Personally, the biggest difference is that Hong Niao is a general multi-platform cruise missile, which can be fixed on the ground, launched by air fighters, launched by surface ships and underwater submarines. That is to say, Hong Niao has a small number of equipment and is not in service. At present, Sword 10 can only be launched on land vehicles, but it is mass-produced equipment, which is very mature and can cover the whole territory of hostile countries such as Japan, India and Vietnam. The derivative of Long Sword Donghai 10 should be a ship-borne model. The model of submarine-launched is unknown at present.
