How does the launch altitude alter the range of a missile?

[SKNath]

Let's say, a missile fired from ground level is limited in range by aerodynamic and drag factors upto 3 kms. So how would that range be altered if the missile is fired from an altitude of 5 kms above mean sea level? What are the factors we need to take into consideration to calculate its range in this case?

You need to be more specific about the parameters constituent of the proposed circumstance you describe. As it stands, the information you have given is subject to a varying number of assumptions in more than a few places. The main problem, being how you worded your first sentence.
