Little information has been officially and publicly revealed by Viettel or any parts of the Vietnam Ministry of National Defence; however, according to many pictures and pieces of information shared in the media, VCM-01 is likely developed and derived from the Russian Kh-35UE anti-ship missile, which is currently the backbone anti-ship missiles operated by the Vietnam People's Navy.
[6] No further information was announced or reported by the local authorities as well as Viettel, including the results of those activities and the existence of any other test fires besides those mentioned.
This is the engine used in South Korea's SSM-710K Haeseong anti-ship missile, as well as its tactical land-attack variant SSM-750K Sea Dragon.
[14][15] Many Vietnamese and international sources (including SIPRI) believe that "KCT-15" was a Vietnamese project to copy or assemble the Kh-35E/UE anti-ship missile as an effort to improve self-reliance on the supply and technological mastery of armaments for the Vietnam People's Navy as well as the entire People's Army of Vietnam.
[9] However, "KCT-15" was never a designation for any missile development project undertaken by Vietnam or Viettel, and in fact, the prefix "KCT" is used to designate a set of projects in a program to study and master the operation and maintenance of the Kh-35 missiles used by the Vietnam People's Navy.
