Ballistic missile defence
The Koninklijke Marine is investigating the use of these ships for the role of Ballistic Missile Defence (BMD). During tests carried out by HNLMS Tromp in the Pacific ocean near Hawaii, experimental modifications to the SMART-L to allow even longer range were proven (detailed in the Tromp article). A study by the Koninklijke Marine, the Netherlands Defence Material Organization, Thales Nederland, Raytheon Missile Systems, Johns Hopkins University Applied Physics Laboratory, and Lockheed Martin has been conducted to establish the feasibility of modifying the De Zeven Provinciën class to provide it the capability to intercept ballistic missiles. In particular, the study examined the feasibility of integrating the SM-3 Block IB missile with the SMART-L and APAR radars. The study concluded that - with certain modifications to the SMART-L and APAR, as well as to the ship's Combat Management System and the missile itself - BMD with the De Zeven Provinciën class could be achieved.[2]
A contract was awarded for the radar modification in June 2012.[3]
Modernizing
The De Zeven Provinciën class are very modern. The De Zeven Provinciën-class ships will get the new Smart-L mk2 radar that can detect ballistic missiles at a range of 2,000 km (1,200 mi). The Dutch minister promised also that the APAR radar will have a bigger range than 400 km (250 mi). This is because the Netherlands is the first country that is participating as an active missile shield for NATO.[citation needed]
In late 2011, the Ministry of Defence announced a modernization program to upgrade the SMART-L early-warning radar so that De Zeven Provinciën-class frigates can detect and track ballistic missiles at extended range. Although there are no plans to acquire the BDM-capable SM-3 surface-to-air missiles, De Zeven Provinciën-class frigates can be passed on the tracking and detection data to other sea-based or land-defense BMD assets, including the U.S. Navy’s warships, that can deal with a ballistic missile threat. This modernization program is scheduled for completion by late 2017 for the entire De Zeven Provinciën class.[4]
