Starting of ultrasonic weapons Vestibule It increases a series of $ 350 million B, led by Lightspeed Venture Partners and Altimeter Capital, according to sources and documents considered by Techcrunch.
The round, which values the company in the billions, is expected to close in a few weeks. A sheet of terms has been signed. The new round comes in heels of $ 100 million in a series of A series that ended in January. This round consists of about $ 70 million in shares and debt of $ 30 million. Lightspeed also drove this round.
Castelion refused to comment.
It is well known that non -traditional players will enter the remarkable government defense market, but Castelion has taken remarkable steps since it came from Stealth at the end of 2023.
Despite the huge budget of the US Department of Defense, military leaders are hearing the alarm about China’s ability to grow quickly and achieve the remains. These weapons travel over Mach 5 – and China’s capabilities begin to overcome the United States.
Castelion suggests a solution. The business adopts a similar approach to Spacex: Build quickly, try frequently and vertically integrated to reduce costs. He has already won grants and awards from a DOD offices suite, including the Air Force Research Laboratory and Naval Air Systems. The company examined its ultrasound vehicle for the first time in the Mojave Desert in March, as it seems to prove the government that it can destroy low -cost ultrasonic missiles.
Castelion appeared in the financial year of the US Army Army 2026 budget request Published in June. In the budget, the military branch requested $ 25 million based on an initiative called HX3 project to support the development and testing of an “affordable, massive ultrasound production” called Blackbeard Ground Launch (GL). As the document explains, the Blackbeard GL will have about 80% of the capacity of a long -range ultrasound variant that is currently developed by Aerospace Primes. But through the contract, the army says they are willing to exchange a little speed and reach a lower cost product.
The upcoming contract, which is essentially a comprehensive agreement when President Trump sign the law budget, has two phases: the first will see Castelion deliver an “original proof of the information” which will demonstrate in early 2026. Blackbeard is also designed to be compatible with a new system.
All of Castelion’s previous victories with DOD are a bitterness compared to the capabilities offered by the lucrative market weapons. If the army’s field tests are going well, Castelion could stay on a larger contract and start delivering Blackbeard missiles in early 2028.
Lockheed Martin, Raytheon and Northrop Grumman may want to watch their backs.
