Development
Development
At the end of the Cold War, Soviet attack submarines were capable of moving at higher speed and diving at lower depth. Less ability to deal with them led to the need to develop a new type of torpedo. In 1989 a new torpedo project by Japan, G-RX4, was launched to make the necessary upgrades and start developing prototypes. By 1997 the new torpedo was approved and put into service and is called the Type 97. The torpedo is now equipping the JMSDF P-1 and P-3 ASW aircraft as well as filling the Mark 32 torpedo tubes on surface ships.
