Ship project history: USN Coast guard cutters, transferred to RN by lend-lease in April-June, 1941.
They concerned to two very close Tahoe and Saranac classes, differing only in
details.
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, but rare in UK, 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). Insufficient,
to RN measures, there was also stability.
After transfer to UK cutters, reclassified to sloops, have passed the update
directed on correction of the majority of these lacks. In particular, 30ts of a
ballast were laid, some re-planning of internal premises had conducted and
absolutely improper armament was modernized for ASW operations.They received
sonar, 2 DCT and DCR.
