    Warship Classification/Designation Discussion

    My working hypothesis is that the first two letters define the numbering series, and subsequent ones modify the first two. This is broken by DDGs and FFGs not falling into the DD and FF sequences, but otherwise it holds up reasonably well. Within submarines, there were the short-lived SC, SF...

Reading Norman Friedman's 'British Carrier Aviation' he mentions the American Patrol Escort (PE) idea of the 1950s. Basically...
