Rotating ring mount HD 151

The HD 151 (hydraulic rotating ring mount 151) was developed for the Wehrmacht air force as a replacement for the LB 204 rotating tower (20 mm caliber), as this repeatedly caused difficulties. The HD 151 carries an MG 151 (caliber 15 mm) with left-hand feed in a glazed dome. The HD 151/1 differed from the HD 151 in its MG 151/20 (caliber 20 mm). To protect the shooter from enemy fire, the HD 151/1 is equipped with chest and stomach armor and an armored screen. The HD 151/2 is a defensive stand developed by Focke-Wulf , which later prevailed over the tall design of the HD 151/1 due to its flat and more aerodynamic shape. The towers were used on various types of aircraft. Tests for the use of the rotating ring mount took place in the Kriegsmarine.
Model development of the rotating ring mount:
- Rotating tower LB 204 (previous model)
- HD 151 for MG 151
- HD 151/1 for MG 151/20
- HD 151/2 for MG 151/20 (Focke-Wulf turret)
Using the rotating ring mounts:
- Blohm & Voss BV 138
- Blohm & Voss BV 222
- Focke-Wulf Fw 200
- Focke-Wulf Fw 261
- Junkers Ju 290
- Trials on various boats of the Kriegsmarine
