In a concerning sequence of events, two U.S. Navy aircraft operating from the USS Nimitz crashed into the South China Sea within a half-hour span on Sunday afternoon, according to the Navy’s Pacific Fleet. The incidents involved an MH-60R Sea Hawk helicopter and an F/A-18F Super Hornet fighter jet. Fortunately, all five crew members—three from the helicopter and two from the jet—were rescued and reported to be in stable condition. The causes of the crashes remain under investigation. The USS Nimitz, which had been deployed to the Middle East for much of the summer as part of U.S. efforts to counter Houthi rebel attacks on commercial shipping, is now en route to its home port at Naval Base Kitsap in Washington state. This marks the carrier’s final deployment before its scheduled decommissioning. The crashes add to a series of recent mishaps involving U.S. Navy aircraft in the region. In December, an F/A-18 jet from the USS Harry S. Truman was mistakenly shot down by the guided-missile cruiser USS Gettysburg. In April, another F/A-18 slipped off the Truman’s hangar deck and fell into the Red Sea. In May, an F/A-18 attempting to land on the Truman went overboard after failing to catch the arresting cables, forcing its pilots to eject. While no fatalities occurred in these incidents, investigations into their causes are still pending.
