She was completed at the Arsenal de Cherbourg in 1978 and served the French Navy until her 2001 decommissioning. From 2005 to 2009, Ouessant was employed as a training vessel to train Royal Malaysian Navy personnel who will operate the two French-built s planned for the Royal Malaysian Navy. Despite official statements in 2009 that Ouessant had been sold to Malaysia,[1] the position remained unclear.[2] Because of Ouessants role in the establishment of the Malaysian submarine forces, plans to return the vessel to Malaysia to serve as a museum ship were announced in July 2009.;[3] Ouessant was formally transferred to the Malaysian Government on 23 September 2011[4] to be transported to Klebang, Malacca to become a submarine museum.
