The modification, in support of a U.S. foreign military sale agreement, is worth $80.8 million and is the first international sale of Raytheon's AN/AQS-22 Airborne Low Frequency product.
"ALFS is a key tenet of our naval strategy, providing us a robust, rapid and far-reaching anti-submarine warfare capability," said U.S. Navy Captain Jim Glass, program manager for the MH-60 helicopter. "Now with the sale to Australia, we are providing our airborne ASW sensor of choice to advance the capabilities of a valued, allied fleet."
ALFS is used to detect and track submarines for underwater communication and collection of environmental data.
Raytheon said it earlier received two contracts for the AN/AQS-22. The first was for its manufacture and integration for the U.S. Navy. The second was for spares and weapon replaceable assemblies for units already in use by the service. The two contracts were worth a combined total of $141.5 million.
