SpektreWorks LUCAS

In July 2025, the company SpektreWorks first publicly presented a one-way attack drone, which it called LUCAS (Low-Cost Uncrewed Combat Attack System). It was described as a reverse-engineered copy of the Iranian Shahed 136 drone, which is also built in large numbers in Russia as Geran-2, and has been extensively used in the Russian attack on Ukraine. SpektreWorks hasn't published any detailed specifications on LUCAS itself. However, they provide some data on their FLM 136 target drone, which is also a Shahed 136 lookalike, designed to provide a realistic target for air-defense training against Shahed 136. LUCAS is most likely simply a "weaponized" FLM 136, and therefore the specifications might be quite similar.

FLM 136

LUCAS has been developed and evaluated under the U.S. Army's APFIT program (Accelerate the Procurement and Fielding of Innovative Technologies; sometimes described as Applied Small UAS Prototype Innovation Transition). In December 2025, the U.S. Central Command announced the establishment of a Special Operations Command unit in the Middle East, called Task Force Scorpion Strike (TFSS). One of the tasks of TFSS is to employ LUCAS drones in an operational environment.
