The Slowest Planes Currently Used by the US Military

When people think of planes used by the United States Military, they may often envision fast jets – fighter planes that are capable of moving at supersonic speeds of mach 3 and even higher. But these aren’t the only planes used by the armed forces. Speed is not always necessary for a mission; at times, slow planes are often essential for the task at hand.

These slow-speed aircraft may not have the allure and thrill of their high-speed counterparts, but they play an indispensable role across diverse military operations. Engineered for low-speed maneuvers, these planes excel in tasks like maritime patrol, reconnaissance, surveillance, and transportation. Aircraft like the AC-130 can provide utility in close air support to ground troops on battlefields.

Slow-speed aircraft are not only functional in operational roles but they serve as valuable training assets addition. The Cirrus SR20, for instance, enjoys popularity within the U.S. Air Force, functioning both as a training platform and a preparatory stage for cadets before progressing to more advanced aircraft. (On the other hand, these are the world’s 13 fastest fighter jets.)

24/7 Wall St. determined the slowest planes the U.S. armed forces use by reviewing a list of U.S. military aircraft produced by Military Factory, an online database of military vehicles, aircraft, arms, and more. Aircraft with top speeds lower than 350 miles per hour were ranked according to their top speed, from fastest to slowest. Supplemental information on military branches using the aircraft and the aircraft’s role came from the World Directory of Modern Military Aircraft. The dates of these aircraft’s first flight came from both WDMMA and from Military Factory.

Among the slowest military aircraft currently in operation is the AC-130J, a variant of Lockheed’s Hercules transport plane and a prominent example of how slow an aircraft can be. It has a top speed slightly surpassing 300 miles per hour and it offers crucial close-air support during combat scenarios. Varied versions of the AC-130 have played pivotal roles since the Vietnam era, actively participating in the United States’ major military conflicts.

This list is comprised of aircraft spanning diverse categories including trainers, transports, and specialized missions. These planes are deployed across all branches of the U.S. military. Perhaps one of the biggest differentiating factors is the year that each plane was first flown, with some first flown more than half a century ago, while others began flying much more recently. (This is the U.S. Air Force’s oldest aircraft.)
