National Technical Systems Inc. recently completed electromagnetic interference testing on the U.S. Navy’s Long-Term Mine Reconnaissance System (LMRS). The testing satisfies the MIL-STD-461E standard for undesirable radio frequency transmissions that could interfere with the successful operation of other shipboard electronics. The test consists of a self-propelled, torpedo-shaped mine-reconnaissance unmanned underwater vehicle that’s launched from a submarine to canvass underwater areas. The testing is done while the system is operating in a worst-case mode. NTS is one of a handful of independent laboratories that has a shielded room large enough to accommodate the test.

The LMRS is a clandestine mine reconnaissance system that uses unmanned underwater vehicles launched from submarines to survey potential mine fields in support of amphibious operations, other battle group operations and for safe ship transit around mine waters. The testing was performed under contract with The Boeing Co.

“This program was critical to the success of this new surveillance system,” says Bill McGinnis, National Technical Systems CEO. “Hopefully our expertise made a useful contribution to the program and we’re pleased Boeing selected our group.”
