OVERVIEW:  The PIKE JAW aka Arktika-M MG-200 aka "Leningrad"  is an active submarine attack sonar operating in the 13-16KHz frequency.

DETAILS:  PIKE JAW was the first Soviet submarine sonar with the capability of calculating a torpedo targeting solution without using the periscope.  It can generate a target solution on a single target, while maintaining positional information on two targets.  Unlike contemporary western systems, the PIKE JAW could program torpedoes to turn through two gyro angles in sequence, increasing the hit probability despite errors in the target range estimate. 

Specifications:

Range:	2.0 nm
	
			
NOTES:  IOC 1958 (approx.).  Reportedly the first Russian sonar capable of auto tracking.
