Trump's "Golden Dome" plan faces uncertainty. The mass production of candidate systems has been delayed.

The U.S. Army has postponed until next year the decision on whether to approve full production of Lockheed Martin's $2 billion air defense radar system, which is considered a candidate for the "Sky Screen" defense umbrella proposed by the Trump administration. The U.S. Army had previously stated that it planned to make a full-speed production decision on Lockheed's "Sentinel A4" radar in October, but now the timeline has been delayed to between July and September 2026 for more rigorous battle testing. The significance of the previous delay is significant because the full-speed production phase is an important milestone for defense contractors and is also the most profitable stage in weapon programs.
