A CONTINUING ANALYSIS IS BEING MADE BY NPIC RELATIVE TO THE VARIOUS
TYPES OF SA-2 MISSILE CANISTERS OBSERVED ON PHOTOGRAPHY OVER NORTH

ARE BEING UTILIZED, BOTH OF WHICH HAVE. BEEN OBSERVED AT THE PHUC CAT
SAM SUPPORT FACILITY (REF. A). ONE OF THESE CANISTERS 25X1
IS THE CONVENTIONAL MOD I/II CANISTER WITH THE DISTINGUISHING FEATURES

ON THE FLANGED COLLAR NEAR THE REAR.OF THE CANISTER. THE SEC
CANISTER TYPE OBSERVED AT PHUC CAT DIFFERS FROM THE CONVENTIO
I/II PRIMARILY IN THE ABSENCE OF THE FORWARD-MOST SUPPORT RIB
THE ABSENCE OF THIS RIB
GIVES THIS CANISTER THE GENERAL APPEARANCE OF THE MOD III SA-2
CANISTER. HOWEVER, THE OTHER DISTINGUISHING FEATURES OF THE
ARE NOT DISCERNIBLE, I.E., THE CANISTER COVER DISASSEMBLY AT T
REAR OF THE FLANGED COLLAR, THE FOUR LINEAR CHANNELS ALONG THE
MID-PORTION OF THE CANISTER BODY AND A SLIGHTLY INCREASED DIM
ALONG THE FORWARD
A REVIEW OF SA-2 CANISTERS PREVIOUSLY STORED AT THE GIA

PHOTOGRAPHY REF B). THESE CANISTERS APPEAR T
IDENTICAL TO THE CONVENTIONAL MOD I/II CANISTER WITH THE EXCEP
OF THE ABSENCE OF THE FORWARD-MOST RIB. THIS IS THE SAME MOST
UISHING FEATURE OBSERVED ON THE PROBABLE MOD III CANISTERS IN
AT PHUC CAT. ALL OTHER FEATURES OF THESE CANISTERS AT GIA THU
ARE INDENTICAL TO THE CONVENTIONAL MOD I/II.
IT IS THEREFORE POSSIBLE THAT MOD I/II SA-2 MISSILES HAVE
BEEN SHI IETNAM IN BOTH TYPES OF CANISTERS SINCE
AT LEAST FURTHER ANALYSIS WILL CONTINUE WHEN GO
INTERPRETABLE A HY BECOMES AVAILABLE OF THE PROBABLE MO
CANISTERS AT PHUC CAT AND MAY REVEAL THESE CANISTERS TO BE NOT
THAT MODIFIED MOD I/II CANISTERS. THIS WILL THEN CONFIRM THE
OF TWO DIFFERENT TYPES OF SA-2 MOD I/II MISSILE CANISTERS.
