Castelion Blackbeard

A startup's bet that hypersonic weapons can be made cheap and in bulk. Castelion — founded by ex-SpaceX engineers — is building Blackbeard, a Mach 5+ long-range strike missile aimed at roughly $300,000 a round and 500 a year, applying the drone war's "affordable mass" logic to a class of weapon that legacy primes deliver at $40 million-plus per round. The thesis is compelling; almost none of it is proven yet.

Overview

Blackbeard is the first product of Castelion, a US defense startup founded in 2022 by former SpaceX engineers (CEO Bryon Hargis): a low-cost, mass-producible hypersonic strike missile flying at Mach 5+ (over 3,800 mph) with sustained flight and terminal maneuver. Its entire reason for existing is economic — to take the "affordable mass" logic that cheap drones brought to the battlefield and apply it to hypersonics, a category previously owned by a few primes at tens of millions of dollars per round. It exists in two variants off one core: a ground-launched version for the US Army and an air-/sea-launched version for the US Navy's MACE program. For BattlePolicy it is the strike-missile face of the neo-prime "affordable mass" story. The essential caveat up front: nearly every hard specification below is a budget-document goal or requirement, not demonstrated performance — the program's momentum (contracts) is real; its capability is not yet proven.

Development

Castelion runs a vertically integrated, rapid-test "SpaceX for missiles" model, and has reported on the order of 25 test events. The contract momentum through 2026 is the story: an FY26 Army request of $25M, a February 2026 Navy MACE down-select worth ~$50M, an April 2026 ~$105M award to integrate Blackbeard on the F/A-18, a May 2026 framework agreement for 500 weapons a year, and — on 16 June 2026 — the first delivery order, $23.4M for 50 pre-production units. Early operational capability is targeted for 2027. The company is also building Project Ranger in Rio Rancho, New Mexico — a ~1,000-acre, $220-250M self-funded site billed as the largest dedicated US hypersonic facility.
