O 9 was an O 9-class patrol submarines of the Royal Netherlands Navy. The ship was built by Koninklijke Maatschappij De Schelde shipyard in Flushing.
Design
[edit]In 1927 a protruding Telefunken radiopeiler was installed on the O 9 that allowed the boat to receive long wave radio frequencies underwater.[2]
In February 1943 the O 9 was equipped with a fire control system that was developed by its commander Drijfhout van Hooff and manufactured by Cambridge Instrument Company Ltd.[3]
Service history
[edit]The submarine was ordered on 30 August 1921 and laid down in Flushing at the shipyard of Koninklijke Maatschappij De Schelde on 1 December 1923 or 23 September 1922. The launch took place on 7 April 1925. On 18 January 1926 the ship is commissioned in the Dutch navy.[4]
21 June 1926, O 9, together with O 11, Maarten Harpertszoon Tromp, Jacob van Heemskerck, Z 7 and Z 8, sailed from Den Helder to the Baltic Sea to visit the ports of Kiel, Göteborg and Trondheim.[4]
In 1929 O 9, O 10, Jacob van Heemskerck, Z 5, Z 6, made a trip to the Baltic Sea for exercises. The next year on 30 July 1930 O 9, O 10, Jacob van Heemskerck and Witte de With visited Antwerp.[4]
In 1931 O 9, O 10, O 8, Jacob van Heemskerck, Z 7 and Z 8, made again a trip to the Baltic Sea for exercises. She sailed for the Baltics again in 1936 with her sisters O 10, O 11 and Hertog Hendrik and Z 5. In 1939 O 9 together with her sisters O 10, O 11 were attached to the coastal division. They acted as the offensive part of Dutch coastal defense.[4]
From 9 to 11 May 1940 she and O 10 are on patrol off the coast of the Netherlands. During the patrol O 9 was attacked by German military airplanes. 12 May 1940 she, O 10 and a tugboat fled to the United Kingdom where they arrived on 15 May 1940.[4] While in the UK the O 9 was docked regularly for maintenance, which was needed because it was an old submarine.[5]
During the war she patrolled the English Channel and the Bay of Biscay. From August 1940 to March 1944 O 9 was attached to the 7th Training Flotilla in Rothesay and used as an ASDIC piggy boat. 1 December 1944 O 9 was decommissioned and September 1945 stricken. October 1946 she was sold for scrapping.[4]
