US deploying F-15C Eagle fighters to Turkey

Sources at the Pentagon said Tuesday that the US is sending 12 F-15C Eagle warplanes, armed exclusively with air-to-air missiles, to Turkey. The sources said the planes will protect US and Turkish warplanes carrying out airstrikes against ISIS targets in Syria, and be based at Incirlik airbase in southern Turkey.
DEBKAfile's military sources: Washington is sending the planes in response to Russia's deployment of Sukhoi Su-30s fighters to Syria.
None of the main combatants in the Syrian civil war, including the Syrian air force and ISIS, have such fighters, meaning that the F-15C Eagles will be used against the Russian fighters if they interfere with the US and Turkish bombing missions in Syria.
