Also what about this?
If Greystone Industries design and create the raiders and basestars then the Vergis Corporation create the Viper Mk1 due to public pressure on the worlds because of the increased Cylon population and the fact they are armed. Tom Vergis is out to get Greystone and dent his company remember?
When the War begins they Cylons already have a well built military infrastructure and can easily attack any of the Colonies at will. The Mk1 Vipers can only operate on or in orbit of the Colony they are stationed. The Vergis Corporation along with the new Colonial Fleet design and build a series of Destroyers and Cruisers but these are quickly overwhelmed by basestars and their fighters and also are prone to computer infiltration by the Cylons who over the course of their serviant lives became fully intigrated into the Net, a process defend by Greystone as a way of a Cylon continuously updating itself and its knowledge of its environment making a better slave/worker etc.
What is need is a large battleship and carrier as to provide fighter cover and cancel out the Cylon advantage. Enter the Galactica and her sisters, all built at the same time in orbit of one of the Colonies they represent. None networked computer systems, powerful offence batteries and hundreds of defence batteries, EMP generators, ten missile tubes, and 4 squadrons of the new Mk2 Viper and the new Raptor scout.
