What planet are you from? Haven’t you been paying attention to the North Korean nuclear arms development and long range missile tests...
The F-15 entered service in 1974. It's 35 years old. They're breaking in half due to cumulative stress on the structural members. They have flight restrictions on maneuvering due to structural failures. They aren't stealthy. They're vulnerable to SAMs. They don't maneuver as well as the new Russian and French aircraft with thrust vectoring and that makes them vulnerable during BFM engagements.
You're wrong. Delaying the the F-22 puts US Pilots and the US at risk. The longer we delay on the F-22 the more expensive it gets and the higher the risk to US Security.
Here’s another fact to consider. The F-22 isn’t just for fighting other aircraft. It’s also used to intercept Cruise Missiles. Most developed countries have some type of Cruise Missile - Including Iran and Korea. These missiles pose a threat to American interests overseas, including oil production facilities and shipping.
