A piece of concept art depicting the AMROC Industrial Launch Vehicle 1, circa 1987. AMROC specialized in hybrid launch vehicles, and the privately funded and developed ILV was no different. What the vehicle looks like is a liquid propellant core vehicle with a bunch of solid rocket strap-on boosters… but what it actually is is a core made up of liquid oxygen tanks, surrounded by clusters of solid fuel motors. The motors were fed LOX from the core, firings together to create  a sort of plug nozzle using the aft end of the propellant tank to react against (though it appears the bulk of the expansion took place within  individual nozzles). When the first stage motors burned out, the whole thing fell off as a single stage.  The vehicle had four stages; stages 2,3 and 4 were made of different solid motors around a common liquid tank core. The whole stack was 82 feet long. It was supposed to have been able to deliver 1800 kilograms to a 200 km orbit from KSC, or 1350 kg to 200 km polar orbit from Vandenberg; a little over 1400 kg to a 1000 km KSC orbit or about 1050 kg to a 1000 km polar orbit. First launch attempt was to be in the latter half of 1988… that didn’t happen.
