US State Department approved a possible sale of lightweight torpedoes and related equipment to Norway, the Pentagon said Wednesday.

The estimated cost is $162.1 million, the Defense Security Cooperation Agency said in a statement.

"The proposed sale will improve Norway’s capability to meet current and future threats and increase its interoperability with the United States and other NATO members," it added.

The principal contractor will be RTX Corporation, located in Arlington, Virginia.

The agency delivered the required certification notifying Congress of this possible sale on Wednesday.
