WASHINGTON, April 21 (Reuters) - The Pentagon on Tuesday

unveiled more details of President Donald Trump's $1.5 trillion

defense budget request for fiscal year 2027, by far the largest

year-over-year increase in defense spending in the post-World

War Two era.

In a new wrinkle, the Pentagon has created a category it is

calling "presidential priorities," covering Golden Dome missile

defense, drone dominance, artificial intelligence and data

infrastructure, and the defense industrial base, Pentagon

officials told reporters.

Last year, Trump asked Congress for a national defense budget of

$892.6 billion then added $150 billion through a supplemental

budget request, sending the total price ​tag over $1 trillion

for the first time in history.

On shipbuilding, the budget includes over $65 billion to procure

18 warships and 16 support ships made by General Dynamics ( GD )

and Huntington Ingalls Industries ( HII ) as part of what the

Pentagon is calling the "Golden Fleet" initiative, the largest

shipbuilding request since 1962, the officials said.

The budget ramps up Lockheed Martin F-35 procurement to

85 aircraft per year and includes $102 billion for aircraft

procurement and research and development, a 26% increase over

the prior year, the officials said. Development of

next-generation systems like the Boeing Co F-47 fighter

jet is also a priority, while $6.1 billion is requested for

Northrop Grumman's ( NOC ) B-21 bomber.
