But will it work?
While the Struna-1 bistatic radar is not a be-all end-all detection solution for stealth aircraft, it could pose a significant threat to stealth NATO aircraft in a future conflict. Strike aircraft with stealth features are particularly vulnerable, the strike role tends to favor flight profiles that might cause aircraft to fly into the Struna-1’s detection range. In tandem with other modern “stealth-defeating” radar systems, the Struna-1 could provide critical information to an adversary on the position and movement of stealth aircraft.
Ever since the development of stealth technology for aircraft, many different systems have been advertised as “stealth killing.” One of the more innovative solutions is the Russian Struna-1/Barrier-E bistatic radar system developed by NNIIRT, a division of the Almaz-Antey Joint Stock Company. Almaz-Antey is the premier air-defense and radar manufacturer in Russia; they make the Tor, Buk and S-400 anti-aircraft systems, as well as their respective search radars. The Struna-1 was originally developed in 1999. A further evolution of Struna-1, the Barrier-E system was later showcased for export at MAKS 2007. While it is not part of Almaz-Antey’s online catalog, it was shown alongside other radars at MAKS 2017. The system is rumored to be deployed around Moscow.
