The MB 2 was first flown by Captain Valentine Baker at Harwell on 3 August 1938 and initially tested with markings MB-1 (G-AEZD not carried). The Aeroplane stated, "[I]n spite of its fixed undercarriage, the MB 2 had a performance as good as that of contemporary fighters and a capacity for quick and cheap production by the simplicity of its structure and easy assembly".
A gyro gunsight (G.G.S.) is a modification of the non-magnifying reflector sight in which target lead (the amount of aim-off in front of a moving target) and bullet drop are calculated automatically. The first examples were developed in Britain just before the Second World War for use during aerial combat , and more advanced models were common ...
Fire from the eight machine guns of a Hawker Hurricane is shown converging to a point, then diverging. (Drawing not to scale.) In aerial gunnery, gun harmonisation, convergence pattern, convergence zone, convergence point or bore-sight point refers to the aiming of fixed guns or cannon carried in the wings of a fighter aircraft.
Tang sights were mounted behind the action of the rifle, and provided a very long sight radius, and had to be unfolded for use, though rifles with tang sights often had open sights as well for close range use. Tang sights often had vernier scales, allowing adjustment down to a single minute of arc over the full range of the sight.
Reflector sights were first used as a weapon sight in German aircraft towards the end of World War I. Over the years they became more sophisticated, adding lead computing gyroscopes and electronics (the World War II Gyro gunsight ) [ 8 ] radar range finding and other flight information in the 1950s and 1960s, eventually becoming the modern head ...
Each bullet position is measured horizontally and vertically from the point of aim, and sights are adjusted to compensate for the mean horizontal distance and mean vertical distance from the point of aim. [8] After the sights have been adjusted, more shots may be fired from a cool barrel forming another group to verify that sight adjustment ...
The MB-2 tow tractor is an aircraft towing vehicle used by the United States and Allied Air Forces. There are several models of the MB-2 tractor, with weight characteristics between 40,000 and 54,000 lb (18,000 and 24,000 kg).
The sight is designed for use with the M16/M4 family of rifles, but can be mounted on any weapon fitted with an upper Picatinny rail. It is also NVG-compatible—the aiming dot is still visible through night vision scopes and goggles. The Army's M68 designation was also applied to a later version of the sight, the Aimpoint CompM4.
