The Commodore was the name given to the civilian flying boats which were purchased by the airline New York Rio Buenos Aires in 1928.

NYRBA placed an initial order of 6 Commodores for $150,000 each for it's airmail & passenger service to South America. With spare parts, the contract came to an even $1,000,000.

NYRBA later purchased an additional 6 Commodores for an additional $1,000,000.

The Commodores were designed to carry up to 32 passengers, the final arrangement provided for 22 passengers in two 8 passenger compartments and two drawing rooms each seating three. The crew would consist of pilot, copilot and a combination radio operator/steward. Ample space was also available for mail, express, radio gear and lavatory.

Fleet contracted for the services of Frederick J. Pike, interior decorator, who set a new standard in beauty and comfort in the plane's luxurious appointments. Each compartment had large picture windows and was panelled in a different pastel colour of waterproof fabric. The usual imitation leather seats were replaced by fabric upholstery. In every way the Commodores were the finest, largest transport planes available, and years ahead of their time.

The Admiral & Commodore had a unique tail construction.
