The SD Ravana class of destroyers was first spotted in the nebula beyond Gamma Draconis, discovered by the GTCv Lysander and the GTCv Actium.
This class is probably the most powerful Shivan capital vessel, second only to the SJ Sathanas and maybe the SD Lucifer. In possesion of 4 forward-facing beam cannons, it can rip through the hull of a GTD Hecate or an Orion-class destroyer in under a minute, and take out smaller vessels within seconds. Its anti-capital ship weaponry make it a threat to any vessel, even one the size of the GTVA Colossus.
But the anti-capital beams come at a price. The Ravana-class is more vulnerable to fighter and bomber attacks than its brother, the Demon-class. Still, it would take a large number of squadrons to take out such a target.
FS2 Tech Room Description
The SD Ravana is a destroyer class GTVA forces have only recently encountered. It appears to be tasked with clearing out smaller foes, a mission for which it is well suited. It eagerly wipes out wings of fighters and bombers and also overwhelms cruisers and corvettes.
This thing is the GOD of what it was meant to do, unfortanately they made it much too big and bulky for the job, which is of course to take out hoards of fighters from all sides. it also has a fairly good anti cruiser armament though its hull plating is far to weak for it to excel at this.
The Ravana is scary-looking, but it's not tough. Weaker in terms of hull strength, and MUCH weaker in terms of turret strength then the Demon, the Ravana pays for its attack-oriented design with weak defenses. Indeed, fighters and bombers can range over the front three-quarters of Ravana's upper surfaces with near-impunity, and the lower-spine-mounted SAAA beam is placed too far back to defend the Ravana's main guns. It has a flak turret and another SAAA for anyone who comes up behind it, however. A capital ship behind a Ravana, on the other hand, is the Shivan destroyer's death sentence, as its engine subsystems are not strong and cover nearly the whole rear surface of the destroyer. Paired Trebuchets to the main beams the moment one of these enters the mission, then ignore it unless directed otherwise.
In The Great Hunt I was actually able to destroy the Ravana's main beam cannons before it fired on the Deimos corvettes, that's how weak they are. (Didn't make a difference, the corvette is destroyed by a SEXP). However, the Ravana, if used in its intended offensive role, can easily decimate a destroyer before being destroyed.
In a nutshell, the Ravana is useless if it is engaged from behind, and a light threat if side to side with another destroyer. This destroyer's saving grace is in its raw firepower facing foward. When deployed in a strategic position, or jumping in behind another destroyer, this beast will be your worst nightmare. Since most destroyers have their main beams facing forward and the odd ligher beam mounted aft (in the Hecate's case, two), it can dish out enough firepower to level the destroyer, and only take moderate damage. but this is only the case when the Hecate is alone. Roughly two wings of fighters, of any class, can knock out any anti-cap beam the Ravana wields & keep fighter cover on a friendly vessel. Just keep an eye on its beam cannons & you should get out all right. As stated before, the Ravana is no Demon, so it can't take as much punishment.
In Hindu tradition, Ravana is the antagonist of Rama, legendary king of ancient India. According to the epic poem Ramayana, Ravana is the king of the rakshasas.
