practically every type except LCI(L)'s are retained for purely
 
logistical support depends upon:
 
(1) Availability of a port and port facilities.
 
(2) The possibility from an equipment and hydrographical
 
viewpoint of constructing a pier.
 
(3) The feasibility and desirability of using  seagoing
 
types of landing craft to transport supplies from the base
 
to the operating area.
 
c. Availability of salvage and repair facilities. A good
 
percentage of the landing craft will probably require salvage
 
and a large percentage overhaul after an operation. The
 
availability of spare parts and assistance by shore estab-
 
lishments or tenders in providing mechanics and machinery
 
 will determine the time interval for overhaul.  It takes more
 
time to repair many landing craft than it does to repair a
 
few. This is because of docking facilities, repair crews,
 
time for shifting berth under own power or by towing, etc. 
 
All of these factors must be considered in determing time
 
required for salvage and repairs.                                                
 
     5. Examination of capabilities of moving landing craft from one theater to another.
 
Bearing in mind the varying types required and the governing 
 
factors discussed in the preceding paragraph, an examination
 
will be made of the possibility of moving landing craft from one
 
theater to another (or from one capaign to another) for the
 
purpose of determining availability at a certain time and place.
 
6. There are three main sources from which landing craft
 
may be obtained, namely the ATLANTIC, the PACIFIC,
 
 and new production in the UNITED STATES.  For convenience,
 
 these have been designated  "Alantic Pool",  "Pacific Pool" and "Production
 
Pool" and are discussed in Appendices "A", "B", and "C."
 
Pertinent factors from these studies are set forth below.
