JSF Fuel Tests Rev Up: Lockheed Martin has begun testing of the F-35 Joint Strike Fighter’s fuel system components, recently completing a “leak-free” fuel system checkout. Engineers and testers finished an extensive fuel system checkout on the first JSF and started a series of structural tests March 24. Company officials say that fuel leaks are typical for high performance fighter aircraft and believe the recent tests provide an “early indication the F-35 is a solid design.”
While the Space Force is still making long-term plans to establish high-fidelity live and virtual test and training ranges in the coming years, officials say they're also working with operators to identify near-term gaps and quickly field capabilities to address them.
