What level do you unlock the tactical nuke in cod mw2?

Answer 1

You unlock the Tactical Nuke at level 51 or 52.

You can unlock the Nuke at whatever level that you like, as long as in that level, you are aloud to unlock it. Like, at level.... 15, lets say, you can unlock any of the killstreak rewards, even the Nuke! hope this helps!
