The Republic of Singapore Air Force has become the first service globally to field a fully certified Automatic Air-to-Air Refueling (A3R) capability on the Airbus A330 MRTT, following certification granted by Spain’s National Institute for Aerospace Technology (INTA). The system was unveiled at the Singapore Airshow.
The certification caps a multiyear development and flight-test campaign led by Airbus Defense and Space, working closely with Singapore’s Defense Science and Technology Agency and RSAF aircrews. The effort validated the system across a wide operational envelope, including daytime and nighttime refueling, multiple receiver aircraft types, and expanded mission profiles.
With certification now complete, Singapore’s A330 MRTTs, operated by 112 Squadron, can automatically detect, track, and connect to receiver aircraft without manual boom operator inputs. Using computer vision and advanced automation, the system reduces crew workload while improving precision and safety during one of the most complex phases of flight.
Most tanker fleets worldwide still rely on human boom operators making continuous fine corrections, particularly challenging at night,
in turbulence, or during long missions. A3R shifts that burden to software, a fundamental change in how aerial refueling is executed.
Major-General Kelvin Fan, Chief of Air Force at Republic of Singapore Air Force, said on the sidelines of the Singapore Airshow: ”This development will enhance the RSAF’s aerial refueling operations, contributing to greater operational effectiveness. It also reflects the RSAF’s commitment to working with industry partners to innovate and remain at the leading edge of technology.”
For the RSAF, the payoff is more than prestige. Automated refueling enhances mission endurance, reduces fatigue on long sorties, and improves safety, advantages that matter for a small air force operating far from home bases.
Once Boeing started work on a camera-based visual system for boom refueling, it was only a matter of time. As a retired KC-135 boom operator, this is bittersweet news. On the one hand, this should add another layer of safety to the aerial refueling equation. On the other, it’s sad to know that a career field with a long and storied history will go by the wayside.
True. I remember when Navs and FEs met the same fate on 130s.

Why make things more complicated than that? 😜
Because pilotless airplanes are the future and you will need automation to refuel.
Because the maximum flow rate on the probe and drogue system (up to ~600 gal/min) is only half that of a flying boom (up to ~1200 gal/min). (These values were found in open sources.) The Air Force operates larger receiving aircraft, so they use the system with the higher flow rate.
