System development is also largely complete as hydraulics, electrics and basic weapon systems are operational and we’ll continue to fine tune them as tests proceed. The AN/ARC-5 Radio and navigation equipment were also completed and tested earlier this spring. Decision to add the AN/ARC-1 radio set is still pending. Smaller things such as the oxygen equipment, anti-blackout suit, and particularly interesting (based on carbon-dioxide), the emergency landing gear extension system remain, due to the cockpit enhancements.
