Why It Matters
Its low cost and rapid fielding give the Air Force a mass‑attritable strike option, preserving airpower relevance against sophisticated anti‑access defenses and supporting NATO allies.
Key Takeaways
- •Live-fire test of Rusty Dagger succeeded at Eglin Base
- •Missile offers 500‑lb warhead, 280‑mile range at subsonic speed
- •Designed for affordability, enabling mass deployment in prolonged conflicts
- •Open‑weapon platform allows modular integration across multiple launch aircraft
- •Potential foreign sale of 3,350 ERAMs to Ukraine underscores NATO collaboration
Summary
The U.S. Air Force announced a successful live‑fire demonstration of the Rusty Dagger missile, the first operational milestone for the Extended Range Attack Munition (ERAM) program. Conducted on Jan. 21 at Eglin Air Force Base, the test validated the missile’s live warhead detonation and gathered performance data for further refinement.
The Rusty Dagger is a sub‑sonic, air‑launched cruise missile carrying a 500‑lb warhead with an advertised range of up to 280 mi (450 km) and a top speed around 430 mph. Developed by Zone 5 Technologies and CoAspire under a $225 million contract, the design emphasizes modularity, a pyro‑free engine start, and low unit cost, enabling rapid, attritable production. The test met all key objectives within an unprecedented two‑year schedule from contract award to live fire.
Brig. Gen. Robert Lyons III highlighted the “speed of relevance” in delivering lethal, cost‑effective capability, while Brig. Gen. Mark Massaro stressed the need for asymmetric, mass‑attack options. The Department of State’s recent approval of a possible foreign‑military sale of up to 3,350 ERAM missiles to Ukraine, funded by NATO allies, illustrates the system’s strategic export potential.
If fielded at scale, Rusty Dagger could give U.S. and partner forces a budget‑friendly standoff weapon capable of saturating dense A2/AD environments, preserving aircrew safety and sustaining high‑tempo strike operations in future peer‑level conflicts.
Original Description
The U.S. Air Force has released details of the live-fire test of the Rusty Dagger , one of two new missiles being developed under Extended Range Attack Munitions (ERAM) program.
It was stated that on Jan 21, the Air Force conducted a warhead test of the new standoff cruise missile.
The trial took place at Eglin Air Force Base and brought together multiple stakeholders, including the Air Force Life Cycle Management Center’s Armament Directorate, the 96th Test Wing, and several industry collaborators.
According to the Air Force, the event achieved all key test goals, most notably the successful functioning and detonation of the missile’s live warhead. Engineers at Eglin gathered extensive performance data during the event, which will be used to continue refining and advancing the ERAM design toward operational maturity.
While the official Air Force release did not explicitly identify the weapon as the Rusty Dagger, imagery released alongside the announcement leaves little doubt about its identity.
A sequence of photographs shows the missile descending almost vertically toward a stationary target before the warhead detonates on impact. The service has not disclosed which aircraft or platform was used to launch the missile during the demonstration.
Separately, Zone 5 Technologies, the developer of the Rusty Dagger, publicly acknowledged the successful test through a post on its LinkedIn page, reinforcing the significance of the milestone and confirming industry involvement in the event.
