SpaceX to launch five South Korean military satellites by 2025

Published

South Korea is deepening its relationship with SpaceX with a contract to launch at least five military reconnaissance satellites on Falcon 9 rockets by the end of 2025.

Known as the “425 Project,” South Korea intends to operate its own small constellation of five new Earth observation satellites: four synthetic aperture radar (SAR) satellites and one electro-optical infrared (EO/IR) satellite. All five would help ensure the near-continuous observation of sites of interest in North Korea, nominally allowing for new observations to be made at least every two hours. In a boon to South Korea’s aerospace industry, the country intends to domestically design and manufacture most or all aspects of those spacecraft. Developing domestic aerospace solutions has been a significant industrial priority for the country in recent years.

As a result, South Korea’s first stab at a domestic satellite constellation probably won’t produce record-breaking results. Publicly, the goal is to develop satellites with a maximum resolution of 0.3-0.5 meters (1-1.6 ft) per pixel – similar to the publicly established capabilities of most modern mid-sized Earth observation satellites. However, the classified capabilities of the US military and US spy agencies may offer several times that resolving power. South Korea is a close ally of the United States and likely benefits significantly from shared US intelligence. But it’s still no surprise that a country with such a belligerent neighbor would want to own and operate its own fleet of reconnaissance satellites and have the ability to independently produce its own spacecraft.

On top of working on those spacecraft, South Korea has also been developing a fully domestic orbital launch capability. The Korea Aerospace Research Institute (KARI) attempted to launch the first fully completed Korean Satellite Launch Vehicle II (KSLV-2) – also known as Nuri – in October 2021 but fell just short of orbit after its first and second stages performed nominally but its third stage ran into pressurization issues. Nuri is scheduled to return to flight as early as June 15th, 2022. Once operational, the South Korean rocket is designed to launch up to 2.6 tons (~5700 lb) to low Earth orbit (LEO) and 1.5 tons (~3300 lb) to a slightly higher sun-synchronous orbit (SSO).

South Korea’s decision to manifest its 425 Project satellites on SpaceX rockets thus raises some questions about South Korea’s confidence in – or plans to use – its own homegrown launch capabilities. Assuming Nuri more or less meets its performance goals and successfully reaches orbit during its second launch attempt in mid-2022, both of which seem plausible, the rocket would likely be more than capable of beginning operational launches no later than 2023. In fact, South Korea says that its EO/IR satellite – scheduled to launch first – will weigh around 800 kilograms (~1750 lb), making it a near-perfect fit for Nuri’s first operational launch. Such a small payload would give the rocket a large safety margin to account for any unexpected performance losses.

Instead, South Korea has decided to launch all five spacecraft on SpaceX rockets. SpaceX already has a solid relationship with the country: the company recently launched its Lockheed Martin-built ANASIS-II military communications satellite and is scheduled to launch KARI’s Korean Pathfinder Lunar Orbiter (KPLO) – South Korea’s first mission beyond Earth orbit – no earlier than August 2022.

It’s unclear if SpaceX will launch South Korea’s ‘425’ satellites individually on dedicated Falcon 9s, as rideshare payloads alongside other paying customers, or – in the case of the four SAR satellites – in batches of two or four. KPLO will be a Falcon 9 rideshare payload, making it clear that South Korea is happy to exploit cost-effective rideshare launches – though that calculus may change for military payloads. Regardless, South Korea’s latest contract won’t hurt SpaceX’s commercial manifest, which currently includes around 75 publicly-acknowledged Falcon launches.

Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk. 

The Tesla CEO shared his recent insights in a post on social media platform X.

Musk details AI chip roadmap

In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle. 

He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.

Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.

AI5 manufacturing takes shape

Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.

Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.

Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.

According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.

The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring. 

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.

The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.  

ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.

“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.

“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade

Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.

Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.

Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.

Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error. 

More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report. 

Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.

Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.

Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.

“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
