Overview

The Chien Hsiang is 1.2 meters long and has a wingspan of 2 meters.[2] It has a delta wing and a pusher 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 Israeli IAI 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]

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]
