Castelion Strengthens Government Affairs Capability With Senior Defense Hire

According to a recent LinkedIn post from Castelion, the company is highlighting the addition of Cassie Miller as Senior Manager of Government Affairs. The post emphasizes her national security background spanning battlefield operations, the Pentagon, Capitol Hill, and most recently the Missile Defense Agency, a U.S. research, development, and acquisition body.

The post also notes Miller’s prior role as the U.S. Army’s principal congressional liaison for hypersonics, air and missile defense, and her 15-plus years of Army service defending U.S. forces from rocket and missile attacks. This profile suggests Castelion is deepening its government affairs and defense procurement expertise at a time when it is aiming to scale production of hypersonic systems.

From an investor perspective, the hire implies a strategic focus on strengthening relationships with U.S. defense agencies and Congress, which could be important for winning and expanding long-cycle government contracts. The emphasis on hypersonic systems and deterrence capabilities may position Castelion to benefit from sustained U.S. defense spending priorities in advanced missile and counter-missile technologies.
