In LOUD we've had the SMD able to shoot down satellites for years - with a separate weapon that doesn't drain the SMD. It contained the Novax, at least in terms of it just sitting overhead without any challenge. However, as I mentioned earlier on, this just shifted the meta for it, to one of area denial, and the same fundamental gameplay issue continues to exist. The Novax can effectively seal a player into his shielded base, and even trying to escape using mobile shields is not effective in breaking that blockade.
I imagine, that as long as the Novax continues to exist, it should be considered a need to have some kind of anti-sat units and/or weapon, that can effectively counter it. The Black Ops SMD solution is, as mentioned above, somewhat effective, but not entirely so.
