though the chinese stillonsiderable way to go in trimming the weight and dimensions of their device, the progress demonstrated to date and the high priority being given to thermonuclear development indicate that the chinese probably will be able to develop an icbm warhead in the megaton range by in, we estimated that the chinese couldew icbms operational by theb. in the interim the chinese could have some multi-megaton thermonuclear bombs deliverable by medium bomber.
the broader implications of china's thermonuclear program will be discussed in, "communist china's strategic weaponshich is scheduled for publication in july.Original document.
