Junkers Ju 352 Herkules (Hercules)

The Junkers Ju 352 Herkules was a wooden version of the Ju 252 transport aircraft, itself developed in an attempt to replace the Ju 52/3m. The new aircraft was very similar to the Ju 252, with the same three engined layout and hydraulic loading ramp (Trapoklappe). The wooden wings were moved back, a new vertical tail was designed, and the semi-circular windows of the Ju 252 were replaced with square windows. Defensive firepower was provided by one 20mm MG 151/20 cannon mounted in an EDL 151 dorsal turret, while two 13mm MG 131 machine guns could be mounted in the cabin windows.

The V1 prototype made its maiden flight on 1 October 1943, followed quickly by the V2. Both were powered by three 1,000hp Bramo 323R-2 air-cooled radial engines, capable of providing 1,200hp when used with water-methanol injection. They were followed by ten A-0 pre-production (V3 to V12) and thirty three A-1 full production aircraft. Plans were in place to produce the B-1 and B-2, both of which would have been powered by 1,800hp BMW 801 radial engines.

The Ju 352 was used by I./KG 200 to drop agents and fly other special missions, and to the Grossraum-Transportgruppe, based at Tutow. The Ju 352's most dramatic mission came on the night of 26/27 April 1945, when one became the last aircraft to land at Gatow (Berlin) with reinforcements (twenty five rather unlucky sailors), before returning to base carrying wounded soldiers.
