The Brazilian Navy has signed a $186m deal with BAE Systems for the purchase of three offshore patrol vessels (OPVs) as part of the navy’s Prosuper fleet modernisation programme.

Under the terms of the deal, BAE will supply three already-built 90m-long, 2,200t OPVs as well as provide manufacturing licences to the Brazilian Navy.

The contract includes an additional £13m for training and support by BAE including an option to locally build another five OPVs.

The vessel feature a helicopter flight deck, 30mm and 25mm cannons, can cruise at a speed of 25 knots when fully loaded and are capable of carrying a crew of 70, with additional accommodation for 50 troops or passengers.

Two vessels are scheduled for delivery to the Brazilian Navy in June and December 2012, while the third vessel will be delivered in 2013.

BAE had built the three OPVs for the Trinidad and Tobago Coast Guard to perform intercepting and emergency relief operations in the Caribbean region.

The deal, signed in 2007 and supported by the UK Government, was cancelled in September 2010 due to delays relating to delivery timelines.

The Brazilian Navy fleet modernisation programme also includes the procurement of five additional ocean patrol vessels, five frigate-class boats and one support ship.

The frigates and a logistics ship are currently under construction, while the submarine fleet is being built with assistance from France.

The UK Royal Navy previously offered to sell its Type 22 frigates as a temporary defence measure, but the offer was rejected by Brazil.
