The Navy has completed a plan to replace the electromagnetic aircraft launch system and advanced weapons elevators on USS Doris Miller (CVN-81) with legacy steam and hydraulic systems following a Trump administration directive. The plan was submitted to the White House Office of Management and Budget for presidential review.

What's happening

  • Navy finished detailed plan replacing EMALS and advanced weapons elevators on CVN-81 Doris Miller with legacy steam and hydraulic systems per Trump's August 13 national security memorandum.
  • Plan delivered to White House Office of Management and Budget for presidential submission and decision.

Why it matters

  • EMALS and advanced weapons elevators represent core modernization of Gerald Ford-class design; reverting to steam systems signals potential major redesign affecting production schedule and supply chain.
  • Plan implementation would require supplier coordination for legacy system components and revalidation of carrier integration and testing protocols.

Going deeper

  • CVN-81 Doris Miller is newest Gerald Ford-class carrier in production; design substitutions at this stage typically cascade across remaining units in the class.

The intrigue

  • Replacing unproven EMALS technology with proven steam catapults trades operational confidence for modernization goals, raising questions about long-term carrier fleet capability standards.

The fine print

  • Plan remains under White House review; no final decision or implementation timeline disclosed.
  • Terms and scope of system replacement undisclosed; full cost impact and production schedule effects unknown.
