The Pentagon is doubling down on laser weapons research

While this budget release only offers a high-level view of the U.S. military’s spending priorities, a preliminary analysis indicates the Pentagon wants to pour more than 2 billion into research, development, testing, and evaluation (RDTE) programs involving high-energy laser weapons and other directed energy systems in fiscal year 2027. This funding, if approved, would not just mark a major increase over the more than 1 billion in annual expenditures on directed energy RDTE over the last five years, but also significantly outpace the Pentagon’s average yearly spending on such efforts under the Strategic Defense Initiative (also known as “Star Wars”) across the entire life of that program. This might just be the most significant U.S. military investment in directed energy weapons research, well, ever. Below, you’ll find some high-level insights on proposed directed energy weapon spending culled from the Pentagon’s fiscal year 2027 budget request. No Significant Directed Energy Procurement (Yet) Despite the Pentagon’ stated goal of fielding laser weapons at scale within the next three years, the procurement section of the department’s fiscal year 2027 budget request does not currently detail any major purchases to that end. The sole procurement line item explicitly for directed energy—‘Directed Energy Systems’,’ which covers the U.S. Navy’s low-power AN/SEQ-4 Optical Dazzling Interdictor, Navy (ODIN) laser weapons, according to previous budget documents—is completely zeroed out, down from the 3 million requested in fiscal year 2026 to support the eight ODIN systems already installed across the service’s Arleigh Burke-class guided-missile destroyer fleet.That said, the procurement documents do contain two ‘Counter-Small Unmanned Aircraft Systems (C-sUAS)’ program elements that could encompass directed energy procurement efforts. The first program element is a defense-wide item under ‘Major Equipment, TJS [The Joint Staff]’ that includes an 800 million request (up from 732 million authorized last year), which is likely for the Pentagon’s new Joint Interagency Task Force 401 (JIATF 401) established last year, according to the corresponding fiscal year 2027 budget documents for RDTE. The second program element, however, is a U.S. Army item that includes a 994.1 million request (up from 693.4 million authorized last year) and previously involved the Enduring High Energy Laser (E-HEL) system, 24 of which the service plans to “produce and rapidly field” in the coming years as its first official directed energy program of record. Given that E-HEL units cost nearly 25 million apiece, according the Pentagon’s fiscal year 2026 budget request, the boost in the Army’s C-sUAS line item could potentially cover the procurement of additional systems. Unfortunately, we won’t know for sure until the full justification books are released later in April. Defense-Wide Laser Weapon RDTE Increases, With Room to Grow Defense-wide laser weapon RDTE efforts overseen by the Office of the Secretary of Defense (OSD) saw significant increases in the Pentagon’s fiscal year 2027 budget request, to 44.5 million requested under the ‘High Energy Laser Advanced Component Development Prototype’ program element (up from 5.5 million in fiscal year 2026) and 201 million requested under the ‘High Energy Laser Advanced Technology Program’ (up from 120 million). Managed by the Pentagon’s Joint Directed Energy Transition Office (JDETO), these program elements are focused on accelerating the maturation of directed energy systems like laser weapons to “enable the demonstration of military utility for mission areas” across the U.S. military, according to the department’s fiscal year 2026 budget request. The High Energy Laser Advanced Technology Program in particular includes the Joint Laser Weapon System (JLWS), a collaboration between the Army and Navy to designed to counter cruise missile threats as part of the President Donald Trump’s ‘Golden Dome for America’ missile defense shield. (It also likely includes the Pulsed High Energy Laser Scaling Initiative, a new start in fiscal year 2026 designed to explore the potential applications of pulsed laser weapons.) There’s also the question of the Pentagon’s 580 million in RDTE funding for JIATF 401 detailed in its fiscal year 2027 budget request. While the organization is certainly interested in directed energy weapons given their potential counter-drone applications, it’s unclear from the budget documents how much of that funding will apply to such initiatives given the its expansive remit. A Major RDTE Boost for Golden Dome Directed Energy Efforts The Pentagon’s fiscal year 2027 budget request contains 452 million in proposed RDTE spending for the “development, integration, and assessment” of