EarthForce Capital Ships
Captain John Sheridan commands the EAS Agamemnon. EarthForce consider him a war hero, but the Minbari are deeply suspicious of Sheridan. They call him Star-Killer, because his defeat of the Minbari War Cruiser Drala Fi (the Black Star) was by devious, underhand means. He may be a political liability.
Nova Class Destroyer
At the time of the Earth-Minbari War, our biggest capital ship was the Nova-class dreadnought. These ships were massive gun platforms, built at the height of pulse-cannon technology. Like the later Omega-class, the Nova-class was constructed by Rocketdyne. I guess you can see the family resemblance: the Nova has the same fighter bay, jump drive and fusion engines.
What you can't see here is any rotating mid-section - that was only introduced later, to simulate gravity in the command centre. So, you had to strap yourself into zero-g seats for the duration. They experimented with rotating sections at the time of the Earth-Minbari War, but didn't introduce them as standard until the EAS Achilles, the first ship of the Omega-class, rolled off the production line after the War. There were problems getting the rotational drive to work. But now that we've got simulated gravity, we can extend our patrols for months, maybe even years.
