Haubits FH77
Fälthaubits 77 (Swedish "Field Howitzer 77") or FH77 is a Swedish 155 mm howitzer, developed and manufactured by Bofors. It is also colloquially known as the Bofors gun in India. There were several versions, the original (sometimes referred to as Haubits 77 A) with a 38 calibre barrel and sliding block mechanism, the export version FH77 B version with a 39 calibre barrel and an interrupted ogival screw breech. For the demonstrator of the Archer Artillery System, some FH77A were modified into FH 77 AD L/45, while the series production were FH77Bs rebuilt into FH77 BW L/52. The carriage was also used for the "12 cm rörlig kustartilleripjäs m/80 KARIN", used in the Swedish coastal artillery. Design and development History In the 1960s, Sweden started to look for a replacement for the French Obusier de 155 mm Modèle 50 (''Haubits'' F). The American M109 self-propelled howitzer was offered and tested. Though the price was low, the Swedish Arms Administration found that the ...

FH70
The FH70 (field howitzer for the 1970s) is a towed howitzer in use with several nations. History In 1963, NATO agreed a NATO Basic Military Requirement 39 for close support artillery, either towed or tracked. Subsequently, Germany and UK started discussions and design studies and in 1968 established agreed operational characteristics for a towed 155 mm close support gun. Italy became a party to the agreement in 1970. Key requirements were: * A detachable auxiliary power unit (APU) * An unassisted range of ; an assisted range of * A burst capability of three rounds in 15–20 seconds, six rounds per minute for a short period and two rounds per minute sustained * The ablility to fire all 155 mm munitions in NATO service, plus a new range of ammunition. The two national authorities had overall responsibility for R&D, and Vickers Ltd was the co-ordinating design authority. They were also the design authority for the carriage and Rheinmetall GmbH was the authority fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M109 Howitzer
The M109 is an American 155 mm turreted self-propelled howitzer, first introduced in the early 1960s to replace the M44. It has been upgraded a number of times, most recently to the M109A7. The M109 family is the most common Western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions. The M109 has a crew of four: the section chief/commander, the driver, the gunner, and the ammunition handler/loader. The chief or gunner aims the cannon left or right (deflection) and up and down (quadrant). The British Army replaced its M109s with the AS-90. Several European armed forces have or are currently replacing older M109s with the German PzH 2000. Upgrades to the M109 were introduced by the U.S. (see variants) and by Switzerland (KAWEST). With the cancellation of the U.S. Crusader and Non-Line-of-Sight Cannon, the M109A6 ("Paladin") will likely remain the principal self-propelled howitzer for the U.S. until the new M1299 enters service.

Ramjet
A ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an assisted take-off like a rocket assist to accelerate it to a speed where it begins to produce thrust. Ramjets work most efficiently at supersonic speeds around and can operate up to speeds of . Ramjets can be particularly useful in applications requiring a small and simple mechanism for high-speed use, such as missiles. The US, Canada, and UK had widespread ramjet powered missile defenses during the 1960s onward, such as the CIM-10 Bomarc and Bloodhound. Weapon designers are looking to use ramjet technology in artillery shells to give added range; a 120 mm mortar shell, if assisted by a ramjet, is thought to be able to attain a range of . They have also been used successfully, though not efficiently, as tip jets on the ends of helicopt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gun Layer
A gun is a ranged weapon designed to use a shooting tube (gun barrel) to launch projectiles. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns/cannons, spray guns for painting or pressure washing, projected water disruptors, and technically also flamethrowers), gas (e.g. light-gas gun) or even charged particles (e.g. plasma gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Taser guns, spearguns and harpoon guns). A large-caliber gun is also called a ''cannon''. The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within the barrel tube, produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of the tube, imparti ...

Jerrycan
A jerrycan (also written as jerry can or jerrican) is a robust liquid container made from pressed steel (and more recently, high density polyethylene). It was designed in Germany in the 1930s for military use to hold of fuel, and saw widespread use by both Germany and the Allies during the Second World War. The development of the jerrycan was a significant improvement on earlier designs, which required tools and funnels to use, and it contained many innovative features for convenience of use and robustness. Today similar designs are used worldwide for fuel and water containers, in both military and civilian contexts. The designs usually emulate the original steel design, though some are also produced in plastic. History The name of the jerrycan refers to its German origins, '' Jerry'' being slang for Germans. The design was reverse engineered and subsequently copied, with minor modifications, by the Allies during the Second World War. German invention The ''Wehrmacht ...
