Brazil Seeks Sub Fleet Combat System Upgrades
The Marinha do Brazil’s 4 diesel-electric Tupi Class submarines (1,440t U-209/1400 variant) and single 1,550t Tikuna Class (Improved Tupi) boat must suffice to patrol a very large ocean zone, along one of the world’s longest navigable coastlines. The SS Tupi [S30] was commissioned in 1989, the other 3 Tupi class subs were commissioned in 1996-1999, and the Improved Tupi Class, aka. S34 Tikuna, was commissioned into service in 2005. Both submarine classes were designed by HDW.
The Tupi and Tikuna boats are currently listed as being capable of launching indigenous Brazilian torpedoes, as well as the British BAE Stingray. Adding the Mk48 heavyweight torpedo would increase the subs’ attack punch, and upgrading the combat system would also offer an easy path to integration of anti-ship missiles like the Harpoon if the Brazilians wished. In the intervening years, other electronics have also advanced, and keeping the Tupi Class modern requires an upgrade. Hence the recent contracts with Lockheed Martin MS2.
Contracts & Key Developments
Dec 7/11: Lockheed Martin announces that the Brazilian Navy has successfully tested their integrated combat system aboard the Tupi Class SS Tapajo, as it detected, tracked and launched Mark 48 Mod 6AT torpedoes at targets during sea trials.
