Design and build
The vessels are based on the Royal Navy's River-class patrol vessel, are 90m long, and have 80 man crews plus accommodation for 40 troops. They are designed to perform a range of Economic Exclusion Zone (EEZ) management, special operations and maritime law enforcement tasks.
The first vessel was named Port of Spain at her launch, at BAE Systems Surface Ships’ Portsmouth facility, on 18 November 2009.
The third was named San Fernando when launched on 16 July 2010 at Scotstoun on the River Clyde.
The Amazonas class were originally named as the Port of Spain class and built for the Trinidad and Tobago Coast Guard. Then, despite two of the vessels having been completed at the time and awaiting delivery, and with crew training ongoing in the UK, the Government of the Republic of Trinidad and Tobago (GORTT) 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, was then confirmed on 2 January 2012.
Amazonas was commissioned into the Brazilian Navy on 29 June in Portsmouth. During her one-month voyage to Brazil, she docked in the cities of Natal, Rio Grande do Norte and Salvador, Bahia in September, and was expected to arrive in Rio de Janeiro on 5 October.
