TheNCSIST Chien Hsiang (Chinese:劍翔無人機;Pe̍h-ōe-jī:Kiàm-siông;lit. 'Rising Sword') is a Taiwanese anti-radiationloitering munition developed and produced by theNational Chung-Shan Institute of Science and Technology.
The Chien Hsiang is 1.2 meters long and has a wingspan of 2 meters.[2] It has adelta wing and apusher propeller.[3] The Chien Hsiang has a reported loiter time of 100 hours and a top speed of 185 km/h.[4] They are primarily intended to fill the anti-radiation weapon role targeting enemy radars, transmitters, and associated systems.[3]
While the Chien Hsiang is comparable to the IsraeliIAI Harpy, NCSIST has said that any resemblance is coincidental and that the platform is entirely indigenous.[5]
A variant with a sensor ball mounted under its nose has been displayed.[3]
The Chien Hsiang was first exhibited in 2017 at theTaipei Aerospace & Defense Technology Exhibition.[6] In 2019, the Taiwan Air Force’s Air Defense and Missile Command announced a five year, NT$80b (US$2.54b) project to build up a full force of anti-radiation UAVs.[7]
In 2022, it was reported that Chien Hsiang production was ahead of schedule and initial procurement was expected to be completed by 2024 or 2025.[8]
The main Chien Hsiang launch platform is a trailer mounting twelve box launchers.[2] It can also be launched from fixed positions and naval vessels.[9]
Designed to confuse air defenses systems in conjunction with strike Chien Hsiangs.[10]
Two Chien Hsiang derivatives with larger warheads were displayed in 2023.[10]
