Clarke class destroyer, the first Jovian fusion destroyer, this ship's completion marked the formation of Jovian Spaceborn Armed Forces and was the first dedicated warship of allied Jovian moons. It was introduced into service in the late stages of war with Martians, and until that point the only spaceborn resistance the Jovians could provide was with improvised warships made from converting civilian nuclear, and even chemical rocket ships. While those did provide some nuisance to the invaders, in the end, they just didn't have the range and capability to prevent Martians from dictating battlefield conditions. Worse still, even in large numbers, they where no match to Martian destroyers, only barely managing to take down a single destroyer at the very beginning of the conflict. That early victory was paid with great sacrifice, and while Martians wouldn't allow for such a situation to happen ever again, the Jovians did manage to recover the downed destroyer's fusion engine.

With Saturnian assistance the engine was reverse engineered, boosting Saturnian progress with fusion engines on their side, and paving the way for Clarke class destroyers for Jovians. Fusion engine was the main focus, and at the same time other parts of the ship where built on separate locations, awaiting the final assembly. Side mounted nuclear rocket engines where added for redundancy, in case of main engine failure, and to provide additional thrust if needed in combat. The head piece is practically the only pressurized part of the ship, and was made to be detachable, so it's a ship on its own, with very limited range range. Bellow head, all the major components where connected with heavy reliance on struts, decreasing the ships durability, but also lowering its overall mass. Sensor masts, EM cannons and external cargo holds where added after the struts, completing the ship at last.

As a warship it was plagued with many issues, most coming from the improvised and rushed way it was built, some of which where improved on by subsequent ships of the same class, and some with practiced use. Its long range weapons where limited by subpar sensors, but where very potent if other ships provided sensor data. Crew accommodations where very cramped, and only minor simulation of gravity was provided by deployable centrifuge. The worst flaw was its poor anti missile defense, with EM cannon providing point defense, and heavy reliance on decoy flares, the ship wasn't able to defend properly from long range missile attacks, forcing a configuration in which several of its long range anti ship missiles would be traded in for area defense missiles.

Even with all the optimizations, Clarke class was simply no match for Martian Lothbrok class destroyers, and several of her class where lost while proving the fact. The real advantage they provided was their long range interplanetary capability. With it the Jovians where no longer forced to remain on the defense, and Martians had to rearrange their formations to compensate, opening weak spots to be exploited. With the increasing resources the war was draining from Martians, and power shifts on other fronts, they where forced to pull back their occupation force, and eventually sign a peace treaty.

Nowadays newer and much more capable Wells class destroyers have taken the frontline position, while those of Clarke class that remained operational where relegated to shorter range patrols and anti pirate duties.

Cool design! All the details seem spot on.
The only thing I'd question is that perhaps the communication antenna pair placement could be rotated 45 degrees around the ship's long axis so they are not blocked by the side engines to the rear. But that's minor.

I was mainly concerned with antennas having a clear path in all direction, with the radiator wing going strait between them ( stash ). Wasn't really considering how much the engine exhaust could cover up their reception. I liked this position on the mast since they can easily rotate in most directions and track whatever the ship needs tracking. It could be a nice addition to add some more antennas on the back of the big spherical fuel tank, at 45 degrees to the ship's long axis, which would also give it some more eyes on the back, good for a warship.

And thank you! A praise from you means a lot!

Hmm.  This looks plausible, say circa 2075-2100.  I can imagine a ship might actually look something like that, at that point in the future.  Cool render!

I think the main implausible part is that the fusion engine is probably too small, unless it was made from some handwavium materials, but hey, that's why it's only a sort of realistic spaceship. But in case you're wondering, the background story would place it somewhere around year 2200, though after some apocalyptic event in the late 21. century that slowed down technological progress.

And thank you, I'm also very happy with how it turned out, and plan to use this ship in some upcoming renders
