Yes, ATASD can be produced at our partner's US facilities and supplied as a CKD or SKD kit, declared as "Made in USA". The only one and the major problem is to reach decision making authorities of Coast Guard for sending them a proposal.
ATASD website is www.airatv.com
In Canada, I'm manufacturing 9 and 12 persons Search & Rescue amphibious transformers ATASD that are a combination of hovercrafts, airboats and inflatable rafts technologies
The craft you mentioned as "This is a Chinese hovercraft called "Heihe"" is actually Russian made Irbis-32 with building #002 that was sold to Chinese operator by Russian manufacturer Neptune.
