So what are the most beautiful sci-fi starships, according to your taste?

Here are mine:

Imperator-Class Star Destroyer (Star Wars)

There are many reasons why I love Star Wars, and Star Destroyer is one of them.

Executor-Class Command Ship (Star Wars)

If there's anything more beautiful than a Star Destroyer, then an Executor-Class Command Ship definitely is. It shares the triangular, dagger-shape of Star Destroyer, but has more slender look --which perfectly fits its size.

Romulan Warbird (Star Trek)

I always thought Star Trek ships are ugly. That is, until the first time I saw a Romulan Warbird --it's beautiful!

Chmmr Avatar (Star Control 2)

This Chmmr Avatar is probably the most powerful starship in Star Control 2 PC game. It wields a laser so dangerous when fired, it ionizes the solar wind. Orbiting around the Avatar are three ZapSats - sturdy satellites that automatically fire their own laser weapons at incoming ship and missiles. Take a look --it's good-looking!

Manchi Vulture (Space Rogue)

I always thought that the triangular, dagger-shaped KDY warships of Star Wars universe are the most beautiful. However, this one is an exception: the Manchi Vulture from Space Rogue PC game definitely looks better than Star Destroyer and Executor.

The pic below is taken from the game manual, by the way.
