Pentagon Aims to Showcase Operational Laser Weapons by Summer 2028

The U.S. Department of Defense is accelerating its efforts to develop and deploy high-energy laser weapons for military use, with a goal of demonstrating operational readiness by the summer of 2028. Undersecretary of Defense for Research and Engineering Emil Michael testified before the Senate Armed Services Committee that significant progress has been made in the scientific development of these weapons, and the focus is now shifting to overcoming engineering challenges to make them mass-producible.

Michael highlighted the Pentagon's commitment to scaling up production through initiatives like President Donald Trump’s "Golden Dome" missile defense system, which relies heavily on directed energy technology. The initiative aims not only to enhance national security but also to reduce costs and improve the scalability of laser weapons for broader military applications. This includes allocating substantial funds towards research and development; the fiscal year 2027 budget request proposes $452 million specifically for Golden Dome, a significant increase from previous years.

The Army and Navy have also committed to spending over $675 million over five years on a Joint Laser Weapon System (JLWS) designed to operate within the broader Golden Dome architecture. These investments reflect an urgent need driven by operational experiences in regions like Iran, which has intensified interest in directed energy systems due to their potential strategic advantages.

However, while scientific advancements have been substantial, challenges remain in ensuring these weapons are reliable and maintainable under real-world conditions. Previous programs, such as the Army’s 50 kW Stryker-mounted Directed Energy Maneuver-Short Range Air Defense (DE M-SHORAD), encountered issues with heat dissipation and overall reliability during operational testing. Addressing these technical hurdles will be crucial for the successful deployment of laser weapons in future conflicts.
