Forbin (D620) is a large anti-air frigate of the French Navy, lead ship of the . Her first task is protecting aircraft carriers, capital ships or civilian ships from supersonic missile attacks; her complement of medium-range anti-air missiles allows her to support the defences of another ship under attack and avoid their saturation. She is also capable of monitoring and controlling operations carried out from the sea by friendly aircraft. Forbin is the sixth vessel of the French Navy named after the 17th century admiral Claude Forbin-Gardanne. Operations Building and fitting out Construction of Forbin began in Lorient on 8 April 2002. The hull was built in 14 sections by a variety of subcontractors of DCN, including several companies from Saint-Nazaire. Each section was high, and long. Forbin was laid down on 16 January 2004; the hull sections were transferred from Saint-Nazaire to Lorient on a barge tugged by Alcyon and assembled there from February 2004 to January 2005, finishing with the bow. The engines were delivered by FiatAvio in September. Forbin was launched on 10 March 2005, after part of the Scorff river was dredged to make it deep enough for her draught. She was towed out of her building dock by four tugboats at 16:15, taking advantage of the tide. On 28 October, Forbin entered dry dock and underwater equipment was installed, notably the sonar, propellers and rudders. Trials were held throughout 2006. Engine tests started on 10 May, and she sailed for sea trials on 29 June. Tuning of the combat management systems was particularly problematic, setting the completion of the ship off-schedule enough for her commissioning to be delayed by several months. In late January 2007, Forbin underwent new extensive trials at sea, successfully testing her combat systems in exercises against Super Étendard and Atlantique 2 aircraft. The PAAMS was tested in late May at the Centre d'Essais des Landes. From 12 to 17, Forbin sailed to Toulon, her new home port, where her combat, detection and weapon systems were further finetuned. Forbin fired an Aster 30 at the test range of the DGA on 25 November. First cruise Forbin left Toulon on 3 March 2009 for her first long cruise, visiting Morocco, the United States and Canada. She carried a Panther from Squadron 36F of the Aéronavale to validate her air installations. Forbin sailed to Casablanca, and then to Rio de Janeiro. She left Brazil
