Anti-aircraft defense was provided by a single 3.7 cm (1.5 in) SK C/30 anti-aircraft gun superfiring over the 10.5 cm gun and a pair of 2 cm (0.8 in) C/30 guns on the bridge wings. They carried six above-water 533 mm (21 in) torpedo tubes in two triple mounts and could also carry 30 mines (or 60 if the weather was good).

The objective was to construct two 7.6 m-diameter (25 ft) rail tunnels, 30 m (98 ft) apart, 50 km (31 miles) in length; a 4.8-metre-diameter (16 ft) service tunnel between the two main ones; pairs of 3.3 m (10 ft 10 in)-diameter cross-passages linking the rail tunnels to the service tunnel at 375 m (1,230 ft) spacing; piston relief ducts 2 m (6 ...
At the muzzle, these were 60 mm wide and had a maximum depth of 5 mm. Groove No 1 differed from the others and connected to a channel (rigole) in the chamber that guided the projectile to its proper position. [5] The 27 cm modèle 1864 transformé au modèle 1870 had the same inner configuration as the Canon de 27 C modèle 1870.

As built, the Type 24s mounted three 52-caliber 10.5 cm (4.1 in) SK C/28 [Note 1] guns, one forward and two aft of the superstructure, numbered one through three from bow to stern. [1] The mounts had a range of elevation from -10° to +30° and the guns fired 14.7-kilogram (32 lb) projectiles at a muzzle velocity of 925 m/s (3,030 ft/s). They ...
Ninety percent of construction costs were covered by federal funding, while 10 percent came from state funding. The tunnel consists of 32 tube sections, each 82 feet (25 m) wide and 42 feet (13 m) tall. The east and west approaches are 1,600 feet (490 m) and 3,200 feet (980 m) long, respectively. [8]
Derived from the World War I-era large torpedo boat SMS H145, [Note 1] the Type 23 torpedo boat was slightly larger, but had a similar armament and speed. [1] The first ship to be built, Möwe was slightly smaller than her sister ships and had an overall length of 87 meters (285 ft 5 in) and was 84.7 meters (277 ft 11 in) long at the waterline because she had a round, cruiser-style, stern ...
