Built as a basic trainer, the T-28 undertook carrier operations with the US Navy. This 800-horsepower piston engine aircraft flies with a top speed of a 285 mph. Later versions were equipped with a 1,425-horsepower Wright R-1820 engine, allowing the plane to reach up to 345 mph in speed. Thanks to its powerful engine, the Trojan made an ideal counter-insurgency aircraft during the Vietnam War. It was also an efficient close-air support aircraft against adversary ground forces. Before retiring in 1944, the T-28 served as a dive-bomber aircraft during the 1989 Philippine coup attempt.
