Ship project history:
Cutters intended for service in Northern
Atlantic (ice circumstances observation, for what their hulls were strengthened).
Machinery of the ships included spread enough
in the USA turbo-electric gear. They were differed good habitability for their
dimensions, however a number of the lacks was generic in them, not allowing to
consider them as rigorous combat ships: the hull had insufficient subdivision on
watertight compartments, bulkheads did not reach an upper deck which besides on
the big extent was wood (not steel, sheathed by a wood, and continuous wood as
by sailing frigates).
