“There were two types of catapults, one was powered by compressed air and the other was by a 5 inch shell with gunpowder, and the one with the 5 inch shell was much smoother than the compressed air.” Launching from a catapult “was just a very easy way of getting airborne. You didn’t do very much of anything outside of making sure you didn’t lose control of the plane.”
-Lieutenant Paul Wogan, Aviator
“The catapult was about 65 feet in length, was about 5 feet high. The plane, an OS2U 3 pontoon float plane, was seated in a saddle at the rear of the catapult. The saddle was attached to a steel woven cable, about 1 inch in diameter. This cable, through a block and tackle arrangement, was attached to a piston which was propelled by a 5-inch 55 caliber powder charge at launch time. The powder charge drove the saddle with the plane upon it down the catapult, reaching launching speed at the time it left the catapult of approximately 65 mph.
My position was rear pin man during launching. The plane sat on this little cart at the rear of catapult and to keep the cart from moving when the plane was revving up to be launched, there were two pins that came up from the catapult into the cart to hold it. Due to the noise from the plane, the launching officer would signal with his thumbs up for pins up or thumbs down for pins down to release cart. My job was to signal when pins went down so the plane could be launched.
One time we did a cross deck launch. The starboard catapult shot the plane off the port side across the ship. That condition put me out off the starboard side of the ship. When the plane leaves the catapult, it bounces some.
The catapult work was dirty, greasy and sometimes you had to eat lunch without even having time to wash the grease off your hands as a plane had to be launched. Sometimes by the time the plane was launched chow was over and we didn’t get any.”
-Cecil Jaudin Baker, Jr., F Division
Records in the Ship’s archives indicate that the catapults were removed when the Battleship was in ready reserve:
“Starboard catapult removal of from Atlantic Reserve Fleet on Battleships and Cruisers” dated 1949 and “Remove port catapult” to rearrange deck for helicopter landing facilities dated 1954. Catapult launching cars were removed in 1951.
