Specially commissioned drones could soon be flying life-saving blood supplies across Wales under an ambitious new trial being hailed as a potential game-changer for rural healthcare.
At present, blood donations collected across Wales are processed in south Wales before being transported by road to hospitals and blood banks, a journey that can take several hours – particularly to west and north Wales. In a country where geography and distance remain a real challenge for the NHS, that delay can be critical.
The Dragon’s Heart project aims to transform that system. Its long-term ambition is to deploy heavy-lift medical drones capable of carrying blood directly to the scenes of accidents or to remote hospitals. The aircraft being developed weigh around 55lb (25kg), measure roughly 5.5ft (1.7m) across, and are designed specifically for transporting sensitive medical cargo.
A pilot phase, due to begin in early 2026, has been described by the Welsh Blood Service as both significant and exciting. During the trial, blood will be flown in temperature-controlled compartments housed within the body of the drone itself, accessed via a hatch in the top. This design helps maintain strict storage conditions while minimising vibration during flight.
The Welsh Blood Service confirmed that all blood transported during the trial will be rigorously tested on arrival. Flights will operate at heights of up to around 2,000ft (610m).
Peter Richardson, deputy director and head of quality, safety and regulatory compliance at the Welsh Blood Service, said patient safety and protecting donor contributions were paramount.
“Rest assured we will make sure that not only is the blood safe when it arrives for use, but that we don’t waste any of the incredibly valuable donations our generous donors give us,” he said.
The drones will be operated by Skyports Drone Services, a Buckinghamshire-based company that already runs drone operations worldwide. However, chief executive Alex Brown said the Welsh project would be genuinely world-leading.
“These aircraft are quite unique,” he said. “They can take off vertically like a helicopter and then transition into fixed-wing mode, flying like a plane.”
Mr Brown added that the drones could land in very small areas, fly distances of up to 62 miles (100km) and operate in winds of around 30 knots – conditions often encountered along Wales’s exposed coastline and upland areas.
Before any routine medical flights can begin, the project partners must satisfy the Civil Aviation Authority that the missions can be carried out safely.
“If we can get that right,” Mr Brown said, “we can connect medical practices and locations right across rural Wales and really bring the benefits of drone technology to communities that are currently hardest to reach.”
The partnership is being led by Snowdonia Aerospace Centre, based at Llanbedr airfield in Gwynedd – a site long associated with aviation testing and innovation.
Technical director Jeremy Howitt said the location offered an ideal environment to trial the technology, thanks to the large block of restricted airspace surrounding the airfield.
“It means the airspace is clear of other aircraft, so we can be confident we’re operating in a safe environment,” he said. “We’re also able to fly out over the sea, which removes underlying ground risk.
“That allows us to prototype all the systems together, demonstrate that they’re safe, and then look to migrate the operation to other parts of the country.”
The next planned phase would see drones flying blood supplies between the Welsh Blood Service headquarters at Talbot Green in Rhondda Cynon Taf and the blood store in Wrexham – a journey that could be shortened by around three hours.
Beyond that, the vision is to link blood stores directly with hospitals across Wales, creating what Mr Howitt described as dedicated aerial “corridors” for medical drones.
“What we’re trying to do is establish the equivalent of motorways and A-roads for drones across Wales,” he said. “Once those are in place, they could also support emergency responses within the same regions.
“And beyond the blood service, we’re already talking to the ambulance service about how this technology could support 999 responses.”
For the Welsh Blood Service, the appeal is clear. While it operates as an all-Wales service, its base in the south means deliveries to west Wales – and particularly to north Wales – are often limited to once a day unless there is an emergency.
“The idea of using drones is that instead of sending one large vehicle on a long journey each day, we can send multiple smaller loads,” Mr Richardson said. “That improves frequency, reduces waiting times, and allows us to respond far more quickly to patients’ needs across Wales.”
If successful, the project could mark a significant step forward in overcoming the logistical challenges of delivering critical healthcare services in one of the UK’s most geographically diverse nations.
