Plans for landing bridges and jetties offered possible answers to the problem of unloading an invasion force. The equipment discussed was unavailable until late 1941. One design successfully survived a North Sea winter test in 1941-42, demonstrating its ability to endure those conditions. Using such developments for an invasion of Britain would have required Germany to postpone its invasion of the Soviet Union for a long time. That choice is considered unlikely, especially while Germany still lacked the naval strength the operation required.

Landing jetties that arrived too late for Sea Lion
Later landing bridges and jetties offered useful technology but pushed a renewed invasion into conflict with Germany's Soviet campaign.
