The Mitsubishi G3M (九六式陸上攻撃機: Type 96 Land-based Attack Aircraft "Rikko"; Allied reporting name "Nell") was a Japanese bomber used during World War II.

Design and development

The G3M has its origins in a specification submitted to the Mitsubishi company from the Imperial Japanese Navy requesting a heavy bomber aircraft with a range figure unprecedented at the time. This principally stemmed from Admiral Isoroku Yamamoto's influence in the Naval High Commission on the necessity of a heavy bomber capable of encompassing the enormous ranges of the arenas where Imperial Japan sought to conquer in the years to come, including those outlined in the expansionist Tanaka Memorial - namely China, Southeast Asia, the Pacific Isles and the vast far east of the Soviet Union. The requirement for payload was also unprecedented in Japanese military aviation history, though necessary to accommodate the aerial torpedo envisaged to combat the armoured battleships of the Allies in the geographical broadness of the Pacific front. The speed requirement submitted by the Naval Department was again also unprecedented, not only in Japanese but also in international heavy bomber aviation, where in relation to the envisaged Japanese battlegrounds of China and the Pacific, the bomber would need to not only cover long distances, but necessarily have exceptional speed to strike distant targets with a minimum attack time. Thus the G3M was an embodiment of Japanese military aircraft design in the brief period leading to the Pacific War, with powerful offensive armament (in this case in the form of bombs/torpedoes) and range and speed emphasised over protection and defensive capabilities.

In terms of the latter, the G3M was originally designed as a model without any form of defensive weaponry or machine guns, but purely as a bomber craft, with its high-altitude performance being regarded sufficient to evade enemy anti-aircraft guns and its high speed in combination with the planned high performance Mitsubishi A5M fighter envisaged as an armed escort being considered sufficient to counter any form of enemy fighters. Even in the low-speed, low-level role of torpedo bomber, the superior fighter escort - combined with the G3M's high speed - was considered sufficient against any form of ship-based AA guns or carrier-based fighters.

The lightweight structure and complete lack of defensive machine guns and the additional crew necessary to operate them (features in the early prototype design) were considered essential to maintain the speed and high-altitude performance of the G3M with a heavy payload. Even after the modified final prototype, which did include three defensive machine gun emplacements, the G3M kept its lightweight structure and lacked any form of defensive armour or self-sealing fuel tanks, as these were considered to retard speed and altitude. This trait in Japanese bomber/fighter design manifested itself again in its successor, the G4M, which was so heavily designed to accommodate fuel and bombing armament for long-range strikes at the expense of defence that its vulnerability to fighters and ground/surface gunfire earned it the unofficial nickname of "one shot lighter" by Allied fighter pilots, and "Hamaki" ("[flying] cigar") by its own Japanese crews.

The bombsight used in the G3M was primitive compared to the mechanisms used in the G3M's contemporaries such as the B-24 Liberator and Heinkel He 111. Aside from the limited precision necessary in its naval role as a long-range torpedo bomber against Allied naval fleets, the G3M frequently operated with other G3M units in massive "wave" formations, this became a numerical strategy to eliminate the need for singular precision-based bombing and this alternative tactic resulted in horrendous damage and death figures to civilians and civilian population centres from the aerial bombing campaigns against metropolitan targets in China and the Allied Asia-Pacific region.

Later the Nakajima Company redesigned the G3M into the improved G3M3 (Model 23) with more powerful engines and increased fuel capacity. This version was only manufactured by Nakajima, being the most rapidly produced in wartime. This version entered service in 1941, and was maintained in service for two years, and later used in 1943 alongside the G3M2s for long-range maritime reconnaissance with radar, due to its excellent long-range performance. Other G3M derivations were the transport versions, G3M-L and L3Y, the latter built by Yokosuka.

Operational history

The G3M flew for first time in 1935, taking off from a Nagasaki airfield belonging to Mitsubishi Heavy Industries and landing at Haneda Airport on the outskirts of Tokyo. The G3M first saw combat in Japan's expansionist campaigns on the Chinese mainland in what became known as the Second Sino-Japanese War, where the G3M was able to exploit its long-range capability when, during August-November 1937, the "1st Rengo Kokutai" (a special unit) was established, operating alongside the "Kanoya" and "Kizarazu Kokutai" based in Taipei, Formosa, Omura, Kyūshū and Jeju Island. On August 14 of that same year forty-two "Nells" and seven Hiro G2H1s, escorted by 12 Nakajima A4Ns and 12 Mitsubishi A5Ms of the "2nd Rengo Kokutai" (a unit consisting of the 12th and 13th Kokutai), departed from their bases to cross the East China Sea, for the bombing of Hangchow and Kwanteh, and performed amongst others actions of terror bombing in coastal and inland targets in China, including the bombing during the Battle of Shanghai and Nanjing. Thus, while it was the first transoceanic bomber in air war history, it also had the dubious distinction of being the first mass-produced bomber aircraft to wage terror bombing indiscriminately on civilians. Later, from bases in occupied Chinese territories, it took part in the strategic carpet bombing of the Chinese heartland, its combat range being sufficient to cover the elongated distances involved. Most notably, it was involved in the round-the-clock Bombing of Chongqing.

When the Pacific War erupted in 1941, after the Bombing of Pearl Harbor, the G3M was by this time considered to be antiquated but still 3 front-line units (the 22nd to 24th Koku Sentai) were operating a total of 204 G3M2s in four Kokutai (Naval Air Corps) in the central Pacific and of these 54 aircraft from the Takao Kokutai were deployed from Formosa in the opening of the Battle of the Philippines. On the 8th of December 1941, (7th across the International Date Line), G3Ms from the Mihoro Kokutai struck Singapore City from bases in occupied Vietnam as one of many air raids during the Battle of Singapore, resulting in thousands of British and Asiatic civilians dead. Wake Island was similarly bombed by G3Ms from the Chitose Kokutai on the first day of the war, with both civilian and US Navy infrastructure being heavily damaged on the ground.

The G3M was famous for taking part in the sinking of two British capital ships with the more advanced Mitsubishi G4M "Betty", on 10 December 1941. "Nells" from the Genzan Kokutai provided important support during the attack on the HMS Prince of Wales and Repulse (Force Z) near the Malayan coast. Prince of Wales and Repulse were the first two battleships ships ever sunk exclusively by air attack while at sea during war.

A G3M of the Mihoro Air Group was involved in a dogfight with a Consolidated PBY Catalina flying boat of No. 205 Squadron RAF near the Anambas Islands on 25 December 1941, in which the Catalina was shot down.

The attack on Darwin, Australia on February 18, 1942, by 188 Japanese aircraft, included 27 G3Ms of the 1. Kokutai (1st Air Group) based at Ambon, in the Dutch East Indies (Indonesia). The "Nells" attacked alongside 27 G4Ms. These bombers followed an 81-strong first wave of Mitsubishi A6M Zero fighters, Aichi D3A dive bombers and Nakajima B5N torpedo bombers.

From 1943, the majority of "Nells" served as glider tugs, aircrew and paratroop trainers and for transporting high-ranking officers and VIPs between metropolitan islands, occupied territories and combat fronts until the end of the war.
