Apex, the world’s first spacecraft manufacturer to offer productized, high-rate configurable satellite bus platforms, announced Comet, the largest satellite bus in its product line. Comet, with a unique flat design, meets the needs of commercial customers launching high-power LEO missions, including Direct-to-Device constellations, as well as government customers requiring large aperture payloads.
Comet delivers more than 5 kilowatts of continuous power to payloads while its compact design allows it to stack flat in a launch vehicle’s 5-meter fairing. This form factor allows more satellites to fit on a single rocket launch, reducing costs. Engineered specifically to meet rigorous technical requirements at an economically viable price point, Comet optimizes capital expenditure for organizations deploying satellite networks at scale. Comet is specially designed to support advanced antenna systems that enable large networks of satellites, serving both commercial and national security needs.
“Apex developed Comet to enable a variety of commercial capabilities and defense missions,” said Ian Cinnamon, CEO of Apex. “From cell phone towers in space for consumer technology, unique sensing missions, or as an interceptor platform for Golden Dome, Comet is the clear choice to accelerate the most ambitious space missions.”

Apex’s differentiated approach to satellite bus productization has created a strong underlying foundation for the business. The introduction of Comet bolsters the company’s growing product line, including Aries, which celebrated one year on-orbit in March 2025. Apex also announced Nova in 2024, an ESPA-Grande satellite bus platform built to support 300kg of payload for mixed-use constellation customers. As the sole producer of truly productized satellite buses, Apex is committed to helping customers get to space faster and will continue to scale production to achieve that goal. Earlier this year, Apex also announced a $200 million financing round led by Point72 Ventures and 8VC to increase production to meet customer demand.
