Japan Plans 'New Generation' Launch Vehicle (Aviation Week & Space Technology)

In addition to a higher capacity version of the H-IIA, Japan's aeronautical establishment is intent on drawing from that exercise to develop an entirely new heavy-lift launch vehicle in the next decade.
As yet unnamed, this "new generation" launch vehicle (NGLV) is expected to emerge 10% lighter than the 285-metric-ton H-IIA and, at 55 meters (180 ft.), 2 meters longer. Like the H-IIA, it is to have two cryogenic stages with multiple mix capabilities for strap-on boosters. But the NGLV is to have 10-20% greater lift capacity than its predecessor.

これはいったい何のことなの？ やはりネタ元は NASA Watch。
