This is supposed to be a manouvering reentry vehicle. I guess the downside is reduced accuracy and payload. Current missile defense trackers and interceptors are predicated on a ballistic trajectory, i.e., a missile in free fall after deployment. A little manouver can greatly complicate the problems for the defenders. Of course, boost phase interception (with a space based defense) is probably the best solution. Too bad we aren’t gonna do it.
I thought all but the most crude, 1950’s era ballistic missle technology allowed for warhead separation after the boost phase? Only cheap-@ss SCUDS come down intact (unless they breakup due to aerodynamic stresses)?
Russia has tested a technology that everybody knew was possible for countering ABM’s. Let’s see if they can afford to actually buy it.
