information.
