I have something that may or may not be a database issue; maybe it's just the way the game works, or maybe it's something the player needs to worry about.
This involves CWDB399, the RIM-24C Tartar as mounted on ship #2075 DDG19 Tattnall [Charles F. Adams]. The database viewer of the ship shows the missile as having a range of 18nm. This is also shown on the map as the surface weapon ring for the ship has a radius of 18nm. The database viewer of the missile says it has a max speed of 1475knts and a flight time of 44 seconds,
When a target is selected for the ship using F1, the Tartar is launched pretty much as expected when the target gets withing the 18nm surface weapon ring. However, when the ship launches the Tartar against a surface target, as soon as the missile is launched, the surface weapon ring shrinks to about a radius of 11.5nm, and this turns out to be about where the launched missile runs out of fuel. The missiles will hit a surface target at 12nm, I guess it's good for about a half nautical mile of gliding.
After some more checking I find that the missile does have a flight time of around 44 seconds, but when fired at a surface target it never quite reaches that 1475kt speed. In fact it takes more than half the flight time for it to reach even 1000kt.
What appears to be happening is that the game calculates the surface weapon ring of 18nm based on the missile speed of 1475kt and a flight time of 44 seconds. However, once the missile is launched, it appears that the surface weapon ring is re-calculated based on the predicted missile range based upon it's actual average speed over the 44 second flight time. Or maybe I'm looney[&:].
As a final test, I modified my test scenario to make the DDG19 Tattnall be the AI controlled ship and gave it a mission to kill my player controlled ship. As I moved my ship to just under 18nm from the Tattnall, that ship started firing Tartars at me (I have God's Eye view enabled). And as expected, they each ran out of fuel as they moved to about 12nm to 13nm away from the Tattnall. The Tattnall kept firing Tartars at me, and each one dropped into the ocean as it's fuel ran out.
So, to summarize, there's something wrong here[:D]. I'm not sure what the fix is. Good luck!
UPDATE: I may have been mislead on the changing surface weapon ring, saying it went down to 11nm or so because of the recalculated missile range. It would instead appear that the 11nm surface weapon circle was due to the 127mm gun of the Tattnall now being the longest ranged weapon while the missile launcher reloaded.
So we still have the problem that the AI wants to fire the missile at 18nm, but the missile won't fly further than 12nm or so.
