  "account": "Carlyle Group has joined JPMorgan Chase and Andreessen Horowitz in a $1.1 billion funding round for defence technology company Castelion, according to the Wall Street Journal. The California-based startup valued itself at approximately $13 billion following the Series C financing. The round includes about $800 million of equity and a $250 million revolving credit facility, with additional venture capital investors. Castelion intends to utilize the capital to expedite production of its Blackbeard hypersonic missile, develop a larger hypersonic strike system, and create a missile for mass-produced air defense. The investment comes as governments and defense departments focus on rebuilding munitions capacity and developing weapons to counter sophisticated military systems. The conflict in Ukraine has strained Western missile inventories, and the growing demand for air-defense systems has heightened concerns over available stockpiles. Carlyle sees an opportunity to invest in rebuilding defense manufacturing capacity that has diminished over the decades, particularly in areas like munitions and hypersonic weapons. JPMorgan's participation indicates the willingness of major financial institutions to provide capital to emerging defense companies. Castelion, founded by former SpaceX employees, aims to accelerate the design, testing, and manufacturing of military hardware compared to traditional contractors. The company has invested roughly $250 million in a manufacturing campus in New Mexico for Blackbeard production and plans to secure an additional site for future weapon systems. Management is also working on a longer-range hypersonic platform to meet US military requirements in the Pacific. The company opts to invest in development before securing a formal Pentagon contract, arguing that moving earlier in the process will enable faster production once demand arises.",
