In 2013, AgustaWestland was given a Royal Navy contract for the SW-4 Solo's development as part of the UK's RWUAS (Rotary Wing Unmanned Air System) Capability Concept Demonstrator (CCD) programme. Development of the SW-4 Solo is also being supported by the Italian Ministry of Defence 's Directorate for Air Armaments under the Italian National Military Research Plan.

An alternative engine is provided in the form of the 460 kW (615 shp) Pratt & Whitney Canada PW200 /9 turboshaft engine. The main rotor is fully articulated and the rotor blades on both the main and tail rotors are composed of composite materials.
