FS2004 - sUKHOI sU-15T - 'FLAGON-A' Developed to replace the Su-11 'Fishpot-C' interceptor during the 1960s, the Sukhoi Su-15 first appeared as a scaled-up version of the Su-9/Su- 11 family but powered by two engines and utilizing twin side inlets. These design changes freed up space in the new solid nose for a large radar, and powerful engines were installed to insure the Su-15 would fly considerably faster than any known Western aircraft of the time. The first production 'Flagon-A' models featured a mid-mounted cropped delta wing, swept tail surfaces, and a large bubble canopy placed aft well of the conical nose. Later models introduced a "kinked-delta" wing planform of greater span and a more aerodynamic ogival nose.
