The Navy intends to deploy its conventional prompt strike hypersonic weapon on Virginia-class attack submarines, after previous discussions of putting the weapon on the larger Ohio-class guided-missile submarine (SSGN), according to budget request documents.

In its Fiscal Year 2021 budget overview, the Navy outlines a research and development portfolio with 5 percent more funding than this current year – for a total of $21.5 billion – that is aimed at “providing innovative capabilities in shipbuilding (Columbia class), aviation (F-35), weapons (Maritime Strike Tomahawk), hypersonics (Conventional Prompt Strike), unmanned, family of lasers, digital warfare, applied [artificial intelligence], and [U.S. Marine Corps] expeditionary equipment. These technologies are crucial to maintaining DON’s competitive advantage.”

On the Conventional Prompt Strike, the Navy wants to invest $1 billion for research and development.
