Nordenfelt II or Abdülhamid was the first submarine of the Ottoman Navy . It was the thirdsubmarinedesignedby the English engineer George William Garrett and the second built by the Swedish industrialist Thorsten Nordenfelt .

history

After Greece received the first submarine with the Nordenfelt I , the Hohe Pforte ordered two larger submarines on January 23, 1886. The Nordenfelt II was launched on September 6, 1886 in the Barrow Shipbuilding Company in England . Later she was to Sultan II. Abdulhamid Abdulhamid called. The sister ship was the Nordenfelt III , which was later christened Abdülmecid . The ship was powered by a 250 HP single-cylinder steam engine, which was fed by a steam boiler from the Des Vignes company from Chertsey . It had two steam storage tanks for underwater travel . Excess steam could be stored here in the surface, which could be used for the drive in the submerged condition.

After completion, the Nordenfelt II was dismantled, transported in individual parts to Istanbul and reassembled in the Imperial Shipyards . The first test drives began on February 5, 1887. The specially traveled designer George William Garrett acted as captain. At first, you could successfully complete a few dives, but they only lasted 20 seconds. In spring 1888 it was possible to fire a torpedo while submerged . The Abdülhamid was the first submarine with which this was possible. However, the ship was extremely unstable. It almost sank when the torpedo was fired. It soon became apparent that the submarine was completely unusable, and when it almost sank after a ship passed close by, the crew refused to go back on board and no new volunteers were found. Garrett had to flee to avoid arrest.
