Castelion Wins $105M U.S. Navy Contract for Blackbeard Hypersonic Weapon

This article is based on an official press release from Castelion.

Defense technology company Castelion has secured a $105 million contracts from the U.S. Navy to advance the integration of its Blackbeard hypersonic strike weapon onto the F/A-18 Super Hornet. The agreement aims to transition the advanced weapon system to an Early Operational Capability (EOC) by 2027.

According to a company press release, the newly awarded funds will support extensive system safety and certification testing, alongside flight testing and other critical integration activities required for carrier-based operations. This development marks a significant step in the Navy’s push to equip its carrier air wings with next-generation hypersonic capabilities.

The $105 million award builds upon previous investments by the military branch, reflecting a sustained effort to accelerate the deployment of affordable and scalable hypersonic deterrents to the fleet.

Advancing the Blackbeard Hypersonic System

The Blackbeard system is Castelion’s flagship hypersonic weapon, engineered specifically for rapid, industrial-rate production and commercial unit cost efficiency. Under the terms of the new contract, the company will focus on completing the hardware and software integration of the weapon onto the F/A-18E/F airframe.

A major component of the contract involves executing the rigorous system safety and airworthiness certification process mandated for naval aviation. As noted in the Castelion release, this non-negotiable certification ensures the weapon is approved for safe storage, loading, and carriage aboard an aircraft carrier operating at sea.

“The U.S. Navy’s commitment to fielding affordable, innovative hypersonic capability reflects the kind of leadership this moment demands and clear determination to move fast for the warfighter,” said Bryon Hargis, CEO and Co-Founder of Castelion. “We’re grateful for the continued trust in Blackbeard and in our team.”

A Timeline of Accelerated Naval Investment

The U.S. Navy has demonstrated a clear strategy to rapidly move new capabilities from the prototype phase to the operational fleet. This latest $105 million contract follows a previous $49.9 million award granted to Castelion in February 2026, which was designed to advance the Blackbeard system from prototype to production.

By sequencing these milestones, the Navy is maintaining operational rigor while accelerating the timeline for fielding advanced strike weapons. Castelion, which operates out of Torrance, California, with manufacturing facilities in New Mexico and Texas, has positioned the Blackbeard system to meet the Department of Defense’s objective of building credible, nonnuclear deterrent capacity at scale.

AirPro News analysis

The rapid succession of contracts awarded to Castelion highlights a broader strategic shift within the U.S. military toward acquiring cost-effective, mass-producible hypersonic weapons. Traditional hypersonic development programs have often been plagued by high costs and extended timelines. By partnering with agile defense-tech startups, the Navy is signaling a willingness to adopt commercial production methodologies to achieve Early Operational Capability faster than legacy acquisition pathways typically allow.

Integrating a new hypersonic weapon onto the F/A-18 Super Hornet by 2027 is an ambitious target that underscores the urgency of modernizing carrier strike group capabilities. If successful, the Blackbeard program could serve as a template for future rapid-fielding initiatives across other branches of the armed forces.
