Development and design

The three Atsumi-class tank landing ships (LSTs) had a standard displacement of 1,500 tonnes (1,500 long tons) and 2,400 t (2,400 long tons) at full load. They were 89 m (292 ft 0 in) overall with a beam of 13 m (42 ft 8 in) and a draft of 2.7 m (8 ft 10 in). Ships in the class were powered by two Kawasaki-MAN V8V 22/30 AMTL diesel engines turning two shafts rated at 3,300 kilowatts (4,400 bhp). This gave them a maximum speed of 14 knots (26 km/h; 16 mph).[1]

Vessels of the class carried two Landing Craft Vehicle Personnel (LCVPs). The LCVPs were slung under davits and a traveling gantry crane with folding rails that could be extended over the side handled the two LCMs positioned on the foredeck. The LSTs could carry up 130 troops. The Atsumi class were armed with twin-mounted 40 mm (1.6 in) guns in a single turret placed each at the bow and aft. The LSTs were equipped with OPS-9 air search. They had a complement of 100 officers and crew.
