Mockingbird - Jordin Kare gave a review of this fascinating vehicle design that he and colleges at Lawrence Livermore Lab developed in 1994. The vehicle's only purpose was to prove that single stage to orbit and return was feasible.
The bowling pin shaped vehicle stood only 5 meters tall. It was 1 meter in diameter at the bottom and then tapered to a sharp point at the top. It took off on the thrust of 8 engines designed for low altitudes and then switched to a single central engine for high altitudes. The oxidiser was 98% H2O2 for JP-5 fuel.
A super lightweight approach, such as very thin walls that served as both hull and fuel tanks, would be needed to achieve a dry mass of 75kg and a liftoff weight of 1500kg. Since it was only meant as a SSTO demo, the fact that it could only take a kg or so of payload was not important (they also called the vehicle the "Bricklifter"). For return an unbrella like shield opened up on the bottom to act as an aerobrake.
The project was actually approved by the missile defense chief at the time and would have cost about $20M. But the project was canceled when the BMDO leader was transferred.
Kare says there will soon be a document posted on the web that gives details about the project.
