RAF jets have been deployed in a dramatic response to a NATO alert, with flight trackers capturing their activity over Scotland. An Airbus KC2 Voyager, call sign Tartan31, took off from Brize Norton at 5.57am and was observed by Flightradar24 making multiple loops along the northern Scottish coastline.

Additionally, a Eurofighter Typhoon, call sign Phanto11, launched from RAF Lossiemouth and followed a similar pattern. The aircraft continue to patrol the area, with their exact mission remaining undisclosed. The RAF KC2 Voyager Tartan is broadcasting the squawk code 1321, indicating NATO Air Policing. Squawk codes ranging from 1301 to 1327 are designated for NATO air policing, which takes precedence in air defence situations. A scramble can occur under various circumstances, such as when an aircraft has an invalid or incorrect flight plan, loses contact with air traffic control, or fails to use its transponder correctly, reports the Mirror.

The unfolding situation in Scotland seems to be a QRA (Quick Reaction Alert), where missions are initiated to intercept and scrutinise unidentified or unauthorised aircraft breaching UK airspace. These fighter jets are on standby to react swiftly to any potential threats.

This is not the first time in recent months that RAF jets have been scrambled to respond to a threat. In November, fighters were launched to intercept a Russian military aircraft flying off the east coast of the UK over the North Sea.

The Ministry of Defence (MoD) confirmed that two Typhoons from RAF Lossiemouth were sent out to monitor a Russian Bear-F reconnaissance craft.

The plane was detected in the UK’s “area of interest,” but according to an MoD spokesperson, it did not infringe sovereign airspace. The operation was part of the RAF’s Quick Reaction Alert, which maintains high readiness 24/7 to protect UK skies.

Meanwhile, on Sunday, Russia deployed TU-95MS nuclear-capable bombers to unleash a fresh wave of missile strikes on Ukraine.

In response, NATO scrambled jets to patrol airspace near Ukraine’s border. Poland confirmed its own planes and that of allies had been deployed, citing “intensive activity” prompted by Russia’s activity.

"The RSZ Operational Commander activated all available forces and resources at his disposal," Poland’s armed forces said in a statement. "Fighter pairs have been scrambled, and ground-based air defence and reconnaissance systems are at the highest readiness."
