context_page_description: The River class is a class of offshore patrol vessels built primarily for the Royal Navy of the United Kingdom. A total of nine were built for the Royal Navy, four Batch 1 and five of the significantly different Batch 2. One Batch 1, which was the Falklands guard-ship, has been decommissioned and sold to the Royal Bahrain Naval Force.
  The three remaining Batch 1 ships perform fisheries security and border patrol tasks in UK waters. The five new Batch 2 ships provide overseas Forward Presence, performing maritime security duties and disaster relief operations, often supported by a Royal Fleet Auxiliary vessel.
  The Batch 1 ships of the class replaced the seven ships of the Island class and the two Castle-class patrol vessels.
  HTMS Krabi was the first of two ships adapting the River design for the Royal Thai Navy and built in Thailand. The three ships of the Amazonas-class corvette in service with the Brazilian Navy were a developed from the Batch 1 River-class design, and the Royal Navy’s Batch 2 ships are in turn based upon the Amazonas design.
context_section_description: Three vessels of the Amazonas-class corvette based on the River class were built by BAE in the United Kingdom. They were originally intended to be exported for use by the Trinidad and Tobago Defence Force; however, the Government of the Republic of Trinidad and Tobago cancelled the order in September 2010. In December 2011 it was reported that the Brazilian Navy were interested in buying the vessels, and possibly up to five additional vessels of the same design. The sale, for £133 million (compared to an original £150m), was then confirmed on 2 January 2012.
