PREFACE This edition of Ordnance Pamphlet No. 755 includes descriptions and instructions for all ordnance assemblies installed in the main batteries of the six ships of the U.S.S. NORTH CAROLINA class. It is a revised text with addition of the chapters omitted in the issue dated February, 1941 but like that edition contains no illustrations other than diagrams and adjustment figures. The descriptions give reference to the general arrangement drawings; - those required for study of the text are listed in Appendix IV. The ordnance units of each turret have Lo-d.nch turret assembly designation and ship installation as tabulated below.
