HNLMS Hydra (A854)

HNLMS Hydra (A854) is a diving support vessel of the Royal Netherlands Navy.

History
Hydra was laid down on 11 June 1992 at Scheepswerf Visser in Den Helder (now part of the Damen Group) as the last of four new diving support vessel. She was launched later that year on 11 September 1992 and commissioned on 20 November 1992.

During a refit in 1997, Hydra received a 10.5 m extension in the mid-section and a new bow thruster among other things. The lengthening increased the displacement from 223 t to 340 t.

It is expected that Hydra will reach the end of her lifecycle in 2026/27.
