Both bunkers have raised floors, suspended ceilings, and latrine facilities. The easterly bunker will be utilized by Subtasks A905 and A909 for rocket launch control. The west-~erly bunker will be used by Subtasks A108, A109, A201, A202, A203, A6dl, A602, A603, A604, A606, A613, A6l4, A620, AIO1, A915 and A962 for rocket payload monitoring. The bunkers are designed to withstand overpressures of 6 psi on the sides and 3 psi on the roof. A 500 kva, 4160-480Y/277 volt, 3 phase transformer ''Tl" provides power for scientific facilities and a similar transformer ''T2" provides power for utility purposes. These two transformers may be tied together on the secondary side, if required, through a normally open circuit breaker. An additional transformer on the secondary side provides 120/208 volt, 3 phase power where required. Lighting is RF shielded and provides 75-ft. candles at bench level. Transformer 'T2" also provides 45 kva of 480 volt secondary power to Building 868. The existing electrical system provides 200 amps of 28 volt D.C. power; however, the D.C. distribution panel and circuitry will not be installed until firm criteria for this power is established.
