- Activist investor Elliott Investment Management has taken a stake in Stratolaunch, a hypersonic-flight company that has conducted successful tests of a reusable hypersonic vehicle for the U.S. military, the Wall Street Journal reported on Monday.

Elliott will also gain board representation at privately held Stratolaunch, and its investment is worth several hundred million dollars, the Journal said, citing people familiar with the matter. The WSJ report added that the exact size was not known.

Reuters could not immediately verify the WSJ report. Elliott and Stratolaunch did not immediately respond to a Reuters request for comment.

Last May, the Pentagon said Stratolaunch was part of a second successful test of a reusable hypersonic test vehicle , following an earlier test of its Talon-A vehicle in December 2024 that was not publicized.

Unlike single-use rockets, the reusable Talon-A can be rapidly turned around and flown again at lower cost, accelerating U.S. development of hypersonic weapons that operate at more than five times the speed of sound, or about 6,200 km (3,852.5 miles) per hour.

The vehicle will be used to carry hypersonic weapons systems during their development.
