Preliminary configuration freeze for the Apollo LEM

At a mechanical systems meeting at MSC, customer and contractor achieved a preliminary configuration freeze for the LEM. Several features of the design of the two stages were agreed upon:

Descent
four cylindrical propellant tanks (two oxidizer and two fuel); four- legged deployable landing gear
Ascent
a cylindrical crew cabin (about 234 centimeters (92 inches) in diameter) and a cylindrical tunnel (pressurized) for equipment stowage; an external equipment bay.

After "considerable discussion," Grumman agreed to begin designing systems and subsystems based on this configuration, bearing in mind that certain unresolved areas (the docking system scanning telescope location and function, and the outcome of visibility studies) would have a substantial effect on the final configuration.
