What is the function of launch lugs?

Launch lugs are small, typically cylindrical structures attached to the exterior of a rocket or spacecraft. Their primary function is to provide a stable guide for the vehicle during the initial phase of launch, ensuring it remains aligned with the launch pad and trajectory. They help prevent unwanted lateral movement and vibrations, facilitating a smooth liftoff and ascent through the atmosphere. Once the rocket clears the launch tower, the lugs are usually jettisoned or fall away.
