Externally, Mirage Hunter looks identical to Sea Shadow (IX-529), albeit on a much scaled-down size, and both ships adopt the same small-waterplane-area twin hull design.[1] [2] [3] Mirage Hunter is built by a shipyard in Wuhan, where the 701st Institute of China Shipbuilding Industry Corporation (CSIC) headquartered. 701st Institute is the primary Chinese research establishment conducting research on stealth features for ships and boats, and it is therefore postulated that Mirage Hunter AGTR is used by Chinese to research on the hull form of naval stealth technology and countermeasures.[1] [2] [3]
