    De Kalb County 188k Bow view of USS LST-715 at Mare Island Naval Shipyard, circa August 8, 1951, alongside of USS Askari (ARL-30). LST-715 was under repairs at Mare Island from 5 May to 9 August 1951. Visible just abaft the forward gun tubs is the elevator that transported vehicles carried externally, on the upper deck, to the tank deck so that they could be off loaded over the bow ramp. The structure abaft it is a short ramp leading to the elevator, opened up to reveal stowage between deck and ramp. Landing craft in the davits are LCVPs.
