Betty Bomber
The Mitsubishi G4M is a twin-engine, land-based medium bomber formerly manufactured by the Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and operated by the Air Service (IJNAS) of the Imperial Japanese Navy from 1940 to 1945. Its official designation is and was commonly referred to by Japanese Navy pilots as due to the cylindrical shape of its fuselage and its tendency to ignite after a hit. The Allied reporting name was "Betty". Designed to a strict specification to succeed the Mitsubishi G3M already in service, the G4M boasted very good performance and excellent range and was considered the best land-based naval bomber at the time. 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. The G4M was officially adopted on 2 April 1941, but the aforementioned problems would prove to be a severe drawback, often resulting in heavy losses; Allied fighter pilots n ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Self-sealing Fuel Tanks
A self-sealing fuel tank (SSFT) is a type of fuel tank, typically used in aircraft fuel tanks or fuel bladders, that prevents them from leaking fuel and igniting after being damaged. Typical self-sealing tanks have layers of rubber and reinforcing fabric, one of vulcanized rubber and one of untreated natural rubber, which can absorb fuel when it comes into contact with it. When a fuel tank is punctured the fuel seeps into these layers, causing the untreated layer to swell, closing and thus sealing the puncture. A similar concept is also employed for making self-sealing run-flat tires. History World War I George J. Murdock applied for the patent "War Aeroplane Fuel Tanks" on February 7, 1917 but was temporarily blocked by an order of the Federal Trade Commission, on February 6, 1918, to keep any discussion or publication of the invention secret. The order was rescinded by the United States Patent Office on September 26, 1918 and Murdock was eventually granted "Self-Puncture ...

Mitsubishi G4M Cockpit 1945
The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group traces its origins to the Mitsubishi zaibatsu, a unified company that existed from 1870 to 1946. The company, along with other major zaibatsu, was disbanded during the occupation of Japan following World War II by the order of the Allies. Despite the dissolution, the former constituent companies continue to share the Mitsubishi brand and trademark. While the group of companies engages in limited business cooperation, most notably through monthly "Friday Conference" executive meetings, they remain formally independent and are not under common control. The three main entities (''gosanke'') are Mitsubishi UFJ Financial Group (the largest bank in Japan), Mitsubishi Corporation (a general trading company), and Mitsubishi Heavy Industries (a diversified manufacturing company). A 2020 estimate concluded that all the Mitsubishi companies co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Aircraft
Transport aircraft is a broad category of aircraft that includes: * Airliners, aircraft, usually large and most often operated by airlines, intended for carrying multiple passengers or cargo in commercial service * Cargo aircraft or freighters, fixed-wing aircraft designed or converted for the carriage of goods, rather than passengers, lacking in passenger amenities and generally featuring one or more large doors for loading cargo; also known as freight aircraft, freighters, airlifters, or cargo jets. * Mail planes, airplanes used for carrying mail * Military transport aircraft, airplanes or helicopters used to deliver troops, weapons, and military equipment, usually outside of the commercial flight routes in uncontrolled airspace, and employed historically to deliver airborne forces and tow military gliders; sometimes also called military cargo aircraft. {{Sia ...

Escort Fighter
The escort fighter was a concept for a fighter aircraft designed to escort bombers to and from their targets. An escort fighter needed range long enough to reach the target, loiter over it for the duration of the raid to defend the bombers, and return. A number of twin-engined heavy fighters with high fuel capacity were designed for escort duties prior to the outbreak of World War II. Such heavy fighters largely failed in their intended escort role during the war, as they were commonly outmaneuvered by more agile single-engined fighters. As the war progressed, longer-range fighter designs and the use of drop tanks allowed single-engined fighters to perform escort duties. In the post-war era the introduction of jet engines and their inherent short range made escort fighters very difficult to build. The related concept of a penetration fighter emerged briefly in the 1950s and again in the 1960s, but did not result in any production aircraft. Parasite fighters—small aircraf ...

