"This is a 33 percent increase over last year and I'm very optimistic that this positive trajectory will continue," said Lt. Gen. Charles Hooper, the head of the Defense Security Cooperation Agency, during a speech at the AUSA conference. "Our partners know a good thing when they see one."

Included in that total are $3.52 billion for cases funded by the State Department's Foreign Military Financing program; $4.42 billion for cases funded under Defense Department authorities; and $47.71 billion funded through pure FMS cases, per the State Department.

In FY17, the U.S. sold $41.93 billion in FMS deals, and the Pentagon has not been shy about hyping the final dollar total for this year. In July, Hooper said the department had already inked $46.9 billion in deals, and a Pentagon report released last year said that the U.S. had inked $54.45 billion through the end of August.
