A New Class of Affordable Standoff Weapon

The U.S. Air Force has released details of a successful live-fire test of the Rusty Dagger, one of two new Extended Range Attack Munitions being developed under a crash program that could reshape the economics of cruise missile warfare. The test, conducted on January 21, 2026, at the Eglin Air Force Base range in Florida, saw the air-launched weapon fly to its target and detonate its warhead, meeting all key objectives.

Zone 5 Technologies, the defense contractor behind Rusty Dagger, announced that the Air Force demonstration featured the company's weapon as part of the ERAM effort, a program designed to produce low-cost, mass-producible cruise missiles that can be manufactured at a fraction of the price of existing standoff weapons like the AGM-158 JASSM.

Specifications and Capabilities

ERAM is understood to have a range between 150 and 280 miles, placing it firmly in the standoff category where launch aircraft remain outside the reach of most short-range air defense systems. The weapon is in the 500-pound class and carries a blast and fragmentation warhead with at least some degree of penetrating capability, making it effective against hardened targets as well as soft-skinned vehicles and field positions.

The emphasis on low cost and mass producibility is the defining characteristic of the program. While the Air Force has not disclosed unit prices, the entire ERAM initiative is built around the premise that modern conflicts demand munitions that can be produced in the thousands without breaking defense budgets. The lessons from Ukraine, where both sides have consumed vast quantities of precision munitions at unsustainable rates, have made this requirement urgent.

The Live-Fire Test

During the January 21 trial at Eglin, the project team met all key objectives, including successful full detonation of the warhead on target. While specific details about the flight profile, altitude, and guidance systems remain classified, the successful warhead detonation confirms that Rusty Dagger has progressed beyond the flight-test phase into weapons integration testing.
