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

Last updated: 31 Aug 2021

Background
The MK 39 Mod 3 EMATT, in production since 2016, is the US Navy’s open ocean Anti-Submarine Warfare (ASW) Training Target. MK 39 Mod 3 EMATTs simulate the acoustic and dynamic characteristics of a submarine. Acoustically, the MK 39 EMATT generates passive discrete tones, broadband noise, active emissions, and echo repeats U.S. active sonar and torpedo systems. This allows the Navy ASW communities (surface, air and subsurface) to train their detection, tracking and weapon employment skills against a threat representative target. MK 39 Mod 3 EMATTs are launched from ASW aircraft via sonobuoy launchers, as well as from surface ships and range support craft. A portable target programmer allows for both mission uploads and software upgrades.  The EMATT also comes with selectable, preprogrammed acoustic output levels, frequencies, and dynamic scenarios.

More than 4700 MK 39 MOD 3 EMATTs have been procured since 2016. Over 30,000 MK 39 EMATTs have been procured since the EMATT was first introduced in the 1980s.
