Continental Arsenal OGR-5

There's no way to get close to it now, it's on high alert. Anything that gets within 10 kilometers gets turned into paste.

The Continental Arsenal OGR-5, also known as the Ogre rotary cannon, is a five-barrel 280kJ Oström rotary cannon designed and manufactured by Continental Arsenal. Its primary goal was to engage and destroy incoming ordnance, be it projectiles, missiles or even aircrafts, to serve as a point defense weapon. The OGR-5 performs this task admirably, but is known to consume a large amount of power for short durations of time, making it difficult to mount on mobile platforms such as vehicles.

The OGR-5 was designed in 339 in response to a request for improved anti-missile defenses for the Vestan Aerospace Defense Force. The weapon was subsequently adopted two years later after numerous trials and modifications. After some field tests and minor encounters in the Ceryx System, the OGR-5 proved to be vastly superior to the previous anti-missile weapons used by the ADF. Using next-generation rapid-charge capacitors, ultra-high density Oström cores and superconducting coils, the OGR-5 could fire up to 1 500 rounds per minutes at ranges of up to 15 kilometers with extreme accuracy.

Design

Unlike most weapons, the OGR-5 is made of two main systems: the power supply module and the weapon system module. While the latter is a relatively simple assembly of five Oström cannons arranged into a rotary system, the former is where most of the Arsenal's R&D truly shined. Using next-generation capacitor banks and resilium-based heat sinks, the power supply module could provide enough energy to the weapon system module for more than 15 minutes uninterrupted, should it receive enough power itself. This made the OGR-5 an extremely reliable anti-missile defense system, but one that could only be installed on ships and stations with power plants capable of feeding such weapon systems.

Variants

OGR-5-V

The Void variant of the OGR-5 uses external radiators to vent out excess heat from its barrels. This allows it to fire for up to two minutes uninterupted before reaching critical temperatures, after which the integrated liquid cooling system is required to bring down the temperature to acceptable levels. The weapon's voracious power usage and extreme lethality is what gave it the nickname of Ogre cannons.

OGR-5-G

The Ground variant of the OGR-5 uses simpler thermal fins to vent out excess heat, as well as the integrated liquid cooling system. As powering the OGR-5 is difficult, the G variant only has three barrels to reduce its power consumption, sacrificing some lethality for the ability to mount it on defensive emplacements and vehicles. Even then, supplying the weapon with its optimal power requirements remains a challenge.

History

The OGR-5 was initially designed at the request of the Aerospace Defense Force for improved anti-missile defenses. Taking the lessons of the previous conflicts and engagements of the ADF with hostile forces, the Arsenal quickly came up with a first prototype less than a year after the request. Performing its own trials for several months, the Arsenal improved what would become the OGR-5 over several test phases before announcing its completion in 339. The weapon then entered trials performed by the ADF for two more years before being adopted. Initially mounted on several test bed ships, the OGR-5 proved to be a remarkable weapon, nearly perfect in its role were it not for its enormous power consumption.

Despite this major flaw, the weapon was quickly retrofitted to many ships of the ADF, albeit in smaller numbers than the predecessors it replaced. Continental Arsenal continued to improve the weapon's power efficiency, delivering several updates over the following years, but the weapon had already earned its reputation.

Operators

Vestan Defense Forces

The sole operator of OGR-5 cannons are the Vestan Defense Forces. The weapon's operating costs and enormous power requirement means that only government assets are suitable users.
