Jacket, Flying, Mans, Nylon Twill. Sage Green, USAF 1511 Type N-3B. Mil-J-6279F (USAF) Size Medium. This jacket weighs about seven pounds. I believe this jacket is the Vietnam era according to the research I have done. Please conduct your own research. I do not know for certain the exact manufacturing date. The following is only provided as a source of reference. The N-3 Parka evolved through a series of specification changes, starting with the original 1945 issue. The first model of “Jacket, Aircrew, Heavy, Attached Hood, Type N-3″ was labeled Specification No. 3110 and had an olive green nylon outer, wolf fur rim on beaver lined hood, and was wool mouton insulated with a nylon inner lining. Around 1950, after the U. Air Force separated from the Army, the model became N-3A, the specification became MIL-J-6279 and the nylon outer was USAF blue in color. By 1958 the parka was known as the N-3B, under specification MIL-J-6279A and was grey in color. The specification continued to evolve from MIL-J-6279B and by the 1970s the color changed to Sage Green under MIL-J-6279F. By then the insulating layer was changed to a warmer, lighter polyester padding. Becoming “Jacket, Flying, Man’s Nylon Twill, Sage Green USAF 1511, Type N-3B” by the time of MIL-J-6279F in 1964.
