The U.S. Navy has a $50m cruise ship that could cost as much as $50,000 to operate, according to a new study.

The USS Bonhomme Richard is a 35-foot-long cruise ship designed to transport troops and equipment to and from overseas, but it has also been criticized by some for being too expensive for the Navy.

It was designed as a fast, cost-effective way to transport people to and fro and its low cost is a big factor in its appeal, the study by the Center for Strategic and International Studies (CSIS) found.

But the ship is now undergoing a $2.6bn refurbishment program and its fleet will need to be drastically upgraded, and the Bonhomie Richard has been mothballed, the CSIS study said.

“This will not be an easy project, but the Bonhamie Richard will be a major factor in ensuring that the U. S. Navy remains an effective and resilient force in the global fight against the threat of climate change,” the study said, using the acronym for the climate change acronym.

Although the U and the Chinese have been negotiating a new joint maritime code to reduce emissions of greenhouse gases, there is concern that the two countries could be unable to agree on new maritime agreements before the Paris climate summit in December, according the study.

The Bonhomieu Richard will remain in service until 2033, but at a cost of $150 million.

CSIS estimated that the Bonjamie Richard could cost more than $50 per passenger, or $30 per passenger crew, and $40 per passenger gross tonnage.

While it will have fewer passengers, the Bonamie Richard’s hull could be made lighter to make it more maneuverable, allowing it to carry more troops, the report said.

The Navy plans to buy the Bonemoune Richard in 2019 for about $75 million, according a Navy press release.

An earlier version of this article incorrectly identified the Bonme Richard as a Navy warship.

The Bonme is a naval patrol vessel, not a warship, and its current homeport is Norfolk, Virginia.
