Performance

Tier V Omaha represents an incremental improvement over her predecessor, Phoenix. She inherits Phoenix's unusual mixture of casemate and turret-mounted main armament, allowing a broadside of eight 6-inch (152 mm) guns or six guns fore and aft. The casemate guns have very good angles of fire and at least six guns can be brought to bear in any direction. This is useful when pursuing a target or retreating, allowing Omaha to maintain most of her firepower without giving a broadside.

Omaha is also the last torpedo-armed cruiser in the American line. Unfortunately, the torpedoes on all hulls have a paltry 5.5 km range (unlike her Soviet Lend-Lease counterpart, Murmansk, which has 8 km torpedoes), and should be used only when the guns cannot do enough damage (from either damage saturation for HE or insufficient penetration for AP) or Omaha finds herself very close to another ship. The good news is that if a torpedo salvo hits, it will do massive amounts of damage. They become very useful when ambushing in close quarters. With the removal of the C hull(a older version of it can be found on Marblehead ) players now find themselves in a good and bad place, the bad news is that they cannot boost their AA as good as before but the good news is now they can grind faster and focus on playing against ships more.

Befitting her status as a light cruiser, the armor fitted on Omaha is fairly weak. She relies mainly on speed to avoid damage from other ships, and dodging shells and torpedoes is key to surviving. Her quick rudder shift provides her captain the ability to make her a difficult target to hit, and he must maximize use of her rudder to avoid being blown away by enemy battleships. Omaha also has a rather large and vulnerable citadel; giving a broadside to battleships, cruisers, or even destroyers will result in the ship taking massive amounts of damage, if not being destroyed in a single salvo.

As a teammate, Omaha is the perfect escort for battleships. She provides decent AA cover, extra firepower, and Hydroacoustic Search  to see where torpedoes are coming from far in advance. Omaha also excels at chasing down and killing destroyers thanks to her high speed and unusual armament layout. Her added firepower can be a useful supplement in supporting allied destroyers.

Prós:

• High damage per minute, even without firing a broadside.
• Speed that matches destroyers of that tier and above.
• Can aim six guns forward; very good when pursuing enemy targets.
• Can also aim six guns to the rear; very good when kiting away from enemies.
• Good fire starting capabilites.

Contras:

• Virtually no armor: bow and stern are both 13mm, which means they get overmatched easily, even by some same tier CAs. The deck and upper belt are 16mm which means they're overmatchable by every BB in her matchmaking range. Citadel armor is 76mm on the sides and back and 37 on the top and the front, which means even DDs can easily pen it.
• Torpedoes are rather slow at 56 knots, having a range of only 5.5 km.
• Poor AA defenses especially with the removal of hull C in 0.10.3 update.

Early experience gains are best invested in Hull (B) — providing significant upgrade to Omaha’s firepower — followed quickly by the improved 152mm guns. Boost her firing range next by picking up the Fire Control System upgrade, then unlock Hull (C). Investing the credits to equip Hull (C) is the captain's choice: it sacrifices two of her torpedo launchers for additional anti-aircraft defenses and is a downgrade to her overall firepower. For the purposes of unlocking Dallas, sticking with Hull (B) is probably best.

History

Design

The Omaha-class cruisers were a class of light cruisers built for the United States Navy. The oldest class of cruiser still in service with the Navy at the outbreak of World War II, the Omaha class was an immediate post-World War I design.

Maneuvers conducted in January 1915 made it clear that the US Atlantic Fleet lacked the fast cruisers necessary to provide information on the enemy's position and to deny the enemy information of the fleet's own position and to screen friendly forces. Built to scout for a fleet of battleships, the Omaha class featured high speed (35 knots) for cooperation with destroyers, and 6-inch (152 mm) guns to fend off any destroyers the enemy might send against them. Displacing 7,050 tons, they were just over 555 feet long.

