Fd. 22 Gun

The **Fd. 22 Gun** is a series of battleship artillery pieces with a caliber of 22 Faden (or 400 mm). They form the main battery on the Kayfer-class Fast Battleships, Imperatrix Gundel class Battleships, the Feuerreiter-class Battlecruisers and the Tauläufer-class Battlecruisers. The first guns of this caliber were introduced in 1922. They were designed to replace the Fd. 19.5 Guns of previous generations.

In 1930, the license to build guns of this caliber was sold to Teressien for usage on their Haberer-class Monitors.

## Design

### Modell 1922

The basic model is the Modell 1922, a breech-loading, built-up gun with a barrel length of 45 calibers (or 18 meters). With breech, this gun weights 110 tons. The barrel can be elevated to +30 degrees and depressed to -4 degrees. It can lug an armor-piercing shell of one ton over a distance of 32 kilometers at a rate of fire of 1.5 shots per minute (or three shells in two minutes).

## Mounts

The Fd. 22 gun is available in triple mounts and in dual mounts, the former of which are used on the Imperatrix Gundel class Battleships, the latter of which are used on the Feuerreiter-class Battlecruisers and the Tauläufer-class Battlecruisers.

In 1926, the Imperial Army put single-mounted Fd. 22 Guns into service with the Fortress Artillery at certain strongholds, especially at the border shared with Ahua. Most remarkable is the Falk-Battery at Araznasted and its total of six weapons of this type.
