"The Ultimate Stealth Ship"

 Following up on last night's "Just about every nation has secret missile platforms hidden in shipping containers"

When one thinks of a stealth ship, images of the Chinese Type 055 destroyer, the French La Fayette-class frigate, or Swedish Visby-class corvette come to mind. The use of material and technology to produce a smaller radar cross-section or to reduce sound and electronic emissions are all common attributes of what is commonly considered a stealth ship. Yet, if one was to ask what is the stealthiest ship in the U.S. Navy, the answer may prove surprising. It is not USS Zumwalt, the newest destroyer in the fleet. It is also not the most recent Virginia or Seawolf-class submarine, and it most assuredly is not one of the littoral combat ships. The ship that holds this title is not even a commissioned vessel in the U.S. Navy, or owned by the government, but leased from one of the largest ship operators in the world. MV Ocean Trader, chartered by the Military Sealift Command for the U.S. Special Operations Command, most assuredly holds this title.

One may remember back to early 2014 when articles began to appear about the Navy obtaining a “Big, Secretive Special Operations Mothership,” as reported by David Axe in War is Boring. The story went, “The U.S. Navy is quietly converting a 633-foot-long cargo ship into a secretive helicopter carrier with facilities for supporting a large contingent of Special Operations Forces and all their gear, including jet skis.” In 2016, pictures appeared of the ship while at the BAE Shipyard in Mobile, Alabama. Constructed in the Odense Steel Shipyard in 2011 for Maersk Line, MV Cragside is capable of speeds of up to 21 knots. Her design is a common one in Europe, derived from the Flensburger roll-on/roll-of ships. She is a near sister ship to the four Point-class roll-on/roll-off ships chartered by the United Kingdom Ministry of Defense in 2002. The ship’s configuration, when compared to photos of the vessel before conversion, indicate an addition aft of the main house without windows or ports. Forward of the house, two enclosed helicopter hangers are added with the addition of a large flying off platform indicated by the drop-down nets along the edges.

That picture of the ship in Mobile is the last available image and report of the vessel by an American source. A French news agency reported the arrival of the renamed MV Ocean Trader in the Mediterranean on May 16, 2016. According to Maritime Administration records, the ship was renamed on October 30, 2015 and remains on the rolls as a U.S. flagged merchant ship as of July 1, 2017, although a few of the sources identify the ship as Marshall Island flagged. Checks of various Automatic Identification Systems (AIS) has the ship in Gibraltar on May 14, 2017, Souda Bay, Crete on May 24, 2016, and Amsterdam on August 16, 2017. The ship does not currently show up on any active AIS systems. A search of the Navy’s Military Sealift Command records, including both their annual reports – which state all the vessels owned and under long-term charter to the Navy – and the U.S. Navy’s official sites, have no records of the ship....
