What is the flight radius of IPM's?

they are useless do not waste your money

Formula in infos: http://xcraft.ru/infos/?gid=503

There is no info on radius ...... anyway I guess they are useless ..... cant even target the galaxy beside me

The Impulse Drive level is factored into the flight radius.

Each level of the development increases the radius of flight of the Interplanetary missiles.

Why they use Impulse and not Rocket I have no clue, but that is how it is set up.

I have level 10 Impulse Drive and can hit planets about 9k+ away. So it might be set to 1k each level after level 1? just a theory since it increased another 1k after I completed level 10...
