Germany's Neubaufahrzeuge V heavy tank "NbFz"

Photos

  • Neubaufahrzeuge-V

Design

There was a desire to have heavy tanks with the reforming German Army and development of the Neubaufahrzeuge (NbFz) (new construction vehicle) was done by Krupp and Rheinmetall. In 1934 - 1935 prototypes were ordered.

The vehicles were initially designated the PzKpfw V and PzKpfw VI. When they weren't selected for production those designations were used for the later Panther and Tiger.

Armament

Both the Neubaufahrzeuges had secondary turrets, one at the right front, and one at the left rear.

Production

  • Neubaufahrzeuge V "NbFz": 5
    • Production:
      • 1933: 3
      • 1934: 2 Prototypes
      • 1935: 3 Experimental Vehicles
    • Manufacturer: Krupp, Rheinmetall, Rheinmetall-Borsig
  • Neubaufahrzeuge VI "NbFz":

Variants

  • Neubaufahrzeuge V "NbFz", Model A: Had 7.5 cm gun for armament.
  • Neubaufahrzeuge VI "NbFz", Model B: Had 10.5 cm gun for armament. Had a aerial around the turret for the radio.

Usage

Two were destroyed in Norway in 1941 and the last one was destroyed in Romania against the Russians.
Three of the NbFzs were sent to Norway and one of these was destroyed.

Training

After Norway the remaining NbFzs were used in training.
