Service history

The submarine was ordered on 1 June 1909 and 11 October that year the O 2 was laid down in Flushing at the shipyard of De Schelde. The launch took place on 30 January 1911. In the autumn of that year, trials were held and a depth of 40 meters was reached with no crew on board. On 1 December of that year the O 2 was commissioned in the Dutch navy.

In the autumn of 1913 the O 2 held a torpedo exercise with the HNLMS Jacob van Heemskerck.^[2]

During World War I the ship was based in Flushing.^[3]

When leaving the harbor of IJmuiden on 26 February 1919 the O 2 collided with the Dirk Sch 219, which had entered the harbor.^[4] After the collision both vessels sank. Submarine personnel escaped the ship through the tower hatch. The ships were later salvaged and the O 2 was repaired.^[3]

In 1930 the O 2 was decommissioned. In the early 1930s the ship served as a training vessel.^[3]
