Mk 50 Torpedo

The Mk 50 is a lightweigh torpedo developed to counter the the most advanced Soviet-era submarines that were both more quiet and diving deeper than previous generations. It is a very expensive lightweight torpedo that is both very vast and able to dive very deep. Due to the complex design the development took much longer than anticipated and due to the cost only a limited number was produced. Its conventional layout is very similar to the older Mk 46 that served as the basis for the Mk 50 design.
