The Tank Medium No. 2 Experimental Vehicle FV4202 also known as the 40-ton Centurion [1] was a technology test bed developed by British company Leyland Motors between 1955 and 1956. It was used to develop various concepts later used in the Chieftain main battle tank.
Test coverage in the test plan states what requirements will be verified during what stages of the product life. Test coverage is derived from design specifications and other requirements, such as safety standards or regulatory codes, where each requirement or specification of the design ideally will have one or more corresponding means of verification.
For example, the 7.5 cm Pak 40 L/46 antitank gun and the 7.5 cm KwK 40 L/48 tank gun fired the same projectile, even though they had completely different cartridge cases. Different versions of the shell were made, but the changes were usually minor. For instance, in the 88 mm Pzgr. 39-1 version the quality of steel was improved.
The civilian production version, or Series 40, was slightly refined over the prototype, with more speed and a roomier cabin. North American then stretched the design by 3 feet 2 inches (0.97 m), providing greater cabin space, and marketed it as the Series 60 , which was certificated in April 1967.

Whiteprint describes a document reproduction produced by using the diazo chemical process. [1] It is also known as the blue-line process since the result is blue lines on a white background. It is a contact printing process that accurately reproduces the original in size, but cannot reproduce continuous tones or colors.
The 1996 Navy Visibility and Management of Operating and Support Costs (VAMOSC) study determined the annual operating cost of a Virginia-class cruiser at $40 million, compared to $28 million for a Ticonderoga-class cruiser, or $20 million for an Arleigh Burke-class destroyer, the latter two classes designed with the much more capable Aegis ...
