Why wartime landing-craft lists are never exhaustive

Was the lecture's list exhaustive of wartime landing-craft types and variants?

No. It covered the principal designed types, while theatre commanders and crews produced many additional conversions and local variants.

The named craft in the lecture are the principal designed types rather than an exhaustive wartime inventory. As the war continued, hulls accumulated local variants and modifications for particular operations. Admiral Cunningham, for example, had latitude to alter available craft around Crete and other Mediterranean demands. The proliferation explains why using landing craft as a generic label can conceal important differences in role, weapons, and theatre adaptation.
