Record-low cost and 400 km range: U.S. tests Rusty Dagger missile for Ukraine

The missile is being developed by the U.S. company Zone 5 Technologies under the ERAM program. It is also reported that the missile is already ready for serial production.

The report says the missile has successfully completed testing with a live warhead. The publication adds that the weapon could be a “game changer” due to its 400-kilometer (250-mile) range and record-low cost.

At the test range of Eglin Air Force Base, Zone 5 Technologies demonstrated the system’s capabilities. The missile not only flew its planned route but also struck the target with high precision using a live warhead, confirming its effectiveness.

The base’s press office said the tests made it possible to collect data for further development.

Earlier, in August 2025, the Defense Security Cooperation Agency reported that the U.S. State Department had approved a possible sale to Ukraine of ERAM missiles and satellite equipment worth about $825 million.

The agency said the purchase would be financed with support from Denmark, Netherlands, Norway, and funds from the U.S. Foreign Military Financing program. The main contractors would be Zone 5 Technologies and CoAspire.

On Aug. 24 of the same year, Wall Street Journal, citing two U.S. officials, reported that the administration of President Donald Trump had approved the sale of 3,350 ERAM missiles to Ukraine.
