It'd take considerably longer than 50 days, even given the most favorable realistic circumstances, to get any kind of ground launcher ready. There's next to no ground-launched Tomahawk systems in existence, apart from a tiny handful of Typhons - I don't know why they bother, considering the Chinese have literally thousands of much more capable missiles pointed the other way, and very substantial air defenses.

There might be some naval tube launchers you could nigger-rig for ground launch, a bit like how the Argentines adapted some naval Exocet launchers for ground use in 1982 - picrel. What they did has ample precedent, by the way; in the days of wooden ships, it was very common to land guns off ships of the line (I think they needed new carriages, though) with their gun crews becoming artillerymen on land.

I'm not sure if any suitable horizontal launchers *exist.*
