We are not building a ship that can go .9+
c in a hurry. Also it needs to be a speed greater than .9
c because this effect dosn't become useful for interstellar travel until a speed of around .999
c is reached.
(FWI: for those who don't know
c = the speed of light in a vacuum.)
Building such a ship would be a massive endeavor both in terms of building the ship and R&D. The drive would need to be some kind of Fusion drive (Like the "Impulse Engines" in Star Trek) or a massive Antimatter Boosted Fusion Orion drive (Super H-Bombs injected with Antimatter). Both would require a huge investment in R&D and infrastructure (especially for Anti-matter production) to be developed.
