The demonstration was successful and appropriations were forthcoming for the first Coast Guard purchase of aircraft. The Coast Guard Commandant, Admiral Billard, obtained an appropriation of $162,000 for the purchase of five aircraft specifically designed for the Coast Guard.

And two UO-1s were upgraded to UO-4s. Two UO-4 were purchased. One was based at Coast Guard Air Station Ten Pound Island and one at Coast Guard Air Station Cape May which was commissioned in 1926.
