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.
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 prototype was constructed from the second prototype A.32.
No sales of either the civil or military version ensued.
