Andrew Shapiro, the assistant secretary of state for political-military affairs, told a news conference the U.S. administration did not anticipate any objections to the sale from Israel, traditionally wary of arms sales to nearby Arab countries.
"We think it will enhance regional security and stability rather than diminish it," Shapiro told a news conference.
The sale, which had been expected, includes 84 new Boeing F-15 aircraft and 70 upgrades of existing Saudi F-15s. It also includes 70 of Boeing's Apache attack helicopters and 36 of its AH-6M Little Birds.
In addition, the deal will include 72 Black Hawk helicopters built by Sikorsky Aircraft, a unit of United Technologies Corp..
