WASHINGTON, April 2 (Reuters) - U.S. President Donald

Trump is set to unveil a $1.5 trillion defense budget request

for the next fiscal year on Friday, by far the largest

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

War Two era.

Funding for Trump's marquee but controversial $185 billion

"Golden Dome" missile defense shield is expected to be included

in the budget request as well as Lockheed Martin F-35

jets and warships.

Procurement of Virginia-class submarines made by General

Dynamics ( GD ), and Huntington Ingalls Industries ( HII ) as

well as other top shipbuilding priorities is expected.

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.

While the budget request framework for the fiscal year

ending September 30, 2027 is set to be unveiled on Friday, a

Pentagon official said more details on the defense budget will

be announced on April 21.

Earlier this year the administration was contemplating whether

the $1.5 trillion budget request could be in the form of a $900

billion national security budget, with a $400 billion to $600

billion additional request, similar to the structure used in

2026.

The administration plans to use funds for more weapons

production in the hopes of deterring Chinese aggression in the

Indo-Pacific region and to rebuild weapons stocks depleted by

conflicts in Israel, Iran and Ukraine.

The budget request will be debated in Congress in the coming

weeks and months.
