Startup with hypersonic weapons Castelion According to the sources and documents viewed by TechCrunch, it collects $ 350 million of series B under the leadership of LightSpeed Venture Partners and Altimeter Capital.
It is expected that the round, which values the company in billions, will likely be closed inside a few weeks. A term sheet was signed. The recent round comes from $ 100 million heels in financing the A series, which closed in January. This round consisted of about 70 million dollars of capital and $ 30 million in debt. Lightspeed also led this round.
Castelion refused to comment.
Non -traditional players are extremely difficult to interrupt into the large government defense market, but Castelion has made significant progress since she emerged from Stealth at the end of 2023. The company that was founded by former SpaceX managers wants to rework the production of hyperonic rocket systems, critical national security technology.
Despite the huge budget of the US Department of Defense, military leaders sound an alarm regarding China’s ability to quickly develop and hyperpersons. This weapon travels over Mach 5 – and China’s capabilities begin to overtake the United States.
Castelion proposes a solution. The company has a similar approach to SpaceX: build quickly, often test and integrate vertically to cut back costs. Subsidies and awards from the DUP package have already won, including the Air Force Research Laboratory and the Air Systems Command. The company for the first time tested its hypersonic vehicle in the Mojave desert in March, because it desires to prove to the government that it will possibly show low cost large -scale hypersonic shells.
Castelion appeared in the tax yr of the American Army 2026 A request for the budget Posted in June. In the budget, the Military Branch demanded $ 25 million as part of the initiative called Project HX3 to support the development and testing of “inexpensive, mass -produced hypkersonic weapons” called Blackbeard Ground Launch (GL). As the document explains, Blackbeard GL will have about 80% of the ability of the distance distance of the hypersonic weapons of long -range weapons currently developed by the Aerospace Prime. But on the basis of a contract, the army claims that it is ready to exchange some speed and range for a cheaper product.
The upcoming contract, which is principally concluded, when President Trump signs the budget, has two phases: the first will see that Castelion will provide “prototype proof of concept”, which is able to display at the starting of 2026, if this is successful, the second phase will include the delivery of 10 prototype missiles in 2027 for additional testing using a standard start platform artillery. Blackbeard is also designed to be compatible with a recent programming system that can have autonomous possibilities.
All previous Castelion wins with Dod are Pittanka in comparison with the possibilities provided by the lucrative market for hypersonic weapons. If the tests in the army’s case go well, Castelion can save a larger contract and start delivering Blackbeard shells at the starting of 2028.
Lockheed Martin, Raytheon and Northrop Grumman will probably want to watch their back.
