This is a port used for docking of two spacecrafts. Due to its large radius it provides a much more rigid connection than the small-sized Clamp-o-tron Docking Port resulting in a lot less wobble. This makes it the preferred choice for docking very large and heavy vessels. Otherwise it is functionally identical to all other docking ports, but a lot heavier than them.

Note that in order to dock two spacecrafts, both must be equipped with docking ports of equal size. When constructing a spacecraft, another part which is not a docking port can be placed on it. That part can then be undocked, but not redocked.


The Clamp-O-Tron Sr. is the result of intense and costly development to answer the problem of how to make docking connections more sturdy. Thanks to the brilliant suggestion of the staff janitor "why don't you make 'em bigger?", the public now can enjoy the sheer thrill of docking enormous objects in space.


Strength against pulling apart

The strength of docking ports is hard to determine. In real life the strength of a docking port is depended by many factors, basically if you are folding the connection or just pulling it. But who cares about real world here?

At a force of 100kN a little gap between the docking ports is formed. The gap is getting bigger with increasing force.
At a force of 1100kN the docking ports are about a meter apart. Relating to a stress–strain curve this would be the elastic limit.
At 1120kN (a little bit more than a J-2 engine used in the Saturn 5 rocket) the parts are moving slowly apart. This makes the game think the ship is getting longer. This is why the camera - pointing always the the center of mass - is moving. At a distance of about 70 meters the docking port are being ripped apart (letting the camera flipping back).

The force on a docking port within a space ship (e.g. when you are pulling something) is much smaller than your engine force because the part being pulled is going with you. To be on the safe side one can use as a rule of thumb that the port stress is the force applied by the mass of the part that is pulled. More accurate would it is the force of the part pulling minus the force of the part that is pulled.
