MK 39 Expendable Mobile Anti-Submarine Warfare Training Target (EMATT)

 
Description
The MK 39 Expendable Mobile Anti-Submarine Training Targets (EMATT) are used by air and surface ASW platforms for unrestricted open ocean as well as on-range training at the Navy's underwater Fleet training ranges.
 
Background
The MK 39 Mod 2 EMATT, in production since FY 2002, simulates diesel electric submarines by operating at various speed, depths, and headings. Acoustically, the MK 39 EMATT generates passive discrete tones, broadband noise, active emissions, and echo repeats to all U.S. active sonar and torpedo systems. The MK 39 also provides a detectable Magnetic Anomaly Detection (MAD) signature for air ASW training. A portable programmer allows for both mission uploads and software upgrades in addition to selectable, preprogrammed acoustic output levels and frequencies and dynamic scenarios.

Approximately 7,101 MK 39 Mod 2s have been procured through FY 2011. The first units were delivered FY 2005.
