I think this discussion needs a smattering of fog of war and reality to enter the mix.
Technical discussions on paper soon enter the waste basket in war. We lost enough high tech naval assets to relatively low tech delivered munitions in the Falklands to remind us of that.
An interesting comment was that "If we had taken our stored WW2 Barrage Balloons with us we may not have lost so many ships" is interesting.
Rules of war.
The enemy will do something you have not anticipated.
Plans vary rarely go to plan.
If the enemy can get through (our defences) it will get through.
Most importantly, never underestimate the enemy.
