The Vickers MBT is a series of main battle tanks (MBTs) developed as a private venture by British company Vickers-Armstrongs for export.

The Armstrong Siddeley Sapphire is a British turbojet engine that was produced by Armstrong Siddeley in the 1950s. It was the ultimate development of work that had started as the Metrovick F.2 in 1940, evolving into an advanced axial flow design with an annular combustion chamber that developed over 11,000 lbf (49 kN).

Mark D : the Vickers Mk. D was a one-off design built for the Irish Free State and delivered in 1929. It had a more powerful, water cooled, rear mounted, 6-cylinder Sunbeam Amazon petrol engine, developing 170 bhp (130 kW) at 2100 rpm. A 6 pdr gun was fitted and as many as four Vickers .303 (7.7 mm) machine guns. The tank was scrapped in 1940.
Vickers was on this occasion ordered to add armour skirts but keep within the weight limit even if it meant removing armour elsewhere; A6E3 had also been ordered. A6E1, A6E2 and A6E3 were fitted with an Armstrong Siddeley air-cooled V8 180 hp engine giving a maximum speed of 26 mph (42 km/h).
The Littlejohn adaptor/APCNR combination gave the 2 pounder a similar effect as the armour-piercing discarding sabot round used with the much larger and heavier QF 6 pounder gun. The muzzle velocity of the APSV Mark II shell was 1,143 m/s compared with the 792 m/s of the normal 1.2 kg APCBC shell.
The Vickers-Armstrongs V-1000 was a proposed jet-powered cargo aircraft that was designed to meet a requirement issued by the British Ministry of Supply which sought a strategic transport for the Royal Air Force (RAF) to support its strategic bomber fleet, particularly the V-bombers.
