The US Navy and Marine Corps plan to upgrade some of their most versatile jet strike fighter aircraft, extending the platforms’ service life for a couple thousand more flight hours.

Boeing, a leading American defense company, recently received a $313.4 million contract to support the enhancement of up to 25 F/A-18 E/F Super Hornet fighter jets from the Navy fleet.

The contract covers “non-recurring engineering, system engineering program management, and additional aircraft inductions,” which will integrate Block III avionics capabilities, extending the service life of these warplanes from 6,000 flight hours to 10,000 hours and generally boost the overall performance of the Super Hornets.

Boeing plans to finish the upgraded aircraft by February 2025.
