Rockwell U-9A Aero Commander

The Aero Commander was a light twin-engined aircraft by Aero Design and Engineering Company part of Rockwell International. The initial production version was the Aero Commander 520. Versions manufactured after 1967 are known as the Shrike Commander.

In military service, it was initially designated the L-26 though in 1962 this was changed to U-4 for the USAF and U-9 for the US Army.

One U-4B became a presidential transport aircraft for Dwight Eisenhower between 1956 and 1960. This was the smallest "Air Force One", and the first to wear the now-familiar blue-and-white livery.

As of 2004, Shrike Commanders still remain in service with the United States Coast Guard and United States Customs Service.
