Last December they successfully demonstrated its capability to launch a small payload into orbit, meaning that may soon be able to target regions in the U.S. and other distant locations.
Even ALCMs employing stealth technology are constrained by their lack of flexible, in-flight retargeting capability, their smaller ordnance payload, and the absence of a means of recalling them once they are launched.
Importantly, these intercepts took place during the boost-phase - a capability that means the missile and its deadly payload could be destroyed over the territory of a would-be attacker.
