First round... I'm grabing a photo off of bing for what you are to fight. And the photo of what your fighting, is this.

Yah yah I know what your thinking, didn't they decommission those in 1998? Weal, you don't get it..... yes, it dose I admit, have 1998's technology.... but it also has technology from 2390, and also 2541, but its powered by a forerunner technology power core, and it has pulse laser turrets. Its armor is made of a blend of liquid armor gel, diamond steel, titanium AA hunter shield mettle and ceramic plating. Its length is 1220ft from bow to stern, its speed is 48 mph, it has a crew of 2874 warriors, (what kind is purposely not said.) And it has a cargo capacity of 54200.220.800.10.5 tons. But their is only 1 of them.
Now, hear I am going to have you figuratively slay the dragon with a push pin for a sword and paper plate for a shield. Hear is what you have to fight back with
Rules, this is all you get to fight that thing with. But, you can decide how many you are going to send to fight the thing.
Question is: How many wraiths will it take to fight that battleship. Let the show begin.
Edit: Go ahead and use something that isn't a wraith, but it has to be from the halo universe.
