The AS-90 ("Artillery System for the 1990s"), known officially as Gun Equipment 155 mm L131, is an armoured self-propelled artillery used by the British Army. It can fire standard charges up to 24.7 km (15.3 mi) using 39-calibre long barrel and 30 km (19 mi) with 52-calibre long barrel. [ 2 ]
In genetic engineering, a gene gun or biolistic particle delivery system is a device used to deliver exogenous DNA , RNA, or protein to cells. By coating particles of a heavy metal with a gene of interest and firing these micro-projectiles into cells using mechanical force, an integration of desired genetic information can be introduced into ...
The Mark 7 gun was originally intended to fire the 2,240-pound (1,020 kg) Mark 5 armor-piercing shell. However, the shell-handling system for these guns was redesigned to use the "super-heavy" 2,700-pound (1,200 kg) APCBC (Armor Piercing, Capped, Ballistic Capped) Mark 8 shell before any of the Iowa-class battleship's keels

Benjamin Robins (1707 – 29 July 1751) was a pioneering British scientist, Newtonian mathematician, and military engineer.. He wrote an influential treatise on gunnery, for the first time introducing Newtonian science to military men, was an early enthusiast for rifled gun barrels, and his work had substantive influence on the development of artillery during the latter half of the eighteenth ...
The A-10 engines were initially susceptible to flameout when subjected to gases generated in the firing of the gun. When the GAU-8 is being fired, the smoke from the gun can make the engines stop, and this did occur during initial flight testing. [4] Gun exhaust is essentially oxygen-free, and is capable of causing flameouts of gas turbines ...
A ballistic body is a free-moving body with momentum, which can be subject to forces such as those exerted by pressurized gases from a gun barrel or a propelling nozzle, normal force by rifling, and gravity and air drag during flight.
The mentioned ballistic missile is among third-generation long-range missiles indigenously developed/manufactured by military experts at the IRGC's Aerospace Division. [157] Rezvan - Liquid fueled missile with a 1,400 km range. [158] Unnamed anti-ship ballistic missile with a reported range of 1500 km and a speed of 8 Mach. [159]
