Castelion, a hypersonic missile startup founded by former SpaceX executives, has raised $1 billion to produce low-cost hypersonic weapons and expand its portfolio of strike and missile defense systems. The company aims to develop a range of longer-range strike and missile defense weapons. This investment will help Castelion advance its technology and production capabilities.
The development of hypersonic missiles has significant implications for national security, as these weapons can travel at speeds over Mach 5 and evade traditional defense systems. Castelion's low-cost approach could make hypersonic technology more accessible to militaries and challenge existing defense strategies.
