She served with the 5th U-boat Flotilla from 20 December 1941 for training and the 1st flotilla from 1 November 1942 for operations.
1st patrol
U-432 's first patrol was from Kiel in Germany. She headed for the Atlantic Ocean, via the gap separating the Faroe and Shetland Islands. She arrived at Brest in occupied France on 24 December.
2nd and 3rd patrols
For her second sortie, she barely got out of the Bay of Biscay.
Her third foray took her into the middle of the North Atlantic.
4th patrol and loss
Having left Brest on 27 April 1943, she, along with U-659, were both shadowing a southbound convoy on 5 May in preparation for an attack on the surface when the two U-boats collided. Both boats sank.[4]
Forty men went down with U-439; there were nine survivors.[1][3]
