What a difference an engine makes! The
Airco DH9 had always struggled to perform its mission with a barely-adequate 230 Siddeley Puma engine. Replacing that with a 400hp Liberty V12 turned the
DH9a "Nine-Ack" into a winner, albeit one that only had impact in the last few months of the war. Liberty engines were delivered in much smaller numbers than projected, and though the first eighteen machines were delivered in June 1918, it was not until the end of August that the first squadron in France began combat missions. Though only a handful of squadrons received their DH9As before the armistice, the type served on for many years afterwards in a variety of roles.
This version of the DH9A features twin Lewis guns and short, DH9-style exhaust pipes.
A Single-Lewis version is also available,
and it has more scale options.
