The ATR-1 tugs serviced World War II in both Asiatic-Pacific Theater and the European theatre of World War II. The 40 ATR-1-class vessels had a displacement of 852 tons light and 1,315 tons fully loaded. They had a length of 165 feet 6 inches (50.44 m), a beam of 33 feet 4 inches (10.16 m) and a draft of 15 feet 6 inches (4.72 m). The tugs had a top speed of 12.2 knots (22.6 km/h; 14.0 mph). The largest boom had a capacity of 4 tons. They were armed with one 3"/50 caliber gun and two single Oerlikon 20 mm cannon. The crew had five officers and 47 enlisted men. They had a fuel capacity of 1,620 barrels (68,000 US gal). The propulsion was one Fulton Iron Works vertical triple-expansion reciprocating steam engine with two Babcock & Wilcox "D"-type boilers with a single propeller creating 1,600 shaft horsepower (1,200 kW). They had two turbo drive Ships Service Generators, rated at 60 kW 120 V D.C. An example is USS ATR-31.^[4][5][6][7]

Fulton Shipyard built troopships of the APc-1-class small coastal transports design. The ship had a displacement of 100 tons light, 258 tons fully loaded with a length of 103 feet (31 m), a beam of 21 feet (6.4 m), a draft of 9 feet (2.7 m), and a top speed of 10 knots (19 km/h; 12 mph). The crew was composed of 3 officers and 22 enlisted men and could transport up to 66 troops. The vessels had a large boom with a capacity of 3 tons. They were armed with four single 20 mm AA guns. the APc-1 class had a fuel capacity of 145 barrels (6,100 US gal) of diesel fuel. They were powered by one Enterprise Engine DMG-6 diesel engine with a single propeller creating 400 shp (300 kW). For electrical they had two diesel 30 kW 120V D.C. service generators. The ship moved troops in the Pacific War. A notable ship was USS APc-25.^[8][9][10]

Fulton Shipyard built Accentor-class minesweepers, with a displacement of 185–205 long tons (188–208 t), a length of 97 ft 1 in (29.59 m)–98 ft 5 in (30.00 m), a beam of 21 ft (6.4 m)–23 ft 7 in (7.19 m), and a draft of 8 ft 11 in (2.72 m)–10 ft 8 in (3.25 m). The minesweepers were powered by a diesel engine with 400 hp (300 kW) and a top speed of 10 knots (19 km/h; 12 mph). A crew of 17 manned the ship and deck guns. Armament was a two .50 cal. M2 Browning machine guns. Accentor-class minesweepers were used to sweep naval mines in harbors, bays, and other littoral waters, due to their small size. Notable ships: USS Industry, USS Liberator, USS Loyalty, USS Memorable, USS Merit and USS Observer.^{[11][12][13][14]}

Fulton Shipyard built Agile-class minesweepers with a displacement of 853 tons full, a length of 172 ft (52 m), a beam of 35 ft (11 m), and a draft of 10 ft (3.0 m). The vessels were powered by four Packard ID1700 diesel engines, with 2,280 brake horsepower (1,700 kW) and two controllable pitch propellers. The ships had a top speed of 14 knots (26 km/h; 16 mph). The ship crew was 7 officers and 70 enlisted men. The minesweepers were armed with one Bofors 40 mm gun and two .50 cal (12.7 mm) twin machine gun. Notable ships: USS Conflict and USS Constant.^[15][16][17]
