• The US Navy is seeking a five-year engineering support contract for F-35 mission planning software redesign.
• The redesign aims to improve the ground-based system used by pilots to plan sorties and load data into the stealth fighter.
• The contract may include other systems such as the AN/WSN-12 inertial navigation system.

This redesign effort may indicate the Navy's focus on enhancing the operational capabilities of the F-35, which could have significant implications for the future of military aviation. The investment in mission planning software suggests a commitment to improving the effectiveness of the stealth fighter, which could impact the competitive landscape of defense contractors.
