Keys further said he doesn’t foresee a “train wreck” in tactical forces, where large numbers of airplanes must retire before the new ones arrive, although “there’s always an opportunity for a train wreck to happen” if a huge technical problem grounds a fleet. Keys said he’s willing to trade “a little risk” in the form of a short-term drop in fighter tails, if it means he can get the F/A-22 and F-35 on schedule. Keys added that the Air Force will have enough warning to take steps to keep the fighter fleet viable a while longer, but the cost would be unappetizing. When they come on line, the F/A-22 and F-35 will rapidly overcome any capability lost to a shortage of tails, he said.
The Air Force’s Hypersonic Attack Cruise Missile is behind schedule and may significantly overrun its expected cost, which could partially explain why the service is reviving the hypersonic AGM-183 Air-Launched Rapid-Response Weapon.
