The ships displaced 530- at deep load.
The destroyers were powered by two triple-expansion steam engines, each driving one propeller shaft using steam provided by four water-tube boilers of three different types. and used Normand boilers, and had du Temple boilers while the remaining three ships were fitted with Guyot boilers.

The ships carried of coal which gave them a range of 1000nmi1200nmi at a cruising speed of . Lansquenet had a capacity of which gave her a range of 2880nmi at the same cruising speed.[2]
