In March she took part in the Her shakedown cruise was in Mediterranean ports. Omaha (A) Omaha (B) 3,400. Sacrifices in weight savings in the name of increased speed led to severe compromise in the habitability of the ship. In 1927, USS Memphis carried Captain Charles A. Lindbergh and his plane at Southampton after his successful New York to Paris flight. Originally designed to serve as a scout, they served throughout the interwar period as leaders of fleet flotillas, helping them resist enemy destroyer attack. La classe Omaha est une classe de croiseurs légers construits pour la Marine des États-Unis après la Première Guerre mondiale.
Mk5 mod. Thus, the Omahas never performed their designed function. In 1944, the Milwaukee was transferred to the USSR as a lend-lease becoming the Murmansk, to provide escorts from that port. Torpedoes. Magazines were the first to be placed on centerline, below the waterline.
Already in 1918, there was an alternative design, which was dropped but looked more promising: This new class and height 6-inch guns in four turrets forward and aft, and there was another alternative version intended to function as a monitor with two 14-inch guns in 2 single turrets. The Omaha class placed a high emphasis on underwater explosion protection from the threat of torpedoes. Their armament showed the slow change from As a result of the design changes placed on the ship mid-construction, the Omaha that entered the water in 1920 was a badly overloaded design that, even at the beginning, had been rather tight. The Omaha Class Light Cruiser will almost certainly not make the most elegant ship category, but it does have a certain charm about it.
They were launched in 1920-23 completed in 1922-24, bearing the names of southern American cities (Omaha, Milwaukee, Cincinnati, Raleigh, Detroit, Richmond, Concord, Trenton, Marblehead, and Memphis).Built lightly, they relied on speed and were part of this generation so-called “tin-clad cruisers”, relying on speed as their only protection at a time rangefinder still lacked precision for fast-moving targets. The war broke up when she was undergoing extensive overhaul from 17 June until October 1939.She then operated in the Caribbean and was based in Lisbon to protect US citizens interests and relieve the ships which had done so after the Spanish civil war.
She was the first cruiser in the U.S. Navy to receive aircraft handling equipment.
The next year she was part of the Scouting Fleet off Guantánamo Bay, Cuba. After an overhaul at New York in 1944 she escorted convoys from New York to Belfast, until July 1944 sailed for the western Mediterranean to take part in the Provence landings, then back to New York for a last overhaul. She covered the operations against the Japanese garrisons on Kiska and Attu and remained in Alaskan waters until 1944. She later joined the cruisers Phoenix and St. Louis and two destroyers to investigate any possible IJN landing at Oahu.She then took part in Convoy escorts between her home port and the West coast, and from November 1942 she sailed for Kodiak, Alaska, and became a flagship for the Task Group 8.6 (TG 8.6), that took part in the Aleutian islands campaign. She then patrolled the waters of Panama in 1942 and made convoys escorts to the Galápagos Islands and the Society Islands and then the South American lanes.By 1943 she was sent in the Aleutian waters. After repairs at Norfolk Navy Yard, Portsmouth, Virginia, the ship sailed to Gibraltar on 30 March 1938, and served in the Mediterranean Sea until May 1939.
They were designed with improved compartmentalization; propulsion machinery was laid out on the unit system, with alternating groups of boiler rooms and engine rooms, in order to prevent immobilization by a single torpedo hit.
Rate of fire was 15–20 rounds per minute at a muzzle velocity of 2,700 ft/s (820 m/s).There was also a set of ten torpedo tubes, spread into two triple and two twin 21 in (533 mm) torpedo tubes, with reloads. In 1927-28 she showed the flag off Nicaragua, and from Pearl Harbor, sailed with USS Richmond and Trenton to Shanghai, showing the flag during China’s civil war. Maximum range was 14,600 yards °45 in elevation up to 29,800 feet (9,100 m) in ceiling at 85°.
At that time, the Chesters were already 8 years old and were not enough in numbers compared to the massive battleships construction plans.The first specifications called for high speed (35 kn (65 km/h; 40 mph)) to lead and cooperate with destroyers, and having the firepower to over-match them as well. The Omaha were the first American cruisers after a very long eclipse dating back to 1907 (the Chester). Pensacola .
Like them, they had this typical flush-deck and four funnels.Almost scaled-up versions used as destroyer leaders.
She was back to Pearl Habor, then Philadelphia where she was decommissioned.in 1923, USS Trenton made shakedown cruise in the Mediterranean Sea, visiting Port Said, Egypt, Aden, Arabia, and Bushire, Persia.
