This is Volume II of National Intelligence Estimate 11-14-79, Warsaw Pact Forces Opposite NATO, issued by the Director of Central Intelligence and dated January 1979. The National Foreign Intelligence Board concurred with it. It was the first comprehensive estimate of Pact forces facing NATO since 1971. It covers Pact doctrine, the ground, air, naval, nuclear and chemical forces, command and control, and campaign plans for war in Europe. It judges that Central Europe would be the decisive arena, and it lists Pact weaknesses in pilot training and antisubmarine warfare. The document contains no UFO material.

The holders of this view are the Director,National Security Agency, and the Directorof Naval Intelligence, Department of the Navy. The longer range and radius values in the assessment of the Backfire by the Central Intelligence Agency are based on an assumed aerodynamic design which is optimized for subsonic performance, while the shorter range and radius values are based on an assumed compromised design. CIA has considered both designs because they represent reasonable upper and lower bounds of the Backfire's subsonic cruise efficiency. dThe uncertainties in these estimates of the Backfire's performance are as follows: CIA range ±300 nm, radius ±160nm; DIA/Army/Air Force range +162 nm, -486 nm, radius +87 nm, -261 nm. The radius/rangevalues of the DIA/Army/Air Force assessment, with a 4,500-kg (10,000-lb) payload, comparable to that used by the CIA assessment, are 2,950/5,750 nrn unrefueled. rThese radius/range values are for a high-altitude, optimum-cruise profile except for a 200-mn subsonic dash at sea level into the target area. The radius value also includes a 200-nm subsonic dash for egress (400 rn total). s The radius value includes 200 nm for ingress and 200 nm for egress at supersonic speed (400 nm total); the range value includes 200 run for ingress only. 579031 an cu 11-57 Top '
