The Clément-Bayard No.1 was a French military airship of 1908 developed by automobile manufacturer Clément-Bayard in response to a French Army decision of that year to commence airship operations. The firm contracted Astra to build the envelope while it built the gondola and engines itself. The envelope's distinctive design featured four large lobes at the aft end intended to provide directional stability. Testing commenced on 28 October with Henry Kapferer at the controls.
Made by Clément-Bayard.
