Propulsion was by a coal-fired double-expansion reciprocating steam engine with six cylindrical boilers driving a double screw.
13.
There were initially two generators driven by reciprocating steam engines, supplied by 24 boilers burning coal brought by collier from Newcastle.
14.
Propulsion was by a coal-fired horizontal double-expansion reciprocating steam engine with two cylindrical boilers driving a double screw.

However, in actual testing the Tesla Turbine had expansion efficiencies far below contemporary steam turbines and far below contemporary reciprocating steam engines.
16.
The power plant and propulsion system represented unfamiliar technology at the time when all Soviet icebreakers were still powered by reciprocating steam engines.
17.
At the outset, the available generating sources were hydroturbines where falling water was available, and reciprocating steam engines where it was not.
