Araguari (P122) is a Amazonas-class offshore patrol vessel currently operated by the Brazilian Navy.

She was originally named San Fernando (CG52) while she was being 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 United Kingdom,[3] the Government of the Republic of Trinidad and Tobago (GORTT) cancelled the order in September 2010.

[5] San Fernando was built by BAE Systems Maritime in Glasgow and launched on 16 July 2010.

The ship was sold to the Brazilian Navy and renamed Araguari (P-122).
