A Grumman alternate Space Shuttle concept with a low cross range orbiter and a trio of 156-inch diameter solid propellant rockets for the first and second stages. The orbiter itself was stuffed with liquid hydrogen and liquid oxygen tanks; even so, the high density of the solid rockets meant that the vehicle as a whole was remarkably compact.

A Grumman alternate Space Shuttle concept with a low cross range orbiter and a series of pressue-fed storable-propellant rockets for the first and second stages. Pressure-fed boosters like this are heavy and relatively low-performance, but also relatively simple and cheap. The heavy construction required for the large high-pressure tanks makes them readily recoverable and refurbishable.

In 1993 Boeing designed a modular heavy lift launch vehicle for a range of space launch missions. The core vehicle was based on Shuttle External Tank components, with a multitude of SSME’s at the rear (in two recoverable pods). Shown here are some basic launchers built from these components, being used to launch  parts for a lunar mission into Earth orbit. The Shuttle is shown with the solid rocket boosters replaced with the new core vehicles.

From sometime around 1963, a few photos of wind tunnel models at NASA-Langley. Shown are a range of Dyna Soar models, from pre-Dyna Soar “HYWARDS” concepts to the initial Boeing 844 design to the final Boeing Model 2050E configuration.
