Inside High-Speed Missions Fueling Western Jets on Russia’s Doorstep

ABOARD A BRITISH VOYAGER AIRCRAFT — With rows of economy seats, overhead baggage bins, television screens, and illuminated seatbelt signs, the cabin of this Royal Air Force tanker looks nearly identical to that of a commercial jetliner.

But out the window, NATO fighter jets are flying just a few feet away, receiving fuel from the Voyager at nearly 30,000 feet and at speeds around 300 miles per hour near the militarized Russian exclave of Kaliningrad. It’s a fast and dangerous job, where even the slightest mistake could be deadly.

The Voyager — essentially a flying gas station carrying enough fuel to keep fighter jets flying for thousands of miles — is the RAF’s only air-to-air refueling tanker, crucially allowing the UK to extend the range of NATO air operations.

Business Insider embarked on a Voyager flight this week for a NATO mission in support of Eastern Sentry, defensive operations that include air patrols launched in mid-September after roughly 20 Russian drones violated Polish airspace.

Since then, NATO fighter jets — enabled by the Voyager aircraft — have regularly flown patrols, missions, and training exercises along the Eastern flank of the alliance, serving as a warning to Russia.

‘We can operate anywhere’

Under the cover of clouds and darkness early Thursday morning, the Voyager — call sign KAYAK21— departed from base at RAF Brize Norton, west of London, for a nearly nine-hour journey that took the tanker over the Baltic Sea and Eastern Europe, and on the edge of Russian territory, before returning to England.

Several times during the journey, the Voyager refueled an assortment of British Eurofighter Typhoon and Swedish JAS 39 Gripen multirole fighter jets, a process that takes roughly 10 minutes. Finnish F/A-18s Hornets joined along at one point before splitting off.

The Voyager is based on the twin-engine Airbus A300-200. It became fully operational with the RAF in 2013, replacing the VC10 as the UK’s main tanker aircraft. It is typically staffed by two pilots and a mission systems operator, who facilitates the air-to-air refueling process.

The Voyager KC3 variant features two underwing pods for refueling fighter jets, equipped with retractable hoses, and a third centerline hose for larger aircraft.

Tankers like the Voyager or the US military’s KC-135 Stratotanker are designed to extend the range of fighter jets, early warning aircraft, and other aircraft, enabling longer-distance and duration air operations.

Aircraft would be limited in range or forced to spend time refueling at bases without the tankers, said one of the Voyager pilots, who, like other members of the crew, could not be named for security reasons.

With the air-to-air refueling capability, “we can operate anywhere in the world,” the pilot said.

In a demonstration of this capability, a Typhoon fighter took off from Scotland on Thursday and linked up with the Voyager over the North Sea. The jet traveled with the tanker over Eastern Europe and logged more than 2,000 miles by the time it returned to base.

This aerial refueling capability provided by the Voyager helps enable the NATO fighter jets to monitor Russian threats, as they are tasked with doing under the Eastern Sentry operation, the other pilot said.

The Voyager can carry up to 109 metric tons of fuel and nearly 300 passengers, although there were only 12 people aboard the tanker on Thursday, giving the feel of a severely undersold commercial flight on the world’s least-busy travel day.

Fighter jets take a very methodical approach to the fuel hose, inching closer until a locking mechanism connects the basket at the end of the hose trailing the tanker to a mechanical arm at the front of the jet.

Two aircraft operating in proximity are inherently dangerous, but a Voyager pilot said they reckon with this by training a lot and doing the refueling process very slowly.

The Voyager offloaded about 20 metric tons of fuel to the Typhoons and Gripens during the flight, which brought the tanker to the edge of Russian and Belarusian airspace as it slipped through the Suwałki gap, a thin corridor between those two countries that connects NATO members Lithuania and Poland.

Around here, the Voyager crew experienced some GPS interference — a common occurrence near Russian territory and one of the biggest issues that the tankers have to deal with, the mission systems operator said.

The Voyager has a defensive suite designed for some types of surface-to-air missiles, but it lacks protection against electronic attack. Still, the pilots were able to quickly mitigate the effect by switching over to other systems, they said.

GPS interference has been prominent in the Baltic Sea region for several years, but it has worsened amid Russia’s ongoing invasion of Ukraine, the mission systems operator said.

The operational tempo is high right now, with several Voyager flights operating daily out of RAF Brize Norton. The tankers aren’t always doing air-to-air missions; sometimes they’re transporting personnel or cargo.

Thursday’s mission focused on training with other nations, refueling the jets as they engaged in simulated combat with each other. It’s all part of NATO’s increased efforts to caution potential Russian activity in Eastern Europe just by being present in the area.

The message to Russia, one of the pilots said, is that “we’re using this airspace. And we’re using our rights to be in this airspace.”
