OVERVIEW:  The SA-10b GRUMBLE SAM (S-300PS) battalion is a mobile air defense unit using the S-300PM system.  It is intended to provide area defense against airborne threats at all altitudes.


DETAILS:  The SA-10b GRUMBLE SAM battalion is a mobile air defense unit intended for providing strategic area defense of fixed targets against airborne threats. An S-300PS unit consists of a 5N63S FLAP LID B I-band fire control system, a 5N66 CLAM SHELL 3D radar providing low level surveillance and tracking information and six launch vehicles.  At regimental and brigade level, a 36D6 (NATO reporting name TIN SHIELD) 3-D S-band surveillance radar was added. A typical engagement begins with detection by the TIN SHIELD or CLAM SHELL radar. Illumination and guidance duties are then handed off to the 5N63 FLAP LID radar which illuminates the target.   
 
After launch, an on-board inertial navigation system guides the missile until it is captured by FLAP LID A tracking-and-guidance system.  At this point, the command guidance system takes over, and directs the missile to its target.

The 5V55R missile has a 15 second preparation cycle before firing.  The battery can track up to 12 targets and engage up to 6 targets at once using a single FLAP LID B radar.  The battery can fire a missile every 3-5 seconds.
