Project history: All boats had aircraft motors. Unlike British boats the German have been armed by one fixed bow TT instead of stern cradles. LM-type boats were used for coast defence, 14 were based on Belgium coast and 7 on Baltic.
Modernizations: 1918, LM21: + 1 - 450 TT
1926, UZ(S)14, 15: engines were replaced by 3 Mercedes-Benz (780hp)
Naval service: LM21 was converted to dispatch boat Siegfried in 1921 and latter two boats were sold (they were never commissioned) but all three were reverted to the navy in 1926 as ASW boats.
