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.
Makes sense. The Navy really freaks out over any fire.