Mitsubishi G6M1
The Mitsubishi G6M was a Japanese heavy fighter developed during World War II for use as an escort fighter or escort gunship (similar to the American YB-40) by the Imperial Japanese Navy Air Service. It was a derivative of the Mitsubishi G4M, a medium bomber, with added forward-firing offensive cannon armament, additional armour, and an increased crew size of ten. Despite its intended role and largely due to poor performance, the G6M1 never saw combat as an escort fighter; instead, the produced units served as training and transport aircraft. History Background On 23 October 1939, the Mitsubishi G4M bomber took its first flight. Although the aircraft demonstrated excellent performance, it was not immediately put into serial production. This delay stemmed from the ongoing Second Sino-Japanese War (1937–1945), during which the Imperial Japanese Navy relied heavily on its existing Mitsubishi G3M bombers for combat operations in China. The navy prioritized maintaining the su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Fighter
A heavy fighter is an historic category of fighter aircraft produced in the 1930s and 1940s, designed to carry heavier weapons or operate at longer ranges than light fighter aircraft. To achieve performance, most heavy fighters were twin-engined, and many had multi-place crews; this was in contrast to light fighters, which were typically single-engined and single-crew aircraft. In Germany, these larger fighters were known as ''Zerstörer'' ("destroyers"). The heavy fighter was a major design class during the pre-World War II period, conceived as long-range escort fighters or heavily-armed bomber destroyers. Most such designs failed in this mission, as they could not maneuver quickly enough against single-engine fighters. Most notable among such designs was the Messerschmitt Bf 110, which suffered great losses during the Battle of Britain. An exception was the American Lockheed P-38 Lightning, which proved an effective heavy fighter; even against smaller, lighter, single-engin ...

Yokosuka MXY-7 Ohka
The Yokosuka MXY-7 is a purpose-built, rocket-powered human-guided ''kamikaze'' attack-aircraft deployed by Japan against Allied ships in the Pacific Ocean theater toward the end of World War II. Although extremely fast, the ''Ohka'' had a very short range of , so it had to be carried into action as a parasite aircraft by a much larger bomber that was vulnerable to carrier-borne fighters. In action during the Battle of Okinawa in 1945, ''Ohka''s succeeded in sinking or damaging some escort-vessels and transport ships, but never sank any major warships. The Japanese developed improved versions in an attempt to overcome the aircraft's shortcomings, but they came too late for deployment. Allied personnel referred to the aircraft as "Baka Bombs" ( ''baka'' being a Japanese pejorative term meaning "fool" or "idiot"). Design and development The MXY-7 Navy Suicide Attacker ''Ohka'' was a manned flying bomb that was usually carried underneath a Mitsubishi G4M2e Model 24J "Betty" ...

Mother Ship
A mother ship, mothership or mother-ship is a large vehicle that leads, serves, or carries other smaller vehicles. A mother ship may be a maritime ship, aircraft, or spacecraft. Examples include bomber aircraft, bombers converted to carry experimental aircraft to altitudes where they can conduct their research (such as the B-52 carrying the X-15), or ships that carry small submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atlantis II carrying the DSV Alvin, ''Alvin''). A mother ship may also be used to recover smaller craft, or go its own way after releasing them. A smaller vessel serving or caring for ''larger'' craft is usually called a tender ship, tender. Maritime craft During World War II, the German Type XIV submarine or ''Milchkuh'' (Milk cow) was a type of large submarine used to resupply the U-boats. Mother ships can carry small submersibles and submarines to an area of ocean to be explored (such as the R/V Atlantis (AGOR-25), Atla ...

Battle Of Rennell Island
The took place on 29–30 January 1943. It was the last major naval battle, naval engagement between the United States Navy and the Imperial Japanese Navy during the Guadalcanal Campaign of World War II. It occurred in the South Pacific Area, South Pacific between Rennell Island and Guadalcanal in the southern Solomon Islands. In the battle, Japanese land-based torpedo bombers, seeking to provide protection for the Operation Ke, impending evacuation of Japanese forces from Guadalcanal, made several attacks over two days on U.S. warships operating as a task force south of Rennell Island. In addition to approaching Guadalcanal with the objective of engaging any Japanese ships that might come into range, the U.S. task force was protecting an Allies of World War II, Allied transport ship convoy carrying replacement troops there. As a result of the Japanese air attacks on the task force, the heavy cruiser was sunk, the destroyer was heavily damaged, and the rest of the U.S. task ...

USS Chicago (CA-29)
USS ''Chicago'' (CL/CA-29) was a of the United States Navy that served in the Pacific War, Pacific Theater in the early years of World War II. She was the second US Navy ship to be named after the city of Chicago. After surviving a midget submarine attack at Sydney Harbour defences, Sydney Harbour and serving in battle at the Battle of the Coral Sea, Coral Sea and Battle of Savo Island, Savo Island in 1942, she was sunk by Japanese aerial torpedoes in the Battle of Rennell Island, in the Solomon Islands, on 30 January 1943. Construction ''Chicago'' was Ship naming and launching, launched on 10 April 1930 by Mare Island Naval Shipyard under the supervision of Naval constructor Charles W. Fisher Jr., sponsored by Miss E. Britten; and ship commissioning, commissioned on 9 March 1931. She was originally classified as a light cruiser, CL-29, because of her thin armor. From 1 July 1931, ''Chicago'' was redesignated a heavy cruiser, CA-29, because of her 8-inch guns in accordance with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
