Keres

YC company profile

Kill the drone, keep the jet. Reusable unmanned interceptors.

Keres (KAIR-eez) builds reusable unmanned jet interceptors for air defense. The Garmur launches on cue, closes at jet speed, positively identifies and kills drones and cruise missiles, then lands to fly again. It gives commanders a fighter-class response at a fraction of the cost.
