There is probably $4 billion or $5 billion worth of business out there that I was able to touch real quick," Swanson told a conference hosted by Credit Suisse. Raytheon and other big weapons makers are looking to foreign orders to help offset a reduction in projected US military spending over the next decade. Raytheon's Chief Financial Officer, Dave Wajsgras, told the conference that more than 30% of Raytheon's bookings in 2013 would come from international customers, with foreign orders accounting for the "high 20% range" of revenues. "Missile defense is something that is in demand in every place that I travel to," Swanson said at the conference, adding that Raytheon was talking with customers about how they could maximize their missile systems, rather than just buying components.
