Ottoman Building Plan 1915-1916

[miketr]

The Ottomans will be receiving a 1908 FC control to equip the new ship with.  This is an improved Yavuz with a slight increase in size, a little faster and more range.

The Ottomans will build two more mine laying cruisers and ten of the new torpedo boats. in the same time period.
