PRF:			 350 Hz	
Range Resolution:	 1000 meters (range), 1 degree (azimuth) 				
On/Off time:		unknown
Deploy/Stow Time	N/A
Max Range:		230 nm




 
NOTES: IOC 1959. The radar family started with the AN/FPS-3 in 1950.  By the late 1950s, this radar dominated the US radar defense network, with deployment continuing into the early 1960s.
