The O-47 observation monoplane was one of the first aircraft build by North American, to U.S. Army specifications. It was relatively advanced when it was first introduced in 1934, with an all-metal body and retracting landing gears. It had a distinctive deep underbody with the observer's station. However, it was obsolete in 1941, and saw service mainly as a trainer and target tug.
