Ottoman torpedo gunboat Peleng-i Derya

Peleng-i Derya was an Ottoman gunboat that was torpedoed by HMS E11 in shallow water off Istanbul, Ottoman Empire on 23 May 1915.

Construction
Peleng-i Derya was laid down in 1889 and launched and completed the following year at the Schiffswerft Germania AG shipyard in Kiel, Germany as part of the Peleng-i Deryâ-class gunboat alongside her sister ship Nimet. The ship was 75.5 m long, had a beam of 8.5 m and had a depth of 2.9 m. She was assessed at and had two triple expansion engines driving two screw propellers. The ship could generate 4700 ihp with a speed of 18 kn. She conducted her sea trials on 16 May 1896 and had an accidental boiler explosion on 22 May at Eckernförde, Germany.

Early career
Peleng-i Derya was bought by the Ottoman Navy in September 1896, but the six year old ship had not been equipped yet with any armaments. She was brought to a shipyard in Istanbul to be refitted with her armaments consisting of two 120 mm quick-firing (QF) Krupp (K) guns, two 90 mm QF K guns, three 75 mm QF K guns, four 47 mm QF Nordenfelt (N) guns, three machine guns (1906) and three 355 mm SK torpedo tubes. As time went on, her condition worsened and she was decommissioned in 1913 before returning to service at the start of the First World War in September 1914.

Sinking
Peleng-i Derya was anchored in shallow water near Bakırköy Bay at Istanbul on 23 May 1915 when the British submarine HMS E11 torpedoed her without warning. The ship capsized and sank with the loss of two crew, and her wreck was scrapped in 1920.

Wreck
The wreck of Peleng-i Derya was broken up in 1920 with some parts still being present to this day.
