Joey, the Navy dock at Algers is nearly a mile long. You can see it on the overhead images on which ever website you prefer, just look for "Naval Support Activity".
To see how an LCT was placed on a "T" checkout http://www.ww2lct.org
and there is a clip of an LCT being launched off a "T".
The Ammo Dump would have been more or less bunkers and revetments and the dock area isolated. The big dump at Port Chicago, Ca can still be made out from overhead photos, thats where 4000 tons on a Liberty Ship blew up in '44 while being loaded
Help here Seabat or anybody, which website has the inital provisioning list For one of the LST's?
