Vindication-class Cruiser

The Great Schism was devastating to both sides of the brief but violent conflict, and devastated both fleets. What was left of the Sangheili fleet was destroyed when the Flood broke their quarantine, while the Covenant lost what was left of theirs in the battke for the Ark. After the Schism, both sides were forced to replenish their fleets before they could begin their campaigns against each other, and while a number of new ships were commissioned for the purpose, they were expensive and rare. For the most part, both sides acquired older ships that had been decommissioned and upgraded them to compete against modern technology. The Righteous Fury-class cruiser was one of these, and while it is classified as a cruiser, when it reentered service it barely matched the capabilities of modern Covenant frigates.

Quotes

 * "We should have salvaged it for scrap and little more. That's all its good for."
 * "There are disadvantages to both ourselves and the Jiralhanae using the same ship classed, but there are advantages too. We know all of their weaknesses, and our own can be...mitigated somewhat."
 * "I don't see what all the fuss is about, myself. It looks just like any other Covenant ship - big, purple, and oddly shaped."
 * "Its more than a century old. I daresay the humans would have refit it through their lives to keep up with progress, but under the Prophets there was no progression. Merely changed applications of them. What we called a cruiser back then we would classify as a frigate or destroyer today."
 * "Covenant ships always reminded me of seacreatures. You know, those ancient Terran ones with the wierd shells. Apparently this is based off a seacreature from one of the Covenant worlds. How about that."
 * "We had the pleasure of going up against one of these at Unmoving Virtue. Slow to manoeuvre, poorly armed and shielded, and its crew probably had no idea how to operate them. We destroyed them in a few minutes, and then moved on."
