Delfin (Дельфин, lit. ’Dolphin’) was one of the first combat-capable submarines in history. She was commissioned in 1903 and decommissioned in 1917, having served during World War I.
I’ve modeled this funny looking submarine, trying to make 3d printing possible and as easy as possible with minimal supports. Some thin details are enlarged and strengthened.
Delfin was designed by Naval architect Senior Assistant Ivan Grigoryevich Bubnov, Lieutenant M.N. Beklemishev and Lieutenant I.S. Goryunov of the Construction Commission for Submarines (later the Rubin Design Bureau). The design was of a single-hull type submarine with saddle tanks whose outer plating was covered with teak to prevent damage in the case of grounding.[1] She was ordered in July 1901[1] laid down by Baltic Works at St. Petersburg, launched in 1902, and entered service in 1903, training officers and sailors. Initially the vessel was classed as a torpedo boat and only given a number instead of a name.
Delfin displaced 113 tons surfaced and 126 tons submerged. She was 19.6 metres (64 ft) long with a beam of 3.3 metres (11 ft) and a draught of 2.9 metres (9 ft 6 in). The submarine was powered by one gasoline/electric motor that created 300 bhp and 120 hp respectively that drove one shaft. This gave Delfin a speed of 9 knots (17 km/h; 10 mph) surfaced and 4.5 knots (8.3 km/h; 5.2 mph) submerged. The ship was crewed by 22 men, including officers.
Delfin‘s main armament was two external 15 in (380 mm) torpedoes in Drzewiecki drop collars. The boat was also equipped with one machine gun.
One piece hi-rez STL file for 3d printing the Delfin is below. There is a multi-piece STL package to enable you print a better looking sub with moving control surfaces, propeller, separate torpidos etc. You can dowload that package by clicking here. Thank you for your support.
