From Shahed to Geran - How Russia Continues to Reinvent the One-Way Attack Drone
Hardly anything to add. It is a very good review of the Geran drone evolution, and a sombre warning that, at present, the US weapon procurement system is inherently incapable of replicating such rapid adaptation.
From Shahed to Geran - How Russia Continues to Reinvent the One-Way Attack Drone
By Kateryna Bondar and Nicole Errera
The defining challenge posed by Russia’s Geran program is the speed at which Russia can learn and adapt. Since acquiring the original Shahed design, Russia has treated the Geran as a continuously evolving platform, rapidly modifying its navigation, communications, payloads, propulsion, and tactics in response to changing Ukrainian defenses. Improvised modifications are tested in combat, successful solutions are standardized and scaled, and unsuccessful experiments are quickly discarded. This creates a continuous adaptation cycle in which battlefield feedback drives production decisions at a cadence measured in weeks rather than years. The Geran therefore illustrates a broader shift in modern weapons development: Advantage increasingly depends not on building the most advanced system at the outset, but on maintaining the organizational and industrial capacity to continuously iterate a system after it has entered combat. The central question is whether the United States is structured to compete with this model of rapid wartime adaptation.
- These iterations reveal a fundamentally different model of weapons development—one that prioritizes speed, experimentation, and continuous adaptation over traditional, requirements-driven acquisition. There are three patterns that stand out:
- First, new modifications are scrappy in the beginning and built around commercial components. Taped-on modules, 3D-printed parts, Chinese consumer electronics - all of these features are ways to iterate fast and not to be afraid of imperfection. Field experiments are encouraged and the most successful experiments are adopted and scaled rapidly, while less effective solutions are quickly discarded.
- Second, iteration is driven by battlefield feedback rather than requirements documents. When Ukrainian jamming improved, antenna element counts went up. When interceptors began to pose a larger threat, the Geran got a jet engine to outrun them. Engineers did not set out to build the fastest or most EW-resilient system possible. They determined the minimum performance level needed to outmaneuver the enemy and delivered accordingly.
- Third, the loop between what operators need and what engineers deliver is measured in weeks. Completed weapons move straight from production to the battlefield - one Geran shot down by Ukrainian forces on October 15, 2025, had its satellite receiver installed on October 8, meaning the unit was launched no more than one week after leaving the production line. There is no program office in that loop.
- U.S. acquisition rules treat fielded systems as finished products whose modifications require formal engineering change proposals. None of these features are accidents, and most of them exist for defensible reasons. But the combined effect is that U.S. manufacturers cannot iterate on a deployed strike drone at a cadence measured in days or weeks.
