I've been waiting for the Chinese to unveil a missile like this one. It didn't make sense, to me, that China would neglect exploiting the advantages that the P-700, P-800, Brahmos offers. I'm a long-time fan of the P-700 3M-45 Granat/SSN -19 Shipwreck missile and its derivatives. I think the best range for a missile of this type would be ~450 km/280 mi. For subs, that's a safe launch distance from CBGs and, for aircraft, it's outside the standard CAP radius. Of course, with the ~ 30' length and ~4500 kg weight this range would require, it would take one helluva aircraft to carry it.
