Defense Secretary Ash Carter on Monday urged Turkey and US-backed rebels in Syria to not engage each other and keep the focus on defeating ISIS, but Turkish forces continue to push beyond the recently claimed city of Jarablus. The Syrian Defense Forces (SDF) includes Kurdish YPG forces that Turkey has called terrorists and has repeatedly targeted. The SDF has promised to move to the eastern side of the Euphrates River and not try to claim any land. Turkish jets and forces have hit SDF positions, and a rocket attack killed a Turkish soldier, Al Jazeera reported. While Carter is calling on the two to stop the hostilities, Secretary of State John Kerry said last week the refusal of the SDF to move East of the Euphrates would mean an end of US support.
The Air Force is spending heavily on F-22 improvements through the end of the decade, suggesting it may not retire the jet in 2030 as it previously planned. New sensors, fuel tanks, communications, and electronic warfare systems are among the upgrades that comprise the package.
