Original set of Master Schematics from Grumman Aerospace titled, EA-6B Expanded Capability Software Overview, as developed by Grumman for NASA as part of the Space Shuttle Development Contracts in 1972.
Grumman became a key player in space technology as the company designed and built the Apollo Lunar Module that was used for the moon landing. In the Post-Apollo era, NASA issued a development contract to Grumman under its new Space Shuttle program to design and develop an Orbiter vehicle which could be reused on multiple missions. These extremely rare original schematics are part of the master plans drafted by Grumman under the NASA development contracts. The plans are entirely hand drafted in pencil on a delicate ivory tinted trace paper which was a common medium used by engineers for drafting technical documents. This document still has portions of border drafting tape that was applied to the surface of the drawing. These extremely rare original schematics are part of the master plans drafted by Grumman under the NASA development contracts. The plans are drafted on translucent polyester/plastic drafting film which was a common medium used for creating master drafting documents during this period. The full description of this diagram is 'Orbiter Vehicle Hardware-Software Integration' with sub-diagrams titled, 'Systems Level I Diagram; Subsystems Level II Diagram; Software Overview Diagram; Integrated Functional Flowpath Diagram; and Systems Software Diagram.' There is a notation cross referencing drawings: B3L01080-1104 (Life Support); B3L01080-1105 (Main Propulsion); B3L01080-1103 and B3L01080-1106 (Reaction Control).

Issued: Undated, but part of the Grumman development project created for NASA in 1972.
Dimensions: 11" x 17"
