The M982 Excalibur (previously XM982) is a 155 mm extended-range guided artillery shell developed in a collaborative effort between the U.S. Army Research Laboratory (ARL) and the United States Army Armament Research, Development and Engineering Center (ARDEC). [5]
M712 Copperhead approaches an old M47 Patton tank used as a target M712 detonating. The M712 Copperhead is a 155 mm caliber cannon-launched guided projectile.It is a fin-stabilized, terminally laser guided, explosive shell intended to engage hard point targets such as tanks, self-propelled howitzers or other high-value targets.
A XM1113 extended range artillery round, shown here at a range demonstration, uses a rocket-assist motor. The M1299 was armed with a new 155 mm L/58 caliber long, 9.1 m gun tube, XM907 gun, designed by Benét Laboratories to fire the XM1113 rocket-assisted round. This would give a range of over 70 km (43 mi) – much greater than the 38 km (24 ...
The path of this projectile launched from a height y 0 has a range d. In physics, a projectile launched with specific initial conditions will have a range. It may be more predictable assuming a flat Earth with a uniform gravity field, and no air resistance. The horizontal ranges of a projectile are equal for two complementary angles of ...
XM1113 extended range artillery round, shown here at a range demonstration, uses a rocket-assist motor. The U.S. Army is developing the XM1113 rocket-assisted projectile to replace the M549A1 shell. The XM1113 increases range from 30 to 40 km (19 to 25 mi) from a 39-caliber barrel using a large high-performance rocket motor delivering nearly ...
Figure 5: Illustration of a Cam-Based Function During World War II, cams were precisely machined to represent the firing tables for long range artillery. Firing artillery at targets beyond visual range historically has required computations based on firing tables. [22] The impact point of a projectile is a function of many variables: [23] Air ...
For US artillery ammunition, these projectiles are called Dual-Purpose Improved Conventional Munition (DPICM), a 155 mm M864 DPICM projectile for example contains a total of 72 shaped-charge fragmentation bomblets. The use of multiple bomblets over a single HE projectile allows for a denser and less wasteful fragmentation field to be produced.
Directing the fire of a long-range weapon to deliver a projectile to a specific location requires many calculations. The projectile point of impact is a function of many variables, including: gun azimuth, gun elevation, wind speed and direction, air resistance, gravity, latitude, gun/sight parallax, barrel wear, powder load, and projectile type.
