Israel Aerospace Industries revealed several new loitering munitions at the 2016 Singapore Airshow, including a new variant of the Harpy.

The Harpy New Generation, or Harpy NG, is an updated version of its predecessor designed to counter modern air defense radar threats. The new variant is able to cover lower frequencies, and features a more advanced airframe enhancing its flight capabilities, loiter time, range and altitude.

In addition to the Harpy NG, IAI also introduced the Green Dragon. The Green Dragon is a tactical, all-electric loitering munition designed to provide both firepower and situational awareness to small ground and special operations units.

"IAI is introducing two new Loitering Munitions, intended to refresh, update and complement our already successful family of LMs," IAI Systems, Missiles & Space Group vice president Boaz Levi said in a statement. "The new tactical products serve to bolster the abilities of small tactical infantry units and Special Ops, with a special emphasis on solving operational problems in urban areas."

The Green Dragon is able to engage enemy targets while also collecting visual intelligence at a range of up to 24 miles. Twelve to 16 of the munitions, launched from sealed canisters, can be carried on a small vehicle at a time. The LM also features an "abort and go around" capability.

The Singapore Airshow is a biennial government and military product exhibition. The event features strategic conferences and demonstrations of commercial and military aerospace products.
