Pulsar Fusion, a rising force in UK aerospace engineering, is pushing humanity into a new era of deep-space travel with its revolutionary SUNBIRD fusion rocket. Designed around a Direct Fusion Drive (DFD), Sunbird draws power from the same fundamental process that fuels the Sun — controlled fusion — offering clean, efficient, ultra-high-energy propulsion.
Unlike chemical rockets that burn fuel explosively, Sunbird uses fusion reactions to generate massive thrust with minimal waste. This makes it one of the most promising next-generation engines ever proposed.
Sunbird’s theoretical top speed is an astounding 329,000 mph. This velocity represents a giant leap forward, surpassing current spacecraft propulsion capabilities by orders of magnitude.
If successful, Sunbird will fundamentally rewrite mission timelines:
This technology accelerates:
Despite its unprecedented capabilities, Sunbird is designed for reuse and cost-effectiveness. Each rocket is projected to cost approximately $70 million, placing it in a competitive position against both chemical and nuclear propulsion systems.
The fusion-based design produces minimal waste and eliminates reliance on combustion fuels completely.
Pulsar Fusion plans to begin orbital testing of the Sunbird vehicle by 2027, marking what could become humanity’s first real step into the fusion-powered space age.
For decades fusion propulsion existed only in theory, fiction, and laboratory concepts. Sunbird is the first credible engineering leap toward real fusion spacecraft.
If the project succeeds, the implications will include:
