Stratolaunch's Roc, the world's largest aircraft, has entered a partnership with Kratos Defense to advance its applications for hypersonic flight testing and defense systems. With a wingspan of 385 feet and a maximum takeoff weight of 1.3 million pounds, Roc is designed to launch hypersonic test vehicles like the Talon-A, a Mach 5-capable system from Kratos.

This collaboration aims to provide a cost-effective alternative to traditional rocket launches, facilitating frequent testing in near-space conditions. The partnership aligns with the U.S. military's increasing demand for hypersonic capabilities, as geopolitical tensions drive interest in advanced aerospace technologies.

Key test missions are set for 2024, with commercial applications expected by 2025. Challenges remain in proving the reliability and safety of the Roc for multiple missions and integrating Kratos' systems before potential government contracts can be secured.
