Prescience-class Stellar Science Vessel

The Prescience-class was a new generation of science vessels designed for short to medium term stellar exploration. At a length of 225 meters, the ship's typical crew complement was 60 and it had a total of 72 living quarters (68 standard quarters, 4 executive quarters). The Prescience had a maximum speed of warp 9.4 and a cruise speed of warp 8.
Unlike typical Starfleet design of its time, the Precience's saucer section was ring shaped. This way the design required less materials and still provided ample space for living quarters and laboratories. Originally a smaller, more spherical saucer was proposed, but it quickly became obvious that the extensive sensor equipment, which now occupies the forward quarter of the ring, could not be fitted onto a smaller saucer.
Also unlike typical Starfleet design, the engineering section is part of the saucer, sitting atop the secondary hull. The secondary hull, in turn, houses the navigational deflector and shuttle bay.
While the Prescience was not designed with combat in mind, it is capable of holding its own, sporting a total of 7 phaser strips, 4 on the saucer and 3 on the secondary hull.
To minimize damage to subspace caused by warp travel, the Prescience's warp nacelles are mounted on adjustable hinges. During impulse flight the nacelles will typically be angled up slightly. When at warp speed the nacelles will initially rotate down and then constantly change their angle to adjust the warp field's geometry to fit current subspace conditions. This way the ship will slip through subspace rather than cleaving through it as earlier ships did, significantly reducing subspace wear.

This ship took me a long time. It was primarily inspired by a concept draft I once saw, and a ring-shaped ship from ST: Discovery. Most extensive surface modelling I've ever done, although a lot of it is rather subtle and only visible from close up.
