The British Department of Defense announced the need to raise the fighter. The military even wants to restore it.
According to Voennoye Obozreniye, the plane has many classified systems and sensors. If they fall into the hands of Russia or China, the situation will be unpleasant for the British. Where exactly the fighter fell is unclear. And if it happened near Egyptian or Syrian waters, the likelihood that his data will get to the Chinese or Russian military increases.
According to the media, if the Russian military lifts at least one fragment of the aircraft, then the Russian defense industry will be able to reconstruct the technologies used in the fighter and then apply them in the Su-57 and Su-75. This applies in particular to stealth technologies.
