At the "Innovation Days of the Russian Ministry of Defense" the Makeyev Design Bureau (formally known as the Academician V.P.Makeyev State Rocket Centre, GRTs) presented one of its recent projects - a maneuvering re-entry vehicle (MARV).

The leaflet distributed by the GRTs (at the open part of the event), said that it's a "high-speed maneuvering [combat] re-entry vehicle for land-based and sea-based strategic missile systems." As one would expect, it's advertised as a way to defeat missile defenses by preforming "unpredictable maneuvers with high transverse accelerations." It apparently relies on aerodynamics to do those, as it can only deal with the "low-altitude" (i.e. terminal) defense. So, it's not the Project 4202 or whatever the hypersonic vehicle Russia may be working on.

This is nothing particularly new, since MARV technology has been around for decades and the last time it was clear that the cost (in terms of payload) is not worth the price of penetrating defenses, especially when those defenses are non-existent. Nothing has changed since then - the only terminal (strategic) missile defense is deployed around Moscow and dealing with that would hardly require a sophisticated MARV. Someone in the GRTs marketing department didn't quite do their homework.
