ODD PAIR RADAR
COLORADA RADAR SITE, NICARAGUA (SWN/NOFORN)
1. SIGNIFICANCE: TWO ODD PAIR HEIGHT FINDER RADARS WERE
IDENTIFIED FOR THE FIRST TIME IN NICARAGUA. (SWN/NOFORN)
2. REMARKS: ON (AIRCRAFT) IMAGERY OF
TWO ODD PAIR RADARS AND ASSOCIATED SUPPORT VANS
WERE IDENTIFIED AT COLORADA RADAR SITE, 14 NM SOUTH OF
MANAGUA. ONE BAR LOCK RANGE AND AZIMUTH RADAR AND THREE
SUPPORT VANS REMAINED ON A HILLTOP SOUTH OF THE ODD PAIR
SINCE.THE AIR WARNING RADAR SITE WAS IDENTIFIED ON IMAGERY
OF BOTH OF THE RADAR SCREENS ON THE BAR LOCK
AND EACH OF THE SCREENS ON THE ODD PAIR WERE ORIENTED WEST,
PROBABLY INDICATING THEY WERE NOT OPERATING AT THE TIME OF
IMAGING. (SWN/NOFORN)
FIVE PYRAMIDAL TENTS (TWO ON GRAPHIC) WERE OBSERVED AT OR
NEAR THE SITE. PYRAMIDAL TENTS ARE NOT NORMALLY SEEN IN
NICARAGUA. TWO OF THE TENTS WERE ASSOCIATED WITH A THREE
POSITION PROBABLE ZPU-4 ANTIAIRCRAFT HEAVY MACHINEGUN SITE
IMMEDIATELY WEST OF THE ODD PAIR. OTHER PHYSICAL SECURITY
MEASURES OBSERVED,BUT NOT ON THE GRAPHIC INCLUDED NUMEROUS
FOXHOLE-TYPE POSITIONS AND AT LEAST SIX L-SHAPED TRENCHES.
(S/NOFORN)
ANALYST'S COMMENTS: FIRST DEPLOYED IN 1972, THE ODD PAIR
IS AN ADVANCED, SOVIET-MANUFACTURED HEIGHT FINDER RADAR
DEVELOPED FROM THE SIDE NET FAMILY. THE ODD PAIR IS
THOUGHT TO PROVIDE A BETTER ELECTRONICS COUNTER-COUNTER
MEASURES CAPABILITY THAN THE SIDE NET. THE DEPLOYMENT OF
ODD PAIR IN CONJUNCTION WITH THE BAR LOCK PROVIDES
NICARAGUA WITH AN EARLY WARNING/GROUND-CONTROLLED INTERCEPT
CAPABILITY FOR THE SOUTH/CENTRAL PACIFIC COASTAL REGION AS
WELL AS FOR THE MANAGUA AREA. (SWN/NOFORN)
