Pfalz D.IIIa

The Pfalz D.IIIa was an improved Pfalz D.III with the 180hp Mercedes D.IIIa engine. It had a larger tailplane and rounder lower wingtips for increased efficiency. [6] Perhaps most importantly, the twin guns were moved to the fuselage deck where they could be more easily aimed and cleared in case of a jam, unlike the D.III in which the guns were buried in the fuselage.
