Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors.
Early Snow S-2A of 1959 with open cockpit and roll-over protection bar at Santa Fe, New Mexico, June 1997, in pseudo-USAAF markings. The Thrush, designed by Leland Snow, first flew in 1956 and before long was being produced in series as the S-2 by the company he founded, Snow Aeronautical. [1]
Modern 120 mm tank gun shells. KE penetrators for modern tanks are commonly 2–3 cm (0.787–1.18 in) in diameter, and can approach 80 cm (31.5 in) long. As more structurally efficient penetrator-sabot designs are developed their length tends to increase, in order to defeat even greater line-of-sight armour depth.
The 105×617mm (4.1 inch), also known as 105×617mmR, is a common, NATO-standard, tank gun cartridge used in 105 mm guns such as those derived from the Royal Ordnance L7. The 105×617mmR cartridge was originally developed from the 84 mm (3.3 in) calibre Ordnance QF 20-pounder 84 × 618R cartridge as part of the development of the L7 105 mm ...

It was followed by a lightweight version designated the CAP 20L which in turn was replaced by the CAP 21 with more advanced wing. The CAP 20 was developed as a single-seat acrobatic version of the company's CAP 10; it was used by the French Air Force's flying demonstration team, Equipe de Voltige Aerienne. The CAP 20L is externally similar to ...
In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i.e., bounded by a single plane. If the plane passes through the center of the sphere (forming a great circle ), so that the height of the cap is equal to the radius of the sphere, the spherical ...
For ground vehicles, mines are dispensed 25 to 60 metres (82 to 197 feet) from the vehicle at ground speeds of 5 to 55 mph (8 to 89 km/h). A constant speed is maintained while the mines are being dispensed so as to attain a consistent mine density. The average time to emplace one load (160 canisters) is 10 minutes.
