[Spaceships] Stealth Missiles?

[Cernig]

Does anyone want to hazard an educated guess at the SMs of standard caliber missiles?

I ask because I've a Space campaign in set-up where the TL10^ stuff I'm envisioning means a standard set of engagement ranges and turn length but highly propbale detection even of warships at ranges beyong extreme (most fall in the 0.1 AU range for "probable" detection, which will take about 1.5 hours to travel) and of "warp scars" left by ships emerging from warp-space detectable at ranges of 0.1 to 1AU depending on SM.

So, I want to steal an idea from Honor Harrington of having brillant missiles launched wayyyyy out, then coast until their final attack boost from normal engagement ranges...and stealth them to boot to make them even harder to detect.

Who needs a stealth "merchant raider" when you can use these babies? And in warship combat you time your salvo to arrive on target to disrupt the well-warned defenders just as your warships arrive in combat range.

But I need good info on missile SMs to scale the costs.
