I have some questions about amphibious operations (just the landing, not assault, which is even more complicated).
I assume that not all beaches are suited for a landing. What is the minimum size and maximum slope for the beaching of a small craft (LCVP, LCM, LCT) ? Same question for a LST.
I expect amphibious operations to be difficult in rough weather, despite historical counter exemples (Normandy). In which sea state it becomes dangerous or even impossible to sail in a small craft ? Same question for the deployment of small craft from a LSD / from a davies or deck of a ship. Same question for the beaching of a LST.
Since sea state may be a problem for amphibious operations, it may be better to land in a sheltered area. Not being a sailor, I don't realize how a bay or a creek can protect from heavy sea. Assuming a sea state of, let's say, 5 in open sea, what would it be in the sheltered area ?
I would like to estimate the time taken by a small craft to make a rotation. Transit time is easy to guess, but how long does it take to load and unload a LCVP / LCM / LCT ? How long does it take to unload a LST once beached ?
I assume that an unit that have been landed need space for defensive positions and stores. How much space does a batallon-sized unit need ?
Thanks for any help,
