American intercontinental ballistic missile. The Ares single-stage, liquid-propellant ICBM was the objective of propulsion studies at both Aerojet and Rocketdyne.
The objective was to attain a high enough specific impulse through use of high chamber pressure and a deployable nozzle extension to obtain intercontinental or orbital performance using a single rocket stage. The project was halted when Secretary of Defence McNamara decreed that all future ICBM's would only use solid propellant.

VTOVL The concept of a reusable single-stage-to-orbit Vertical Take-Off Vertical Landing (VTOVL) launch vehicle that would reenter and return to its launch site for turnaround and relaunch was first proposed by Philip Bono in the 1960's. The appealing simplicity of the concept has been offset by the technological risk in developing it. The problem with any single-stage-to-orbit concept is that if the empty weight of the final vehicle has been underestimated it will not be able to deliver any payload to orbit, or even reach orbit. Since weight growth of up to 20% is not unknown in aerospace projects, this is a very real threat which has made both NASA and private investors reluctant to invest the billions of dollars it would take to develop a full-scale flight vehicle.
