Description: The MK 46 torpedo, first introduced in 1965, is a surface ship and aircraft-launched anti-submarine weapon. It is presently identified as the NATO standard and has been acquired by more than 25 countries. Various modifications, including improved acoustics, guidance and control upgrades, and countermeasure-detection capability have been introduced into the weapon.
The current version of the MK 46 is the dual-speed, active or active/passive MK 46 MOD 5A(S). The Navy introduced the MK 46 MOD 5A(SW) Service Life Extension Program (SLEP) torpedo in September 1996 which boasts improved counter-countermeasure performance, enhanced target acquisition, provides a bottom-avoidance preset, and improved maintainability and reliability. The MK 46 MOD 5A(SW) also serves as a payload for the Vertical Launch Anti-Submarine Rocket (ASROC) (VLA).
