The Glatton inquiry drove a full insulation safety refit

The Royal Navy used Gorgon to investigate why her sister had exploded, checking the same magazine and machinery boundaries in a nearly identical metal hull. Initial signs of heating did not by themselves explain the disaster, so the inspection widened when the navy decided to replace the cork insulation. Workers then found missing cork, newspaper filling some gaps, and absent rivets that created paths for air and embers. Silicate wool offered better insulation and was fitted in the affected spaces during 1919. The work continued even though Gorgon's long-term future was uncertain, indicating that the navy still regarded her as potentially useful. Possible Yangtze flagship service and other options show that the ship was not discarded casually. The refit became an example of learning from a sister ship's loss through physical comparison and corrective engineering.
