A Stena RoRo vessel has reportedly been bought by Amazon billionaire Jeff Bezos' space exploration company Blue Origin.

WP Tech reported that the 2,175-lane-metre Stena Freighter (built 2004) will be used to ship rocket parts.

Most speculation in recent years relating to Bezos and shipping has surrounded Amazon's possible purchase of a containership fleet.

Blue Origin was set up in 2000 by Bezos to enable private access to space travel.
