The actual C-5 is similar to the AAM-4(at least in this case). And the C-7 appears to have increased range with its loft. If the relative position is correct, it can be said to be historical. If C-5 uses magic, you’ll need to rethink it.
Is there any information on the increase in range due to the navigation of the C-5? If that is due to a change in the motor, the stand-off range will be affected by the motor. The possibilities for 4B different propellants, motors are even greater.
Except nothing where japan talks about developing new rocket motors mentions the AAM-4 getting one.
The same applies to information that clearly states that there have been no changes or improvements. At the very least, the standoff range increases, but there is no information that it is based solely on navigation.
What do you think about the relationship between effective range and maximum range? Would the motor change you proposed (the mains are stronger and shorter, and the sustainers are stronger and longer) increase the energy that the missile has?
