The U.S. Navy’s Naval Air Warfare Center Weapons Division (NAWCWD) has successfully conducted the first-ever launch of a Solid Fuel Integral Rocket Ramjet (SFIRR) missile from an unmanned aerial vehicle — a technological milestone that promises to transform naval strike capabilities.

In addition to the groundbreaking launch, the test also integrated a fire control system on a BQM-34 target drone, resulting in a live fire demonstration that showcased advancements in high-speed, long-range weapons. Launching missiles from drones enables forces to engage distant targets with greater safety and precision.
“This successful integration validates key aspects of our design and brings us closer to delivering an advanced propulsion system that provides warfighters with greater range and speed,” said Abbey Horning, product lead at NAWCWD’s Advanced Concepts, Prototyping and Experimentation office.
Modern Propulsion Built on Proven Technology
While solid fuel ramjet technology is not new, this latest test confirms its relevance on today’s battlefield. According to Horning, the effort is not simply about reviving old ideas, but rather refining and modernizing them to meet current operational demands.
The SFIRR represents a significant advancement by simplifying missile propulsion through the elimination of the complexity found in liquid-fuel ramjets. This allows for lighter missiles with greater payload capacity, extended range, and improved maneuverability.
“The SFIRR offers a balance of affordability, reliability, and performance tailored to the Navy’s operational needs,” Horning added.
Innovation Directly Enhancing Combat Readiness
NAWCWD’s Deputy Director for Energetics, Ephraim Washburn, compared the technological evolution to the automotive industry: “We’ve been driving cars since the early 1900s, but that doesn’t mean we’ve stopped improving them.” He noted that solid ramjet investment peaked in the 1970s and 1980s, but the Navy is now reimagining it as a modern, effective propulsion solution.
This successful test is part of the Navy’s ongoing efforts to maintain technological superiority. NAWCWD works in collaboration with government, industry, and academic partners to deliver cutting-edge propulsion innovations that meet the demands of modern warfare.
“This is proven combat-capable technology,” Washburn concluded. “We are working to refine its range, endurance, and targeting capability.”
