In order to achieve escape velocity, how fast will the spacecraft need to be going to counteract the air friction it will encounter once it leaves the launch tube? I imagine it will have to be moving at a much higher rate of speed then escape velocity in order to push through all that air.
Then your greatest speeds will be through the densest part of the atmosphere. I imagine this will put a lot of heating onto the vehicle. Probably more than the shuttle at landing. Has this problem been overcome?

At no time time during the Iraq - Iran war did the sale of military weapons between USSR and Iraq stop or slow down. http://www.sipri.org/contents/armstrad/TIV_imp_IRQ _70-04.pdf
