Extract from the book "US Army Airships 1908-1942" by James R. Shock...
The AC-1 non-rigid airship was originally called the Army Type MA, MA-1, or Military Airship N°.221. The airship was known by the Goodyear men who constructed it simply as the "military airship." The designation was later revised to "AC" to fit into the Goodyear Pony Blimp series of Types A, AA, AB and AC
The AC-1 was a radical departure from civil designs of the day, with enclosed control car mounted flush to the bottom of the envelope and internally mounted engines turning propellers through a drive shaft arrangement.
Length Overall = 169ft / 51.5 mtrs
Maximum Width = 50ft / 15.24mtrs
Height = 56ft / 17.1mtrs
Volume 180,000 cu ft / 5,100 cu mtrs
Delivered to Army: January 1922
The assembled model is 148mm long and 56mm high.
It is in two parts, there is a nominal 2.5mm diameter hole through the floor of the Control Car for a mounting rod or display stand.
1/350, 1/600 and 1/700 scale versions of AC-1 are also in my CLASSIC AIRSHIPS shop.
