President Donald Trump unveiled a new "Trump class" of Navy battleships Monday, describing them as a superior war fighting vessel to replace an "old and tired and obsolete" US fleet.

"They'll help maintain American military supremacy, revive the American ship building industry, and inspire fear in America's enemies all over the world," Trump said in revealing the new category of vessel from the library at Mar-a-Lago.

Flanked by renderings of the "Trump class" battleships at sea, Trump said he would take an active role in their design. The president made the announcement Monday afternoon in Florida with Defense Secretary Pete Hegseth and Secretary of State Marco Rubio, who is also national security adviser.

The "Trump class" ships will form part of the new "Golden Fleet" that the president has ordered up for the Navy, meant to better counter China and other adversaries and to more closely adhere to Trump's aesthetic standard.
