'''''O 1''''' was a Holland 7P patrol [[submarine]]  of the [[Royal Netherlands Navy]]. The ship was built by the De Schelde shipyard in [[Flushing, Netherlands|Flushing]] and was the first submarine in the Dutch navy. It had a diving depth of 25 metres.<ref name="dutchsubmarines">{{cite web |url= http://www.dutchsubmarines.com/boats/boat_o1.htm |title=Dutch Submarines: The submarine O 1 |first= |last= |work=dutchsubmarines.com |year=2012 |accessdate=19 July 2013}}</ref>

==Service history==
The [[Royal Netherlands Navy]] purchased the submarine O 1 mainly to gain experience in the use of the underwater weapons.<ref name="100jaaronderzeeboten5"/> The submarine was laid down in Flushing at the [[Damen Schelde Naval Shipbuilding|shipyard of De Schelde]] under the name of ''Luctor et Emergo'' on 1 June 1904, as it was not yet certain the Dutch navy would purchase the ship. The design came from the American company [[Holland Torpedo Boat Company]] The engineer Marly Hai was sent to the shipyard to assist in the construction of the submarine. The launch took place on 8 July 1905.<ref name="dutchsubmarines"/>

A series of trials and tests were held that were overseen by committee appointed by the Ministry of Defence. The committee was not satisfied after the first series of tests but after the second series of tests the ship was purchased by the navy for 430,000 Dutch [[guilder]]s.<ref name="dutchsubmarines"/>

On 21 December 1906 the ship was commissioned in the navy as ''Onderzeese boot 1'' (Submarine 1); it is uncertain at which point the ship was renamed to ''O 1''.<ref name="dutchsubmarines"/>

Since the O1 quickly proved its value during various exercises and one boat was not sufficient to base new tactics and strategies on, the [[Royal Netherlands Navy]] ordered five new submarines, which were put into service in the period 1911-1914: the O2 to O5 and the KI. The last boat was specially designed for the service in the Dutch East Indies.<ref name="100jaaronderzeeboten5">{{cite web|url=https://www.rdm-archief.nl/RDM-PB/DIV-2006A.pdf|title=100 jaar onderzeeboten |publisher=Royal Netherlands Navy|pages=4–5|work=www.rdm-archief.nl |date=| accessdate=7 May 2018}}</ref>

In 1907 Queen [[Wilhelmina of the Netherlands]] watched the submarine as it made a dive. On 27 March 1908 [[Duke Henry of Mecklenburg-Schwerin|Prince Henry]] made a visit to the ''O 1'' while moored in Nieuwediep in [[Den Helder]].<ref name="dutchsubmarines"/>

The ''O 1'' was present in [[Amsterdam]] in September 1910 when the Belgian King and Queen visited the city.
In 1914 the 160 pk OTTO petrol engine was replaced by a 200 pk M.A.N. diesel engine.
In 1920 the ''O 1'' was decommissioned and eventually scrapped.<ref name="dutchsubmarines"/>
