# The Feasibility of Launching Satellites With a Giant Space Gun Exploring the unconventional idea of using massive artillery for orbital payload delivery - **Source:** [CNET (YouTube)](https://brifing.si/source/d98fed98-60b0-44b1-9469-4438fc7d13f9) - **Published:** 2026-09-06 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/732f6434-af8a-4e8a-a028-befb3b792c7e ## The radical concept The idea of using a giant gun to launch satellites dates back to Jules Verne's 1865 novel. Modern versions propose electromagnetic railguns or light gas guns to accelerate payloads to orbital velocities. This method could theoretically reduce launch costs by eliminating rocket fuel needs. Several startups are currently exploring variations of this technology. ## Physics challenges Payloads would experience extreme g-forces (potentially 10,000g) during launch, limiting what could be sent. Delicate electronics would need special hardening. The gun would require an enormous barrel length (kilometers long) to gradually accelerate payloads. Atmospheric drag at lower altitudes presents another significant engineering hurdle. ## Historical attempts Project HARP in the 1960s tested space guns, achieving 180km altitude. Iraq's Babylon supergun project was stopped in 1990. Gerald Bull, the scientist behind these projects, was assassinated under mysterious circumstances. These attempts proved the concept's viability but highlighted political and technical challenges. ## Energy requirements A space gun would need massive power infrastructure - equivalent to small nuclear plants. Electromagnetic versions would require capacitor banks storing gigajoules of energy. The acceleration process would generate tremendous heat, requiring advanced cooling systems. Energy costs might offset fuel savings. ## Payload limitations Current concepts could only launch small, rugged payloads under 100kg. No human-rated version is feasible due to g-forces. The technology suits cube satellites and durable military payloads. Complex orbital maneuvers would require secondary propulsion systems. ## Environmental impact Space guns would produce significant noise pollution and require remote locations. The launch process might affect local wildlife. Unlike rockets, they wouldn't emit greenhouse gases during operation. However, construction would have substantial ecological footprint. ## Economic considerations Development costs could exceed $1 billion before operational use. Maintenance of the massive infrastructure would be expensive. Potential savings come from reusable launch systems versus disposable guns. The business case depends on achieving very high launch frequencies. ## Future potential Space guns could complement traditional rockets for specific payload types. They may find niche applications in rapid military deployment or bulk material launches. As materials science advances, more payload types might become viable. The concept remains an intriguing alternative in the New Space race. ## Sources covering this story - https://www.youtube.com/watch?v=ge4ZHXMBsuk — --- _Summary written by Brifing from the original reporting.
