After Greece received the first submarine with the Nordenfelt I , the Hohe Pforte ordered two larger submarines on January 23, 1886. The Nordenfelt III was launched on August 4, 1887 in the Des Vignes shipyard in England . 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. The armament consisted of two Nordenfelt mitrailleuses of 2 × 35 mm and two Schwartzkopff torpedoes . The torpedoes were 3.50 m long and 0.355 m in diameter. One weighed 157 kg, had a warhead of 18 kg and reached a speed of 10 knots (unit) (18.5 km / h).
After completion, the Nordenfelt III was dismantled, transported in individual parts to Istanbul and reassembled in the Imperial Shipyards . In 1889 after the assembly it was baptized after the heir to the throne Abdülmecid II. Abdülmecid . The sister ship was the Nordenfelt II , which was called Abdülhamid . The two ships were extremely unstable. The Abdülhamid almost sank when a torpedo was fired. It soon became apparent that the submarines were completely unusable. They remained largely unused until they were canceled in 1921.
