Robinson Unmanned positions R44 Sprayhawk for large-scale agricultural application
Robinson Helicopter Company has created Robinson Unmanned, a business unit that includes a large agricultural aircraft called the R44 Sprayhawk. The aircraft is based on the company’s R44 helicopter platform and is configured for unmanned, ground-supported aerial application rather than passenger flight.
Robinson describes the Sprayhawk as a gas-powered vertical-takeoff-and-landing UAS with a 110-gallon liquid spray system. The company says a two-person crew operates it through a ground control station, with a single pilot overseeing flight. Its published design also includes fly-by-wire controls, 360-degree sensing, terrain-following and integrated spray-flow controls.
The manufacturer says the platform can apply more than 200 acres per hour and use a spray swath up to 60 feet wide. Those figures are company claims, not independently verified operational results. Robinson also says the aircraft uses shared R44 production components and can be incorporated into larger agricultural fleets.
Why it matters
The Sprayhawk shows how a conventional light-helicopter airframe is being adapted for uncrewed aerial work, particularly the low-level, time-sensitive tasks associated with crop treatment. Its eventual use will depend on applicable aviation approvals, operating limitations and agricultural chemical rules in each market, not solely on the aircraft’s stated technical capability.
