Donar (Thunder) KraftStrahlKanone

Contray to popular reports the KSK (Kraftstrahlkanone)  was NOT a crude laser weapon able to penetrate 100mm of armor. It was a crude phaser (PHASed Energy Rectifier) that ran off the Thule Triebwerk - as such, the Haunebu and Vril craft had to hover and divert high voltage energy from the EMG engines to ball cascade oscillators that flowed down to two charged barrels wrapped in precision tungsten spirals capable of absorbing a lot of heat. The power could be changed so it was a phaser weapon.

On the Haunebu I  the upside down looking tank turret is not -  close ups show piping running into two elongated 60mm guns that had shrouds over them.

The escape hatch is present because the gunner sat apart in the turret, but this matches NO German tank turret at all, not even the Kugelblitz which wasn't around in 1939 anyway. But because the KSK guns caused both vulnerability and instability, they were dropped in favor of MK installations in the Vril 7 Geist and Vril 8 Odin which had an operating Oberon automated system above the control tower.

The MK 108 30mm blowback autocannon was mounted in subsequent versions of Haunebu and Vril disks. It had been manufactured in Germany during the war by Rheinmetall-Borsig for use in aircraft. The cannon measured 1057 mm length and weighted 58 kg. Its rate of fire was of 650 rounds per minute with a muzzle velocity of 540 m/s. Because of its slow muzzle velocity the cannon was difficult to aim and its range too short. However it proved to be very effective, reliable and easy to manufacture.
