Che io sappia si prevede la sostituzione, poi la coesistenza ci sarà visto il rateo di consegne sonnolento delle nuove blindo. Tra l'altro dalle ultime informazioni che ricordo le B1 in servizio sono più delle B2 previste, ma dovrebbero essere sotituite in parte anche dai Freccia Esplorante.

For years, the service has debated whether a future trainer—which would also be used for Marine Corps pilots—must be able to operate from a carrier like the T-45 does. Operational aircraft such as the Lockheed Martin F-35 are capable of autolanding on the ship. An Undergraduate Jet Training System (UJTS) request for information (RFI) released in mid-August provides a compromise: The future trainer would not be designed to go to the ship, but would need to be able to endure repeated unflared landings to practice the carrier flight profile.
