MK 39 Expendable Mobile Anti-Submarine Warfare Training Target (EMATT)
The MK 39 Expendable Mobile Anti-Submarine Training Target (EMATT) is an all-weather, lightweight, inexpensive and expendable Anti-Submarine training target used by air and surface anti-submarine warfare platforms. The EMATT can be used for both open ocean and on-range training at the Navy's undersea fleet training ranges.
The MK 39 Mod 2 EMATT, in production since Fiscal Year 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.
The Navy is developing a True Echo Repeater (TER) Capability that will enhance the MK 39ís ability to simulate quiet diesel-electric submarines.
Approximately 9,900 MK 39 Mod 2s have been procured through Fiscal Year 2013. The first units were delivered in Fiscal Year 2005.
