But booth staff interviews showed what appeared to be just a random aircraft they found, and there was even a Mirage 2000 model carrying HD-1A on the booth.
Fair enough, this by itself doesn't qualify as confirmation. Technically, the weight shouldn't be an issue for the JF-17, a couple of HD-1As are within payload parameters.
It's a powerful capability though. You've got the ability to use HD-1As to attack point-defense systems and follow-up with GB6s with cluster payloads. That basically means that half a squadron of JF-17s can take out an entire Armored Division, or an Air Field.
