International Weapon Sights

Compact Thermal Sights for Decisive Maneuvers

The Individual Weapon Sights (IWS) are an advanced set of clip-on infrared weapon sights, based on Leonardo DRS’ field-proven 17 µm thermal sensor technology. The IWS combines rugged, lightweight, modular construction with superior thermal imaging technology to give today’s Warfighter the capability to maintain uncompromising performance in day or night and in smoke or fog, significantly increasing survivability and decisive operations on the battlefield.

At the core of the IWS lies decades of experience in the uncooled infrared (IR) weapon systems field.

  • The sight employs a proprietary high sensitivity vanadium oxide (VOx) focal plane array (FPA).
  • The IR FPA requires no visible light to operate and will not shut down or create glare when exposed to direct light.
  • The IWS operates silently and emits minimal heat and radio frequency (RF)
    energy, ideal for undetected reconnaissance.

Available in two configurations; Standard (IWS) or Long-Range (IWS-LR) for advanced missions, the IWS is constructed to function as a night vision system when mounted in front of a day vision optic (DVO) sight on a wide variety of qualified weapons. It is uniquely designed as a cost-effective, high-performance, and portable solution.

The clip-on functionality eliminates the need for re-bore sighting as the DVO accuracy is undisturbed. Also, the IWS design allows the sights to be used as a stand-alone TWS without a DVO and as a hand-held thermal imager.
