The Pentagon has awarded Boeing a contract worth nearly $20 billion to develop a sixth-generation fighter planned to operate from aircraft carriers for the U.S. Navy.
Under the F/A-XX program, multiple test aircraft will be procured for flight-readiness testing, ground evaluations, and the integration of systems and weapons.

F/A-XX is set to join the fleet in the 2030s
The new fighter is expected to enter service with the U.S. Navy fleet in the 2030s. Boeing is also expected to begin delivering F/A-XX aircraft during the same period.
Michael P. Duffy, the U.S. Department of Defense’s Under Secretary for Acquisition and Sustainment, described the program as a key element of the United States’ commitment to “peace through strength.” Duffy said the aircraft is expected to provide air superiority, extend the range of operations, and give combat forces a decisive advantage in conflicts. He said Boeing would work to deliver these capabilities to the U.S. inventory as soon as possible.
Acting Secretary of the Navy Hung Cao said the F/A-XX would represent a significant generational leap in air superiority and expressed satisfaction with the cooperation with Boeing.

It is planned to replace the Super Hornet and Growler
The F/A-XX aircraft are expected to support the F/A-18E/F Super Hornet and EA-18G Growler aircraft currently in service. The new aircraft are planned to gradually replace these models over time and operate alongside F-35C fighter jets.
