US deploys low-cost ‘Lucas’ drone inspired by Iranian design in war. Wall Street Journal report (gated)
Summary:
US deploys low-cost “Lucas” drone built from reverse-engineered Iranian tech
Rapid development marks shift toward cheaper, scalable warfare systems
Drones used in strikes on Iranian military and IRGC infrastructure
Cost efficiency contrasts sharply with traditional US munitions
Highlights both progress and gaps in US defence readiness
A low-cost attack drone developed by the US military using reverse-engineered Iranian technology is emerging as a defining feature of the current conflict, underscoring a major shift in how modern warfare is being approached.
The system, known as the FLM-136 or “Lucas,” was designed in under two years and deployed early in the war, where it has been used in strikes against Iranian military targets, including weapons facilities, drone production sites and air-defence systems. Senior defence officials say the strikes contributed to a sharp decline in Iranian drone activity in the early phase of the conflict.
Unlike traditional US defence programs, often characterised by long development cycles and high costs, Lucas reflects a new strategy focused on speed, scale and affordability. The drone, described by former officials as the “Toyota Corolla of drones,” is built to be mass-produced and expendable, with unit costs estimated between $10,000 and $55,000. That compares with legacy systems such as Tomahawk cruise missiles, which cost upwards of $2 million each.
The origins of the program trace back to US military planning for a potential conflict with China, where simulations showed that critical munitions stockpiles could be depleted within weeks. In response, defence planners prioritised the development of low-cost, long-range strike systems capable of being produced rapidly and at scale.
The Lucas drone was developed by reverse-engineering an Iranian Shahed drone recovered from Ukraine, marking a rare instance of the US adopting adversary technology as a blueprint. The Pentagon has retained intellectual property control, allowing it to tap a broader network of manufacturers to scale production quickly, with multiple firms expected to produce hundreds of units per month.
While the system has proven effective in the current theatre, where Iranian air defences are relatively degraded, questions remain over its performance in more contested environments, particularly against advanced electronic warfare and GPS jamming capabilities.
More broadly, the deployment highlights both progress and vulnerability. While the US has demonstrated it can rapidly field cost-effective systems, officials warn that gaps remain in counter-drone capabilities and in the broader supply of scalable, modern military hardware, raising questions about readiness for more complex future conflicts.
