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).
Modernizations: 1946,
1946, Chelan, Champlain, Mocoma were returned with armament: 1 x 1 - 102/45 CP Mk II, 1 x 1 - 76/45 Mk II, 2 x 1 - 40/39 Mk VIII, 4 x 1 - 20/70 Mk III, 1 x 24 - 178 Hedgehog Mk X ASWRL, 2 DCT, 2 DCR (100), presumably type 271 or type 277 radar
1946, Itasca was returned with armament: 1 x 1 - 102/45 CP Mk II, 1 x 1 - 40/60 Mk III, 4 x 1 - 40/39 Mk VIII, 4 x 1 - 20/70 Mk III, 1 x 24 - 178 Hedgehog Mk X ASWRL, 2 DCT, 2 DCR (100), presumably type 271 or type 277 radar
1946, Sebec was returned with armament: 1 x 1 - 102/45 CP Mk II, 3 x 1 - 76/45 Mk II, 7 x 1 - 20/70 Mk III, 1 x 24 - 178 Hedgehog Mk X ASWRL, 2 DCT, 2 DCR (100), presumably type 271 or type 277 radar
1947, Itasca, Tampa, Mocoma were presumably armed with 1 x 1 - 127/51 Mk 13, (2-3) x 1 - 76/50 Mk 21/22, (2-4) x 1 - 20/70 Mk 10, presumably type 271 or type 277 radar
Naval service: All ships of class were transferred to Royal Navy by lend-lease.
