DUBAI, United Arab Emirates » The U.S. Navy says a fighter jet has crashed into the Persian Gulf near the aircraft carrier USS Dwight D. Eisenhower, but both crew members were rescued safely by divers.

The Navy cited engine failure on the F/A-18F Super Hornet as the reason for today’s crash. An investigation is underway.

The Virginia-based Eisenhower is on a scheduled deployment in the Gulf region under the U.S. Navy’s 5th Fleet, which is based in Bahrain.

The U.S. has expanded naval maneuvers and drone surveillance in the region to counter growing Iranian military activity.
