The California Air National Guard participated in Clear Sky, a first-time exercise which began Oct. 8 and will conclude this week. U.S. aircraft involved include F-15C Eagles, KC-135 refueling planes, MQ-9 Reaper drones and a C-130J Super Hercules.
The effort is meant to “enhance regional capabilities to secure air sovereignty and promote peace and security through cooperation, collaboration and interoperability with NATO partners and other allies in the region.”
