No aircraft existed at the outbreak of WW1 equipped with a gun of any sort. That would change by April of 1915. The opening months of WW1 saw radical changes in military aviation, the first weapons equipped on service aircraft, the birth of true aerial surveillance, and the first dogfights between two planes.
They key development in this early stage of the war was the fitting of a synchronisation gear, which allowed aircraft to fire forward facing guns without the risk of damaging their propeller. This allowed for the development of new aircraft like Moraine-Sauliner L and the Fokker E1 monoplanes, the first true combat aircraft.
Producing these videos is a hobby of mine. I have a passion for history, and personally own a large collection of books, journals and other texts, and endeavor to do as much research as possible. However if there are any mistakes, please don’t hesitate to reach out and correct anything 🙂
