FYI you fluffed up your quote there mate.
Generally speaking you either transport new ships that haven’t been fitted or you contract wrap the things and stuff them in a jump freighter, which every Alliance of any size has a couple dozen of. Absolute worst case you can poke around with wormholes for a few days and jump a full freighter of stuff that way.
The only case where a ship like this is remotely worth using is where you somehow have a lot of unexploded hulls sitting somewhere fitted and you need to move them, the rigs are worth enough to justify a special purpose 4-5 bil hull just to move the things, and for whatever reason you can’t use a Titan to bridge stuff.
The two cases I can think of where that’s remotely sane are an aborted deploy by an alliance where for whatever reason your Titans are unavailable or at huge risk but somehow a jump freighter full of ships isn’t, or an alliance so small they can’t afford to lose the rigs but somehow can afford to risk a 4-5b hull.
Those are so niche it’s unreal.
Oh lets not forget that the base Bowhead can only fit 3 Battleships, so what you’re probably looking at here is BC or smaller hulls, and a Jump Freighter can still fit like 10+ Cruiser hulls unpackaged, so you’re talking about investing in a 4-5b ship for a niche use and basically a savings on jump fuel…
