The Kawasaki Ki-48 , 九九式雙發輕爆擊機 ( shiki-souhatu-keibaku , ) shortened to 'Sokei ' , Army Type 99 Twin-engined Light Bomber , was a Japanese twin-engine light bomber that was used during World War II . Its Allied reporting name was Lily .
The Imperial Japanese Army ( Japanese : 大日本帝国陸軍 , Hepburn : Dai-Nippon Teikoku Rikugun , Army of the Greater Japanese Empire ) was the official ground-based armed force of the Empire of Japan from 1868 to 1945 . It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army , both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the navy . Later an Inspectorate General of Aviation became the third agency with oversight of the army . During wartime or national emergencies , the nominal command functions of the emperor would be centralized in an Imperial General Headquarters ( IGHQ ) , an ad-hoc body consisting of the chief and vice chief of the Army General Staff , the Minister of the Army , the chief and vice chief of the Naval General Staff , the Inspector General of Aviation , and the Inspector General of Military Training .
The Mitsubishi G3M ( Kyūroku-shiki rikujō kōgeki-ki ( 九六式陸上攻撃機 ) : Type 96 land-based attack aircraft Rikko ; Allied reporting name Nell ) was a Japanese bomber and transport aircraft used by the Imperial Japanese Navy Air Service ( IJNAS ) during World War II .
The Imperial Japanese Navy ( IJN ; Kyūjitai : 大日本帝國海軍 Shinjitai : 大日本帝国海軍 Dai-Nippon Teikoku Kaigun ( help·info ) Navy of the Greater Japanese Empire , or 日本海軍 Nippon Kaigun , Japanese Navy ) was the navy of the Empire of Japan from 1868 until 1945 , when it was dissolved following Japan 's surrender in World War II . The Japan Maritime Self-Defense Force ( JMSDF ) was formed circa 1952-1954 after the dissolution of the IJN . The Imperial Japanese Navy was the third largest navy in the world by 1920 , behind the Royal Navy and the United States Navy ( USN ) . It was supported by the Imperial Japanese Navy Air Service for aircraft and airstrike operation from the fleet . It was the primary opponent of the Western Allies in the Pacific War . The origins of the Imperial Japanese Navy go back to early interactions with nations on the Asian continent , beginning in the early medieval period and reaching a peak of activity during the 16th and 17th centuries at a time of cultural exchange with European powers during the Age of Discovery . After two centuries of stagnation during the country 's ensuing seclusion policy under the shōgun of the Edo period , Japan 's navy was comparatively backward when the country was forced open to trade by American intervention in 1854 . This eventually led to the Meiji Restoration . Accompanying the re-ascendance of the Emperor came a period of frantic modernization and industrialization . The navy had several successes , sometimes against much more powerful enemies such as in the Sino-Japanese War and the Russo-Japanese War , before being largely destroyed in World War II .
The Mitsubishi G4M ( long designation : Mitsubishi Navy Type 1 attack bomber : 一式陸上攻撃機 , 一式陸攻 Ichishiki rikujō kōgeki ki , Ichishikirikkō ) was the main twin-engine , land-based bomber used by the Imperial Japanese Navy Air Service in World War II . The Allies gave the G4M the reporting name Betty . Japanese Navy pilots called it Hamaki ( 葉巻 , cigar , lit . leaf roll ) due to its cylindrical shape . The G4M had very good performance , especially in operational range ; this was achieved by its structural lightness and an almost total lack of protection for the crew , with no armor plating or self-sealing fuel tanks . These omissions proved to be the aircraft 's weakness when confronted with American fighter aircraft during the Pacific War .
The Mitsubishi Ki-21 ( or Type 97 Heavy Bomber ) ( 九七式重爆撃機 Kyūnana-shiki jūbakugekiki ) ( Allied reporting name : Sally /Gwen ) was a Japanese heavy bomber during World War II . It began operations during the Second Sino-Japanese War participating in the Nomonhan Incident , and in the first stages of the Pacific War , including the Malayan , Burmese , Dutch East Indies and New Guinea Campaigns . It was also used to attack targets as far-flung as western China , India and northern Australia .
The Mitsubishi Ki-30 ( 九七式軽爆撃機 , Kyunana-shiki keibakugekiki ) was a Japanese light bomber of World War II . It was a single-engine , mid-wing , cantilever monoplane of stressed-skin construction with a fixed tailwheel undercarriage and a long transparent cockpit canopy . The type had significance in being the first Japanese aircraft to be powered by a modern two-row radial engine . During the war , it was known by the Allies by the name Ann .
The Imperial Japanese Army ( Japanese : 大日本帝国陸軍 , Hepburn : Dai-Nippon Teikoku Rikugun , Army of the Greater Japanese Empire ) was the official ground-based armed force of the Empire of Japan from 1868 to 1945 . It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army , both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the navy . Later an Inspectorate General of Aviation became the third agency with oversight of the army . During wartime or national emergencies , the nominal command functions of the emperor would be centralized in an Imperial General Headquarters ( IGHQ ) , an ad-hoc body consisting of the chief and vice chief of the Army General Staff , the Minister of the Army , the chief and vice chief of the Naval General Staff , the Inspector General of Aviation , and the Inspector General of Military Training .
The Mitsubishi Ki-67 Hiryū ( 飛龍 , Flying Dragon ; Allied reporting name Peggy ) was a twin-engine medium bomber produced by Mitsubishi and used by the Imperial Japanese Army Air Force and Imperial Japanese Navy Air Service in World War II . Its Army long designation was Army Type 4 Heavy Bomber ( 四式重爆撃機 ) . Its Navy designations were P2M and Q2M . [ citation needed ]
The Nakajima Ki-49 Donryu ( 中島 キ-49 呑龍 ) Storm Dragon was a twin-engine Japanese bomber aircraft of World War II . Despite its official name as Army Type 100 Heavy Bomber , the requirements of the Ki-49 - to operate unescorted , with heavy defensive armament and armor - restricted it to a small bomb load , initially 1,000 kg ( 2,200 lb ) . A mid-wing , cantilever monoplane of all-metal construction , the Ki-49 was one of the first Japanese aircraft fitted with a retractable tailwheel . During World War II , it was known to the Allies by the reporting name Helen .
The Yokosuka P1Y Ginga ( 銀河 , Galaxy ) was a twin-engine , land-based bomber developed for the Japanese Imperial Navy in World War II . It was the successor to the Mitsubishi G4M and given the Allied reporting name Frances .
