120×570mm NATO tank ammunition (4.7 inch), also known as 120×570mmR, is a common, NATO-standard (STANAG 4385), tank gun semi-combustible cartridge used by 120mm smoothbore guns, superseding the earlier 105×617mmR cartridge used in NATO-standard rifled tank guns.
The M829A1 (nicknamed the "Silver Bullet" by Operation Desert Storm tank crews) proved itself in 1991 against Iraqi T-55 and T-72M tanks during Operation Desert Storm.The M829A1 round weighs 20.9 kg (46 lb) and has an overall length of 984 mm (38.7 in).
An important parameter in wet scrubbing systems is the rate of liquid flow. It is common in wet scrubber terminology to express the liquid flow as a function of the gas flow rate that is being treated. This is commonly called the liquid-to-gas ratio (L/G ratio) and uses the units of gallons per 1,000 actual cubic feet or litres per cubic metre ...
The M970 Semi-Trailer Refueler is a 5,000-U.S.-gallon (19,000 L; 4,200 imp gal) fuel dispensing tanker designed for under/overwing refueling of aircraft. It is equipped with a filter/separator, recirculation system and two refueling systems, one for underwing and one for overwing servicing.
In September 1954, out of many submitted plans, two main examples were chosen – the T95, and the T96, which used a larger and heavier gun with a 105 mm round. Both tanks used smooth-bore barrels with fixed mounts and no recoil systems. In November 1956, it was decided that nine tanks would be produced. Four of them would be original T95s.
Standard fuel bladder tanks sizes range from 100-US-gallon (380 L) to 200,000-US-gallon (760,000 L) capacities and larger. Custom fuel storage bladders and cells are available, although at sizes exceeding 50,000 US gallons (190,000 L) there is an increased spill risk.
Development of a tank classification system started in World War I, when tanks were separated into light tanks and tankettes, medium tanks, and heavy tanks, based on size and weight. Heavy tanks were required to be large to cross trenches, and consequently weighed a lot. Medium tanks were smaller and had help to cross trenches so weighed less.
The gun is fully stabilised, and can fire a variety of types of rounds, such as the German DM43 APFSDS-T anti-tank round, which is said to be able to penetrate 450 millimeters (18 in) [74] [citation needed] of steel armour at a range of 2,000 metres (2,200 yd), [75] and the German DM12 high-explosive anti-tank (HEAT).
