Northrop also remains in negotiations with Germany about its stalled 1.2 billion euro purchase of four Euro Hawks, which Northrop developed with Europe’s EADS based on the Global Hawk design. The plane has logged over 200 flight hours and just completed seven flights with various sensors.
Guerra said the company remained focused on working with both the U.S. and German systems to resolve any issues impeding additional sales.
Northrop is already under contract to build five Block 40 versions of the plane for NATO, and should complete a design review this year for those planes, Guerra said.
Guerra said he will travel to Japan next week to meet with officials there about a possible order of four aircraft, and Northrop officials are continuing to work with the U.S. government about a possible sale to South Korea.
Canada has also expressed interest in the Air Force version of the planes, while Norway and Australia have looked at the Navy version, called Triton, according to sources familiar with the program.
Singapore has also expressed interest, but may face a tougher climb getting approval by the U.S. government, they said.
Northrop has built over 40 of the aircraft for the U.S. Air Force and Navy, and lawmakers have urged the Air Force to finalize orders for three more of the Block 30 variant - a deal that could come later this year.
Potential foreign sales could add 20 or more orders in coming years, according to defense industry experts.
