As far as we understand physics today, we won't ever be able to get to the speed of light. The faster you go, the harder it gets to go any faster. So that last little fraction will "always" remain impossible - or at least until someone invents a whole new branch of physics.
So the only ships that can reach the speed of light are the ones in our imagination.

How does a ship use light speed?
Nothing except electromagnetic radiation uses light speed.
Do the electrons move the speed of the light?
No, because the orbital is really just an abraction - the electron isn't racing around the orbital like a racecar, so there isn't a speed. The orbital is a better measure of the electrons potential energy.
Which vehicles can reach to the speed of light?
None can.
How does sunlight reach earth?
the light speed are very fast so light easily reach on earth
The upper limit to the speed of an object with mass?
An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.An object with mass might approach, but never reach, the speed of light.
Does mass travel at the speed of light or does it vibrate at the speed of light?
Neither, mass can never reach the speed of light, this question also contridicts the theory of realativity.
How To Travel At The Speed Of Light?
You can't travel at the speed of light. It might be possible, in theory, to approach it, but not quite to reach it.
Would a man or anything survive inside a space ship traveling the speed of light?
According to our understanding of physics (which is always subject to revision and reinterpretation as we learn more) it is impossible to travel AT the speed of light. A spacecraft with sufficient power can go very CLOSE to the speed of light (although because of the interstellar gas and dust, it would probably be quite dangerous to do so!) but can never actually REACH the speed of light.
If a space vehicle of unknown mass with an infinite amount of fuel had a 1 pound thrust engine running continuously would it eventually reach the speed of light?
It would never reach the speed of light because things with mass can't move at the speed of light. However, it would eventually get as close to the speed of light as you want.
Why traveling at the speed of light would we disperse?
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
Can a light year ship be invented?
Do you mean a light SPEED ship? Ignoring the possiblity of "warp" technology, which, though potentially faster than light, does not really address the problem of achieving light speed, but circumvents it: As speed increases, so does mass. The increase in mass is imperceptible at the speeds you and I commonly travel, and even at the enormous speeds (but still nowhere near light-speed) achieved by the space shuttle. However, at speeds near light speed, mass increases assymptotically. At light speed, mass is, in fact, infinite. If a ship was attempting to attain light speed, its mass would increase more and more with each additional unit of speed. As it gets closer to light speed, the mass would be so great that no amount of thrust would be able to get it TO light-speed. The mathematical proof of this is somewhat more complicated, but take my word for it - it's impossible.
