ABOARD USS JOHN C. STENNIS (October 12, 2000) -- Airman Candance Laplaca measures the internal diameter of the steam catapult cylinder aboard USS John C. Stennis (CVN 74) using a diameter gauge. The diameter gauge or tree measures the diameter of these cylinders at multiple points. The cylinders are used to power the catapults that launch aircraft from the flight deck. They endure years of temperature changes, stress, and constant exposure to heat and steam, which causes them to warp, or lose their roundness. Every 2000 launches, the "slots" of the cylinders are measured to determine if the cylinders must be "pinged", or hammered, back into shape. Once determined necessary, these measurements are taken by catapult maintenance personel to determine the exact current shape of the cylinders, and what actions should be taken, in order to restore them to perfect cylinders. Stennis is in her homeport in San Diego, CA after returning from a routine six-month deployment. U.S. Navy photo by Photographer's Mate 3rd Class William C. Rowlett. (RELEASED) |
