Lockheed Martin Sippican's MK39 Expendable Mobile ASW Training Target and Field Programmability System (EMATT) is an unmanned underwater vehicle used to simulate the acoustic and magnetic signatures of a submarine for anti-submarine warfare training. The latest generation MK 39 MOD 2 produces active emissions, passive discrete tones, broadband noise, and echo repeats that respond to to all U.S. active sonar and torpedo systems. The MK 2 has a maximum speed of 8 knots, operates down to 600 feet in depth, with an endurance of up to ten hours depending on speed.

EMATT can be air or surface launched. A version called SUBMATT can also be submarine-launched. Lockheed has produced over 12,000 EMATTs for the U.S. and other navies.  The U.S. Navy procured 9,900 MK 39 Mod 2s through Fiscal Year 2013.
