OVERVIEW: The KNIFE REST B aka P-10 aka "Volga A" is a 2-D early warning and acquisition air search radar operating in the NATO "A" band. 

DETAILS: The P-10 has several improvements over the earlier KNIFE REST A, including improved resolution, sensitivity and improved electronic counter-countermeasures provisions. The system was made more mobile by fitting the main antenna array on a telescopic mast mounted on the command vehicle.
 A further improved version, KNIFE REST C, was also deployed. Both B and C models are associated with the SA-2 `Guideline' surface-to-air missile.

NOTES: IOC  1952.  The P-10 is a direct derivative of the Knife Rest A and was itself replaced by the  P-12 radar in 1956.  A navalised version was fitted to the `Sverdlov' class cruisers. The radar has been significantly updated for use against stealth aircraft.
