The DH.4 first flew in August 1916 and it entered operational service in France on 6 March 1917 less than a year later. The majority were manufactured as general purpose two-seaters in the <a href="/wiki/United_States" title="United States">United States</a> for the American expeditionary forces in France, becoming the only American made plane to see combat in WW1. </p><p>Following the <a href="/wiki/Armistice_of_11_November_1918" title="Armistice of 11 November 1918">Armistice of 11 November 1918</a>, many DH.4s were sold to civil operators where it was found to be particularly useful as a <a href="/wiki/Mailplane" class="mw-redirect" title="Mailplane">mailplane</a>. Early commercial passenger airplane service in Europe was initiated with modified variants of the DH-4. War-surplus DH-4s became key aircraft in newly emerging air forces throughout the world.
