Kawasaki 98

Flown by Japanese army and navy pilots, this is an excellent development of the Seversky P-35 licensed for Jap manufacture after abandonment by US Army. Powered by twin-row Kinsei radial engine, it has maximum speed of 280 mph at 10,000 feet. Cruising speed is estimated at 240 mph, service ceiling is 32,000 feet, weighs only 5,000 pounds with a bomb load of 500 pounds. The 98 has span of 29', is 23' long.

Wing is low cantilever type, elliptical contour, slight outboard dihedral, pronounced fillets.

Engine has radial cowling, straight top line, extends only slightly forward from wing.

Fuselage is short, thick in profile, with long greenhouse tapering almost to vertical fin.

Tail is extremely large, tapered fin, elliptical rudder, tapered stabilizers, elliptical elevators.

Powered by one 900-hp Kawasaki liquid-cooled engine, it has top speed of 236 mph, cruising speed of 206 mph at 13,120 feet. Service ceiling is 25,000 feet, cruising range is about 500 miles. It carries a bomb load of 800 pounds. The 97 has wing span of 47' 9", weighs 7,000 pounds fully loaded.

Wing is low cantilever type, slight taper on leading edge, marked taper trailing edge, dihedral.

Engine is in line type with long nose, squarish BMW type radiator, prop below top line.

Fuselage is long, tapers aft of wing to tail cone, greenhouse over wing tapers sharply to tail.

Tail is extremely high, triangular fin and rudder set forward from tail cone, elliptical tailplane.

Inline Engine, Tall Tail

Mitsubishi 98

With greater armament, heavier bomb load than its 1937 progenitor, the Mitsubishi 98 ranks as an important Jap light bomber, reconnaissance aircraft. Powered by Mitsubishi Kinsei IV radial engine, developing 900 hp at 9,000 feet, it has top speed of 250 mph at 11,000 feet, cruising speed of 208 mph. Range is 280 miles with 1,240 pound bomb load. The 98 has wing span of 46', is 26' 2" long.

Wing is low cantilever type, straight center section, almost straight trailing edge.

Engine has radial cowling, long nose, large prop spinner, prominent intake on top of cowl.

Fuselage bears close resemblance to BT-9 airframe, long greenhouse extending fore and aft of wing.

Tail is very high, sharp taper on fin, and stabilizers slight taper rudder and elevator.

High Tail Far Back

133
Mitsubishi Karigane

Developed from the Kamikaze, which means Divine Wind, this Wild Goose serves the Jap army as a light bomber. Powered by one 800-hp Mitsubishi 14-cylinder radial engine, it has top speed of 310 mph, cruising speed of 200 mph with bomber loading, range of 1,490 miles. Like other Jap monoplanes, it is very light, weighing only 5,060 pounds fully loaded. The Karigane has wing span of 39½', measures 28' in length.

Wing is low cantilever type, dihedral outboard, gull-shape trailing edge, straight leading edge.

Engine has radial cowling, long nose, straight top and bottom lines, large prop spinner.

Fuselage is long, cleanly-tapered, with greenhouse set far back, tapering slightly to tail.

Tail is low and very broad, equi-taper rudder and fin, equi-taper stabilizer and elevators.

Low Tail, Long Canopy

134
Mitsubishi Kamikaze

Sometimes confused with its successor, the Karigane, this plane can be easily distinguished from the latter by bulbous cowl. Powered by 800-hp Kotobuki radial engine, it has top speed of 260 mph at 15,000 feet, cruising speed of 220 mph. Range is 960 miles on reconnaissance duties, 450 miles with 660 pound bomb load. It has two 7.7 guns firing through prop. The Kamikaze has span of 40', is 27' long.

Wing is low cantilever type, tapered leading edge, semi-gull trailing edge, square tips.

Engine has radial cowl larger than fuselage front section, curved top and bottom lines.

Fuselage is long, thick in profile, greenhouse extends well aft of wing, tapers into tail.

Tail is low, very broad, equi-taper rudder and fin, narrow triangular tailplane.

Big Cowl, Narrow Tailplane

135
Nakajima 97

Developed from the Nakajima 96, this Jap army fighter has slightly better performance than its progenitor despite larger size, greater weight. Powered by 750-hp Nakajima Hikari radial engine, it has maximum speed of 280 mph at critical altitude, 240 mph at sea level. Cruising speed is estimated at 200 mph, maximum range is 389 miles. Two guns in wings, one in cowl, fire 500 rounds each. The 97 has span of 38', is 27' long.

Wing is low cantilever type, slight sweep-back, slight tip dihedral, elliptical contour.

Engine has radial cowling larger than fuselage forward section, very short nose, big spinner.

Fuselage resembles that of Boeing P-26A with a thick forward section, sharp taper to tail.

Tail is very low and small, triangular fin and elliptical rudder, elliptical tailplane.

Small Tail, Big Nose
136
Mitsubishi 104

Except for change in tail structure, this development of the Type 98 is closely akin to BT-9 in structure and appearance. Powered by 900-hp Mitsubishi Kinsei radial, is has maximum speed of 250 mph, cruising speed of 210 mph, range of about 260 miles, service ceiling of 25,000 feet. It carries crew of two or three, bomb load of 3,300 pounds, has three machine guns. It has wing span of 46', is more than 35' long.

Wing is low cantilever type, straight center section, leading edge taper, straight trailing edge.

Engine has radial cowling with short nose, straight top and bottom lines, no prop spinner.
