The main source of the Su-35's head-on RCS is the inlets. The straight duct provides direct visibility for the entire face of the engine compressor. While this may be good aerodynamics, Bill Sweetman noted that "the inlet might have been designed to advertise the fighter's presence at the greatest possible range." Part of the solution was a high-performance, ferro-magnetic RAM for the compressor face and duct walls. This model was carried through a work of radar signature reduction of approximately of 25db with the application of a process developed in experimental way with the Berkut and later perfected in the turbines of the new version for the Su-35. This goes beyond the application of a new type of absorbent material of high performance with bigger capacity of durability when subjected to the high temperatures emitted by the turbines. The modified Su-35 also has a treated cockpit canopy which reflects radar waves, concealing the high RCS contribution from metal components in the cockpit. Beyond these changes, radar absorbent material of greater durability allied with the structural changes, mean that it is expected that the RCS of the aircraft will be equivalent of a F-16, that is, around 1m (Reduced RCS (b/w F-16 (about 1m^2).
