UK nuclear fusion gun startup pivots to space tech after ditching reactor plans

First Light Fusion, a UK startup, has shifted focus from developing a nuclear fusion reactor to commercializing its "Big Friendly Gun" technology for defense and space applications. This pivot aims to generate revenue quickly, creating a "capital-light, high-margin business." First Light will collaborate with fusion firms, universities, and organizations like NASA to explore uses for its amplifier technology, which outperforms existing gas guns in pressure levels and speed.
