US Army-backed aircraft delivers cargo three ways in single sortie without ground crews

Elroy Air has expanded the mission profile of its autonomous Chaparral cargo aircraft with three new unattended delivery modes developed for the U.S. Army, allowing the drone to deliver supplies without personnel or equipment at the receiving site. The new capabilities let the aircraft release cargo from a hover, drop payloads while flying forward, or land and unload autonomously, giving military units more options to resupply forces operating in contested or remote areas. The California-based company demonstrated the new delivery modes during a July 15 flight test at its Byron headquarters. Engineers programmed the aircraft to complete two autonomous payload drops during a single sortie without operator intervention during the release sequence, meeting requirements for communications-denied environments. Three delivery options During the demonstration, Chaparral first released a 68-pound payload while hovering over the target area. The aircraft later dropped a second 70-pound payload from forward flight at an altitude of 65 feet. Both deliveries relied on preloaded coordinates and required no personnel at the landing zone. Elroy Air also completed a separate test of its ground delivery mode. After landing, the aircraft automatically released its cargo before departing, eliminating the need for ground crews or dedicated unloading equipment. Army officials requested the new delivery capabilities under an existing development contract. According to Elroy Air, the same software and hardware package will also support commercial logistics missions where infrastructure remains limited or unavailable. Chief Executive Officer Andrew Clare said the company delivered the requested capabilities on schedule and within budget. He added that field exercises with the U.S. Army will begin next as the service evaluates the system in operational scenarios. Clare said the aircraft’s autonomous delivery features also translate directly to civilian logistics applications. Built for contested logistics Chaparral uses interchangeable cargo pods, allowing operators to switch between missions without modifying the aircraft. The vertical takeoff and landing platform does not require a runway, fixed delivery equipment, or personnel at the destination, making it suitable for disaster response, maritime operations, and remote terrain. Military planners have increasingly focused on autonomous logistics as distributed operations place troops farther from traditional supply hubs. Cargo aircraft capable of delivering supplies without exposing pilots or support crews could reduce operational risk while improving the speed of battlefield resupply. Mark Rodrigo, who leads federal business development at Elroy Air and previously served as a U.S. Air Force intelligence officer, said contested logistics remains one of the military’s toughest operational challenges. He noted that a single Chaparral aircraft can now deliver supplies to multiple locations during one mission without placing a pilot in danger or requiring personnel at the drop site. Production plans advance The new delivery modes will become standard on production Chaparral aircraft built through Elroy Air’s manufacturing partnership with Kratos Defense & Security Solutions.Kratos announced on July 20 that it will produce the autonomous cargo aircraft at its expanding Sacramento, California, manufacturing facility. The partnership aims to scale production as military demand for autonomous logistics platforms continues to grow and commercial operators explore heavy-lift cargo drone applications.Recommended ArticlesGet the latest in engineering, tech, space & science - delivered daily to your inbox.Aamir is a seasoned tech journalist with experience at Exhibit Magazine, Republic World, and PR Newswire.
