How is Smartbomb Range Calculated?

One of those dumb questions I just had to jump on SiSi and test it out - indeed from the screenshot below you can see that the target is being damaged even though the ships centers are more than 5km apart. the range of the bombs is computed based upon the gun range and so the range is boosted by the collision radius of the models. This means that the 'volume of effect' (not area of effect - that's 2d) is larger for larger ships, and pilots putting smartbombs on their capitals are getting more bang for their buck than those who use bombs on their dinky little battleships.
