The Argo was a two-place open cockpit sport-trainer biplane seating two in tandem and was powered with the new 7-cylinder Hess “Warrior” engine. The type certificate number (ATC 178) for the Alliance Argo was issued in July of 1929 and it was manufactured by the Alliance Aircraft Corp. in Alliance, Ohio.
The prototype Argo was shown at the Detroit Air Show for 1929 and soon was in production. It was well received in flying circles all over the country, but the oncoming depression was hard felt at Alliance Aircraft. In all, some twenty of the Argo Sport-Trainer were built
After the prototype, N3601, 19 or 20 were manufactured (priced at $4,500) before the type became the Warrior line in 1930.
By 2012, there were two survivors, with 1929 Argo N596K (cn 106) preserved at the Ohio History Center.
