HNLMS Evertsen is one of four De Zeven Provinciën class air defence and command frigates in service with the Royal Netherlands Navy (Koninklijke Marine). Evertsen is the youngest of the four, having been completed in 2003 and commissioned in 2005. These ships superseded the two smaller Tromp class frigates, decommissioned in 1999 and 2001. Despite being classified by the Netherlands Navy as frigates, their displacement (6,050 tonnes), complement (202 + 30 aircrew), and role make them comparable to many destroyers. They are similar in these respects to the RAN’s planned Hobart-class Air Warfare Destroyers (AWD).  The Netherlands Navy also intends to use the De Zeven Provinciën class in a limited Ballistic Missile Defence (BMD) role, having recently awarded a contract for modification of the ships’ Thales SMART-L and APAR radars. According to an article in January’s Proceedings magazine, these modifications are expected to be complete by late 2017. It should be noted that the currently planned modifications only endow the class with the capability to detect and track ballistic missile threats, and do not provide for surface-to-air interceptor missiles.

Singapore’s Formidable class frigates are considered amongst the most advanced surface combatants in Southeast Asia. Built around a substantially modified version of the French La Fayette class, they feature an advanced stealth design incorporating a range of Radar Cross-Section (RCS) reduction features. The inclined planes of the hull and superstructures, concealment of typical ship’s equipment, low profile housings for armaments, and enclosed sensor mast are chief amongst these. The Formidable class armament includes: an Oto Melara 76mm Super Rapid naval gun, 8x RGM-84C Harpoon SSMs, and 4x 8-cell Sylver A50 VLS containing a mixture of Aster 15 and Aster 30 SAMs. The ships are also capable of firing EuroTorp A224/S Mod 3 torpedoes, and carry a Sikorsky S-70B naval helicopter with ASW equipment (they formerly operated Eurocopter AS-332M Super Pumas).
