Perhaps we do differ. I disagree with Jonathan that there are things that a Ghost can do that a Shark cannot. Sharks can carry platforms. The only thing I personally think that sets a Ghost apart from a Shark is that a Ghost is stealthier simply because it is much smaller. I think the MA intentionally built the smallest possible spider driven ship for maximum stealth. Of course they did.
Here's the thing. For a Shark to have been a test bed and training for an LD, it has to be able to perform as close to an LD as possible. If a Shark cannot provide its own fire control, then as a warship, it is useless. Ditto for the LD.
A Ghost is sent for reconnaissance on the very difficult systems like the MBS where there is always rush hour traffic. So premium stealthiness is required. Every last bit. So a Ghost would be sent. That is only my opinion.
Rush hour traffic in first tier systems compounded by their advanced arrays etc , would be a purely Ghost operation. Or rather, better suited for a Ghost. IOW, a weak enough task for a Shark, but made for a Ghost.
I understand the notion though. I think Jonathan sees Ghosts as very specialized ships with specialized hardware and sensors, etc., much like Harvest Joy which I imagine is chock-full of specialized hardware and sensors as well. But if warships don’t have the same then they are useless.
I also assume Jonathan was pointing out that since Sharks were not meant to be used operationally that the specialized hardware would not be wasted on them. But then, how could they be used as training vessels for LDs?
It seems that the addition of the fire-control platforms used by the Ghosts in the Sharks would bridge the gap.
Although I think the LDs as well as the Sharks would use much smaller, specialized, even slower, spider-driven probes instead of platforms.* But for close in attacks neither are needed. Just my opinion.
*And or a specialized computer like Behemoth.
