U.
S. Military Aircraft Curtiss JN-4 JENNY Photo By S.H.A.A. |
|
Developed from the JN-2 via the JN-3, JN-4 appeared in July 1916 and retained the latter's unequal span wings. The type was sold to the UK and US Army. Production was initially slow, but after the USA's entry into the First World War in April 1917 the production rate accelerated enormously to yield vast numbers of aircraft. After the end of the First World War and in the face of severely restricted budgets, the aviation arm of the US Army decided to modernize its Jennies rather than buy new aircraft, and a program between 1918 and 1926 updated its aircraft and standardized them with a more powerful engine. The type was phased out of the military service in 1927, but remained in widespread civil use for many years to come as a utility and barnstorming plane |
