This is a condensation of an article that appeared in Commercial Space Report and in Claustrophobia: The subject is a launch vehicle called Seadragon (and the 20-year development program Truax plans to culminate in it). The basic idea is to make it super huge, 40 million pounds, so that the efficiencies of scale allow it to be built with ordinary (shipbuilding) construction techniques and materials. The design is unconventional. Liquid fuel, low pressure, single engine rockets. First stage LOX and RP-1 (what's RP-1?) operating at 300 psi (!), second stage LOX/LH 60 psi (!!). The second stage has a large umbrella-like extension for the nozzle which is wrapped around the first stage before separation. Sea-launched. Both stages sea-recovered. Payload to LEO of 1.5 million pounds. They are shooting for $20/lb. Sounds intriguing. --JoSH -------
