Query: Match bearings and fire, an excellent technical winner

I've had many novels about subsurface combat and undersea naval warfare pass through my hands. Few have been as technically accurate and as true to the logic of naval strategy as this one. While some of the weapon systems are beyond modern technology, the fundamental thrust and parries of undersea warfare were a joy to behold. I especially enjoyed seeing the humour that abounds within the submarine community, but is often omitted in other novels, being represented. I will certainly seek out his other works to see if they hold true to the same rich characters and high technical content.
