Before the advent of cannons, ramming the other ships was the main method for taking them out (other than burning or boarding). The reason for this, of course, is that space ramming depictions are probably based on the Space Is an Ocean mindset, and the cultural memory of Real Life naval tactics of the ancient world. Sadly, things are never portrayed like this. This ought to lead to a tense cat-and-mouse game as the rammer tries to close the distance and compensate for the target's evasive maneuvers, and the target tries to stay clear long enough to score a killing hit - the ramming ship is essentially a large missile, and the target would be performing a High-Speed Missile Dodge. At realistic space combat distances (hundreds if not thousands of kilometers), the target should have plenty of time to see the attempt coming and either blow up the ramming ship or dodge out of its way. That said, there is one challenge for a ramming ship, which is reaching the target in the first place. Though interestingly when one of the ships weighs a lot more than the other the people in the bigger ship might only be knocked off their feet, so for a bigger ship ramming into a much smaller one at 10-30 m/s could be a great tactic for taking out enemy crews while leaving both ships intact. Likewise, small fighter craft often smash into bigger ships with no visible effect, when they ought to be wreaking massive devastation.Īnd then there's the momentum, even ramming at a few tens of meters per second could create enough force for the people inside to slam into the walls at dangerous if not lethal speed. Survivors are not unknown, and the effect is usually depicted as 'Ship A crashes into ship B and ship B crumples and breaks apart in slow motion,' where it should look like, and is only rarely is portrayed as, 'Ship A crashes into ship B and both ships are vaporized in a titanic fireball'. In fact, the usual mistake is not to make ramming work too well but to make it work not well enough.
