By Dialogo January 12, 2012 The Brazilian Navy’s Naval Engineering Directorate has signed a contractual addendum with the Brazilian shipbuilder EISA for the construction of another 500-ton Macaé-class patrol boat. The Macaé class is intended for guarding Brazilian territorial waters, the Navy explained in a statement. These vessels are used for guarding and defending the coast, coastal maritime areas, and oil exploration and pumping platforms at sea. At the same time, they contribute to the missions of fighting drug trafficking, smuggling, and crimes against the marine environment, among others. The decision to choose a private domestic shipbuilder fits into the administration’s policy of incentives for naval construction and job creation, as well as responding to the need to increase the capacities of and strengthen the military-technology industrial sector. The contract signed with EISA, which includes a total of five vessels, foresees the delivery of the first boat in December 2012, with another every six months after that.
