Two U.S. Navy SEALs, Chief Special Warfare Operator Christopher J. Chambers and Navy Special Warfare Operator 1st Class Nathan Gage Ingram, drowned in January 2024 during a mission to intercept a ship carrying Iranian-made weapons to Yemen. A military investigation determined that their deaths could have been prevented, citing gaps in SEAL training and improper use of flotation devices as contributing factors.
The SEALs were part of a U.S. Navy operation in the Arabian Sea targeting the illicit transport of advanced missile components destined for Houthi rebel forces in Yemen.
While attempting to board the unflagged vessel in rough seas, Chambers slipped into the water, and Ingram followed in an effort to save him. Both were overwhelmed by their heavy equipment and the turbulent conditions. They allegedly died within seconds. Despite rescue efforts, neither SEAL survived.
The investigation identified “deficiencies, gaps, and inconsistencies” in training and preparedness, including improper functioning of emergency flotation devices. These devices, meant to keep the SEALs afloat, could not compensate for the additional weight of their gear.
After the tragedy, U.S. forces continued the mission, boarding the vessel and seizing Iranian-made missile components, including medium-range ballistic missiles and anti-ship cruise missiles.
Federal prosecutors have since charged four foreign nationals aboard the ship with attempting to smuggle the missile components. Despite initially claiming to have departed from Pakistan, the crew later admitted they had sailed from Iran. Ten additional crew members are being held as material witnesses.
Under international law, U.S. forces had the authority to board the vessel, which was classified as “without nationality” due to its lack of flag documentation. The vessel, deemed unseaworthy, was later sunk, and all 14 crew members were taken into custody and transported to Virginia for prosecution.
The investigation prompted changes in SEAL training and safety protocols within Naval Special Warfare Command to prevent future incidents. Both Chambers and Ingram were posthumously promoted. Ingram is also being considered for a commendation for his rescue attempt.
