深く静かに潜航せよ (柏艪舎文芸シリーズ)

The tension on the submarine felt so real, especially the moments of silence and paranoia. I wonder what inspired the author to focus on this aspect of crew life?

The camaraderie and tensions seemed so genuine, but I’m curious whether that was based on real accounts or pure fiction.

The setting adds such a layer of suspense and history, but I wonder if there was a specific event or story that motivated this choice.
