Seeing through on its promise, the United States recently delivered 31 M1 Abrams tanks to Ukraine in its fight against Russia. This tank is a formidable weapon, known for its first-rate crew protection, and is said to be one of the best, if not the best, battle tanks ever deployed. Despite its many advantages, and being one of the most powerful weapons in the American military arsenal, the Abrams tank is only third in terms of horsepower among the armored vehicles that the U.S. military employs. (Here are 20 Prototype Tanks Rejected by the US Army.)
24/7 Wall St. reviewed data on active U.S. Army vehicles from Military Factory, an online database of military vehicles, aircraft, arms, and more. All vehicles were ranked according to horsepower to determine the U.S. Army vehicles with the most powerful engines. Supplemental information on top speed, crew size, when the vehicle entered the service, and what role it plays within the military also came from Military Factory.
The majority of vehicles listed here first went into service in the 20th century and are still essential to the defense of the nation. Three of the four least powerful vehicles are also among the fastest: the M1161 Growler fast attack vehicle, the infantry squad vehicle, and the Flyer-72 ALSV (advanced light strike vehicle). All go at least 85 mph. (See The 15 Largest Tank Battles in History.)
Seventeen vehicles listed can be categorized in the group of built-to-last, having come into service in the 20th century, and four date from the 1960s. The oldest is the M113 APC-tracked armored personnel carrier that came into service in 1960. Among the five most powerful, two are from the ‘60s, one from the ‘80s, and two from the aughts.
