Northrop Grumman [NOC] this week announced it’s Sperry Marine business unit has been selected by the Brazil navy to supply state-of-the-art navigation systems for four new NAPA 500-ton patrol vessels, with options for six additional vessels.

Sperry Marine will supply integrated bridge systems based on its new-generation VisionMaster FT(tm) navigation technology, including VisionMaster FT consoles, an electronic chart display and information system, navigation radars, heading and speed sensors, echosounder, steering control, mission data recorder and other subsystems. Sperry Marine will also supply MK 27F fiber-optic attitude and heading reference systems for the vessels under a separate contract.

“Sperry Marine’s selection to be the preferred supplier of navigation systems for this new class of patrol boats builds on our more than 30-year relationship with the Brazil navy,” Nolasco DaCunha, vice president of Northrop Grumman Sperry Marine, said in a statement.

Victor Cruz, senior manager, Latin America defense business, Northrop Grumman Sperry Marine, said, “The new ships will be equipped with a suite of state-of-the-art integrated navigation and ship control systems designed specifically to meet the unique space constraints and mission requirements of these coastal patrol vessels.”
