been involved in counter-piracy operations off the Horn of Africa. The untraditional target set (i.e., small slow-moving or even static surface targets) can apparently be challenging for doppler radars designed to take on "high end" threats. However, according to Jane's International Defence Review: [The RNLN has] reported great success using tailored surface-search software for the APAR sets fitted to the De Zeven Provinciën-class frigates deployed on antipiracy roles. By sacrificing some of APAR's high-end antiaircraft warfare capabilities, which were deemed unnecessary for the antipiracy role, its performance and resolution were improved in the surface-search role. Export On 30 November 2017, Alion Canada submitted a proposal based on the De Zeven Provinciën class for the Canadian Single Class Surface Combatant Project. Damen Group, as builder of the De Zeven Provincien-class frigates, was part of Alion's team in this proposal. Replacement In 2020 it was announced that these intensively used ships will not be replaced as planned around 2025. The Royal Netherlands Navy and the German Navy will cooperate towards a joint platform design to replace both the s and De Zeven Provinciën-class frigates from 2030–2035 onwards.
