“ ~ Model shop manufacture covered the production of models, apparatus, and parts to support the research and development programs. In November 1951, it took over the ad- ditional responsibility for ordering, assembling andtesting of TX and TU weapons. The model shop had 180 employees on July 1, 1950, and was housed in scattered temporary areas of approximately 16, 000 square feet with limited facilities. It completed its move into the new model fabricating building in June 1951, and now occupies 97, 000 square feet of floor space. New facilities have been provided and there are now 600 trained employees. With the increased emphasis now being placed on research and development and the transfer to other contractors of free-fall implosion and gun-type weapons, the manufacture of TX and TU units will be transferred to the weapons assembly shop, leaving the model shop free to devote all of its efforts to the serving of the research and development program. The weapons assembly shop which assembles, tests, and packages some of each Mark weapon, has similarly grown from 250 to 550 employees, and its floor space has increased from 85, 000 to 175, 000 square feet. It is housed in a new production building which was completed and occupied in January 1951. The value of production, including deliveries to research and development amounted to $23, 664, 000 for the fiscal year 1951; $60, 919, 000 for the fiscal year 1952; and $97, 700, 000 for the fiscal year 1953. Substan- tially all major production programs at Sandia were met during this three-year period. DELETED Seag With the transfer of quantity production of free-fall implosion and gun-type weapons to other AEC contractors, the responsibilities of this shop will be confined in the future to the production of: a small number of free-fall implosion weapons required to prove weapon design, missile warhead installations, and field test and handling equipment. This shop will also be available for emergency retrofit, modification and repair of stockpile materials. ALGO Production Coordination Emphasis during the past three years has been placed on: release of designs based on maximum possible standardization and ease of manufacture, strengthened liaison activities with the manufacturers, and adequate inspection and quality control. This was made necessary because of the greater variety of weapons and the transfer of production ‘responsibilities of free-fall implosion type weapons to other AEC contractors. Standard-. ization has been established through uniform drafting methods, materials, process and apparatus specifications, and the increasing selection and use of commercial materials. To the extent that they are available, military specifications have been employed. Not SP
