We assess that directed energy's long demonstration era ends within the next budget cycle, and that the discriminating event is a contract line — production quantities, spares, training, and a program office holding multi-year money — rather than any test result. The Leonidas class of high-power microwave systems and the 50-kilowatt class of lasers now hold the field data such a decision requires, and the cost-exchange crisis in air defense has made the status quo untenable. A real contract re-sorts the whole defeat-layer market: capital flows, integration seats in the command backbone, and export posture all follow the first buyer. The desk weights the microwave track as likelier to cross first, on magazine-depth economics against massed raids.
Directed energy has won more demonstrations than any weapon class in history that has never been bought properly. For two decades, high-power microwave and laser systems have defeated drone targets at test ranges on several continents, and the footage has been impressive every time. What has not happened is the transition that separates a science project from a weapon: a funded program of record, with production quantities, a spares chain, a training base, and a program office holding a multi-year budget line. The desk's assessment, stated plainly and with the caveats such statements require, is that the transition arrives in the 2027 budget cycle. The evidence is the accumulation of field data, the maturation of two distinct technology tracks, and a cost-exchange problem that has made the status quo untenable. The discriminating event to watch for is a contract, and everything in this piece follows from what a contract changes.
The microwave track is the likelier to cross first, on magazine economics. Epirus's Leonidas family — delivered to the Army under the Indirect Fire Protection Capability microwave effort, tested against raid scenarios, and now offered in fixed, podded, and vehicle-mounted forms — projects an effect over a volume rather than at a point, which is the only physics that answers a saturation raid's arithmetic. Its magazine is generator fuel; its engagement cost is near zero; its limit is the safety and fratricide geometry of radiating high-power electromagnetic energy near friendly electronics, aviation, and people. CHIMERA, the Air Force's extended-range air-base microwave defense, pursues the same effect at longer reach for the fixed-site raid problem. The services now hold field data on reliability, availability, and safety envelopes — precisely the corpus a program-of-record decision requires.
The laser track approaches the same threshold from a different direction. The 50-kilowatt class — the Army's Stryker-mounted prototypes, the Paladin-based demonstrator, the Navy's HELIOS installation on a deployed destroyer, Britain's DragonFire — has accumulated the honest lessons that prototypes exist to produce: power and thermal management dominate availability, weather and aerosols tax the beam, dwell time per target bounds the salvo size, and field maintenance of precision optics is a discipline unto itself. Israel's Iron Beam, moving from development into operational delivery, is the first national program to complete the crossing and therefore the one every other procurement office is studying. The 50-kilowatt class answers the raid's precision problem — near-zero marginal cost per shot, a deep magazine, surgical effect — at the price of engaging one target at a time. That profile complements the microwave's area effect.

Microwave and laser counter-drone systems have won every demonstration for years. The 2027 budget cycle should bring the first funded program of record — and a re-sorting of the defeat layer.
