Death Star and its successor, Starkiller Base ('Star Wars' franchise)
The Death Star and successor Starkiller Base are pure cool, but they're a few ranks behind the Millennium Falcon because well, people keep finding ways to destroy them. But let's ignore that and focus on the positives. First of all is the pure power — the Death Star can easily kill a single planet, while the Starkiller Base can wipe out entire planetary systems. They also have a bit of a stealth aspect, despite being so big; one famous line compares the Death Star to a moon, at least because it's so huge and has a crater on it. And let's not forget that Starkiller Base somehow broke the laws of physics and got its power from "quintessence," a sort of dark energy that is everywhere in the universe.

Ha'tak ('Stargate' franchise)
Ha'tak looks like a lumbering pyramid in space, but even a newbie to the Stargate universe can see it's a powerful force to be reckoned with. The Stargate fan wiki notes that Ha'taks use an advanced form of propulsion that allow the ship to get as fast as 5 percent of lightspeed. Its shields are so powerful that they can hold off the heat of the corona — the atmosphere — of a huge star for many hours. Some Ha'taks even include cloaking devices, although that's not standard issue in the fleet. It sure was enough of a threat to worry the humans in the Stargate program, however.

Event Horizon ship (1997)
In terms of pure terrifying innovation, it's hard to beat the after-effects of the Event Horizon. As recounted in the eponymous 1997 film, a crew of astronauts from the future set out on a rescue mission. They're after the Event Horizon, which had suddenly appeared in orbit around Neptune. The crew boards the ship in search of any of their missing crewmates.
Unfortunately, they find out that Event Horizon's experimental engine caused a few problems — namely, it ripped a hole in space-time and a nasty homicidal alien was on board the ship. While we (unfortunately) don't get to see the ship at full health during this terrifying movie, we do learn it's capable of generating black holes. Talk about power.
NEXT: An enormous structure
'Independence Day' mothership (1996)
Hovering ominously over Earth in the original 'Independence Day,' this ship is huge — some 600 kilometers (roughly 370 miles) long. As viewers saw in the film, there are a bunch of tunnels that lead to the inside of the ship; two brave crew members from Earth managed to make their way into the control center, where they saw an eerie blue mist surrounding the zone. The Independence Day wiki also mentions a "beehive-like structure" that serves as the ship's transportation center. Little is known about this ship's capabilities, but it's downright scary.
NEXT: A streamlined beauty
USCSS Prometheus ('Prometheus,' 2012)
This black beauty is the most advanced and expensive faster-than-light ship ever made, according to the "Alien vs. Predator" wiki. It's got all the comforts you'd expect for a spaceship going long distances — a hypersleep chamber, a series of on-board ATVs for planetary exploration, escape modules and even intergalactic communications antennas. It even — improbably, for its size — can do vertical takeoffs and landings, which makes it ideal for landing on a planet. Well, that's if the planet doesn't have homicidal aliens living there already.
NEXT: A comfortable steed
The Rocinante ('The Expanse' franchise)
The Rocinante is a comfortable, yet fast warship — the designers even took into account the preference for humans to have g-forces similar to normal gravity (at least, while the ship is under thrust). It's a pretty awesome workhorse ship, in that it can fire torpedoes or help with boarding parties. Besides which, it goes fast through space. Perfect for dodging any incoming missiles.

Heart of Gold ('Hitchhiker's Guide to the Galaxy' franchise)
This is a fun, zippy ship, thanks to its unique use of the Infinite Improbability Drive — an engine that provides for near-instantaneous travel with "tedious mucking about in hyperspace," according to the Hitchhiker's fan wiki. The designers gave a lot of attention to creature comforts, even including doors who say (in the books) how glad they are to help you. While the shape of the ship varies between the book, movie and TV series, a common theme in all three media is how white and clean the ship looks.
NEXT: A cry of desparation
Icarus II ('Sunshine,' 2007)
We love this spaceship because it shows just what humans can do if they are desperate enough. Basically, Earth is in crisis because the sun's power is fading a lot earlier than expected (in the year 2057, to be precise.) The point of Icarus II is to carry a huge nuclear bomb towards the sun. The crew faces many problems and saboteurs along the way, but somehow this ship just keeps on running — mostly as it's supposed to. That makes it worthy of a mention.
NEXT: A compact marvel
Superman/Kal-El spaceship ('Superman' franchise)
We're more intrigued by Superman's spaceship than able to say much about it, but that said, there are some cool unanswered questions to consider when thinking about Superman was shipped to Earth. Kal-El, as the infant was called, somehow stayed in a small space and was fed, cleaned, kept warm and kept entertained on his trip to Earth. That's some mean sort of automation. Also, the ship was relatively small — where did all of these systems fit? Goes to show you that planet Krypton residents were really smart.
NEXT: A vibrant forest
The Valley Forge ('Silent Running,' 1972)
We applaud the constructors of the Valley Forge for somehow figuring out how to build a closed ecosystem. Inside of this (somewhat large) spaceship is a forest filled with animal and plant life, tenderly cared for because Earth's planet life has somehow gone extinct; this ecosystem should give our planet a kick-start, once the time is right. There's a flaw with this forest, though, in that it needs a source of light to survive. This ends up being crucial to the plot. Alas, the forest is shown drifting into deep space at the end of the film, so it's not clear how the lights will be generated once the ship's power source runs out.
