5" DP Mounts

As noted above, I believe that the data in this book for 5"/38 DP single pedestal and base ring gun mounts to be in error. For this reason, I have performed my own counts for the number of 5" mounts available on 1 July 1940. Only ships actually in commission on 1 July 1940 are included in this first table.

Additional information on 5" mountings may be found on the data page for 5"/38 Mark 12 guns.

Pedestal 5"/38 Mounts on 30 June 1945

In this second table, only pedestal mounts are counted and only those ships in commission on 30 June 1945 are included. The horrendous losses among the pre-war destroyers is amply indicated.

Notes

  • ^1.11.2The data in the book has erroneous data for the quantity of 5"/38 pedestal and base-ring single mounts. For that reason, I have substituted my own counts for these two items in the tables above in section 5" DP Mounts .
  • ^Percentages from book. However, the Mark 37 was a very simplified 5"/38 mounting used only on Merchant ships. 5"/38 guns used on Escort Carriers were actually Mark 30 Mods lacking shields, axial hoists and RPC, and were somewhat similar to the Mark 37 only in a general sense..
