The Junkers A 32 was a mail plane built in prototype form in Germany in the late 1920s, and later developed as a prototype reconnaissance-bomber under the designation K 39.
The design was a conventional low-wing cantilever monoplane with fixed tailskid undercarriage.
Construction was metal throughout, with corrugated duralumin skin.
Three open cockpits were provided in tandem; the third seat intended from the outset to accommodate a tail gunner for a military version of the aircraft.
In fact, the militarised version developed in Sweden by AB Flygindustri featured a fourth crew position as well, for a bombardier.
This version featured twin machine guns built into the engine cowling, and a trainable machine gun for the tail gunner.
Only two A 32s were built, and the first prototype was destroyed in a crash on 2 November 1927 that killed Junkers engineer Karl Plauth.
The sole K 39 constructed may have been modified from the second prototype.
No sales of either the civil or military version ensued.
