SpaceXAI is preparing two additional data center campuses in Southaven, Mississippi, as Elon Musk sets out a year-end expansion target for its Colossus 2 artificial intelligence computing complex, according to Data Centre Dynamics.
The sites, called Gun Range and Spam, are intended to house approximately 420,000 Nvidia GB300 graphics processing units between them, Musk said in an X post reported by the publication on Monday. He said Gun Range was tracking to become operational by the end of November and Spam in December.
Those dates and GPU counts are Musk’s stated plans, not confirmation that the campuses or their full computing capacity are online. His broader target is about 1.2 million Blackwell GPUs deployed at Colossus 2 by the end of 2026.
Two sites, different computing roles
Gun Range takes its name from a former police and fire training center. DCD reported that the project will include two single-story buildings on a 55.9-acre parcel and is intended for a high-performance AI training cluster.
Spam is a former warehouse used to store products made by Hormel Foods, the maker of Spam. The plan calls for repurposing a single-story building on 53 acres for a data center optimized for inference, according to DCD.
The distinction separates the planned training cluster from the site intended to run models in use. The report did not establish how many of the planned GPUs have been installed, powered or made available to customers.
“Gun Range is tracking to be operational by end of November and Spam in December,” Musk wrote, according to DCD. He said he had walked the Colossus 2 site around midnight and again that morning, praising progress by the SpaceX team and contractors.
A larger Mississippi buildout
The two campuses would join Colossus 2 locations known as Macrohard, Macroharder and Minihard. DCD reported planned counts of 330,000, 220,000 and 220,000 GPUs for those locations, respectively. These are site-level deployment plans, rather than an independently verified count of usable computing capacity.
The expansion extends a data center portfolio that began in Memphis, Tennessee, across the state line into Mississippi. DCD reported that the original Colossus supercomputer launched in 2024 at a former Electrolux factory in Memphis’s Boxtown district. The company uses its data centers for its Grok AI chatbot.
Construction and power supply remain part of the wider story. DCD reported that Mississippi environmental regulators issued a notice last month alleging that construction activities at sites had begun before coverage under the state’s large-construction stormwater permit. The publication also described a separate NAACP lawsuit alleging that a gas-fired power plant in Southaven was built and operated without required permits. Those are allegations, not findings of liability.
For the new campuses, the next test is whether the announced construction schedules translate into operating facilities. Musk’s November, December and year-end targets describe an intended pace of expansion; they do not settle the timing of full GPU deployment or the capacity that will ultimately be available.
