Ogbunigwe
Ogbunigwe also called Ojukwu Bucket was a series of weapons systems including command detonation mines, improvised explosive devices, and rocket propelled missiles, mass-produced by the Republic of Biafra and used against Nigeria between 1967 and 1970 in the Biafran War. History At the outbreak of hostilities, the Biafran armed forces were poorly equipped as compared to the Nigerian army with arms and ammunition being in short supply. This imbalance in power was intensified in the course of the war. Biafran scientists, prominently from the University of Nigeria Nsukka (then University of Biafra), formed the Research and Production (RAP) Agency of Biafra which included a Weapons Research and Production Group. Headed by Colonel Ejike Obumneme Aghanya, it was the aim and purpose of this group to develop an indigenous arms industry and they soon started with the production of ammunition, grenades and armoured cars. Their most effective and infamous product was the Ogbunigwe of whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejike Obumneme Aghanya
Ejike Ebenezer Obumneme Aghanya (27 November 1932 – 3 July 2020) was a military officer and electrical engineer who served in the Nigerian Army and the Biafran Armed Forces, retiring as a colonel. Accused of involvement in the 1966 Nigerian coup d'état he was arrested and imprisoned without trial until the outbreak of the Nigerian Civil War where he served on the side of Biafra, holding key positions in the Biafran Armed Forces. He was the head of the Biafran Agency for Research and Production (RAP) which produced bombs, rockets, missiles (collectively called Ogbunigwe), as well as ammunition, armored vehicles, telecommunication gadgets and petroleum refineries among others for the Biafran Armed Forces. Later he was the Chief of Staff of the Biafran Organisation of Freedom Fighters (BOFF) which was the guerrilla warfare and special operations arm of the Biafran Armed Forces. He also served as Battalion Commander, 44th Electrical and Mechanical Engineer Battalion Biafran Army ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abagana Ambush
The Abagana Ambush (March 31, 1968) was an ambush by Biafran guerrilla troops led by Major Jonathan Uchendu that wiped out the Nigerian 2 Division. Of the 6,000 Nigerian troops ambushed, only a very small number survived, including the 2nd Division's commander, General Murtala Muhammed. Background On 4 October 1967, the Nigerian 2nd Division began bombarding Onitsha and continued the assault for eight days, before a 10 boat armada crossed the Niger River into the city. The occupying Nigerians didn't pursue retreating Biafran soldiers and instead opted to loot and burn the Onitsha market to the ground. The Biafran 11th and 18th Battalions under Major Joseph Achuzie and Col. Assam Nsudoh formed a pincer and attacked Onitsha from two directions, capturing and killing most Nigerian soldiers. In December 1967 the Nigerian 2nd Division and the 6th Battalion crossed the Niger River at Idah and began making their way towards Onitsha, finally capturing the city after several attempts. ...

Biafran War
The Nigerian Civil War (6 July 1967 – 15 January 1970), also known as the Nigerian–Biafran War or the Biafran War, was a civil war fought between Nigeria and the Republic of Biafra, a secessionist state which had declared its independence from Nigeria in 1967. Nigeria was led by General Yakubu Gowon, while Biafra was led by Lieutenant Colonel Chukwuemeka "Emeka" Odumegwu Ojukwu. Biafra represented the nationalist aspirations of the Igbo ethnic group, whose leadership felt they could no longer coexist with the federal government dominated by the interests of the Muslim Hausa-Fulanis of Northern Nigeria. The conflict resulted from political, economic, ethnic, cultural and religious tensions which preceded the United Kingdom's formal decolonization of Nigeria from 1960 to 1963. Immediate causes of the war in 1966 included a military coup, a counter-coup, and anti-Igbo pogroms in Northern Nigeria. Control over the lucrative oil production in the Niger Delta also played a vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-ship Missile
An anti-ship missile (AShM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. The first anti-ship missiles, which were developed and built by Nazi Germany, used radio command guidance.https://airandspace.si.edu/collection-objects/bomb-guided-fritz-x-x-1/nasm_A19840794000#:~:text=The%20Fritz%20X%2C%20also%20known,the%20Henschel%20Hs%20293%20missile. These saw some success in the Mediterranean Theatre during 1943–44, sinking or heavily damaging at least 31 ships with the Henschel Hs 293 and more than seven with the '' Fritz X'', including the Italian battleship ''Roma'' and the light cruiser . A variant of the HS 293 had a TV cam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American B-25 Mitchell
The North American B-25 Mitchell is an American medium bomber that was introduced in 1941 and named in honor of Major General William "Billy" Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included several limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber. Design and development The Air Corps issued a specification for a medium bomber in March 1939 that was capable of carrying a payload of over at North American Aviation used its NA-40B design to develop the NA-62, which competed for the medium bomber contract. No YB-25 was available for prototype service tests. In September 1939, the Air Corps ordered the NA-62 into production as the B-25, along with the ...

