OVERVIEW:  The MM/SPG-70 aka RTN-10X "Orion" radar is a shipborne fire control radar operating in the NATO I-band (IEEE X-Band).

DETAILS:  The RTN-10X radar is a conical-scan fire control radar that is capable of guiding both guns and missiles. The system employs separate signal and data processing techniques to ensure a high-level protection from jamming and interference and to maintain accurate tracking of both high- and low-flying targets.  It has two operating channels: pulse mode for target search and continuous wave mode for target illumination. 


Specifications:

	Frequency:	 8-10 GHz (I-band (NATO))
	PRF:		 2000 pps
	Power: 		 200 kW (peak); ?? kW (average)
	Range:		+20  nm  vs. fighter-sized aircraft			
	Accuracy:		??  (range)
			
NOTES:  IOC 1972 (approx). It's small size and requirement for only one operator makes it suitable for installation on fast-attack craft upwards.. Widely exported as the RTN-10X.
