The 6.8 mm round is a cartridge designed to provide improved lethality for military applications. It was developed as part of the U.S. Army's Next Generation Squad Weapons (NGSW) program, which aims to replace the current 5.56 mm and 7.62 mm ammunition used by the military. The 6.8 mm round is intended to offer a significant increase in kinetic energy and penetration, making it more effective against armored targets and at longer ranges.
Background and Development
The development of the 6.8 mm round began in response to the need for a more effective cartridge that could meet the evolving requirements of modern warfare. The 5.56 mm round, which has been in use since the 1960s, was found to be inadequate in certain situations, such as against armored targets or at longer ranges. The 7.62 mm round, while more effective, was also seen as having limitations, including a shorter effective range and less accuracy. The 6.8 mm round was designed to address these limitations and provide a more versatile and effective cartridge for military use.
Design and Characteristics
The 6.8 mm round is a centerfire cartridge, meaning that it is ignited by a primer located in the center of the cartridge case. It has a bottleneck design, with a larger diameter case and a smaller diameter bullet. The cartridge case is made of brass and is designed to be durable and resistant to corrosion. The bullet itself is made of a tungsten alloy and is designed to provide maximum penetration and kinetic energy.
| Characteristic | Value |
|---|---|
| Caliber | 6.8 mm |
| Case length | 51 mm |
| Overall length | 71 mm |
| Bullet weight | 135 grains |
| Muzzle velocity | 2,700 ft/s |
| Muzzle energy | 2,400 ft-lbs |
Performance and Capabilities
The 6.8 mm round has been designed to provide improved lethality and performance compared to existing cartridges. It has a flatter trajectory and a longer effective range, making it more effective at longer distances. The round is also designed to provide improved penetration and expanded wound channels, making it more effective against armored targets and in situations where maximum kinetic energy is required.
Comparison to Existing Cartridges
The 6.8 mm round has been compared to existing cartridges, including the 5.56 mm and 7.62 mm rounds. The results show that the 6.8 mm round provides a significant increase in kinetic energy and penetration, making it more effective against armored targets and at longer ranges. The round is also designed to provide improved accuracy and a reduced recoil, making it easier to handle and more effective in a variety of situations.
- Improved lethality and performance compared to existing cartridges
