Dymaxion deployment unit

A Dymaxion deployment unit (DDU) or Dymaxion House, is a structure designed in 1940 by Buckminster Fuller consisting of a 20-foot circular hut constructed of corrugated steel looking much like a yurt or the top of a metal silo.

[1] The interior was insulated and finished with wallboard, portholes and a door.

The Army Signal Corps commissioned Fuller in 1942 to develop 200 units as quickly as possible.

The wartime shortage of steel resulted in the cancellation of further production.

[2] Historical aerial photos show at least 14 between the two large H-shaped buildings for a total of over 24 units at the base from 1947 to 1970.
