Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets

General Atomics, the company that builds the electromagnetic aircraft launch system for the Ford-class carriers, said Trump’s decision to revert to steam “warrants careful reconsideration”. The company told the Journal its work on the new ship is nearly 50% complete and “changing course now would introduce significant cost, schedule, and integration risks”.

Senator Mark Kelly, an Arizona Democrat and a former astronaut, was more blunt in his reaction to the news.

“I’ve launched off the front of aircraft carriers hundreds of times, have a Master’s degree in aeronautical engineering, and am a test pilot and even I wouldn’t suggest to the Navy how to engineer specific systems on its ships,” Kelly wrote on social media. “Donald Trump should stick to what he knows best – ballrooms, bankruptcy, and bullshit.”
