OK we all know a Borg Sphere would obliterate pretty much any combination of Kancoll ship girls you could come up with.

So there are restrictions on it.

1. Ignore any feats except the lowest end for its weapons are allowed

   1. Things like this from First Contact are good. (keep in mind those are moving at like 100 kps)
   2. Things like this are not ok.

2. Its KE durability is based on three feats from the movies. Though also remember that the Borg Sphere is 400-600 meters in diameter and can remain functioning with the vast majority of it destroyed. So even with much lower than normal durability it can still take a beating.

   1. First feat
   2. Second feat
   3. Third feat

3. It is not allowed to use any any exotic tech (like transporters) or weapons of the week.

   1. No it cannot set is phasers to stun (yes ships can actually do that) and wide beam the whole Kancoll fleet.
   2. No it cannot use transporters in a direct offensive manor.
   3. Things like shields and tractor beams are fine.

4. The Borg Sphere must remain in contact with both the water and the atmosphere and is limited to 60kph.

   1. So no full submarine sphere and no flying.

Realize that this is a writing prompt and if you write something like "lol they get one shot", the thing you are writing is probably pretty bad and against the spirit of the prompt.

The fleet of Ship girls will be

Yamato, Kongou, Kirishima, Atago, Fubuki, Shimakaze and Destroyer Squadron 6 (1 Battleship, 2 Battlecruisers, 1 Heavy Cruiser, 6 destroyers).

Location the middle of the pacific.

Combatants start ten kilometers apart.
