LUCAS — the Low-cost Uncrewed Combat Attack System — is the US military’s answer to the Iranian Shahed-136 : a long-range, one-way attack drone built to be fielded in quantity and lost cheaply. Its maker, SpektreWorks of Phoenix, Arizona, took a captured Shahed airframe and rebuilt it around American electronics and guidance, arriving at a platform CENTCOM prices at roughly $35,000 a unit. Physically it mirrors its inspiration: about three metres long with a 2.4-metre wingspan, a small 215 cc piston engine, and a range near 800 kilometres.
The platform moved from public debut to combat with striking speed. SpektreWorks unveiled LUCAS in July 2025; by 3 December 2025, US Central Command had stood up Task Force Scorpion Strike, described as the first US one-way attack-drone squadron in the Middle East. The first ship-launched LUCAS flew from the littoral combat ship USS Santa Barbara on 16 December 2025. Its first officially confirmed combat use came on 28 February 2026 during Operation Epic Fury, the joint US–Israeli strikes on Iranian command, air-defence, and missile-launch sites — the first time the US had fired a long-range one-way attack drone in combat.
The more consequential change is autonomy. In May 2026 the Office of the Under Secretary of War for Research and Engineering selected Shield AI to integrate its Hivemind software — the same AI pilot that has flown V-BATs, F-16s, and Navy targets in GPS- and comms-denied conditions — onto LUCAS. Hivemind is meant to serve as the drone’s AI pilot, letting a single operator command a swarm that coordinates manoeuvres, redistributes targets, and adapts in real time while humans keep control of the strike decision. An operational demonstration of one operator directing a LUCAS swarm was planned for autumn 2026.
LUCAS sits at the intersection of two trends Robot War tracks closely: the spread of cheap, mass-produced strike drones first proven by the Shahed, and the layering of edge autonomy on top of them. SpektreWorks supplies the airframe; Shield AI supplies the brain.
Combat experience
LUCAS was revealed publicly in July 2025 and moved into operational service unusually fast. CENTCOM announced Task Force Scorpion Strike — described as the US military’s first one-way attack-drone squadron in the Middle East — on 3 December 2025, with LUCAS drones already in hand. The first ship-based launch followed on 16 December 2025 from the littoral combat ship USS Santa Barbara in the Arabian Gulf.
The first officially confirmed combat use came on 28 February 2026 during Operation Epic Fury, the joint US–Israeli strikes against Iranian command-and-control, air-defence, and missile-launch sites — making LUCAS the first long-range US one-way attack drone used in combat. Earlier operational use was reported in January 2026 (Operation Absolute Resolve, Venezuela). The maker, SpektreWorks , built the airframe by reverse-engineering a captured Shahed.
Effectiveness
LUCAS’s headline argument is cost-exchange: at roughly $35,000 a unit it brings Shahed-class mass and range to US forces at a fraction of the price of a cruise missile, which is the same economic logic that made the original Shahed effective for Iran and Russia. Published per-strike outcomes remain sparse — reporting frames it as a low-cost, scalable deep-strike option rather than citing hit statistics.
The capability is set to change sharply with autonomy. In May 2026 the Office of the Under Secretary of War for Research and Engineering selected Shield AI to integrate its Hivemind AI pilot onto LUCAS, so that a single operator can direct a swarm that coordinates manoeuvres, re-distributes targets, and adapts in comms-denied conditions while humans retain the strike decision. An operational demonstration was planned for autumn 2026.
