The Navy's new refueling drone completed its first test flight over the weekend. The MQ-25A Stingray is the Navy's first carrier-based unmanned aircraft. Right now, there are no unmanned refueling aircraft in service, but the Navy said the Stingray is expected to enter service in 2027.

Built by Boeing, the Stingray costs about $209 million per unit. The Navy invested about $16 billion in the system. After years of delays in the Stingray's development, this test flight gets the Navy closer to using it in military operations.

The Navy says the drone will be a valuable tool to extend the reach of crewed fighters and aircraft.

A US Air Force A-10 Thunderbolt II was shot down in Iran while attempting to rescue crew members from the downed F-15 Strike Eagle fighter jet. According to US officials, the pilot safely ejected over friendly territory and was unharmed.

Known as the Warthog, the A-10 has been in service since 1977… but the Air Force has been pushing to retire it from service, deeming the aircraft obsolete.
