The AN/TRN-30 benefits all U.S. Armed Forces by supplying a Non-Directional Radio Beacon for aircraft to navigate. The primary goal of the project is to extend its useful life for another 15 years. A secondary objective is to enhance the reliability and serviceability of the unit. By using current, more reliable technology and commercial-off-the-shelf (COTS) parts, the EMPF is able to reduce the overall cost and weight of the AN/TRN-30 and ensure that the customer is no longer tied to a sole supplier.<a href="beacon0106.html">[Full Article]</a> </div> <hr align="left"> </li> <li> <div align="left"><span class="style2"><a href="boot0106.html">Boot Camp</a></span><br> <span class="big style1"><strong>W</strong></span>ith the rapid changes in technology that engineers and technicians face, keeping up with the latest process methods, packaging changes, business goals, time to market, and scheduling, can become a daunting task.
