North Vietnamese Air Capabilities Increasing
North Vietnamese nowmalladvanced supersonic jet fighters, possiblysome type of air-to-air missile, and theyadvantage of operating from bases much nearer
the area of probable conflict than do US aircraft. It is nevertheless unlikely that they can seriously challenge US air superiority over North Vietnam. The US air forces continue to have numerical superiority, better weapons systems and radar, and better trained pilots. Although North Vietnamese pilots haveertain degree of increased aggressiveness during the past two weeks, they will probably continue toonsiderable degree of caution in engaging US strike aircraft.

Problems in US Air Operations
patrols over North Vietnam areby the distances involved and the lack oftactical air control system. out of bases in Thailand are refueled prior
to entry into North Vietnam, giving theminutes flying time over North Vietnam. Fighters from Da Nang and Seventh Fleet aircraft carriers aro not refueled and haveinutes of flying time over North Vietnam. This time is reduced when air engagements increase the fuel consumption. The DRV MIGs, on the other hand, have approximately one and one-half hours flying time over the DRV.

US fighters operating in the northwest DRV or areas north of Hanoi are in the fringe areas of radar control and must rely on their own airborne radar and airborne COMINT platforms for warning of HIGs aloft.

Despite the difficulties, there is no doubt that the US will continue to control the air over North Vietnam for some timo to come. In addition to the overwhelming numbers of aircraft that the US can put into the air, those fighters are equipped with superior air-to-air missiles and airborne radar than that which is estimated to be in North Vietnamese hands. Equally important, the average experience and training of US pilots is far superior to that of the North Vietnamese.
