Aerial Armada Assembles Off Iran: "The mix of old and upgraded F-15s and ultra-modern F-22s is no accident. When the Pentagon stopped producing the nearly $400-million-a-copy Raptor after 187 units — half as many as the Air Force said it needed — the flying branch committed to keeping 250 F-15Cs in service until 2025 at the earliest. Pilots began developing team tactics for the two fighter types.
“We have a woefully tiny F-22 fleet,” said Gen. Mike Hostage, the Air Force’s main fighter commander. So the flying branch worked out a system whereby large numbers of F-15s cover for small numbers of Raptors that sneak in around an enemy’s flank in full stealth mode. “Our objective is to fly in front with the F-22s, and have the persistence to stay there while the [F-22s] are conducting their [low-observable] attack,” Maj. Todd Giggy, an Eagle pilot, told Aviation Week."
