In this last week of A&D for 2022, we are pleased to publish an index, with links, to all those articles as encouragement for some provocative reading over the coming holidays.

Nuclear subs are a poor design. Conventional and nuclear submarines use hybrid technology: diesel or nuclear reactor power an electric motor. You can turn a diesel engine off for ‘silent running’, but a nuclear reactor must run continuously, or it melts down: it needs to pump cooling water and dump heat back into the ocean. The enemy can hear those pumps on their sonar; and the hot water leaves a thermal plume that can spotted with thermal imaging. China already has 60 submarines - you’re not getting anywhere near the South China Sea before being spotted.
