Yes, they do. The lowest cost per kg to orbit launch vehicles are not primarily solid.

  But if they can get missile cost to $1-2m, which I believe is very realistic, would there still be any big economic benefit from recovery when the launch will still cost few megabucks?

    For one its unlike to scale - especially if you are using similar stages as the military, once you reach a certain maximum payload, making a bigger rocket will be much more expensive as you would no longer share the development and production costs of the new stages with the military.

      And guided missiles and ICBMs are expensive. In fact, the cheapest large missiles are usually liquid.

    But no one has in spite of there being a super strong incentive to do so. Reuse is taking over the launch market. And for good reason: expendable aerostructures cost basically the same to build as reusable ones, certainly within a factor of 2 or whatever. A cruise missile and a similar dry mass general aviation aircraft cost about the same. For all the talk about (& investment in) low cost expendables, nobody has made it cheaper. Besides, reusable liquid rockets are easier on the payload (less vibration, etc).
