Aircraft History
Built by Commonwealth Aircraft Corporation (CAC). Constructor Number 103. During September 1940 delivered to the Royal Australian Air Force (RAAF) as CA-5 Wirraway serial number A20-103.

Wartime History
Assigned to No. 4 Squadron code D. On the left side of the nose was painted "Ugh!" with a character wearing a derby hat with "A. R. P." and a fork. On the left side of the nose was a scoreboard with three bomb markings indicating missions flown and a single Japanese rising sun flag indicating the aerial victory claim on December 26, 1942.

During early 1942, operated from Canberra Airfield (Fairburn). In early November 1942 flown northward to 12 Mile Drome (Berry) near Port Moresby.

On December 22, 1942 took off from from 12 Mile Drome (Berry) near Port Moresby and flew four sorties, two piloted by P/O Ranson and two by F/O Utber. The first two were reconnaissance over Buna and two artillery observation and gun spotting over Buna.

On December 26, 1942 took off from 12 Mile Drome (Berry) near Port Moresby piloted by P/O John S. Archer, 409285 with observer Sgt J. L. Convulsion on a tactical reconnaissance over the north coast of New Guinea searching for Japanese barges at the mouth of the Kumusi River then southward to Gona. Next, Archer made a single strafing pass against the shipwreck of the Ayutosen Maru. Pulling up to make another run, Archer spotted another plane approaching 1,000' below and incorrectly identified it as a Japanese "Zero". In fact, this was Ki-43-I Oscar pilot W/O Tadashi Yoshitake. Taking advantage of their higher altitude, Archer dived down onto fighter firing a long burst with his two machine guns and as he pulled away saw the enemy plane crash into the sea and explode. This was the only time a Wirraway made a confirmed kill against an enemy fighter.

Afterwards, Archer earned the American Silver Star from U.S. Army Air Force (USAAF) Brigadier General Ennis Whitehead, commanding general of Allied Air Forces in New Guinea. Later, Archer stated that he had acted on impulse and was lucky to get in an effective first burst.

On October 16, 1944 at 1:00pm while Wirraway A20-80 was taxing, it accidentally collided with this plane causing damage. Afterwards, this Wirraway was withdrawn from service.
