History

Designed by Igor Sikorsky and built by the Russo-Baltic Wagon Factory (Russo-Balt), the Ilya Muromets conducted the first organised strategic bombing campaign in history during WWI. A fleet of these aircraft carried out hundreds of raids on German and Austro-Hungarian targets between 1914 and 1917.

Variants

Series B through G with progressively more powerful engines and improved capability; some later variants carried 400–800 kg of bombs.

Where you'll see it

Served exclusively with the Russian Imperial Air Force's Eskadra Vozdushnykh Korablei (Squadron of Flying Ships); phased out after the 1917 Revolution.
