Resolute Eagle
A long-endurance Group 3 UAS with two quick-change configurations.
The Resolute Eagle is a long-endurance Group 3 unmanned aircraft system (UAS) built and run by Resolute ISR, Inc., based in Howell, Michigan. It is a single platform that offers two configurations: a standard fixed-wing version and a hybrid VTOL variant, and switching between them takes under half an hour.
The fixed-wing configuration launches from a low-pressure pneumatic launcher and lands on a belly skid using a Kevlar skid plate. The hybrid VTOL version adds two battery-powered booms with four propellers. Both configurations are controlled by an Applied Navigation Quattro autopilot. The aircraft is powered by a 33-horsepower multi-fuel engine from XRDi.
Resolute ISR acquired the Resolute Eagle’s intellectual property and assets from AATI in August 2020. Both XRDi and Resolute ISR are fully owned by Heligroup, Inc.
From April 1 to May 27, 2025, the Resolute Eagle took part in the U.S. Naval Forces Southern Command / U.S. 4th Fleet Hybrid Fleet Campaign (HFC) Fleet Experimentation (FLEX) held in San Salvador, El Salvador.
The aircraft is built around Modular Open Systems Architecture (MOSA) principles and serves as a long-endurance, multi-intelligence platform. Its current payloads include Trillium HD-80/95 cameras, IMSAR NSP (3, 5, and 7), Arkeus HSOR, Silvus StreamCaster SC4200-SC4400 MN-MIMO radios, Bandit 2x, PLEO SATCOM communication links, and MPU5 mobile ad hoc network (MANET) radios.
Other hybrid VTOL UAS in this category include the Textron Systems Aerosonde HQ SUAS, IAI/Hankuk Carbon Panther FE, Arcturus JUMP-20, and KWT-350 VTOL Fixed-wing UAV.

Lore & Background
The Resolute Eagle was originally developed by AATI, which sold the UAS intellectual property and assets to Resolute ISR, Inc. in August 2020. Both XRDi and Resolute ISR are wholly owned by the Heligroup, Inc. The aircraft is designed with Modular Open Systems Architecture (MOSA) principles and serves as a long-endurance, multi-intelligence platform. In April to May of 2025 (April 1 to May 27), the Resolute Eagle participated in the annual U.S. Naval Forces Southern Command / U.S. 4th Fleet Hybrid Fleet Campaign (HFC) Fleet Experimentation (FLEX) in San Salvador, El Salvador. The standard fixed-wing configuration launches via a low-pressure pneumatic launcher and recovers using a belly-skid landing with a Kevlar skid plate. The hybrid VTOL configuration adds two battery-powered booms with four propellers. Current payloads include the Trillium HD-80/95 cameras, IMSAR NSP (3,5 and 7), Arkeus HSOR, Silvus StreamCaster SC4200-SC4400 MN-MIMO Radio, Bandit 2x, PLEO SATCOM communication links, and MPU5 mobile ad hoc network (MANET) radios.
Reader's Guide
The Resolute Eagle represents a flexible approach to Group 3 UAS design, offering both conventional and VTOL capabilities within a single airframe. Its ability to switch between configurations in under 30 minutes allows operators to adapt to mission requirements without procuring separate systems. The aircraft's participation in the 2025 Hybrid Fleet Campaign Fleet Experimentation demonstrates its integration into U.S. naval experimentation efforts. The use of a multi-fuel engine and MOSA-based payload integration supports multi-intelligence missions with a variety of sensors and communication links. The transfer of intellectual property from AATI to Resolute ISR in 2020, and the ownership structure under Heligroup, Inc., provide context for its development and production. The Resolute Eagle is one of several hybrid VTOL UAS on the market, alongside systems such as the Textron Systems Aerosonde HQ SUAS, IAI/Hankuk Carbon Panther FE, Arcturus JUMP-20, and KWT-350 VTOL Fixed-wing UAV.
