SkyLab UA

SkyLab UA is a Ukrainian defence-technology company founded in 2022 by Yevhen Rvachov, an engineer from Balakliia in the Kharkiv region who began the work after fleeing his occupied hometown and later moved operations to Kyiv. Its main product is the Sirko-S1, a wheeled multipurpose unmanned ground vehicle.

The Sirko-S1 is a four-wheel-drive electric platform — later versions run on airless wheels developed with a state grant — carrying roughly 130 to 200 kilograms. It is built to be modular: the base vehicle moves ammunition, supplies, and medicine, evacuates wounded soldiers, and carries a reconnaissance package of thermal imager, laser rangefinder, and 360-degree camera, while bolt-on modules add remote demining and automated mine-laying. The company also builds at least one aerial system, the Shoolika mk6, a strike multicopter designed to resist electronic warfare and operate at night.

Ukraine’s Ministry of Defence has codified the Sirko-S1 and procures it for the Defence Forces, describing it as among the first ground robotic transport platforms to be codified and deployed; the ministry says it has been bought by the state for more than two years and fielded across the front. It has been used by units including the Azov Brigade. Development was supported by volunteer crowdfunding and a grant from Ukraine’s state defence-tech cluster, Brave1 , which funded the airless-wheel work; no priced investment round has been disclosed.
