A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor.
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 Imperial Japanese Navy from 1940 to 1945. Its official designation is Mitsubishi Navy Type 1 attack bomber and was commonly referred to by Japanese Navy pilots as Hamaki due to the cylindrical shape of its fuselage and its tendency to ignite after a hit. The Allied reporting name was "Betty".
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
The Mitsubishi Ki-67Hiryū was a twin-engine bomber produced by Mitsubishi Aircraft Company and used by the Imperial Japanese Army Air Service and Imperial Japanese Navy Air Service in World War II. While its original official designation was "Army Type 4 Heavy Bomber", in all of its key parameters, the Ki-67 was similar to the contemporaneous medium bombers of other countries. Japanese Navy variants included the P2M and Q2M.
The Kyūshū Q1WTōkai was a land-based anti-submarine patrol bomber aircraft developed for the Imperial Japanese Navy in World War II. The Allied reporting name was Lorna. Although similar in appearance to the German Junkers Ju 88 medium bomber, the Q1W was a much smaller aircraft with significantly different design details.
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is fox three.
The Kawasaki Ki-45 Toryu was a two-seat, twin-engine heavy fighter used by the Imperial Japanese Army in World War II. The army gave it the designation "Type 2 Two-Seat Fighter"; the Allied reporting name was "Nick". Originally serving as a long-range escort-fighter, the design — as with most heavy fighters of the period — fell prey to smaller, lighter, more agile single-engine fighters. As such, the Ki-45 instead served as a day and nighttime interceptor and strike fighter.
The Mitsubishi F-1 is a Japanese swept-wing, single-seat, twin-engine supersonic strike aircraft that was in service with the Japan Air Self-Defense Force (JASDF) from 1978 to 2006. It was Japan's first domestically designed and built supersonic combat aircraft, jointly developed by Mitsubishi Heavy Industries. It is essentially a T-2 trainer airframe modified for a dedicated anti-ship and ground attack role.
The ASM-N-2 Bat was a United States Navy World War II radar-guided glide bomb which was used in combat beginning in April 1944. It was developed and overseen by a unit within the National Bureau of Standards with assistance from the Navy's Bureau of Ordnance, the Massachusetts Institute of Technology, and Bell Telephone Laboratories. It is considered to be the first fully automated guided missile used in combat.
The Mitsubishi Q2M "Tai'yō" design was derived from the Mitsubishi Ki-67-I Hiryū ("Peggy") heavy/torpedo bomber of the Japanese Army and its Naval variant, "Yasukuni". It was ordered for design and construction in the last stages of war.
The Rainbow Codes were a series of code names used to disguise the nature of various British military research projects. They were mainly used by the Ministry of Supply from the end of the Second World War until 1958, when the ministry was broken up and its functions distributed among the forces. The codes were replaced by an alphanumeric code system.
The Type 98 light tank Ke-Ni or Type 98A Ke-Ni Ko was designed to replace the Imperial Japanese Army's Type 95 Ha-Go light tank, Japan's most numerous armored fighting vehicle during World War II. Although designed before World War II began, production did not start until 1942, with 104 being produced by the end of the war in the Pacific.
The Kawasaki Ki-102 or Type 4 Attack Plane was a Japanese warplane of World War II. It was a twin-engine, two-seat, long-range heavy fighter developed to replace the Ki-45 Toryu. Three versions were planned: the Ki-102 Kō day fighter, Ki-102 Otsu ground-attack and Ki-102 Hei night fighter. This aircraft's Allied reporting name was "Randy".
The Mitsubishi I-Gо̄ Model 1 Kо̄, otherwise known as Ki-147 was a radio-guided air to surface missile developed by Japan in World War II. The Imperial Japanese Army's main envisioned role for the platform was for strikes against U.S. and allied ships. The Ki-147 was planned to be installed on Ki-67 heavy bombers which would act as the control platform. The Ki-147 was developed during 1944-1945 along with its sister project of the smaller Kawasaki I-Gо̄ Model 1 Otsu (Ki-148) radio-guided air-to-surface missile and the later Tokyo Imperial University designed I-Gо̄ Model 1 Hei.
The Type 03 Medium-Range Surface-to-Air Missile or SAM-4 or Chu-SAM is a Japanese developed surface-to-air missile system currently in service with the JGSDF. The SAM's vehicle chassis is based on the Kato Works Ltd/Mitsubishi Heavy Industries NK series heavy crane truck. It uses a state-of-the-art active electronically scanned array radar.
Radar in World War II greatly influenced many important aspects of the conflict. This revolutionary new technology of radio-based detection and tracking was used by both the Allies and Axis powers in World War II, which had evolved independently in a number of nations during the mid 1930s. At the outbreak of war in September 1939, both the United Kingdom and Germany had functioning radar systems. In the UK, it was called RDF, Range and Direction Finding, while in Germany the name Funkmeß (radio-measuring) was used, with apparatuses called Funkmessgerät . By the time of the Battle of Britain in mid-1940, the Royal Air Force (RAF) had fully integrated RDF as part of the national air defence.
Funryu were a series of surface-to-air anti-aircraft missiles developed in Japan at the end of the Second World War. The missile's development in the late stages of the war was plagued by organizational problems and cancelled before becoming operational.
