The AN/PAS-13 Thermal Weapon Sight (TWS) provides Soldiers with individual and crew served weapons the capability to see deep into the battlefield. It increases surveillance and target acquisition range, and penetrates obscurants either day or night. The TWS systems use uncooled, forward-looking infrared technology. It provides a standard video output for training, image transfer or remote viewing. Thermal Weapon Sights are lightweight systems that Soldiers can mount on a weapon rail and operate to the maximum effective range of the weapon.
PM SMS included 17 micron (17um) technology in FY12 awards. This resulted in size, weight and power improvements over present configurations.
The TWS family comprises three variants, each of which is a silent, lightweight, compact, durable and battery-powered thermal sight. They are:
- AN/PAS-13(V)1 Light Weapon Thermal Sight (LWTS) for the M16 and M4 series rifles and carbines, as well as the M136 Light Anti-Armor Weapon.
- AN/PAS-13(V)2 Medium Weapon Thermal Sight (MWTS) for the M249 Squad Automatic Weapon and M240B series medium machine guns.
- AN/PAS-13(V)3 Heavy Weapon Thermal Sight (HWTS) for the squad leader’s weapon, M16 and M4 series rifles and carbines, M24 and M107 sniper rifles, and M2 HB and MK19 machine guns.
