         The Airco D.H.9a 
         biplane bomber was an enlarged version of the D.H.9 with much needed 
         improvements. It was equipped with the more efficient American Liberty 
         engine, had a nose mounted radiator and even featured a spare tire 
         mounted under the fuselage. Although a bit shorter than the D.H.9, its 
         larger wings provided more lift for carrying heavier payloads. The 
         D.H.9a entered service too late to have much of an impact on the 
         outcome of the war.
