LONDON — Solid rocket motor manufacturer X-Bow Systems is launching what the company hopes will be a much-needed remedy to the ongoing conundrum of combating cheap drones with multimillion-dollar interceptors.

The New Mexico-based firm this week pulled the curtain back on Buckler, an interceptor designed to kill Group 3 drones — UAS weighing up to 1,320 pounds and flying below 18,000 feet at under 250 knots — for a cost of under $100,000 per unit.

Buckler is designed to knock out UAS at supersonic speeds, according to a company release, and is assembled with an airframe and propulsion system manufactured entirely at X-Bow factories, thus eliminating a production bottleneck that has plagued myriad high-priced systems reliant on multi-company components. Axios first reported about the X-Bow Buckler.

The unveiling at London’s 2026 Farnborough Airshow this week is the latest push by U.S. industry to solve an interceptor enigma that has become increasingly glaring as the nation’s war with Iran drags on.

U.S. troops in the military’s Central Command area of operations have continued to face the onerous task of leaning on exorbitantly priced interceptors to contend with Iran’s vastly cheaper, mass-produced Shahed attack drones.

The use of a single PAC-3 interceptor to knock one Shahed-136 out of the sky comes with a $4 million to $35,000 tradeoff, or a 114-1 cost-per-kill ratio.

“You can’t win a war of attrition trading million-dollar interceptors against thousand-dollar threats,” X-Bow founder and chief executive officer Jason Hundley said in a release. “Buckler has flown, it comes in under $100,000, and we build its airframe and propulsion ourselves — the part of the industrial base that is so stressed by today’s munitions demands. This is our answer to the call from the U.S. and its allies: affordable capability, at scale.”

X-Bow’s announcement comes after the firm’s recent test of the Buckler munition — one that derives its name, as TWZ noted, from a Medieval era shield — that demonstrated its propulsion and flight performance, the company announced.

Following a similar theme at Farnborough, Lockheed Martin on Monday introduced what it hopes will be another low cost per kill solution to the ever-evolving unmanned threat.

The defense giant this week introduced the Morfius X-Rotor, a ground-launched “one-to-many” airborne high power microwave counter-UAS system the company says can “neutralize more than 50 enemy drones in a single flight.”

Morfius is built, most notably, to be recovered and reused.

Lockheed also introduced a cheaper Patriot interceptor.
