Overview

Rook is an autonomous hypersonic cargo rocket that delivers 250 kg (550 lbs) of payload up to 750 km (450 miles) in approximately 15 minutes. It launches from a standard 40-foot shipping container and lands on unprepared surfaces, requiring no runways or fixed infrastructure. The vehicle flies point-to-point at hypersonic speeds through space, re-entering the atmosphere to deliver cargo to austere locations. Completed tethered flight testing of a small-scale prototype and successful engine hot-fire testing.
