Admiralty M-N Scheme - Wikipedia

en.wikipedia.org en.wikipedia.org

The Admiralty M-N Scheme' (sometimes given as "Project M-N") was a World War I British plan to close the Strait of Dover in the English Channel to German U-boats, by means of a chain of either eight or twelve massive towers linked by anti-submarine booms and nets. Only two towers had been constructed before the Armistice with Germany caused the cancellation of the project.


Does anyone have more information on this saying how long it was expected to take to complete?

Looking at the wiki page, it says Tower No 1 was almost complete in November 1918, having started in June 1918, so call it 6-8 months per tower, but with at least some parallel working on Tower No 2. Unless they planned on increasing the number of towers being worked on at once, or a substantial learning curve gain, it looks like a minimum of two years with full two at once construction for eight towers, or four plus if they just work on one at a time, and 50% more if they go for twelve.

Per this site, the second tower was 'not far behind' and preliminary work may have started on as many as twelve others, for a total of fourteen. The bases for a total of six are claimed to have been constructed at Shoreham.
 
Re the second tower, it would have been slightly amusing if there had been a need for two lighthouses at this time....
 
I think it was opportunistic to use the completed tower to replace the Nab lightship, it’s not as if it needed to be replaced.
