Fd. 19.5 Gun

The **Fd. 19.5 Gun** is a piece of battleship artillery used by the Imperial Navy on its older battleships, like the Bucks-class Fast Battleships, and older battlecruisers, like the Furtenland-class Battlecruisers. The breech-loading gun has a caliber of 19.5 Faden or 355 mm.

Currently, the Fd. 19.5 guns are planned to be superseded by the Fd. 22 Gun (40 cm gun) as battleship main artillery, relegating the Fd. 19.5 guns to coastal fortifications.

## History

In 1930, the Admiralty's Design Bureau revealed plans for what they termed as a 'pocket battleship', armed with Fd. 19.5 guns. Currently, no plans exist to build any such vessel, neither for service with the Imperial Navy nor for service with any foreign navy.

## Design

### Modell 18

The Modell 18 is the basic version of the Fd. 19.5 Gun, 50 calibers (17.75 meters) long and 82 tons heavy, including breech. Depending on the type of shell, the gun lugs a roundabout 650 kg shell over up to 34 kilometers.

### Modell 28

The Modell 28 is a simple upgrade of the Modell 18 with a new breech block, uniform rifling and new gun seats, all designed to improve accuracy.

## Mounts

The Fd. 19.5 Guns are available in single mounts, like they are used on the refitted Furtenland-class Battlecruisers, as well as triple mounts, like the are used on the Bucks-class Fast Battleships. In their mounts, the guns can be elevated to up to 30 degrees and depressed to -3 degrees.
