After the Space Shuttle was retired in 2011, the United States had to rely on Russia to bring astronauts to and from orbit. Today, we’re preparing for SpaceX and Boeing to fly crews to the International Space Station. In the last decade, the F-35 entered its second decade of development; today, more than 400 aircraft have been delivered.
