Wing loading
In aerodynamics, wing loading is the loaded weight of the aircraft divided by the area of the wing. The faster an aircraft flies, the more lift is produced by each unit area of wing, so a smaller wing can carry the same weight in level flight, operating at a higher wing loading. Correspondingly,...

The full designation of entire weapon complex (aircraft, radar, missiles) was Tu-128S-4. In the Western sources, but not in Soviet, often the more precise designation of this version is mentioned as either Tu-28P or Tu-128P.

The full designation of entire weapon complex was Tu-128S-4M. It contained a new RP-SM Smerch-M radar, and new missile set: R-4RM plus R-4TM.
