President Donald Trump has ordered a major overhaul of U.S. Navy shipbuilding, including a return to traditional steam-powered aircraft catapults on future aircraft carriers.

The decision targets the electromagnetic aircraft launch system used on the Gerald R. Ford-class carriers. Trump has criticised the technology as expensive and complex, while supporters argue that electromagnetic systems offer important advantages in aircraft operations and maintenance.

The order also opens the door for foreign shipbuilders to participate more directly in U.S. military shipbuilding, under conditions requiring investment in American shipyards, workforce expansion, technology transfer and U.S.-based supply chains.

The move comes as Washington faces growing concerns over China's rapidly expanding naval shipbuilding capacity. China currently operates three aircraft carriers, while its latest carrier, Fujian, also uses electromagnetic launch technology

The American President Donald Trump has ordered the US Navy to abandon electromagnetic catapults on future Gerald R Ford-class aircraft carriers and return to the steam-powered systems used on older Nimitz-class carriers.&nbsp;According to The Wall Street Journal, Trump signed a national security memorandum directing the Navy to remove the electromagnetic aircraft launch system, or EMALS, from the fourth Ford-class carrier, the future USS Doris Miller, and all subsequent ships in the class. The first three Ford-class carriers will retain the electromagnetic system.&nbsp;Also read: <a href="https://www.wionews.com/world/what-is-loss-of-separation-inside-the-aviation-term-linked-to-trump-s-marine-one-1785992154201">What is ‘Loss of Separation’? Inside the aviation term linked to Trump’s Marine One</a>&nbsp;Trump has repeatedly criticised EMALS, arguing that it is too complex and less reliable than steam technology. He has pushed for a return to steam catapults since his first presidential term, after hearing a sailor praise the older system during a visit to a US Navy ship.
