An Aellr design that pre-dates contact between the Confederacy and humanity, the Psirtas class (named after towns on the colony worlds of the Confederacy) was one of the workhorses of the Defence Fleet. The first human sighting of this design came in the calamitous days running up to the First Battle of Earth. The smallest of four ships that approached the planet, with its prominent missile launcher mounted to one side of the jump drive, Psirtas class was immediately categorised by the human defenders as a destroyer. Unfortunately this misinterpretation was one of a pattern mistakes made by both sides that would see the Confederacy and Earth blunder into the profoundly avoidable Contact War.
NOTE Given the ongoing political tensions between the Confederacy and Earth background have come from secondary sources and may not be entirely accurate.
The Psirtas class originate approximately fifty years before first contact; as with most Aéllr designs the class was intended to provide the Defence Fleet with a multi-role platform capable of performing search and rescue, personnel transport and internal security. As with all Aellr ‘warships’ of this period, any military role was of very much tertiary importance and little more than a fading relic of the Aéllr Reunification War of more than a century earlier. Intended to compliment the much larger Hinhle (Province) class cruisers, the Psirtas placed emphasis on acceleration over range.
The design can be divided into three main segment. The forward-most section, mounted the jump drive, main bridge and the two hard points for mission specific equipment. When serving in the military or internal security role, these would mount a turret, each one carrying a single plasma cannon. Alternatives to these fittings were shuttle hangars, high definition sensor arrays or docking arm. The point defence guns – primarily intended for anti micrometeorite duties – and the probe/missile launcher were permanent fixtures.
Mid ships was the centrifuge with two large pods. It is believed a small secondary bridge is housed within one pod but for the most part this space is given over to crew facilities. Several members of the class, usually when de-militarized have been observed with six secondary pods fitted to a large circular ring that connects the two primary pods. It is believed that like the forward hard points this a mission specific fitted when more living space is required.
Astern is the engineering section, protruding from the ventral and dorsal surfaces of which are the engine nacelles. The length of these is to allow the engine plume to clear the centrifuge during breaking manoeuvres. The decision to extend the engine pod in the vertical axis appears to be to facilitate the class’s search and rescue role, allowing the ship to come closer along side another vessel while maintaining the same deck orientation. A side effect of this choice of orientation is that the ship’s profile in the broadside arc was considerably larger than would have been the case if the nacelles had been side mounted. This provides another clear indication how low a priority the class’s military role was. The ship’s radiator panels are housed in the broadside circular assembly which when deployed resembled paddlewheels, leading to the class’s human nickname ‘pedalo’. Physical protection was limited to anti-radiation shielding while sensors systems took the form of small clusters scattered across the main hull.
Overall the Psirtas class with its emphasis on adaptability was very much a conservative design, following with standard practice of the time. The only significant break from previous practice was the absence of a raised bridge, a feature of Aéllr government ships since the Reunification War.
By the time of first contact between Humanity and the Aéllr, the Psirtas class were in their middle years, with the expectation of at least another three decades of service. While an exact number constructed is not known, it is believed to be in excess of thirty, although by first contact the earliest members of the class had been withdrawn from service. When the Aéllr taskforce was dispatched to earth a single member of the class was included to act as a scout ship. The decision to include this vessel with the ships that directly approached Earth, seems to have been born of a genuine belief that the force would face no opposition. In fact the Psirtas was to prove very much a weak link. An early direct hit to the ventral nacelle rendered the ship virtually uncontrollable while the two point defence guns left a large blind spot astern. The taskforce’s attempts to support the ship meant that it neither closed on Earth nor retreated out of range between waves of human fighters.
In the aftermath of Earth the casualty averse Defence Fleet appears to have come to the conclusion that the class was too fragile for front line operations. For most of the rest of the war the class remain within the Confederacy’s borders, covering for the Hinhle class ships that were being used to prosecute the war against Earth. The Psirtas would see direct combat when the cruiser Onslaught entered Confederacy space in the last year of the war, the Battle of the Three Systems being the most notable event of this campaign.
Post war it would appear that the remaining members of the class were returned to their civil role. It is believed that at least a dozen remain in service with the Defence Fleet with perhaps half as many again now owned either privately or by individual colony worlds. However sources indicate that the Defence Fleet no longer rates the class as part of it’s fighting strength.
Author’s Notes: As the first alien race humanity encountered, with the war between them being the background event that did the most to shape the Battle Fleet Universe, the Aéllr are a very large part of the setting which I’ve wanted to explore for a while – especially since describing in Volume Two of Ships of the Fleet the human Contact War cruisers. Most of my ship designs are fairly brick like, in part because it is how I imagine then and in part because with the software I have access to, they’re a damn-sight easier to make. But I wanted to explore the possibilities of a design using much of the same basic technology but with a very different set of priorities at least as far as the limits of my talents and my computer processors capabilities.
