Castelion aims to produce roughly 500 missiles every year eventually
A California defense startup is now selling hypersonic missiles priced like a luxury vehicle rather than a mansion, marking a shift in weapons pricing.
Castelion's Blackbeard missile travels in excess of Mach 5 and reportedly costs under $300,000 per completed round, a fraction of typical hypersonic pricing.
The pricing became real on June 16 2026, when the US Navy ordered the first 50 production rounds for $23.4 million.
The order also covers 50 shipping and storage containers, running primarily through Castelion's sprawling New Mexico factory campus.
It is the third Navy payment in five months, following $50 million in February to push Blackbeard from prototype toward operational use.
In April 2026, the Navy committed a further $105 million specifically to integrate Blackbeard onto the F/A-18 and to run the carrier-suitability testing required before any missile can operate safely from a carrier deck.
According to Bryon Hargis, CEO and co-founder of Castelion, the funding reflects the Navy's commitment to "advancing affordable, manufacturable long-range strike capability."
Castelion was founded by former SpaceX engineers and has already completed more than two dozen flight tests within three years.
One of those flight tests took place at the Army's Dugway Proving Ground in Utah during the latter part of 2025.
Castelion has also partnered with uncrewed-boat maker Saronic to demonstrate launching Blackbeard missiles from a robotic surface vessel at sea.
If testing continues to succeed, the eventual plan is to purchase Blackbeard missiles by the thousand rather than by the dozen.
In May 2026, the company signed a framework agreement with the Department of War covering multi-year production of roughly 500 weapons annually.
The affordability behind Blackbeard rests heavily on components borrowed from several industries far removed from traditional aerospace manufacturing methods and vendors.
Chief Operating Officer Sean Pitt said the company uses automotive-grade Field-Programmable Gate Arrays originally built for driver assistance systems and electric vehicles.
These automotive processors cost roughly one-tenth as much as aerospace equivalents and arrive about six times faster, Pitt said.
Castelion has also replaced aerospace-grade metal tubing with precision-machined tubes originally designed for fracking operations in the oil and gas sector.
These tubes withstand heat and pressure levels comparable to rocket motor requirements, yet come from many more vendors at lower prices.
Rival startup Anduril has adopted a similar approach, using pharmaceutical-industry mixing technology to process rocket motor propellant far faster than legacy methods.
Castelion, recently valued at nearly $3 billion, has secured Pentagon contracts covering more than 500 hypersonic weapons under current agreements.
