But, at that range, even though I can select a radar track, I cannot launch the weapon at an incoming missle until around 27,000.

Further more, for air contact, I can track and engage an air contact at 64,000. To go one step further, surface contacts cannot be engaged by the sm-2 until at a range of 16,000.

These figures do not add up, why such a big difference in engaging air contacts as to incoming missiles, then ontop of that, surface vessels.

Launching at a target depends on having a true FCR flag; the an/sp-49 is pretty much irrelevant.

The reasons for the exact figures you're getting will depend on if you're using stock or lwami (I'm guessing with an engagement range for surface contacts of 16,000m you're using a lwami database). I don't know all the tricks, but lwami is set up to take earth curvature into consideration, while stock DW allows "over the horizon" engagement of surface contacts with the SM-2. At a minimum, this is because the Earth Curvature flag is set true for the FCRs in lwami, but there may also be other factors. I don't know for sure, but the difference in engagement ranges between missiles and air contacts (assuming they are at the same altitude) may be differences in radar cross section, which may determine how far inside the detection envelope a contact must get before its detected. Again, just a guess. But the Earth Curvature flag is definitely a factor if you are using the lwami database.
