Semi OT - Cruise Missiles

[kato13]

Was thinking about the advantages/disadvantages of cruise missiles versus SLBMs. Does anyone here know if cruise missiles can reach an optimum burst altitude for a medium sized (150kt) nuclear warhead. I don't think that most long range cruise missiles would have a rapid climb rate. Also during such a climb interception would probably be much easier. Therefore my opinion is that most cruise missile nuclear attacks would end up being nearly ground bursts.

Anyone have any information/opinions on this.
