SpaceX Receives Pentagon Help To Develop New Rocket Engine

SpaceX has been awarded a Pentagon contract for development of its next generation Raptor rocket engine, which is 6 times more powerful than the Merlin engine it uses now.

The U.S. Department of Defense has announced a $33.7 million dollar contract awarded to SpaceX for the development of the Raptor rocket propulsion system prototype as part of the Evolved Expendable Launch Vehicle (EELV) program. The Raptor engine burns a mixture of liquid methane and liquid oxygen, and designed to produce six times the thrust of the Merlin engines SpaceX recently used on its historic mission that saw its first stage rocket land itself back on earth from orbit. Here’s why that’s important to SpaceX.

Currently, virtually all large military satellites launches are done by the United Launch Alliance, a consortium made up of Lockheed Martin and Boeing. In 2013, ULA was awarded a $1.1 billion contract for multiple launches using Lockheed Martin’s Atlas V or Boeing’s Delta IV rockets. SpaceX wants a piece of that pie.

According to Motley Fool, both ULA rockets use RD-180 engines purchased from Russia’s Energomash, which is majority owned by the Russian government. After Russia’s 2014 actions in Crimea, the US slapped economic sanctions on it and Energomash. They in turn decided they would not sell any more rocket engines to ULA. The US Congress responded to that by prohibiting the US military from using any Russian rocket engines to launch its satellites.

But Houston, we have a problem. No rocket engines means no satellite launches. ULA placed its hopes on either Blue Origin or Aerojet Rocketdyne coming up with a new rocket engine to replace the RD-180 it can no longer buy from Energomash, but that process could take 3 or 4 years to complete.

So Congress has relented somewhat. Buried in the more than 1,000 page appropriations bill approved just before Christmas, it gave ULA approval to buy a supply of RD-180s — just enough to keep it in the military launch business for the time being. But clearly, America needs American made rockets for its various space programs going forward.

SpaceX-Falcon-Heavy

Enter SpaceX, which received authorization to bid for Pentagon business last year. The next generation Raptor engines will be used to power the upcoming Falcon 9 “heavy lift” and “super heavy lift” rockets. The more powerful Falcon 9 could be used in place of the traditional satellite launching vehicles from Lockheed and Boeing. That would open the door for lucrative government contracts to flow to SpaceX instead of ULA.

There is a lot of money up for grabs launching satellites for the military over next several years. SpaceX has been funding its Raptor engine program out of its own pocket up until now, but under terms of the new contract, the Pentagon will provide $1 in development funding for every $2 invested by SpaceX.

Lockheed and Boeing might be giving way to the Aerospace upstart. SpaceX, like every venture Elon Musk is involved with, will put every ounce of effort into getting to the finish line ahead of everyone else.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo

“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.

NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance. 

More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system. 

Jensen Huang’s praise for Tesla FSD

Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”

During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:

“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.

“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said. 

Nvidia’s platform approach vs Tesla’s integration

Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.

“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.

He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.

“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”

He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.

Elon Musk confirms xAI’s purchase of five 380 MW natural gas turbines

The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.

xAI, Elon Musk’s artificial intelligence startup, has purchased five additional 380 MW natural gas turbines from South Korea’s Doosan Enerbility to power its growing supercomputer clusters. 

The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.

xAI’s turbine deal details

News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.

As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X. 

xAI’s ambitions 

Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”

The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.

xAI’s core mission

Th Series E funding builds on xAI’s previous rounds, powering Grok advancements and massive compute expansions like the Memphis supercluster. The upsized demand reflects growing recognition of xAI’s potential in frontier AI.

xAI also highlighted several of its breakthroughs in 2025, from the buildout of Colossus I and II, which ended with over 1 million H100 GPU equivalents, and the rollout of the Grok 4 Series, Grok Voice, and Grok Imagine, among others. The company also confirmed that work is already underway to train the flagship large language model’s next iteration, Grok 5. 

“Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote.
