Germany's Junkers Ju 252 transport, Junkers Ju 352 "Herkules" transport

Design

Junkers Ju 252

The Junkers Ju 252 was designed in 1939 intending it would be a replacement for the Junkers Ju 52.

It was similar with the three motors, but the rest was a new design. The Ju 252 was larger, faster, and could carry a larger load. It was constructed from metal but did not have the corrugated skin like the Ju 52.

The Ju 252 had a ventral loading hatch.

Junkers Ju 352

The Junkers Ju 352 Herkules was made from wood and steel tube construction to save on strategic materials. The Ju 352 was covered in fabric.

The BMW Bramo 323 engines were selected as they had a lower production priority. The BMWs would have 1,200 HP at takeoff with water-methanol boost.

Prototype

In September 1939 there were four Ju 252 prototypes under construction.

The Ju 352V1 prototype first flew in October 1943 / October 1, 1943.

Production

There was an initial order for 25 Ju 252A-1s placed. Only eleven of these were built as it was felt the Ju 252 would make demands on strategic materials.

  • Junkers Ju 252 Prototypes: 4
  • Junkers Ju 252: 11
  • Junkers Ju 352 Prototypes: 2
  • Junkers Ju 352A-0: 10
  • Junkers Ju 352A-1: 32, 33
  • Manufacturer: Junkers Flugzeug und Motorenwerke A.G.

Usage

Germany was the only user of the Ju 252 and Ju 352.

The Ju 252s were used on special duties, such as agent drops, and cargo transporter.

The Ju 352 entered service in 1944 and was also used for special duties and also glider towing, paratroop dropping, and transporting. There were also missions to carry spies and agents behind enemy lines.
