So I was wondering, can't seem to find anything on the differences between the Higgins boat and the Landing Craft Assault. I don't know much about machines and so on, so reading their specs I can't tell. Do you think we would have then tried to use these british ships and all lost? or realized they were not good enough before hand and try another tactic, if so what tactic would they be? and lets pretend for a moment no other ship builders would have built a ship. Unless of course you know of ship builders of that time and what they might have made.
What do you mean not good enough? It was an extensively used and well liked craft used in almost every assault in the war by commonwealth forces.
It was even adopted by US Rangers (and other commando forces) for its quiet operation for raids.
It had limited capacity compared to the higgens boat, but that's why the commonwealth used LCM designs for larger loads.
The main differences between the LCA and the Higgins boat (LCVP) were in their design and role. The LCA was more heavily armoured, with bulletproof sides and bow ramp, and an armoured steering position. However, it was slow, capable of only 6-7 knots when loaded. In comparison, the Higgins boat was poorly armoured but fast, making 12 knots when fully loaded. Both were constructed mainly of wood, but the need to armour the LCA was a problem. This made it both a greater consumer of materials that could be useful elsewhere, and made it more difficult to mass produce. Peak monthly production of the LCA was 60 boats/month, while for the LCVP it was over 1000 per month. While LCA production could have been increased, it would have been unlikely to meet the heights of LCVP production. The LCVP could carry light vehicles, such as trucks or jeeps, while the LCA was limited to carrying infantry. While the British compensated for this by producing larger landing craft for landing light vehicles, this was inefficient compared to the single American design. The quieter, lower profile LCA was more suitable for raiding operations, while the LCVP was more useful for general operations.
