Rockets follow some paths

anyone have any idea how to implement this:

a central tower will launch two parallel missile, which will reach a point X in the 3D environment, I wanted them to leave this launcher but did not follow a straight path to the point X, but they'll perform a curved path and cross in the air, leaving a smoke trail, reaching the point X, both at the same time.

I have some crazy ideas for the script, but I'd like some help, if possible.
