Norwegian F‑35As intercept Russian Tu‑142 aircraft over the Bay of Biscay

The Bulgarian Military Portal reports that F-35A fighter jets of the Norwegian Air Force intercepted and escorted two Russian Tu-142MK maritime reconnaissance aircraft over the Bay of Biscay.

The Russians regularly conduct training flights outside their territory. Earlier this year, the Russian Federation's army sent Tu-22M3 bombers or MiG-31 fighters over the Baltic Sea several times. Many such incidents are met with immediate responses from NATO member countries, which react by scrambling fighters to intercept and subsequently escort the Russian aircraft.

It was no different in the case of the 15-hour flight, which two Russian Tu-142MK aircraft recently carried out on a route from Kipelovo to the Bay of Biscay and the North Atlantic. As explained by the Bulgarian Military, both planes were to cover a distance of 10,000 kilometres, and during the flight, they were intercepted by Norwegian F-35A fighters.

What exactly were the Tupolev Tu-142MKs doing over the Bay of Biscay, off the west coast of France? European sources cited by Bulgarian Military indicate that the Russian aircraft were on a special mission, specifically – calibrating a new over-the-horizon radar installed near Nizhny Novgorod, reads the report.

Bulgarian Military explains that Tu-142MK maritime reconnaissance and anti-submarine warfare planes play a key role in over-the-horizon radar calibration flights. These flights are by no means combat missions but rather test activities.

The mentioned Tu-142MKs are equipped with sensors and electronic systems designed to detect and track targets on and below the water's surface at long distances. The main goal of such flights is to properly tune the radars to ensure they can accurately detect targets and provide allies with reliable data, reads the report.

In a calibration flight, the Tu-142MK performs specific maneuvers over designated areas. There is no room for randomness in these places – every move is precisely planned to cover various environmental conditions and altitudes in calibration.

The main system installed on board the Tu-142MK is the Korshun-K radar. It monitors the area around the aircraft and detects targets. Additionally, a crucial element of the machine is the Berkut-95 magnetic anomaly detector.

This, in turn, is used to detect even minimal changes in the Earth's magnetic field, which the presence of large metal objects can cause, and thus submarines, which the Tu-142MK can detect and track. The identification and tracking of surface objects is carried out by electronic support measures that analyze all signals generated by potential targets.
