Haida (WPG-45), Modoc (WPG-46), Mojave (WPG-47),
and Tampa (WPG-48)
These cutters, launched in 1921, were assigned to the Greenland patrol.
165 foot patrol boats: 337 tons, 16 knots, 2x3" & 2x20mm guns.

Thetis (WPC-115) and Triton (WPC-116)
These low endurance cutters were built in the early 1930's. Cutters of this class are credited with sinking U-157 and U-352 off the southeastern United States.
165 foot gunboats: 1005 tons, 13 knots, 2x3" & 3x20mm guns.
Algonquin (WPG-75), Comanche (WPG-76), Escanaba (WPG-77)
Mohawk (WPG-78), Onondaga (WPG-79), and Tahoma (WPG-80)
These high endurance cutters, launched in 1934, were too slow for effective convoy escort. Tampa, Comanche, and Escanaba were escorting small convoy SG-19 when 5252 ton United States Army transport Dorcester was torpedoed by U-456. 677 men died in what is remembered as one of the United States worst troopship losses of the war. Escanaba was destroyed off Ivigtut, Greenland, 13 June 1943 by an explosion of undetermined cause. There were only 2 survivors from her crew of 105.
327 foot gunboats: 2216 tons, 20 knots, 125 men.
Bibb (WPG-31), Campbell (WPG-32), Duane (WPG-33),
Alexander Hamilton (WPG-34), Ingham (WPG-35),
Spencer (WPG-35) and Taney (WPG-37)
These cutters were built at the Philadelphia, New York, and Charleston navy yards in 1936 using the Washington naval treaty gunboat pattern of USS Erie (PG-50). (Erie was torpedoed by U-163 off Curacao on 12 November 1942.) The cutters rejected treaty armament of four 6"/47 guns in favor of lighter weapons. Taney mounted 4 single 5"/38 guns in enclosed mounts; but was considered less satisfactory than the remaining cutters which carried 3 single 5"/38 and 3 single 3"/50 guns in open mounts. Two cutters were assigned to each of the American transatlantic convoy groups. Those escort groups were filled out with Canadian corvettes and a few American flush deck destroyers. Hamilton was torpedoed by U-132 off Iceland and capsized in tow on 29 January 1942. Cutters of this class are credited with sinking U-175, U-606, and U-626 on the North Atlantic convoy routes.
304 foot frigates: 1430 tons, 18 kts, 180 men, 3x3" and 10x20mm guns.

American shipyards built a modified version of the Royal Navy's RIVER class frigate. The United States Navy preferred American designed destroyer escorts being produced at the same time. The frigates (except for 21 delivered to the Royal Navy as their COLONY class) were assigned to Coast Guard personnel experienced with reciprocating machinery. Like the Coast Guard manned destroyer escorts, however, these ships were not officially transferred from the Navy to the Coast Guard. Moberly shares credit for sinking U-853 off New York.
255 foot gunboats: 1563 tons, 18 knots, 150 men, 2 twin 5"/38 guns.

Minnetonka (WPG-67), Androscoggin (WPG-68)
Mendota (WPG-69) and Ponchartrain (WPG-70)
These were the first wartime constructed gunboats actually transferred to the Coast Guard. They were intended to replace the cutters loaned to the Royal Navy, and some repeated the names of earlier wartime losses. Delivery began in mid-1944, and some were not completed until after cessation of hostilities.
