The powerful F-1 engine, as an enamel pin! 5 of these engines powered the first stage of the Saturn V rocket, currently the only rocket to have ever taken humans to the Moon. Producing 1,522,000lbf at sea level, with a specific impulse of 263s, these engines still retain the title of the most powerful single combustion chamber liquid-propellant rocket engine ever developed! What an amazing piece of rocketry and history that you can now wear as a pin!
