Izdelie 270 is one completely new AAM .Completely new not by its design but by philosophy,so by combat tactics. It is obvious that its base is R-77 ,even has export R-77E parts but Izd 270 (R-47 ?) is much shorter. This AAM is developed for long term close in combat where its Time of aerodynamic stability and controlability or Guided flight time is 100sec. Izd 270 has multiple aero and gasdynamic control surfaces,from those famous lattice stabilisers via TVC-nozzle to the mini boosters on the sides of the body / maybe the centre of the mass/ .That boosters will can be used for sharp 180° turn immediately after launch and for the engaging of enemy fighter flying in the rear hemisphere of Su-57.Also they can be used for, if needed for multiple sharp turns .
Blue lines on the pic shows us somethnig very interesting ,astonishing....Those holes on the missile's body are for the laser proximity fuse transmit /receive antennas by the way.
