These were to be carried on either side of the fore and aft superstructures, with two levels of casemates in each position. Sacrifices in weight savings in the name of increased speed led to severe compromise in the habitability of the ship. They caught also lay mines.

While described as a good ship in a seaway, the low freeboard led to frequent water ingestion over the bow and in the torpedo compartments and lower aft casemates. CL-4 to CL-6 were built by Todd.

When the attack took place in December 1941 but she was able to get underway, safely downing several aircraft with a dense anti-aircraft fire, one of her crew receiving the Purple Heart. The Omaha were the first American cruisers after a very long eclipse dating back to 1907 (the Chester).

Omaha ClassCruisers. The Omaha were the first American cruisers after a very long eclipse dating back to 1907 (the Chester). They had White-Forster boilers, Parsons turbines and longer range cruising turbines. Camouflage Measure 32 Design 3C No.2.jpg 1,200 × 600; 101 KB. Visually the Omaha class cruisers greatly resembled the flush-deck destroyers, with four funnels, a small rear superstructure and larger forward superstructure.

10 ships . After sailing back home she participated in a summer training cruise for Naval Academy midshipmen and was decommissioned in 1945 in Philadelphia.After a shakedown cruise in the Caribbean, she toured from Honolulu, Hawaii the South pacific, visiting Australia and New Zealand and was back home through the West Indies in 1926. She participated in manoeuvers from San Diego from then until 1941 where she was sent to Pearl harbor. 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.

The boilers and turbines installed varied depending on the builders. They were propelled by a turbine fed by a propellant combining Air (2800 psi, 23.4 cut), water (90 US pints or 43 l) or Alcohol (49 US pints or 23 l) up to 36 knots (65.1 km/h).There were also rails, helped by the flush-decks, to carry up to 224 mines.

The US Navy had stopped building cruisers ten years before work began on the Omaha class, but there were some clear links to the earlier designs. However it was observed that sustained high-speed steaming can contaminate the oil tanks with sea water, because of leakages and the low freeboard causing water to be ingested through doors, vents, deck hatches, or torpedo and barbettes rear openings.Poorly insulated, these cruisers were icy and wet in winter, but furnaces in summer under the tropics.

She also shelled Japanese installations at Paramushiru in the Northern Kuriles. In September she was back in southern Atlantic, operated with the Brazilian Navy from then on, and in December she underwent her last refit at the New York Navy Yard. Technical information. They were built with the twin bank and with two triple banks of torpedo tubes.

he participated in the operations against the IJN at Holtz Bay and Attu Island then Attu and Kiska. They were designed to have an endurance of 10,000nm at 10kts, but rarely managed to achieve this. With the same equipment described above she also found in 1939 the deepest Atlantic depression, the “Milwaukee Deep”.She took part in neutrality patrols, and was overhauled at the Brooklyn Navy Yard when the war broke out with Japan.She operated then in the Caribbeans, and later escorted convoys between Brazil and the African coast, rescuing survivors of sunken freighter, trying to spot and destroyer submarines and German blockade runners.
