Library Limbo, solved.

Found a book (borrowed it from my son really)…

Castles of Steel.

Logical extension of the last one Lusitania as many of the characters are the same, along with the time-frame and issues. Should be a good read. BTW: My paternal grandfather served in the US Navy during WWI, on one of these Dreadnoughts. In a classic variation on the oxymoron of Military Intelligence, his task was that of a lookout. He stared at the horizon for 8 hours a day.

The ironic part was that he was literally half-blind. Go figure.
