On the morning of Sunday, July 12, 2020, at 8:50 AM PDT, USS Bonhomme Richard (LHD-6) moored at Naval Base San Diego, Pier 2 reported a fire in the lower (Deep V) vehicle deck. The ship activated the emergency response system and a 3-alarm fire was triggered resulting in the dispatch of fire units from Federal, National City, and San Diego Fire Departments, along with crews from neighboring ships.

Over the course of the day, the fire grew in intensity, the crews were forced to withdraw due to explosions, and the conflagration spread the length of the entire deck.

In the video below, Dr. Salvatore Mercogliano examines the visual evidence of the first day and discusses his assessment of the fire, how it spread throughout the ship, and response by the ship’s crew, shore and afloat fire apparatuses.

There has been much reporting coming from the fire on board #BonhommeRichard. As a former mariner, now historian & firefighter, I examined the first day response to provide an early assessment of the largest Navy ship fire since Normandie in Feb. 1942. https://t.co/TchGXynyU9
