but these were removed early in her career to make way for more crew accommodations. She also carried two triple and two twin, above-water, torpedo tube mounts for torpedoes. The triple mounts were fitted on either side of the upper deck, aft of the aircraft catapults, and the twin mounts were one deck lower on either side, covered by hatches in the side of the hull. The ship lacked a full-length waterline armor belt. The sides of her boiler and engine rooms and steering gear were protected by of armor. The transverse bulkheads at the end of her machinery rooms were thick forward and three inches thick aft. The deck over the machinery spaces and steering gear had a thickness of 1.5 inches. The gun turrets were not armored and only provided protection against muzzle blast and the conning tower had 1.5 inches of armor. Trenton carried two floatplanes aboard that were stored on the two catapults. Initially these were probably Vought VE-9s until the early 1930s when the ship may have operated OJ-2 until 1935 and Curtiss SOC Seagulls until 1940 when Vought OS2U Kingfishers were used on ships without hangars. Armament changes During her career Trenton went through several armament changes, some of these changes were save weight, but others were to increase her AA armament. The lower torpedo tube mounts proved to be very wet and were removed, and the openings plated over, before the start of World War II. Another change made before the war was to increase the 3-inch guns to eight, all mounted in the ship's waist. After 1940, the lower aft guns were removed and the casemates plated over for the same reason as the lower torpedo mounts. The ship's anti-aircraft armament were augmented by three twin Bofors guns along with 12 Oerlikon cannons by the end of the war. Inter-war period On 24 May 1924, she stood out of New York Harbor for her shakedown cruise in the Mediterranean Sea. On 14 August 1924, while in transit from Port Said, Egypt, to Aden, Arabia, she was ordered to Bushire, Persia. She arrived on 25 August, and took on board the remains of Vice Consul Robert Imbrie. She received and returned the gun salute to the late vice consul and departed the same day. Following stops at Suez and Port Said, Egypt; and at Villefranche, France; Trenton arrived at the Washington Navy Yard
