HNLMS Utrecht (D817) was a Friesland-class destroyer serving with the Royal Netherlands Navy from 1957 to 1980. Constructed at the KM de Schelde shipyard in Vlissingen, the vessel's keel was laid on 15 February 1954, and it was launched on 2 June 1956. The ship was officially commissioned into service on 1 October 1957. Named after the Dutch province of Utrecht, this was the eighteenth ship bearing the name. The Friesland-class destroyer measured approximately 130 meters in length with a displacement typical of the class, designed for fleet escort and patrol roles during the Cold War era. Notably, in 1959, Utrecht was equipped with eight torpedo tubes capable of firing the British MK 20E torpedo, enhancing its anti-ship capabilities. However, these torpedo tubes were later removed as the Dutch Navy transitioned to favor American torpedoes. Utrecht's service included notable engagement during the West New Guinea dispute in 1962, when it, alongside the frigate Evertsen, engaged proa’s and fast attack craft in the Battle of Arafura Sea. This event marked a significant moment in the vessel’s operational history, demonstrating its role in regional conflicts and naval patrol duties. The ship's radio call sign was "PAEY," reflecting its communication identifiers. After nearly 23 years of service, HNLMS Utrecht was decommissioned on 1 August 1980. Subsequently, it was sold to the Peruvian Navy and renamed Castilla, entering service there on 6 October 1980. The vessel continued to serve until it was decommissioned in 1990, marking the end of its maritime career. HNLMS Utrecht holds historical significance as part of the Cold War fleet of the Netherlands, participating in regional conflicts and exemplifying post-war naval design and operational roles.
