Ellamy proved that there will be times when you bring back Stormshadow - more so in this brave new world.
I agree with downsizer - we need to worry about getting it on the jet before we worry about getting it off!
Also, it is hard to think of a scenario where our mighty "carrier strike" force of 12 JSF (how many of those will be doing fleet defence?) would be fighting that type of war without land based support. I would suggest getting more capability out of TLAM would be a better use of resources.
