Low-cost interceptors dominate Farnborough as air defense demand surges

The Farnborough International Airshow opened Monday in Hampshire, England, with defense technology and weapons systems commanding an outsized share of attention as militaries around the world scramble for affordable answers to the drone and missile threats reshaping modern warfare.

Low-Cost Interceptors Take the Spotlight

X-Bow Systems, the New Mexico-based solid rocket motor manufacturer, used the show's opening day to unveil an interceptor called Buckler — a flight-tested weapon priced below $100,000 and designed to destroy the kind of medium-sized drones that have become a defining feature of recent conflicts. "This is our answer to the call from the U.S. and its allies: affordable capability at scale," CEO Jason Hundley told Axios in an exclusive report published Monday. The interceptor's airframe, motor, and propellant are all built in-house, and it is intended to defeat Group 3 drones — a class that includes platforms modeled on Iran's Shahed-136. "You can't win a war of attrition trading million-dollar interceptors against thousand-dollar threats," Hundley said. The Pentagon has already requested a briefing on the weapon.axios

The cost pressure runs up the supply chain. Lockheed Martin ↗ 1.08% announced Monday a new Patriot interceptor variant called the PAC-3 Adapted Capability Effector, or ACE, which the company said would cost less than half the roughly $4 million price of its current PAC-3 MSE missile, according to Reuters. Initial production could begin within 36 months, with development planned alongside U.S. and European partners. MBDA also unveiled an upgrade to its ground-launched Asraam air defense system, pairing the missile with a lower-cost interceptor, according to Aviation Week.reuters+2

Israeli Firms Showcase Battle-Proven Systems

Rafael Advanced Defense Systems arrived at Farnborough with what it calls a portfolio of combat-tested weapons, headlined by Iron Beam, the world's first operational laser-based air defense system, which was formally delivered to the Israeli Air Force in late December 2025. Israel Aerospace Industries and Elbit Systems ↗ 1.33% are also exhibiting operationally proven defense solutions aimed at European buyers, according to the Jerusalem Post.defence-blog+3

A Broader Industry Shift

The emphasis on defense at this year's show reflects deepening global demand for air defense systems driven by conflicts in Ukraine, the Middle East, and broader geopolitical instability. X-Bow, which has secured over $280 million in Pentagon contracts to expand America's solid rocket motor supply chain, completed certification of a new production facility in Texas in May and has delivered more than 1,100 rocket motors under existing contracts. The company's presence at Farnborough — alongside established primes racing to cut interceptor costs — underscores how quickly the economics of air defense have moved to the center of military planning worldwide.defence-blog
