I'm curious is it possible to see the RN doing shore bombardment like the German raid on Scarborough, Hartlepool and Whitby?
I mean they only have to contend with U boats and mines at this point. Too bad there's no rivers big enough to make a difference on land battles.
Sadly, there's so real way to do coastal bombardments against Germany, Kiwi. They are too well protected.
Helgoland Bight and its environs are arguably has some of the heaviest densities of naval mines on the planet either in this tl or the original one. There is the option of the Baltic, but even there, with lots of shallow waters, shifting bars and other hazards, it really wouldn't deliver up the kind of result that would even come close to making it worthwhile for the RN to attempt. This does not even bring in the high probability of U-boats or torpedo craft, and the negative effect they would achieve in such actions.
I've noted you mentioned rivers before, and while they can look like a good option, here again you are driving into easily mined shallow waters, while exposing yourself to high angle howitzer fire from either bank if it happens to be handy. the major concern beyond that is also things such as the ability to manoeuver, the most important one being the ability to turn around. Other matters to raise concerns are as simple as the silt present in a northern European river. the movement of ships, particularly large ones, would stir this up, which in turn would play merry hell with the ships condenser intake. It was an ongoing chronic problem for the High Seas Fleet at their main anchorage on the Jade, and there are apparently reported cases of ships being delayed or even forced to return from missions due to these issues.
All told, it was geographic position of Germany and her acsess to the sea that would have the biggest impact on both sides. For the Germans it meant their approaches were easily protected from the British, but at the same time, their tactical deployments would have far less options open to them.
For the British it was the exact opposite of course, in defending against the High Seas Fleet, they could better concentrate their forces against a German advance, but to attack the German coastal area would be prohibitive to the point of being nearly suicidal.
That is why the German position in WW2 was so much better for them, for by taking both Norway and the French Atlantic ports the had Great Britain out flanked, forcing them to spread their forces too thin.
Just imagine if you will, a ww2 German sailing without holding Norway or France. Even with just sticking to carrier based attack planes, the RN would have Hood, King George V, Prince of Wales, Rodney, possibly Nelson, one or two Revenge class, two or three aircraft carriers and a bunch of cruisers, destroyers and submarines. Even if the Germans threw in Tirpitz, Scharnhorst and Gneisenau, and what ever else they might have, they wouldn't be doing very well.
It really has very little to do with relative strength, rather it is more to do with Geographic limitations Mother nature had Germany penned in.
Hope that gives you a better idea. Any time you have a question, you're always welcome to ask!
