S30 Tupi

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 S30 Tupi 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 contract with Lockheed Martin MS2…
