What are you saying, let the missile float to the surface and then start the engine to launch?
Or actually start engine underwater, using fuel to push through water (more viscous than air, therefore more resistance, needing more thrust) and then continuing into atmosphere (as sub-launched ICBMs do)?
The first case has no fuel-saving advantage over a normal launch from sea-level, the second would require more propellant for the initial launch through the water to get to the surface.....
For a weird bit of escapism, try Vurt and the associated books in it's series..

Try the digital optical output at the back of the PS2.. I find it very handy for copying CDs onto Minidisk.
