The Navy is investigating the fuel supply of aircraft carrier USS Nimitz (CVN-68) as a possible cause for two U.S. aircraft crashes in the South China Sea, President Donald Trump told reporters during a press gaggle on Monday.

Two US Navy aircraft — a fighter jet and a helicopter — crashed into the South China Sea within just 30 minutes of each other during the USS Nimitz’s final deployment. Thankfully, all five crew members survived.

President Donald Trump on Monday suggested that the recent crashes of two U.S. Navy aircraft could be tied to “bad fuel.”

The Navy's Pacific Fleet says a fighter jet and a helicopter based off the aircraft carrier USS Nimitz crashed into the South China Sea within 30 minutes of each other.

The USS Nimitz aircraft carrier has made headlines for its planned retirement, but several other U.S. Navy ships are set to be decommissioned in 2026.
