    Hermes class is the legacy scout design from the 2260s. Refitted several times since construction, the ST595 design has constantly been updated to the latest scientific standards. Several vessels were lost during the first couple of decades of useage, the limited defensive capability of the scout design made it vulnerable to attack from threat vessels. Having said that, the Hermes class was responsible for the most exploration and cartographical achievements during the same period. The rapid construction time of the design made it invaluable for the exploration of virgin territory. Starfleet soon put in the request for more vessels of the class.

    Marketed as the base model scout (ST) for Starfleet, the Hermes class has been the most successful scout class in the fleet since the 2250s. Developed from the famous Einstein class of the early 23rd century, NX-585 was the first in what was to be hundreds of scout class vessels derived from the successful prototype. The Hermes class has been the basis for many designs including the Monoceros, Cygnus and Pillinger classes.

    Hermes class has extensive scientific laboratories and the trained personnel to make the scout an autonomous vehicle of pioneering exploration and study. Despite the promises that the Oberth class succeeding the Hermes class, this did not happen.

    Hermes class derived from Einstein class is from the Kelvin being from the 2230s and the Hermes more from the 2240s/50s.

    In 2312, the Hermes class is still the primary heavy scout vessel, supported by T'lani, Trista and Oberth class scouts. The Federation science council uses these vessels for the full range of scouting duties. Oberth class has taken over in the science vessel role, the Hermes class has more range, supplemented by the T'lani class.

    The mark 7-B Monoceros class scout was designed to escort diplomatic and cargo convoys, especially on solo missions. During wartime the Monoceros class was designed to accompany every flagship as their long range eyes and ears. Refitted with the large active OC5889S for improved sensor performance, although the passive sensor is used to avoid making a target for the enemy.

    3 batches:

  • Flight I NCC 601 2280s Hermes refit with LN-64.
  • Flight II NCC 4101 - 2290s production run to boost scout numbers
  • Flight III NCC 9143 - 2290s with extra sensor arrays on ventral hull. Pillinger class,
  • Flight IV NCC 10734 - 2300 second Pillinger batch with extra sensors.

    The Monoceros/Pillinger class scouts are the principal scout class vessels for Starfleet in the late 23rd and early 24th century. Derived from the successful refit of the Hermes class scout, the Monoceros class had additional sensors on the dorsal surface of the primary hull.

    The later Flight III Monoceros class had further sensors and scouting facilities added to the ventral surface of the primary hull to produce the first of the Pillinger class. With the drive on exploration that was started in the 2280s and highlighted by the Tabula Rasa Incident, Starfleet had a new impetus to upgrade their scout and science vessel fleets.

    Super scout connection

    The late 2280s saw the Kestrel super scout (SS-3000) project that was devised to provide a fast scout with cutting edge sensor capabilities. Monoceros class U.S.S. Pegasus trialled the Big Ear sensor equipment that was later fitted to NX-3000. As with the following Phantom project, the Kestrel class role was clarified to be one of supporting tactical assets in intelligence gathering and providing real time information to fleets.

    The Monoceros class pioneered this supporting role to the fleet in the 2280s and early 2290s, superseded by the Kestrel class vessels as they came online. With the Monoceros class freed up from this fleet support role, they became the frontline scout vessels for the scientific arm of the Starfleet. The Advanced Starship Design Bureau continued to work with private corporations to outfit the Monoceros class vessels with the latest sensors and laboratory equipment.

    Recent history

    Away from the conflicts of the 2290s, the Hermes and Monoceros class scouts continued to further the pursuit of science and exploration, pushing back the Federation frontiers. As with all exploits of exploration, there were risks and vessels were lost at the rate of one or two per year over the 2290s, including many that were the first to encounter the Tzenkethi Coalition in the Alpha Quadrant.

    The production line for the Hermes/Monoceros class scouts has never ceased since the class first emerged in the 2250s. The need for extensive sensor arrays has prevented the addition of a second warp nacelle in the Akula class destroyer style. A second parallel nacelle has been tested, however the new Kestrel class duplicates this feature more successfully.

