The Arend class (sometimes referred to as Valk class) was a class of two "opium hunters", meaning fast patrol boats built by the Maatschappij voor Scheeps- en Werktuigbouw Fijenoord in Rotterdam for service with the Government Navy. The class consisted of HNLMS Arend and HNLMS Valk.
Arend was commandeered by the Royal Netherlands Navy while still under construction as there was a shortage of available ships to protect the overseas Caribbean territories. She was therefore slightly modified in design and receive more armor plating. She was returned to the Gouvernements Marine in 1935 once had been completed and was able to take over the role of protecting the Dutch Caribbean.
Valk was employed as designed, as an opium hunter with the Government Navy after entering commission in 1930. During the Second World War, both ships served as patrol ships and seaplane tenders for PBY Catalina aircraft. After the fall of Java, both ships were scuttled by their crews as they were unable to escape to Ceylon or Australia.
