March 24 (Reuters) – Anduril and Palantir Technologies are working together to develop software for U.S. President Donald Trump’s Golden Dome ​antimissile shield initiative, a source familiar ‌with the matter said on Tuesday.

The $185 billion Golden Dome missile defense project aims to build a space-based shield capable of intercepting ballistic, cruise and hypersonic ‌missiles, ​with hundreds of companies ⁠vying for a role ⁠in developing the shield.

Anduril and Palantir have been interested in being a part of Golden Dome since its inception. Reuters reported ​last year that the firms were working with Elon Musk’s SpaceX on various ⁠parts of the project.

Anduril ⁠was also among companies that were ​awarded half a dozen small Golden Dome contracts ​in November to build competing missile defense ‌prototypes.

Aalyria Technologies, startup Scale AI and software firm Swoop Technologies are also working on the project, the source added.

The companies did ⁠not immediately respond to Reuters requests for comment. The Wall Street Journal first reported the development on ⁠Tuesday.

Lockheed Martin, ‌RTX and Northrop Grumman had ⁠earlier joined the program as ​prime contractors.

The ‌price tag for project has ​increased by $10 ⁠billion to $185 billion in a bid to accelerate key space-based capabilities, the program’s director said last week.
