Тема: Lightweight Small Arms Technologies program
Когда-то это уже упоминали, но не нашел в какой теме - решил создать новую, тем более вроде как жив курилка, и даже продвигается вперед и с песней:
To try out the new lightweight ammunition and machine gun, a small group of Soldiers and members of the Army and Navy Senior Executive Service attended a live-fire demonstration in June at the Marine Corps Base in Quantico, Va.
Sgt. Jason Reed of the Soldier System Center in Natick, Mass., demonstrated firing both the LSAT LMG and the SAW from various positions -- from prone to kneeling to standing while in full combat protective equipment.
“The difference between the two weapons is night and day,” Reed said.
“The main thing I would take away from this is the weight issue, especially when firing in the standing position,” Reed said. “Bringing up the SAW, especially if you have it up for a long duration of time, it starts to get the best of you and you have less accuracy on target.”
Despite the significantly reduced weight of the LSAT LMG and its ammo, there is no degradation in accuracy or lethality.
“The cased telescoped ammo still provides the same muzzle velocity, range and accuracy as the brass-cased ammo,” Phillips said. “We’re not sacrificing lethality for weight. The plastic case does the same job.”
In addition to significant weight savings, the LSAT is designed to provide other advantages over the current SAW. With a rotating chamber design, the cased telescoped light machine gun improves reliability.
“We’ve avoided the common problem of failure to feed and failure to eject,” Phillips said. “In the current SAW system, that’s one of the places where you primarily have failures and malfunctions.”
The chamber is unique in that the cartridge goes straight through from feed to eject.
“With a regular SAW, or M249, the chamber and barrel is one piece,” Phillips explained. “But in this new light machine gun, the chamber rotates back and forth. The system works in a cyclical pattern, so there’s no interference.”
Additionally, the rotating-chamber design provides better heat management. Combined with the insulating properties of the plastic ammo cases the LSAT LMG has potential to decrease the possibility of a cook-off or eliminate them altogether.
Another significant feature is the long-stroke, soft-recoil design, which provides a noticeable reduction in felt recoil over the current SAW. This significantly increases control, thus providing the shooter the ability to put more rounds on target and making the weapon much easier to fire from the standing position as a result of decreased muzzle rise.
Moreover, the LSAT LMG has one other unique feature that the current SAW lacks: the ability to switch to a semi-automatic mode. This feature increases the flexibility of the weapon, allows for the precise engagement of point targets, and helps to conserve ammunition in situations where full-automatic fire may not be necessary or desired.
In September, the weapon and ammunition will undergo a Military Utility Assessment that is intended to demonstrate the advantages that the LSAT LMG provides for the warfighter, as well as possibly influence the user community to develop a Capability Development Document, or CDD.
A CDD is required before the system can transition to a program of record and enter the engineering and manufacturing development phase.