Shock Wave
In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and density of the medium. For the purpose of comparison, in supersonic flows, additional increased expansion may be achieved through an expansion fan, also known as a Prandtl–Meyer expansion fan. The accompanying expansion wave may approach and eventually collide and recombine with the shock wave, creating a process of destructive interference. The sonic boom associated with the passage of a supersonic aircraft is a type of sound wave produced by constructive interference. Unlike solitons (another kind of nonlinear wave), the energy and speed of a shock wave alone dissipates relatively quickly with distance. When a shock wave passes through ...

Air Burst
An air burst or airburst is the detonation of an explosive device such as an anti-personnel artillery shell or a nuclear weapon in the air instead of on contact with the ground or target. The principal military advantage of an air burst over a ground burst is that the energy from the explosion (as well as any shell fragments) is distributed more evenly over a wider area; however, the peak energy is lower at ground zero. History Air burst artillery has a long history. The shrapnel shell was invented by Henry Shrapnel of the British Army in about 1780 to increase the effectiveness of canister shot. It was widely used by the time of the War of 1812 and stayed in use until it was superseded during the First World War. Modern shells, though sometimes called "shrapnel shells", actually produce fragments and splinters, not shrapnel. Air bursts were used in the First World War to shower enemy positions and men with shrapnel balls to kill the largest possible number with a sing ...

Mig 17
The Mikoyan-Gurevich MiG-17 (russian: Микоян и Гуревич МиГ-17; NATO reporting name: Fresco) is a high-subsonic fighter aircraft produced in the Soviet Union from 1952 and was operated by air forces internationally. The MiG-17 was license-built in China as the Shenyang J-5 and Poland as the PZL-Mielec Lim-6. The MiG-17 is still being used by the North Korean air force in the present day and has seen combat in the Middle East and Asia. The MiG-17 was an advanced modification of the MiG-15 aircraft produced by the Soviet Union during the Korean War. Production of the MiG-17 was too late for use in that conflict and was first used in the Second Taiwan Strait Crisis in 1958. While the MiG-17 was designed to shoot down slower American bombers, it showed surprising success when used by North Vietnamese pilots to combat American fighters and fighter-bombers during the Vietnam War, nearly a decade after its initial design. This was due to the MiG-17 being more agile and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigerian Air Force
The Nigerian Air Force (NAF) is the air branch of the Nigerian Armed Forces. It is the youngest branch of the Nigerian Armed Forces. It is one of the largest in Africa, consisting of about 15,000 personnel and aircraft including eight Chinese Chengdu F-7s, 12 Dassault-Dornier Alpha Jets, three JF-17 Thunder Block II and 12 Super Tucano aircraft, 24 M-346 FAs on order, Helicopter gunships, armed attack drones, and military transport aircraft. History Although an Air Force was originally proposed in 1958, many lawmakers preferred to rely on the United Kingdom for air defense. But during peacekeeping operations in Congo and Tanganyika, the Nigerian Army had no air transport of its own, and so in 1962, the government began to recruit cadets for pilot training in various foreign countries, with the first ten being taught by the Egyptian Air Force. 1960s The Nigerian Air Force was formally established on 18 April 1964 with the passage of the Air Force Act 1964 by the National Ass ...

Ferret Armoured Car
The Ferret armoured car, also commonly called the Ferret scout car, is a British armoured fighting vehicle designed and built for reconnaissance purposes. The Ferret was produced between 1952 and 1971 by the UK company Daimler. It was widely used by regiments in the British Army, as well as the RAF Regiment and Commonwealth countries throughout the period. History The Ferret was developed in 1949 as a result of a British Army requirement issued in 1947. 'Light reconnaissance cars' existed during the Second World War, notably the Daimler Dingo. Given its experience with the successful Dingo (6,626 produced and one of two British AFVs produced throughout WWII) Daimler was awarded a development contract in October 1948, and in June 1950 the first prototype of the Car, Scout, 4×4, Liaison (Ferret) Mark 1 was delivered. Designated the FV 701(C), it was one of several versions resembling the original Daimler scout cars, and represented the basic model Ferret. This shared many si ...

Alvis Saladin
The FV601 Saladin is a six-wheeled armoured car developed by Crossley Motors and later manufactured by Alvis. Designed in 1954, it replaced the AEC Armoured Car in service with the British Army from 1958 onward. The vehicle weighed 11 tonnes, offered a top speed of 72 km/h, and had a crew of three. Saladins were noted for their excellent performance in desert conditions, and found favour with a number of Middle Eastern armies accordingly.''Middle East Economic Digest (1968)''. Collard, Elizabeth, Volume 12 pp. 131—173. They were armed with a 76 mm low-pressure rifled gun which fired the same ammunition as that mounted on the FV101 Scorpion. The Saladin also spawned an armoured personnel carrier counterpart, the Alvis Saracen. Despite the vehicle's age and dated design, it is still in use in a number of countries in secondary roles. History Development Following the end of the Second World War, the British Army issued a requirement for a new, 6×6 wheeled armoured v ...
