Hpasp, do you believe the maximum engagement ranges listed above, 380km against aircraft and 60km against ballistic missiles is accurate?

In your MIM-104 Patriot thread your missile comparison list says, "48N6E2 missile 200km range", "48N6DM missile 250km range". I have some ideas as to how the 9M96E2 can have double the range of the 9m96 but do you have any idea as to how the Russians got another 120 to 180 kilometers of range out of the 48N6E2 and 48N6E3 missiles?
