The Timbira is a Brazilian Tupi Class submarine commissioned into the Brazilian Navy in 1996. The
Timbira is equipped with eight bow tubes fitted with a swim-out discharge system. 16 torpedoes are carried, eight in the tubes and eight ready for reloading. The Instituto de Pesquisas da Marhina (IPqM) the Naval Research Institute of the Brazilian Navy has designed an anti-submarine torpedo which can be carried on the
Timbira. The torpedoes have a range of 18 kilometres and speed of 45 knots. The 533 mm tubes are also capable of launching the Marconi Mark 24 Tigerfish Mod 1 or Mod 27 torpedo. IPqM has developed a range of weapons, naval control systems and electronic warfare systems to meet the operational requirements of the Brazilian Navy, including a range of acoustic-magnetic bottom and moored mines. The submarine's weapon control system is KAFS-A 10 control system supplied by Marconi S3I. The
Timbira is powered by four 12V 493 AZ80 GAA31L diesel engines developed by MTU, four Siemens alternators rated at 1.8 MW and a Siemens 3.4 MW motor. The propulsion system provides a surface speed of more than 10 knots and a submerged speed of 24 knots. Research Timbira
