since it will take time for them to reach the Rocket launching stage of the game. and be able to do the scavenging adventure of locating the site. and probably a HUGE　Radar station just to show which direction the Silo site is located (no distance) and another To actually SHOW in the map where the Silo is actually located.

The point is to find the silo. The silo is always to the right and the map is not that high. If the player wants, they can add radar mods in order to get longer range to show the silo is they want.