directed energy weapons in support of Golden Dome, more than triple the 142 million enacted under the ‘One Big Beautiful Bill Act’ reconciliation package that Trump signed into law in July 2025. Like last year’s funding, this particular program element is also reliant on a reconciliation package separate from the Pentagon’s base budget request. It’s worth pointing out that this spending increase is marked as procurement, even though it’s featured in the RDTE documentation of the Pentagon’s budget request. This is likely because this proposed funding will focus on purchasing technology to develop and test prototypes or prove a concept, while the separate procurement budget title will go to acquiring systems for active fielding. U.S. Army Laser Weapon RDTE Is Unclear With the cancellation of the 50 kilowatt Directed Energy Maneuver-Short Range Air Defense (DE M-SHORAD) and 300 kw Indirect Fire Protection Capability-High Energy Laser (IFPC-HEL) efforts, the Army now has three publicly-known laser weapons initiatives in the works: E-HEL, JLWS, and the Army Multi-Purpose High Energy Laser (AMP-HEL) that’s already actively shooting down drones (at home, at least). Unfortunately, the fates of these projects appear ambiguous at the moment, mostly due to the structure of the Pentagon’s budget request. Apart from defense-wide programs, the budget documents only contains program elements that explicitly cover laser weapons or directed energy systems for the Navy and U.S. Air Force, but not for the Army. Indeed, AMP-HEL and E-HEL fall under the Army’s Maneuver – Short Range Air Defense (M-SHORAD) item, while JLWS work falls under the Expanded Mission Area Missile (EMAM) program. And while both of those larger programs are poised for significant spending increases in fiscal year 2027—460 million requested for M-SHORAD (up from 296 million) and 235 million requested for EMAM (up from 63 million)—how those funds will trickle down to their subordinate directed energy projects remains to be seen. U.S. Navy Laser Weapon RDTE Expands When senior Navy leaders declared that “the dream of a laser on every ship can become a real one” at the beginning of the year, they were absolutely not kidding. The service’s fiscal year 2027 budget request includes a significant increase in funding under its ‘Directed Energy and Electric Weapon Systems’ program element, with the service asking for more than 94 million in RDTE spending, up from 14.5 million in fiscal year 2026. Without the justification books, the applications of this funding are also unclear. The service has no stated plans to procure more ODIN systems, or additional 60 kw High Energy Laser with Integrated Optical Dazzler and Surveillance (HELIOS) weapons beyond the lone system installed aboard the destroyer USS Preble, according to last year’s budget request. In addition, the service’s 300 kw High Energy Laser Counter [Anti-Ship Cruise Missile] Project (HELCAP) was officially slated for completion in fiscal year 2026, the budget documents say. This leaves a few potential options to consider: the Navy’s funding boost is likely focused on either jumpstarting HELIOS development, advancing the Office of Naval Research’s 400 kw “SONGBOW’ initiative, or something related the unidentified (and potentially new) laser weapon the service reportedly tested in the Red Sea last year. We’ll have to wait for the release of this year’s justification books to find out. U.S. Air Force Laser Weapon RDTE Shrinks, But Not By Much Despite plans to pursue yet another airborne laser weapon and revisit ground-based laser systems to protect airbases and other installations, the Air Force’s budget request actually indicates a small decrease in RDTE funding for under its ‘Directed Energy Technology’ program element, which fell from 96 million requested in fiscal year 2026 to just under 92 million requested for fiscal year 2027. The service’s other directed energy program element, ‘Directed Energy Prototyping,’ remained zeroed out after falling from 1.31 million in fiscal year 2025 to zero in fiscal year 2026. The Pentagon’s skinny fiscal year 2027 budget request suggests a familiar pattern for directed energy weapons: sustained (and in many cases accelerating) investment in RDTE, but no definitive signals that the technology is ready to transition into procurement and fielding at scale just yet. Despite years of promises that these systems are nearing operational relevance, the funding profile still points to a force that is continuing to experiment, refine, and prototype rather than putting them in the hands of U.S. service members in the immediate term. Of course, that picture could shift once the full budget justification books are released later this month. But for now, the future of directed energy research and development appears brighter than ever.
