Bismarck Sea was a Casablanca-class escort carrier, the most numerous type of aircraft carriers ever built, and designed specifically to be mass-produced using prefabricated sections, in order to replace heavy early war losses.
Standardized with her sister ships, she was 512 ft 3 in (156.13 m) long overall, had a beam of 65 ft 2 in (19.86 m), and a draft of 20 ft 9 in (6.32 m).
She displaced 8,188 long tons (8,319 t) standard, 10,902 long tons (11,077 t) with a full load.
She had a 257 ft (78 m) long hangar deck, a 477 ft (145 m) long flight deck.
She was powered with two Uniflow reciprocating steam engines, which provided a force of 9,000 horsepower (6,700 kW), driving two shafts, enabling her to make 19 knots (35 km/h; 22 mph).
The ship had a cruising range of 10,240 nautical miles (18,960 km; 11,780 mi), assuming that she traveled at a constant speed of 15 knots (28 km/h; 17 mph).
Her compact size necessitated the installment of an aircraft catapult at her bow end, and there were two aircraft elevators to facilitate movement of aircraft between the flight and hangar deck: one on the fore, another on the aft.

One 5 in (127 mm) /38 caliber dual purpose gun was mounted on the stern, and she was equipped with 16 Bofors 40 mm anti-aircraft guns in twin mounts, as well as 12 Oerlikon 20 mm cannons, which were used in an anti-aircraft capability.
By the end of the war, Casablanca-class carriers had been modified to carry 30 20 mm cannons, as a response to increasing casualties due to kamikaze attacks.
Anti-aircraft guns were mounted around the perimeter of the deck.
Casablanca-class escort carriers were designed to carry 27 aircraft, but she sometimes went over or under this number.
For example, during the Philippines campaign, she carried 16 Wildcat FM-2 fighters and 12 Avenger TBM-3 torpedo bombers, for a total of 28 aircraft.
During the Iwo Jima campaign, she carried 19 FM-2 fighters, and 12 TBM-3 torpedo bombers, for a total of 31 aircraft.
She was designed to accommodate 764 crew, but in wartime, her complement inevitably crept over that number.
A reasonable estimate puts the number of crew typically onboard a Casablanca-class escort carrier at around 910 to 916 men.
