MV Hansa Stavanger is a German container ship, captured by Somali pirates on 4 April 2009. Around May 1, 2009, the USS Boxer (LHD-4) and a screen of German Navy warships assisted approximately 200 members of the German special police unit GSG-9 in approaching the hijacked ship. During the last phase of the operation, James Jones, the U.S. President's security advisor, withheld final approval for the operation out of concern for the safety of the 25 sailors aboard the vessel.
