When the U S Army Air Service AC-1 first flew in 1922 it was designed for use with hydrogen. At the end of that year however, the Army adopted a policy of using helium throughout it's fleet of airships. Whilst obviously being much safer to use than hydrogen, helium has only about 93% of the lifting capacity of hydrogen. This shortfall was a good part of the reason why AC-1 never achieved it's full potential and from as early as 1923 the Air Service proposed changing AC-1's envelope for a larger one. It was not until 1927 however, that AC-1's control car was mated to the more efficient TC-type envelope. The result was treated as a new member of the fleet and was given the designation "TC-12-264".
First flew: 1927
Volume: 200,600 cu ft ( 5,680 cu mtrs)
Length: 196 ft ( 59.74 mtrs)
Diameter: 44.5 ft (13.6 mtrs)
The TC-12-264 was not among the Army airships turned over to the U.S. Navy in 1937. Sadly it was scrapped.
The model is 171mm long and 53mm high.
It is a one-piece print, the Control Car window openings are large enough to allow the loose powder to be cleared away after printing.
There is a nominal 2.5mm diameter hole through the floor of the Control Car for a mounting rod or display stand.
