IDEALIST/TACKLE China Mainland
Offshore Mission Constraint
1. You will recall that the following question was raised during
the 20 December 1969 303 Committee meeting: "How much, degradation
would occur to the IDEALIST/TACKLE mission product if the current
303 Committee route constraint for these missions was changed from
20 NM. offshore from the China mainland to 20 NM from the China
mainland offshore islands? "
2. My staff has applied the IDEALIST/ TACKLE mission planning
parameters to this question and has determined that the mission photo-
graphy would be significantly degraded in that a 37 to 52 per cent target
coverage reduction can be anticipated due to the increased camera to
target distances. In addition, the mission product will also be degraded
by an unpredictable amount due to the increased oblique angle of the
photography and the resultant lack of penetration of the normally
encountered haze conditions along the China coast. The movement of
the flight path further offshore would in many instances place the aircraft
40 - 60 NM from the mainland
