PLAN B is Spray Service’s project developing wheel solutions for Ukraine’s military. Our workshop was destroyed on July 6, 2026. Help the team return to tire filling for unmanned ground vehicles and continue its engineering work.

6 JULY 2026 · VYSHNEVE
The workshop was destroyed.
The purpose remains.
During a large-scale Russian attack and the subsequent detonation of an ammunition depot in Vyshneve, we lost the project’s production base: our workshop, equipment, tools and material stocks.
Read our storyWHY WE NEED HELP TO REBUILD
Our purpose is to support
Ukraine’s military.
Our work was built around military needs. Its price included materials, wages and day-to-day costs. We did not build up reserves sufficient to rebuild the entire workshop. The team and its experience remain; we need support to put them back to work.
OUR WORK
One process to restart.
Two paths to develop.
Modular wheel
Assembly and testing are still ahead.
DevelopmentLighter filling
Foamed materials to explore lower wheel weight.

FURTHER DEVELOPMENT
Lighter filling.
A separate development path.
This experimental sample belongs to our work on lighter filling. It is separate from the gel filling we plan to restart first. Further development needs restored equipment and testing.

THE NEXT STEP
The need remains.
The team is ready to return.
Requests for tire filling continue to come in. Around ten team members are ready to resume work. We need a workspace designed around their safety, followed by equipment and materials.
