The Manned Spacecraft Center has issued its final Statement of Work for the Air Force Space Systems Division. Space Systems Division is, in this context, contractor to NASA procuring Titan II launch vehicles, as modified for the manned program’s needs. The statement, itemizing the tasks Space Systems Division is expected to do or provide, and on what schedule, and how acceptable performance will be measured, and so on, began being prepared by the Manned Spacecraft Center on January 3. The initial budgeting and planning were completed by the end of March. Though final the plan is subject to amendment.
Martin-Baltimore has submitted to the Air Force Space Systems Divisions a descriptive study and a proposed configuration for the Malfunction Detection System.

A report is being presented today to the Gemini Project Office regarding the abort criteria for the malfunction detection system. The report is presented by Martin-Baltimore and the Air Force Space Systems Division.
Martin-Baltimore has submitted to the Air Force Space Systems Division the document Description of the Launch Vehicle for the Gemini Spacecraft. This defines the concept and the philosophy for each proposed subsystem as well as laid out the design for the Gemini launch vehicle.
Air Force Space Systems Division has published the Development Plan for the Gemini Launch Vehicle System. Using experience drawn from the Titan II and the Mercury development programs it is estimated the development of the launch vehicle will require a budget of $164.4 million. This includes a contingency fund of 50 percent to cover cost increases and unforeseen changes.
McDonnell awards a $4.475 million subcontract to the Western Military Division of Motorola, Inc, of Scottsdale, Arizona. Western Military Division is to design and build the Digital Command System for the Gemini spacecraft. This is to receive in digital format commands from ground stations, to decode them, and to send the commands to the appropriate spacecraft systems. Two types of commands are anticipated: real-time commands for spacecraft functions, and stored program commands to update data on the spacecraft’s digital computer. The Digital Command System is to consist of a receiver/decoder package and three relay packages.
Air Force Space Systems Division awards a letter contract to the Aerojet-General Corporation of Azusa, California. This is to research, develop, and procure fifteen propulsion systems for the Gemini launch vehicle, and also for the design and development of related ground equipment. Aerojet was authorized to work on the engines on February 14th. Final engine delivery is scheduled by April 1965.
The Air Force Space Systems Division contracted today with the Aerospace Corporation of El Segundo, California, for general systems engineering and technical direction of the development of the Titan II booster used for Project Gemini. Aerospace itself had established a Gemini Launch Vehicle Program in January, and Space Systems Division issued a Technical Operating Plan for this support on February 18.
The Gemini Project Office reiterated its intention that Project Mercury hardware and subcontractors are to be used for Gemini. Using different equipment or subcontractors requires justification for each item.
Marshall Space Flight Center delivers to the Gemini Project Office a procurement schedule for Agena target vehicles. The Air Force Space Systems Division is to contract with Lockheed for 11 target vehicles. Space Systems Division is to put the Gemini Agena target vehicle program under the Ranger Launch Directorate.
Marshall expects that the delivery of a main engine qualified for multiple restarts will be in 50 weeks. This is an improvement in development time: the main engine is no longer considered the pacing item in the schedule for Agena development.
