One additional argument in favor of surfacing the OXCART was the realization that the aircraft could not be used to fly undetected over the Soviet Union. By 1962 the United States had become aware of the effectiveness of a new Soviet radar system, codenamed TALL KING. The introduction of this computer-controlled radar undercut one of the basic premises of the OXCART program, the assumption that radar operators would not be able to track high-flying supersonic targets visually because of their small, nonpersistent radar returns. By coupling a computer to a radar, the Soviets could now weight the individual radar returns and identify those produced by high-flying, very fast objects. $ ^{41} $
By February 1964 DCI McCone had become convinced that surfacing was necessary. Soviet development of the TALL KING radar system had eliminated his hope that OXCART would eventually be able to carry out its original intended purpose-overflights of the USSR. The final decision on the issue of surfacing the OXCART came at a National Security Council meeting on 29 February 1964, at which all of the participants supported the decision to surface. That same day President Johnson held a news conference at which he announced the successful development of an "advanced experimental jet aircraft, the A-11, which has been tested in sustained flight at more than 2,000 miles per hour and at altitudes in excess of 70,000 feet." $ ^{42} $
President Johnson had spoken of the A-11 rather than the Agency's A-12, and the aircraft that was actually revealed to the public was the Air Force's YF-12A interceptor, a project that had already been canceled. $ ^{43} $ Following the President's announcement, two of Not linked to a story yet.
