The Thai Army was a relatively well-equipped force. Consisting of some sixty thousand men, with artillery and tanks. The Royal Thai Navy—consisting of several vessels, including two coastal defence ships, twelve torpedo boats and four submarines—was inferior to the French naval forces, but the Royal Thai Air Force held both a quantitative and qualitative edge over l'Armee de l'Air. Among the 140 aircraft that composed the air force's first-line strength were twenty-four Mitsubishi Ki-30 light bombers, nine Mitsubishi Ki-21 and six Martin B-10 twin-engine bombers, seventy Vought Corsair dive bombers, and twenty-five Curtiss Hawk 75 fighters.
