Looks like:

"The U.S. Navy awarded Lockheed Martin (NYSE: LMT - News) a $17.5 million contract to upgrade existing anti-submarine warfare systems aboard the P-3C Orion aircraft to improve current acoustic capabilities and significantly reduce parts obsolescence.

Under the contract, Lockheed Martin will design, produce and install the new AN/USQ-78(V) Acoustic Subsystem for the P-3C Orion maritime surveillance aircraft. The contract includes upgrades and technical refreshes to software in addition to procurement of Acoustic Receiver Tech Refresh systems. By employing open architecture, the new system will allow future capability upgrades while improving reliability and maintainability that reduce overall cost."
