LUCAS — the Low-cost Uncrewed Combat Attack System — is a family of expendable attack drones produced by SpektreWorks, an Arizona-based defense contractor, for the United States Armed Forces. The system was developed by reverse-engineering captured Iranian HESA Shahed-136 drones, incorporating American targeting, communication, and autonomy improvements into the basic airframe concept. Admiral Brad Cooper, commander of U.S. Central Command, described the program with characteristic directness: “We captured it, pulled the guts out, sent it back to America, put a little ‘Made in America’ on it, brought it back here and we’re shooting it at the Iranians.”
Specifications
LUCAS is a delta-winged, propeller-driven loitering munition approximately ten feet long with an eight-foot wingspan. Unit costs range from 55,000 depending on configuration — compared to roughly $2.5 million for a Tomahawk cruise missile. The system can be launched from catapults, rocket-assisted takeoff rails, and mobile ground or vehicle-mounted systems, as well as from naval vessels.
Technical distinctions from the Shahed-136
While LUCAS inherits the Shahed’s basic aerodynamic form, its internal systems represent a generation of improvement. The Shahed relies primarily on static GPS coordinates for terminal guidance; LUCAS employs vision-based object recognition to identify specific military hardware, a capability designed to reduce collateral damage and enable strikes against mobile targets. LUCAS also offers modularity beyond the Shahed’s single-purpose explosive role: variants can function as sensors, electronic jammers, or communication relays. Some variants are equipped with Starlink terminals for beyond-line-of-sight coordination, enabling autonomous swarming and cooperative tactics that the Shahed architecture cannot support.
Operational history
CENTCOM established Task Force Scorpion Strike in December 2025 to organize one-way attack drone operations, deploying LUCAS to the Middle East and completing the first naval ship launch test in late 2025. The system saw its first confirmed combat use on 28 February 2026 during Operation Epic Fury, the U.S. component of the joint U.S.-Israeli strike campaign against Iran. LUCAS drones struck IRGC command and control facilities, air defense sites, missile and drone launch positions, and military airfields. Admiral Cooper characterized the system as “indispensable,” particularly for preserving magazine depth — the finite stockpile of expensive precision munitions that a sustained campaign rapidly depletes.
The term “squadron” applied to Task Force Scorpion Strike did not denote a fixed number of aircraft; officials stated the unit “could be 100 or 2,000,” reflecting the system’s deliberately expendable design philosophy. Exact deployment numbers remain undisclosed.
Strategic significance
LUCAS represents a structural shift in the economics of air power. When a 2.5 million cruise missile, the cost calculus of precision strike inverts. The system also creates an asymmetric burden on the defender: intercepting a LUCAS with a PAC-3 missile costs roughly 300 million AN/TPS-59 radar facility in Bahrain, demonstrating that a single penetrating drone can impose costs orders of magnitude greater than its own.
The program validates the broader doctrinal concept of attritable mass — that mass-produced, expendable platforms can contest denied airspace and sustain strike campaigns at costs that allow indefinite continuation. This logic, first demonstrated by Iran’s own Shahed program, has been adopted, improved, and turned against its originator.
