Morpheus Class Loadout: This Cruiser was built after the fall of the Asgard Race. Her hull was designed with Asgard plasma conduits laid across various sections of the ship to allow Asgard based weapons to fire at greater capacity.
Time dilation basically speeds up time or slows it down in a small area. The advantages of which can seen in the Stargate SG-1 series. When the human shaped replicator were first encountered by the SG-1 team, a time dilation field slowed down their operations enough for the Asgard to attempt a permanent solution to the problem. Also, in the last episode of season 10, the asgard modified Odyssey used a time dilation field to stave off its destruction by superior enemy forces.
