cIA/PIx-65c29
A`cylindrically-shaped object (subsequer~~ly.evaluated es an?initiel
section of a possible submarine hull), approximately 15 feet acrgss its
visible diar'reter, was b~ser~e ~ otru~=fpm beneath _a a3~all weather'
concealment shed (approximately lon ) on buildimg?
way ~2. , Plarrow flat "platforr^~s ~ each approximately wide,_ were noted
attached along each side of the cylindrical, object. On the bas' of subseque
photo coverage of this yard, the cylindrical object seen in was
determined to ben possible submarine .hull section in the initial:stages of
assembly. No object wa?s observed protrudin~t from the other side. of the shed;
therefore,.the maximum length-overall (IAA) of the possible submarine hull
section noted at that time could have been no more than approximately 70 feet.
In order to plot the progress of the assembly of the submarine on way #2 thy'
distance from the forward (leading} edge of the possible submarine hull to?the
inboard center of the walkway connecting the craneway extensions over the water
acxoss ahe foot of the building way (see Figure 2) was measured on the first
three instances of coverage (the walkway remained fixed during this period). In-
method -of hull assembly. High vertical screens surrounded ~e shed and possible
hull on three sides; no screen was_ observed at the head of ~ay ~2,, At'-least-
six le.~ge additional vertical screen sections were noted stored at the~foot of
building way #2. Two weather shed roof sections were plac~d.on the floor of.the~
way ,just forward of the possible submarine-hull section. ~ -
marine-hull. section was noted approximately in the center of the~'longitudin6l
axis o~ the building way, indicating that tfihe Chinese used the 'send-loading"

protruding-from both ends of a weather/cone-ealment shed on building way ~. The

major axes of this object were a length of~pproximat~ly and width of
approximately 15 feet. The afi~ex edge of t~is?"flange" measured appro~imateLy
