Navy Engineers Unleash Long-Range Tech at Twentynine Palms

In May 2025, Naval Research Laboratory engineers tested the advanced RASP CASA system (Refueling and Servicing Package for Communications and Situational Awareness) at Twentynine Palms, California, showcasing how hydrogen-powered technologies can extend warfighter capabilities. The demonstration featured high-altitude balloons and long-endurance unmanned aircraft using hydrogen fuel cells to enable over-the-horizon communications, real-time video, and command links—well beyond traditional line-of-sight limits. This breakthrough not only enhances situational awareness for Marines and Sailors but also offers low-signature power solutions and the ability to produce hydrogen locally, giving the military major logistical and operational advantages. Looking ahead, the Navy aims to take this tech shipboard, launching autonomous aircraft and balloons directly from vessels at sea to revolutionize battlefield communications and endurance.
