When the air war started, the entire North Vietnamese air defence system contained twenty-two early warning radars, four fire-control radars, and 700 anti-aircraft guns. By 1967, North Vietnam was firing 25,000 tons of anti-aircraft ammunition a month. When President Johnson halted Rolling Thunder on 1 November 1968, this had grown to 400 radar sites, 8,050 anti-aircraft guns, 150 fighters (including reserves based in China), and 40
SA-2 ''Guideline'' missile sites. The bombing halt allowed the defenders to rationalize and improve their system, which eventually included 200 SA-2 sites around the country and along the
Ho Chi Minh trail.
