Trump’s Dreams for a Battleship Led to His Navy Secretary’s Ouster

The Navy secretary, John Phelan, was supposed to deliver the first of the president’s ships by 2028. The timeline was nearly impossible.

President Trump wanted one thing, more than anything else, from his secretary of the Navy, John Phelan: a new class of battleships.

“They’ll be the fastest, the biggest and by far — 100 times more powerful than any battleship ever built,” Mr. Trump boasted at a news conference at his Mar-a-Lago estate and resort in Florida a few days before Christmas. Mr. Phelan, a billionaire investor who has a home near the club, stood next to the president as he made the announcement.

Mr. Phelan’s job was to deliver the first of Mr. Trump’s battleships by 2028.

On Wednesday, Mr. Trump fired Mr. Phelan, who had struggled to come up with a plan to deliver the ships on the nearly impossible timeline that Mr. Trump has demanded, senior defense and administration officials said, speaking on the condition of anonymity to discuss sensitive personnel matters.

Mr. Phelan is the first service secretary to be forced from the Defense Department during this administration, though he is far from the only senior Pentagon official to be dismissed. Defense Secretary Pete Hegseth has fired or sidelined more than two dozen generals and admirals over the past year, including the Army’s chief of staff, Gen. Randy George, earlier this month. Mr. Hegseth has also butted heads with the secretary of the Army, Daniel P. Driscoll, over promotions and a host of other issues.

The churn of senior Pentagon officials at a time when the U.S. military is engaged in war with Iran has alarmed top Republican and Democratic members of Congress.

The Pentagon did not respond to questions regarding the circumstances surrounding Mr. Phelan’s dismissal. Mr. Phelan could not immediately be reached for comment.
