The Maya class (摩耶型砲艦 Maya-gata hōkan?) was a four-ship class of gunboats of the early Imperial Japanese Navy.
The Maya vessels were Japan’s first iron-hulled gunboats, although only Maya and Chōkai had true iron hulls. Atago had a composite hull construction, whereas Akagi had a steel hull. All four vessels had auxiliary schooner-rigged sails. The Maya-class ships had an overall length of 47.0 metres (154.2 ft), a beam of 8.2 metres (26.9 ft), and a normal draught of 2.95 metres (9.7 ft). They displaced 614 long tons (624 t) at normal load. The crew numbered about 104 officers and enlisted men.
Propulsion was by a coal-fired horizontal double-expansion reciprocating steam engine with two cylindrical boilers driving a double screw. The engines were rated at 614 indicated horsepower (458 kW), and designed to reach a top speed of 10.25 knots (18.98 km/h; 11.80 mph).
The Maya-class ships were initially intended to be armed with one Krupp 210 mm (8 in) Krupp L/22 breech-loading gun, and one Krupp 120 mm (4.7 in) L/22 breech-loading gun, with two quadruple 1-inch Nordenfelt guns as secondary armament. However, each ship later modified to carry different armament in 1906.
