Upgrading Stargate's BC-304

What would an upgrade package for the next flight of Stargate BC-304s look like?

Double the hangar and railgun capacity, retain missiles and Asgard plasma beams, and protect the bridge and engineering spaces against boarding or transporter access.

The proposal doubles hangar space and railgun fittings while retaining missiles and Asgard plasma-beam weapons. The bridge moves firmly inside the hull, with protection against enemies beaming directly into it. Gate and ring-transporter access would be kept away from both the bridge and main engineering. These changes combine more aviation and conventional defensive fire with tighter control of access to essential command and machinery spaces.
