Photograph of "Battleship" tanks, which simulate the configuration of an atlas ICBM, feeding propellants to the engine being test fired, ca.1955. In the left, a large tower can be seen exposing five platforms with staircases, pipes and a rail surrounding each one. Its highest point is formed by a cylinder-shaped machinery(?) with two circular balconies surrounding its top area. In the left, by the bottom of the tower, different tones of smoke (steam?) are being ejected from the tower's pipes and from underneath it. In the right foreground, the curve of a paved street is noticeable showing a small cabin made out of concrete; a rail delineates the street and a pipe extends along. A rocky mountainside fills in the backdrop. Photoprint reads: "Battleship" tanks, which simulate the configuration of an Atlas ICBM, feed propellants to the engine being test fired at Rocketdyne's propulsion field laboratory in the Santa Susana Mountains. Stands like the one shown are capable of withstanding one million pounds' thrust, transmitting the enormous power of the Rocketdyne liquid propellant engines deep into bedrock."
