With Russia’s newest aircraft close to operationalization, the Five Eyes Air Force Interoperability Council (AFIC) decided to give Sukhoi’s Su-57 the codename “FELON.” The AFIC, which is staffed by the “Five Eyes” nations (Australia, Canada, New Zealand, the United States of America, and the United Kingdom), decides on reporting names for aircraft of NATO’s adversaries. The Su-57 has previously been referred to as “FRAZOR.” This designation did, however, only serve as a reporting name for the fighter aircraft’s development program (i.e. T-50).
NATO reporting names are used to simplify the myriad of GRAU designations, which are used by the Russian armed forces for its equipment. Reporting names are not randomly allocated, but follow a precise methodology. Fixed-wing aircraft receive reporting names beginning with code letters that indicate the aircraft’s mission. For example, reporting names for fighter jets always start with “F”/“FOXTROT” (e.g. Flanker, Foxbat, Foxhound etc.), while bomber names start with “B”/“BRAVO.” Propeller-driven planes are designated by monosyllabic words (e.g. “BEAR”) and jets by multisyllabic words (e.g. “BACKFIRE”). Helicopters and guided missiles are designated similarly, but the length of the codename is not defined.
The Russian Defense Ministry has placed an order for 76 FELONs, which are scheduled for delivery by 2028. Rosoboronexport hopes that the export version of the fighter aircraft (Su-57E) will draw interest from customers such as India, the People’s Republic of China, and Turkey. The revenue from export sales will be key for the Russian government to procure more Su-57s, which the Russian Aerospace Forces need to phase out older airframes such as the Su-27 and MiG-29 in the following decades.
