The C-130 family of planes is the longest continuously produced military aircraft in history.
Why it’s famous: The Hercules can refuel other aircraft in flight. It can fly a small military force and its heavy equipment around the world — and land on short, unfinished airstrips. It’s also used for firefighting, search and rescue and for flying through dangerous storms to gather scientific data.
How many have been made? Lockheed Martin has produced many variations of the C-130 since it entered service in 1956. More than 2,500 have been delivered, and it has logged 1.5 million flight hours.
