What did the declassified documents reveal?

This declassified record from the F-B-I and U.S. Far East Air Forces offers an intelligence estimate of Chinese Communist Air Force strength during the Korean War. Issued on March nineteenth, nineteen-fifty-three, this document details the number and type of aircraft by airfield and unit location. This record was released to the public domain via The Black Vault, which can be found at documents2.theblackvault.com. The canonical F-B-I source for this kind of declassified material is vault.fbi.gov. The document opens with a memorandum from Headquarters, Far East Air Forces, dated March twenty-fifth, nineteen-fifty-three. Subject: Estimate of Air Strength of the Enemy Air Forces in China. To: See Distribution. One. Attached is D-slash-I, F-E-A-F’s estimate of air strength of the enemy air forces in China as of March thirteenth, nineteen-fifty-three. This supersedes the estimate dated September thirtieth, nineteen-fifty-two and is to be posted in accordance with applicable regulations. Two. As it is not possible to make an accurate count of aircraft strength of any particular unit, this estimate depicts the number of aircraft believed to be at a specific airfield, and does not attempt to assign a certain number of aircraft to the units accepted. Thus this estimate consists of two parts. Part I, aircraft strength by airfield, and Part II, a listing of identified air units and their probable location. By command of General Weyland. One Incl: (Two Parts) Est of Air Strength This is signed by Colonel T. K. R. M-C-G-E-E, U-S-A-F, Deputy for Intelligence. The distribution list includes various commands, including C-G, Fifth A-F; C-G, Twentieth A-F; C-G, S-A-D-F; C-G, Three-Hundred-Fifteenth A-D; C-G, F-E-A-L-O-G-F-O-R; C-G, Bombco; C-O, Six-Thousand-Twentieth Security Group; and C-O, Six-Thousand-Fourth Air Intelligence Service. Information copies were sent to C-slash-S U-S-A-F, Attention D-slash-I; C-I-N-C-F-E, J-Two; F-Y-F, G-Two; N-A-V-F-E, N-Two; C-G, S-A-C X-Ray. The document notes: The aircraft strength figures used in this estimate do not coincide with those given in Air Intelligence Study two-two, D-slash-I, U-S-A-F and O-N-I, Six-Hundred (R), January first, nineteen-fifty-three. The differences stem from the fact that D-slash-I, F-E-A-F bases his figures on estimated current unit strength rather than on T-O-and-E strength. The purpose of this estimate is to present the approximate generative or offensive air capability at any specific location or in a given area. The document then provides a summary of air strength by type of aircraft, listing "Total Air Forces," "Jet Fighter," "Piston Fighter," "Light Bomber," and "Ground Attack." It then lists these quantities by Military District, including North, Northeast, East, South and Central, and Southwest, as well as by specific airfields within those districts, such as Antung, Mukden, and Shihchiachuang. It specifies aircraft types like M-I-G-fifteen, M-I-G-nine, Y-A-K-nine, I-L-ten, and T-U-two. The…
