The T’Pari surveyors built in the 2250s exemplify the trusting spirits of the time, prompted by the lifting of the Klingon menace and the opening of the frontier for exploration once more. These vessels were constructed by Vulcan yet for Star Fleet use; even though they received NSP or NAR registries and served alongside numerous auxiliary cruisers, they were purpose-built designs that featured a proper balance of equipment and facilities for multi-year survey work in accordance with Exploration Command mission parameters. On the other hand, they carried virtually no weaponry and were very lightly shielded.
Key to T’Pari performance was a voluminous hull, necessary even when operating crews typically came from Vulcan. Using Procyon corvette structural members as a starting point only, the design expanded from a bow half-saucer into an elongated shape somewhat resembling the heavy frigate hulls. At the aft quarters were bays for medium exploration shuttlecraft, indispensable for the mission profile. Forward of the service hangars were processing rooms for planetary samples of various type, as well as extensive laboratories for their analysis. Holds between the hangars stored survey gear and ground vehicles, which could be moved down to the target planet via the heavy Class B shuttlecraft, or via a large combined cargo and personnel transporter just ahead of the holds. For lighter surface forays, two independently working GP transporters were provided, along with staging rooms and an immediately adjacent decontamination area and sickbay.
Further ahead at ship centerline was a general purpose laboratory complex, adjoining the main computer room and a briefing room, and linking to the athwartships research facilities as well. Superstructures amidships held both the necessary command facilities and versatile astrophysics instrumentation. The whole bow hemisaucer volume was thus available for crew and officer accommodation, offering relative comfort for the basic operating and research crew of up to 120 for great lengths of time. A number of specialists could be accommodated for shorter periods. Guest quarters could also be configured for atypical environmental parameters, to facilitate exchange of information with the broadest range of exotic lifeforms encountered.
Navigation and propulsion systems were detached from the mission hull in a manner typical of civilian vessels. Only the navigational deflector emitters were embedded in primary hull structures ahead of the shuttle hangars and laboratories. An engineering keel extended down from the mission hull, accommodating a horizontal twin-chambered linear reactor. Primary plasma was fed to an impulse engine at the tapering aft end of the keel, as well as up along an angled pylon into a single PB-35E engine, in an arrangement very much resembling the Remora escort propulsive system. Similar warp 6 maximum performance was provided, this time without the help of additional scooping coils. Endurance and persistence at survey target depended more on the secondary power systems, again benefiting from PA experience with tapping the main reactor at low power levels for extended periods of time. Battery backups were naturally available, and significant fuel reserves could be stored within the keel.
An initial flight of ten T’Paris was launched under Vulcan authority towards the rimward exploration zones in the late 2250s, preceding and preparing the even deeper surveys soon to be launched; VSS T’Plana-Hath would extend her mission all the way to the Galactic Barrier, performing detailed studies from a safe distance for several year-long stretches in a row. Out of the following twenty vessels, eight were given Star Fleet registries and operated in support of specific Exploration Command programs. These vessels were upgraded in 2262-64, theoretically now carrying the subclass name Thuringia although few actual modifications were made to the ships proper. The increase of some 850 tons of mass came in the form of an expanded FTL sensor suite, required to support modern charting operations. The mission profile of the upgraded ships did tend more towards astrophysics, even if the ships were fully equipped for planetary surveys as well. No major changes to propulsion or power generation were warranted during the decade of successful operations, and general overhaul periods between three-year cruises seldom exceeded three months. No shortcomings in other fields made themselves evident, either, and all vessels returned safely when the surprise recall orders were issued in 2268.
Shut off from deep space by policy changes, the T’Paris still made themselves useful in local survey work during the transitionary period of the early seventies. Curiously enough, they never were considered to be in need of a linear-engine refit. Instead, a shield generator upgrade and weapon system repositioning saw the vessels decommissioned between late 2271 and early 2278, after which the resulting subclass of improved defensive potency was released for operations. While the subclass name K’Kmarak might have been theoretical only, the vessels in fact achieved considerable public fame under this name. Charting of rimward space was resumed, with now fully Vulcan crews continuing the work of the T’Plana-Hath. The surveyors made numerous first contacts at a time when the Fleet’s exploration-capable heavy units were otherwise disposed.
All but six of the Vulcan and three of the Star Fleet vessels were idled by the mid-2280s due to the increasing Klingon threat. Ultimately, only USS Ratha (NAR-24309) was retained for ‘technology evaluation purposes’, carrying classified equipment whilst operating in the vicinity of Omega Leonis. The far larger and more heavily equipped Nineveh class took over frontier survey operations, often with armed escorts for protection.

Notes
- I've broken out the research staff from the crew, specifically because they were called out in the sidebar, but they should be considered permanent members of the complement. The specialist passengers are assigned temporarily, with the number presumed to be low.
- There will have to be some un-teasing of data: the T'Pari were the Vulcan science ships; the (original) Star Fleet ones would have their own sub-class name of Thuringia. In 2262-2264, these would be upgraded with additional FTL sensors. Sixteen of the original Vulcan Science Directorate's T'Paris would be upgraded to the K’Kmarak standard. There is a fair chance the article should be re-named to "Thuringia".
- Adrasil: maybe have VSD-colored ships as an addition to the SRM.
- The years of construction for the T'Paris and Thuringias are inferred; the Thuringias would be identical to the T'Paris and built concurrently (though not immediately so). The years of operation for the variants are also inferred. The six T'Paris not converted to K’Kmarak standard are presumed to have been decommissioned early in the conversion schedule. The K’Kmaraks were deemed to be decommissioned late in the 2280s because at least 6 were not decommissioned in the mid-2280s, while the USS Ratha was noted as one of the total 9 (in the series) to continue operating into 2291.
