Notes

Multi-Warhead Missile: Basically a group of singular warheads on timed-release triggers designed to slip past enemy defenses or saturate a single target with destructive power, the multi-warhead missile allows a single missile to effectively become three, hopefully getting past any defensive fire the target might be able to muster.

Special: Although the launching missile system does not have the capability, a multi-warhead missile counts as a Rapid Fire weapon when fired.

HARM (High-Speed Anti-Radiation Missile): Intended for use against the Minbari, the HARM missile specififi cally targets enemy sensor systems, rendering them temporarily blind with electromagnetic interference. These missiles do not carry normal payloads but instead pulse with ECM emitters when near to an enemy ship.

Special: The HARM reduces the targeted ship’s Sensor rating by –1D(D) for 1D rounds if it ‘hits’ (in truth, the missile need only approach near the target for the effect to take place).

RMTS (Radioactive Monitor Tracking System) Missile: A forebear of the HARM, the Radioactive Monitor Tracking System (RMTS) missile variant was a very expensive attempt to coat a Minbari target with easily traceable materials that further attacks and scanners could home in on, eliminating one of their most notorious edges. The materials used were unfathomably expensive and the missile was nowhere near as effective as the test scientists believed it would be, which is why they were discontinued before the end of the Earth-Minbari War.

Special: Any ship hit by a RMTS Missile loses –1D to its Stealth rating for 1D rounds.

Description

The Olympus, first seen in early 2200 as a replacement for the smaller Laertes-class, served well for several decades until the Dilgar War, when logistical problems began to surface. The Alliance required an immense supply train into League territory, but keeping ammunition supplies available for both railguns and missile systems became a difficult challenge even with the Cotten Tenders and freighter support. It was an expensive, unwieldy and difficult ship to manage – but it was reliably so.

Olympus Corvettes were extremely uncomfortable vessels, not really suitable for long patrols or border defense due to unhappy crews and constant internal squabbles. In peacetime, they were generally treated as small monitors and left to guard bases or colonies just to give them somewhere to ‘stretch their legs’ when eventually necessary. In the aftermath of the Earth-Minbari War, many among EarthForce believed the Olympus was obsolete and needed to be replaced. It did not take long for the increased funding and shipbuilding influences to come up with a newer, less ammunition-hungry version which became much more popular amongst the navy.
