USS Kearsarge is a sister ship of the USS Bonhomme Richard, both ships are members of the Wasp-class.
The incident was relatively minor. A welding spark ignited a pile of material. Fortunately, a “fire watch” quickly extinguished the fire.
However, the Navy reacted decisively and completely shut down all work by General Dynamics on the USS Kearsarge pending a review of their safety protocols.
It is noteworthy that General Dynamics was in charge of the work on the USS Bonhomme Richard.
