FACILITY AND IS OUTSIDE THE PERIMETER FENCE 25X1
AT 0950Z.' IN ON, TWO PROBABLE MISSILE-RELATED RAILCARS
ARE ADJACENT TO THE SLBM HANDLING CRANE. IN PROBABLY UNRELATED
ACTIVITY, A STRUCTURE OF UNDETERMINED FUNCTION HAS BEEN PLACED
AROUND THE TOP OF THE TYPHOON UPPER RUDDER. THIS STRUCTURE WAS
FIRST OBSERVED AFTER THE SUBMARINE WAS REMOVED FROM THE LAUNCH
DOCK AT SHIPYARD 402.
(S/D) BY 1721Z, THE HOISTING MECHANISM OF THE HANDLING CRANE IS
POSITIONED OVER THE MISSILE BAY OF THE SUBMARINE. THE CRANE'S
BLOCK AND TACKLE HAS BEEN LOWERED OVER THE OPEN DOOR OF THE
STARBOARD MISSILE TUBE FORWARD OF THE SUBMARINE'S SAIL. THE

FACILITY PRIOR TO THE FIRST AT-SEA LAUNCH
OF THE SS-NX-20 FROM THE WHITE SEA

SUBMARINE TO THE LOADING FACILITY SUGGESTS FUTURE
MISSILE-RELATED ACTIVITY. HOWEVER, ALL 20 DEMI-BALLAST CANS
REMAIN ON THE QUAY AT SHIPYARD 402. IT IS LIKELY THAT SOME
BALLAST CANS WOULD BE LOADED ABOARD THE SUBMARINE PRIOR TO AN
ACTUAL MISSILE LOADING.
