The Donnet-Denhaut D.D.2 was a successful response to the call by Aviation Maritime for an armed, radio-carrying flying boat, capable of carrying a pair of bombs for use against submarines. It was quite successful and 401 were built.

The US Navy purchased some DD.2s, but as they were getting old by 1918, they were mostly used for training. Instead DD.8's and DD.9's were used for combat missions.[1]

It carried a wireless transmitter and it was used for maritime and anti-submarine patrol in the Atlantic, Mediterranean, and North Sea.[3]
