US Navy tests GPS-free autonomous drone recovery on moving ships
NAWCAD software uses onboard cameras and motion sensors to guide an uncrewed aircraft onto a moving ship when GPS is unavailable.
The US Navy has tested software that lets an uncrewed aircraft recover aboard a moving ship without relying on GPS or dedicated shipboard tracking equipment, according to TechRadar's report on the demonstration.1
The work comes from the Naval Air Warfare Center Aircraft Division, or NAWCAD. Its software uses cameras, motion sensors and algorithms to identify the vessel, calculate its movement and guide the aircraft towards a deck that is still pitching beneath it.1
That approach could reduce the need for specialised tracking hardware and extra landing equipment. Traditional autonomous recoveries can require ship modifications and dedicated systems, increasing both procurement costs and the effort needed to integrate an aircraft with a vessel.
The demonstration is designed for conditions in which satellite navigation is unavailable or deliberately disrupted. NAWCAD engineer Peter Arslanian described GPS as the first operational link an adversary would try to sever in a high-end maritime conflict, while Rear Adm. Todd Evans said autonomy could give sailors an advantage when satellites and communications are jammed.1
NAWCAD now intends to move the capability towards operational testing. Possible applications include the Navy's Small Tactical Unmanned Aircraft Systems programme, its Collaborative Combat Aircraft initiative and DARPA's Early VTOL Aircraft Demonstration programme, known as EVADE.1
The report also makes clear that the demonstration is not the same as a fielded capability. Reliability and compatibility still need to be established across individual aircraft designs before the software can be treated as a universal replacement for shipboard recovery equipment.
Our opinion
This is the sort of military autonomy story that matters less because it removes one piece of equipment and more because it changes the assumptions around operating in a contested environment. A drone that can judge a moving deck through onboard sensing is not immune to failure, but it has a better chance of remaining useful when an opponent attacks the infrastructure its operators normally depend on. The next meaningful test will be operational reliability across different aircraft and sea conditions, not another controlled demonstration. Until that evidence arrives, NAWCAD's work is promising engineering rather than a finished naval system.
