Archives for ships and fleets. 'nuff said. Most of the ships here are very very old and will not work in current versions of BSF or SM. You have been warned!
On the Vyper i see that the Dieterling is not in the middle, so i think you could fix that. And the aegis... Try to find a fitting colour for it.
Everything else is good in my opinion.
all of those ships are decent, but I'm really not liking the white aegis on the engines. it can be changed easily in the edit menu. of those, the gamma is my favorite, bu the weapons placement could use some work. they would look better in turrets, or integrated into the hull.
