• DOD to develop the shuttle's Interim Upper Stage. - . An Air Force Program Memorandum on DOD Space Shuttle Utilization was completed that assumed the DOD would develop the shuttle's Interim Upper Stage (IUS) needed for high energy missions..

• IUS studies begun. - .

  The Air Force awarded firm-fixed-price (FFP) level of effort contracts of about $635,000 to $640,000 each to Martin Marietta Corporation, Lockheed Missiles and Space Company, General Dynamics Convair Division, The Boeing Company, and McDonnell Douglas Astronautics Company for nine-month IUS System Study efforts.^ These companies had in-production, existing operational upper stages and the studies would provide baseline data for future acquisition efforts.

• Interim Upper Stage for use with the Space Transportation System. - . Dr. Walter LaBerge, Assistance Secretary of the Air Force for Research and Development, announced an Interim Upper Stage to be developed for use with the Space Transportation System..

• Contract for validation phase of the Interim Upper Stage. - . A contract was distributed to the Boeing Aerospace Company for the validation phase of the Interim Upper Stage development program. The contract carried a target price of $21 million..

• IUS 85-second test firing. - . A rocket nozzle for the IUS was subjected to an 85 second test firing at the Rocket Propulsion Laboratory. The test was successful. A second successful test took place on 15 July..
