An F/A-18 Super Hornet assigned to the Nimitz-class aircraft carrier USS Ronald Reagan went down on Monday morning while conducting routine operations over the Philippine Sea. Both pilots were successfully rescued and suffered only minor injuries.

According to a U.S. Navy statement, the Super Hornet was conducting routine operations when it suffered a serious mechanical failure. When it became apparent that the pilot could not regain control of the fighter, the decision was made to eject.

“The crew was immediately and safely recovered by USS Ronald Reagan (CVN-76) search and rescue aircraft and brought back to the ship for evaluation by medical personnel. Both aviators are in good condition. Ronald Reagan has resumed normal operations,” the press release reads. It goes on to say that an investigation into the exact cause of the incident is already underway. Thus far, Navy officials have opted not to comment on what may have caused the Super Hornet to fail.

Monday’s incident marks the second aviation mishap for the Ronald Reagan in just the past month. On October 19th, an MH-60R Seahawk crashed into the carrier’s flight deck, injuring a dozen sailors in the process. The U.S. Navy has seen a number of tragic and high-profile incidents in recent years, including a rash of aircraft crashes and even collisions between American warships and commercial vessels.
