According to USNI News, the Theodore Roosevelt Carrier Strike Group left U.S. 5th Fleet on Tuesday with no public timeline for when its replacement will reach the Middle East to continue U.S. air strikes against Islamic State in Iraq in Syria (ISIS) targets.(…)
While in 5th Fleet, the Roosevelt CSG was the largest symbol in the U.S.-led anti-ISIS collation responsible for „1,812 combat sorties totaling 10,618 combat flight hours, taking on 14.5 million gallons of jet fuel and expending 1,085 precision-guided munitions,“ as part of Operation Inherent Resolve, according to a Tuesday statement from the service.
Which probably does not explain why in over a year, the US did less damage to ISIS then the Russian airforce has achieved in less than a month.
