Third, U.S. numbers are shaky. Senior Air Force officers have stated that the service can afford only 48 JSFs per year rather than the 80 that the current program envisions, unless it gets more topline funding in the defense budget. The Navy and Marine Corps told the Government Accountability Office that they expect to buy 35 JSFs per year, versus 50 in the current plan. Davis says the JSF office “is waiting for the POM (program objective memorandum) process to see those numbers get adjusted.”
