Next Generation Delta 100 t

American orbital launch vehicle. Conceptual next generation Delta booster beyond Delta IV Heavy, equaling Saturn V of the 1960's in payload capability. The booster would use two parallel 7-m-diameter booster stages, a notional RS-XXX LOx/LH2 rocket motor, and a 7 m diameter upper stage and fairing. Payload fairings of 7 m diameter could be accommodated. Introduction would require new launch pads and booster assembly infrastructure, and a new factory to handle the larger-diameter tooling.

LEO Payload: 91,000 kg (200,000 lb) to a 407 km orbit at 28.50 degrees. Payload: 35,000 kg (77,000 lb) to a earth escape.
