Despite the concerns about sharing the ALR-69 radar warning receiver with Pakistan for fear of it falling into Chinese hands, CIA officials argue that failure to meet Pakistani demands would lead to a “serious blow to U.S. worldwide nonproliferation efforts.”

With delivery of U.S. F-16 fighter-bombers imminent, Pakistan threatens to refuse delivery unless the U.S. agrees to include the ALR-69 radar warning receiver for the aircraft. CIA analysts have concerns that including this sensitive radar technology in the delivery of the F-16s would enable China, a close military ally of Pakistan, to obtain and study the device.

A planned update of the Special National Intelligence Estimate 31-32/81 concluded that Pakistan’s nuclear program was continuing and new evidence suggested a “significant” Chinese role in the design of the weapons. Despite this new evidence, CIA estimates suggest that the required amount of fissile material for weapons production would not be available as early as had been predicted, and that a Pakistani nuclear test was not imminent.
