bens “yr Port Hl Weapons WEAPONS PRODUCTION wm The number of nuclear weapons produced during the July-September quarter was slightly greater than in the preceding quarter, although somewhat less than had been scheduled. The delivery rate attained in September indicated that the production rate could be expected to continue to increase and that the stockpile objective established for June 30, 1959, would essentially be met. Production was highlighted by the startup of Mark 28 thermonuclear bomb production. Difficulties In obtaining certain mechanical and electrical components have revealed that initial production schedules for this and other new weapons systems were too optimistic. New weapons first produced for stockpile during the quarter were: 1. The Class D thermonuclear bomb, Mark 28 Y1, with a yield af anda weight of 2,000 pounds, et “xy Cy 2. The Mark 49 Y1 thermonuclear warhead for the Intermediate Ra: ge Ellistie Missiles, Jupiter and Thor, witha yield off-: RS pe a weight of 1,600 pounds, and ‘ pELhe” \ 3.
