Standard J-1

The Standard J-1 is a two-seat primary trainer developed from the earlier Sloan and Standard H-series aircraft designed by Charles Healey Day. When the U.S. entered WW I, the Army ordered the aircraft (then known as the SJ) produced as a supplement to the Curtiss Jenny then in production. At about the same time, Standard introduced an advanced version of the SJ called the JR.

The Army bought only six of the JR-series aircraft, but some of the JR’s features were incorporated into SJ production aircraft; the resulting version became known as the J-1.

Four companies–Standard, Dayton-Wright, Fisher Body and Wright-Martin–built 1,601 of the J-1s before production ended. Some 2,700 more J-1s on order were cancelled when the Armistice was signed. Hall-Scott engines were most commonly installed in the J-1, but some were equipped with Curtiss or Hispano-Suiza engines.

Similar in appearance to the JN-4, the J-1 was said to be more difficult to fly and never gained the popularity of the legendary Jenny.
