Are there any multistaged air to air weapons with hypersonic speeds in planning?
The R-37 "Arrow" and K-172 "Anti-Awacs" (now sometimes called the K-100) are apparently still in development. Both have jettisonable boosters (at least as options), and fairly high speeds.... Mach 3.8 for the KS-172 and Mach 6 for the R-37 according to Wikipedia.
If they're ever going to equip the Flanker series or the Pak-FA is anyone's guess. If more MiG-31BMs are built it could be a carrier for the R-37 as well. Russia is having enough trouble getting out the more mundane weapons. However, I read that a new R-77 version and short range missile (R-73 version?) will be shown at MAKS 2009, August 18-23.
