The Blackburn RB1 Iris was the first Blackburn designed flying boat . RB stood for Reconnaissance Boat (German: Aufklärungsflugboot ). The design was based on the tender requirements 14/24 , with the first version still being made of wood. The three-stemmed biplane had ailerons on all four wings and was powered by three Condor III with pull propellers. The development and construction of the machine, which was given the marine serial number N185, dragged on over two years. After the first flight on June 19, 1926, the prototype was transferred to Felixstowe for testing at the Marine Aircraft Experimental Establishment .
In the following year the hull was converted to all-metal construction; there were also better engines . During the entire period of service with the RAF , improvements and modifications were made. In the Iris IV version z. B. drove the middle engine to a pressure screw.
Only a few copies of this long-range reconnaissance flying boat were built and the last were taken out of service around 1933. The successor model was the Blackburn RB 3A Perth .
