M795
The M795 155mm projectile is the US Army and US Marine Corps' standard 155mm High Explosive (HE) projectile for howitzers. It is a bursting round with fragmentation and blast effects. The M795 is designed to be a more lethal and have a longer range than that of the M107. A welded band replaces the swaged rotating band of the M107, allowing the M795 to be fired with M119 or M203 propelling charges, increasing range by . The explosive payload was also improved, as was the fragmentation pattern, giving 30% higher lethality. Description The M795 is a 155mm high- fragmentation, steel (HF1)-body projectile filled with of TNT and weighing approximately . The high-fragmentation steel body is encircled by a gilding metal rotating band, making it compatible with 3W through 8S (M3A1 through M203A1) zone propelling charges across all current 155mm howitzers. The projectile is packaged on a metal pallet with a shock-attenuating lifting plug and flexible rotating band cover. The M795 projec ...

GPS Block III
GPS Block III (previously Block IIIA) consists of the first ten GPS satellite blocks, GPS III satellites, which will be used to keep the Navstar Global Positioning System operational. Lockheed Martin designed, developed and manufactured the GPS III Non-Flight Satellite Testbed (GNST) and all ten Block III satellites. The first satellite in the series was launched in December 2018. The tenth and final GPS Block III launch is projected in 2023. History The United States' Global Positioning System (GPS) reached Full Operational Capability on 17 July 1995, completing its original design goals. Advances in technology and new demands on the existing system led to the effort to modernize the GPS system. In 2000, the U.S. Congress authorized the effort, referred to as GPS III. The project involves new ground stations and new satellites, with additional navigation signals for both civilian and military users, and aims to improve the accuracy and availability for all users.

Rocket-assisted Projectile
A rocket-assisted projectile (RAP) is a cannon, howitzer, Mortar (weapon), mortar, or recoilless rifle round incorporating a rocket motor for independent propulsion. This gives the projectile greater speed and range than a non-assisted Ballistics, ballistic shell, which is propelled only by the gun's exploding charge. Some forms of rocket-assisted projectiles can be outfitted with a laser-guide for greater accuracy. The German Sturmtiger (1944) used a 380 mm Rocket Propelled Round as its main projectile. These rounds were high explosive shells or shaped charges with a maximum range of 6,000 m. The gun first accelerated the projectile to 45 m/s (150 ft/s), the 40 kg (88 lb) rocket charge then boosted this to about 250 m/s (820 ft/s). Also the German Krupp K5 railway gun of World War 2 used rocket assisted projectiles in the later stages of the war, although it also used conventional artillery projectiles. The North Korean Koksan (artillery), M-1978 / M1989 (KOKSAN) 170mm self ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Low Rate Initial Production
Low rate initial production (LRIP) is a term commonly used in military weapon projects/programs to designate the phase of initial, small-quantity production. The prospective first buyer and operator (i.e., a country's defense authorities and the relevant military units) gets to thoroughly test the weapons system over some protracted amount of time—in order to gain a reasonable degree of confidence as to whether the system actually performs to the agreed-upon requirements before contracts for mass production are signed. At the same time, manufacturers can use the LRIP as a production test-phase where they develop the assembly line models that would eventually be used in mass production. Therefore, the LRIP is commonly the first step in transitioning from highly customized, hand-built prototypes to the final mass-produced end product. In practice, either the production capability or the weapons system itself can be unready during the LRIP phase. This can mean that systems produc ...

Fort Bliss
Fort Bliss is a United States Army post in New Mexico and Texas, with its headquarters in El Paso, Texas. Named in honor of William Wallace Smith Bliss, LTC William Bliss (1815–1853), a mathematics professor who was the son-in-law of President Zachary Taylor, Ft. Bliss has an area of about ; it is the largest installation in FORSCOM (United States Army Forces Command) and second-largest in the Army overall (the largest being the adjacent White Sands Missile Range). The portion of the post located in El Paso County, Texas, is a census-designated place with a population of 8,591 as of the time of the United States Census, 2010, 2010 census. Fort Bliss provides the largest contiguous tract () of restricted airspace in the Continental United States, used for missile and artillery training and testing, and at 992,000 acres boasts the largest maneuver area (ahead of the Fort Irwin National Training Center, National Training Center, which has 642,000 acres).

PzH2000
The Panzerhaubitze 2000 ("tank howitzer 2000"), () abbreviated PzH 2000, is a German 155 mm self-propelled howitzer developed by Krauss-Maffei Wegmann (KMW) and Rheinmetall in the 1980s and 1990s for the German Army. It is capable of a very high rate of fire; in burst mode it can fire three rounds in nine seconds, ten rounds in 56 seconds, and can—depending on barrel heating—fire between 10 and 13 rounds per minute continuously. The PzH 2000 has automatic support for up to five rounds of Multiple Round Simultaneous Impact (MRSI). Replenishment of shells is automated. Two operators can load 60 shells and propelling charges in less than 12 minutes. The PzH 2000 equips the armies of Germany, Italy, Ukraine, Netherlands, Greece, Lithuania, Hungary, Qatar and Croatia, mostly replacing older systems such as the M109 howitzer. In November 2019, a PzH 2000 L52 gun fired a shell a distance of 67 km. Development In 1986, Italy, the United Kingdom and Germany agreed to terminat ...
