Countries with old, outdated air forces struggle to compete with the newest generation of fighter jets, which is part of the reason why the United States is considered to have one of the strongest air forces in the world. While the U.S. Air Force does employ some of the newest combat aircraft on the planet, it is also home to some of the oldest. (These are the most widely used fighter jets on Earth. )

Here, 24/7 Wall St. is looking at some of the oldest and newest combat aircraft in the U.S. Air Force. To identify the oldest and newest combat aircraft in the United States military, 24/7 Wall St. reviewed the 2024 World Air Forces report from FlightGlobal, an aviation and aerospace industry publication. We ranked these aircraft according to when they entered service with data from Military Factory , an online database of arms, vehicles, and aircraft. We also included supplemental data on how many of these aircraft are in active service or on order, the type of aircraft, as well as what military branches they serve in.

Some of the combat aircraft in the employ of the United States were introduced back as far as the 1950s. Even though some of these entered service more than half-a-century ago, constant upgrades and advancements have kept these planes in the fleet. The B-52 strategic bomber is one example of these older combat aircraft still fielded by the U.S. Air Force that still serves next to the newest iterations of the F-35 Lightning II.

Another example of an older aircraft that has proved resilient over the years is the F-15 Eagle which was first introduced to service in 1976. Currently there are over 375 of these fighter jets in active service in the U.S. Air Force, with more than 100 on order.

One last thing to note is that the B-21 Raider is currently in the works for the U.S. Air Force. Although it is not in service yet, it has made some preliminary test flights and there are a few of these stealth bombers in stock, but the U.S. Air Force has not disclosed that number. (This is every rank in the U.S. Air Force and what they're paid. )
