I saw it in a couple stations. I'm almost sure that I saw it in a station in Alioth, and it's very likely that a station in Sol sells it too (both these systems are faction-aligned, though, so you need permits from the Alliance for Alioth and Federation for Sol).
It's supposed to be a passenger transport vessel, so a future patch may introduce passenger transportation quests or tasks. Anywho, it's flyable, has a very luxurious interior and even has 2 medium and 1 large weapon hardpoints. The stats are a bit alike to the Imperial Clipper, but with a different combination of Internal Compartments, one less Large hardpoint, less "practical" maneuverability (both are listed as 2, but the Clipper can be quite nimble in the right hands), less default shields and more armor. The remaining stats are quite close (they even share the same speed).
In a sense, you could use it as an exploration vessel (though with slightly less range than the Clipper, because of the weight. ~26 Ly jump range for the Clipper vs ~20 for the Orca), but be aware: that ship will be even more defenseless than the Clipper (which is indeed currently used as an exploration vessel).
