Necron Doom Scythes work very similarly to Ork Fighta Squadrons, in that they can deal damage to the enemy ship's hull ignoring shields. These might be the two types of fighters in the game that do this, but I noticed the Doom Scythe text must have been changed in the last patch. When this game came out, their text properly reflected this, and read very similarly to the text on Ork Fighta Squadrons. Now this is how the two tooltips compare:

As you can see, the Doom Scythe skill now gives almost none of the relevant information that it should give (essentially it should be a copy and paste of the Fighta Squadron text).