    This is a short-lived experimental refit of the Hermes class from 2270. These vessels would transfer flag staff and ambassadors to and from Starbases and important meetings outside of Federation space where a larger, armed vessel would not be tolerated.

    These vessels were later refitted into Hermes (refit) class scouts.

    They are a Sector Emergency Mobile Command Post (SEMCP or "semcap") ship; not as capable as a Command Ship, for sector-wide or even national emergencies that require direct flag or diplomatic overview and participation, they will rush said parties to their destination.

    Thank you to my good friend, Andrew for building up the picture of the Cygnus class.



    Pillinger class NX-9143 - Monoceros batch 3.



    Attrition of the batch 1 Hermes class, and the success of the Monoceros class batch 1 made the production of a more numerous batch 2 guaranteed. These scouts would follow the successful design laid down by NCC-601 and her classmates. The Federation Science Council decreed in the late 2270s that exploration and discovery were to be raised in the Starfleet list of priorities. This was assertion was made time and again during the Starfleet reviews that were to follow.

    The OC5889S array made the Monoceros class a formidable scouting opposite to the equally successful Akula class destroyer. By the late 2280s, shipyards across the Federation were producing Monoceros class scouts for both Starfleet and private corporations. By 2289 this batch 2 derivative was evolving still further with the assistance of sensor arrays from Bold Futura and Massive Dynamic. This Hermes class derivative was to have sensors fitted on the ventral hull surfaces with which to be able to survey planetary surfaces in more detail.

    Author's notes:

    The idea with the Pillinger class was to update the Hermes for the modern Starfleet. I asked my good friend Andrew Brown to add Constellation class dorsal sensor pods onto the existing Monoceros class design. The idea was that this was the larger science partner to the Oberth and T'lani class scouts. Unlike those two designs, the Pillinger is able to have outboard sensor arrays and have a very functional look.

    Whereas earlier scouts are named for mythological beasts and celestial bodies, the Pillinger class are named for scientists, discoverers and explorers. An endless list of names if ever there were one.




    Oberth class was a promising science vessel, but was limited by crew numbers, endurance on station and a small hull that did not lend itself to outboard sensor arrays. These Hermes class derivatives possessed a longer range and a hull that could fit outboard sensors. The first of the batch 3 Monoceros class, U.S.S. Pillinger NX-9143, emerged in the 2290s with additional sensor arrays and specialised crews that could be tailored for the mission.

    The new design soon proved its worth in the Tabula Rasa campaign, displaying its superior skills in mapping planets and surveying their lifeforms. This helped in the Metar and Taubat missions. The Interstellar Concordium Pacification War also highlighted the usefulness of this scout class. Away from the conflict, the Hermes class has shown that it can continue to develop and modernise. Well over three hundred vessels are now in service with more under continuous construction in many yards across the Federation.

    Author notes:

    Pillinger class, Monoceros batch 3, is named for the famous British scientist Colin Pillinger, who was a founding member of the Planetary and Space Sciences Research Institute at Open University in Milton Keynes, principal investigator for the British Beagle 2 Mars lander project and played a pivotal role in the Rosetta mission. He said "I was a disaster as a science student", yet he turned out more than alright.

    The quote that best sums up why he is such an appropriate name for this scout class is this: "As an organic chemist, turned geologist, turned astronomer who uses isotopic analyses to unravel the origins of life, our planet, the solar system and the stars, I hope I have something in common with the versatile men who were early Gresham Professors. The subjects which I research already enjoy popular interest; by combining them to produce a story of life told from the genealogy of its elements, my aim is to appeal to the widest possible audience, using an interdisciplinary approach to attempt to unravel the time-honoured puzzle, where do I come from?"

    I wanted to make sure that Starfleet has science vessels in large numbers and together with Oberth class and the larger Constellation, Renaissance and Excelsior classes, this would be the primary science vessel. In this case, as a scout.
