We recently marked a historic milestone with the christening of the USX-1 Defiant in Everett, Washington. The Defiant is the first vessel of its kind designed from the keel up to never accommodate a human aboard.
This moment represents the culmination of years of hard work by a dedicated team determined to push the boundaries of what’s possible at sea.
Now, Defiant is moving into at-sea testing, the next step in its journey to redefine naval operations.
Stay tuned as we follow Defiant’s progress on the open water.

Bonded single crystal thin film multi-functional materials (electro-optic, acousto-electric, acousto-optic, magneto-optic or multi-ferroic materials) are vital for diverse sensing and communications technologies (integrated quantum, photonic, terahertz [THz], radio frequency [RF], and actuator platforms).
Wafer bonding onto compatible substrates is the critical step for integrating single crystal thin films into multi-functional devices and systems. There is currently no method to analytically investigate wafer bonding processes.
The ability to predictively model wafer bonding of thin film crystals would rapidly accelerate the research and development of multi-functional materials, and their fabrication and scalable integration in diverse applications.
This ARC Opportunity is soliciting ideas to explore the following question: To accelerate development and integration of multi-functional materials, how do we create generalizable models to explore thin film crystal bonding onto suitable substrates under diverse real-world process conditions and parameters?