The Omaha class was designed specifically in response to the British Centaur subclass of the C-class cruiser. Although from a modern viewpoint, a conflict between the US and Great Britain seems implausible, US Navy planners during this time and up to the mid-1930s considered Britain to be a formidable rival for power in the Atlantic, and the possibility of armed conflict between the two countries plausible enough to merit appropriate planning measures.

The Omaha class mounted four smokestacks, a look remarkably similar to the Clemson-class destroyers (a camouflage scheme was devised to enhance the resemblance). Their armament showed the slow change from casemate-mounted weapons to turret-mounted guns. They held a full twelve 6-inch/53 caliber guns, of which four were mounted in two twin turrets, one fore and one aft, and the remaining eight in casemates; four on each side. Launched in 1920, Omaha (designated C-4 and later CL-4) had a displacement of just over 7,100 long tons. The cruisers emerged with a distinctly old-fashioned appearance owing to their World War I-type stacked twin casemate-mount cannons and were among the last broadside cruisers designed anywhere.

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 ships were insufficiently insulated, too hot in the tropics and too cold in the north. Sacrifices in weight savings in the name of increased speed led to severe compromise in the habitability of the ship. 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 casements. The lightly built hulls leaked, so that sustained high-speed steaming contaminated the oil tanks with sea water.

These drawbacks notwithstanding, the US Navy took some pride in the Omaha class. They featured improved compartmentalization; propulsion machinery was laid out on the unit system, with alternating groups of boiler rooms and engine rooms, to prevent immobilization by a single torpedo hit. Magazines were the first to be placed on centerline, below the waterline. A serious flaw in these ships' subdivision was the complete lack of watertight bulkheads anywhere above the main deck or aft on the main deck.

Originally designed to serve as a scout, they served throughout the interwar period as leaders of fleet flotillas, helping them resist enemy destroyer attack. Tactical scouting became the province of cruiser aircraft, and the distant scouting role was taken over by the new heavy cruisers spawned by the Washington Naval Treaty. Thus, the Omaha class never performed their designed function. They were relegated to the fleet-screening role, where their high speed and great volume of fire were most appreciated.

Due to the large topweight lasting on these ships, compounded by the high-mounted catapults, the Navy removed the two lower aft firing casemate-mounted 6-inch guns in 1939, fairing over the casemates port and starboard.

Service

These were the oldest class of cruisers still in service with the Navy in 1941. All were modified during the war with additional 20mm and 40mm anti aircraft guns and radar.

Both USS Detroit and USS Raleigh were at Pearl Harbor during the attack, with Raleigh being torpedoed. Detroit and USS Phoenix were the only large ships to get out of the harbor during the attack.

The ships of the Omaha class spent most of the war deployed to secondary theaters and in less vital tasks than those assigned to more recently built cruisers. The Omaha class were sent in places where their significant armament might be useful if called upon, but where their age and limited abilities were less likely to be tested. These secondary destinations included patrols off the East and West coasts of South America, convoy escort in the South Pacific far from the front lines of battle, patrols and shore bombardment along the distant and frigid Aleutians and Kuril Islands chains, and bombardment duty in the invasion of Southern France when naval resistance was expected to be minimal. The most significant action than any of the ships of the class saw during the war was Marblehead’s participation in early war actions around the Dutch East Indies (most notably, the Battle of Makassar Strait), and Richmond’s engagement in the Battle of the Komandorski Islands.

None of the ships were wartime losses. Raleigh‍’​s torpedo damage at Pearl Harbor and Marblehead‍’​s damage at Makassar Straight were the only significant wartime combat damage suffered by the class.

The ships of the class were considered obsolete as the war ended, and were decommissioned and scrapped within seven months of the surrender of Japan (with the exception of Milwaukee, which had been loaned to the Soviet Navy, and was scrapped when returned to US Navy control in 1949).

Historical Inaccuracies

• Omaha’s Measure 33, Design 2F camouflage scheme is missing.
• Hull (B) is fictitious. Omaha-class cruisers carried only two quadruple 1.1-inch (28 mm) anti-aircraft guns, one fore and one aft of the ship.
