The $414 million deal buys 137 LRASMs, support equipment, systems engineering, logistics and training support, Lockheed Martin spokesman Joe Monaghen said in an email. LRASM has a published range of about 300 nautical miles, is jam resistant, and designed to locate targets with onboard sensors rather than relying on guidance from another source such as a drone’s sensors or another ship. The missile is also difficult to detect.
