Omono — Japanese Tier VII cruiser.

The development of the Ōyodo-class cruisers—the flagships of submarine squadrons—into full-fledged light cruisers with four triple-gun turrets that housed 155 mm guns. Unlike her predecessors, the ship had no aft-end hangar, the catapult was moved to the center, two torpedo launchers were added, and her AA defenses were enhanced.

Tier VII Omono continues the theme of the Japanese light cruiser line, where hard hitting torpedoes are coupled with relatively low main battery DPM, and slow turret traverse times.

The Ship

When compared to her predecessor, Omono can feel like she lacks mobility. She retains a somewhat large turning circle of 740 meters, with a longer rudder shift time of 8.8 seconds. In comparison to Gokase, her top speed has been slashed to 33 knots. Although this is similar to many other Tier VII cruisers, it is slower than other Japanese cruisers. In confined areas or short ranges, she will feel unwieldy. Omono carries a standard cruiser Damage Control Party  consumable. She mounts a Catapult Fighter  with 3 charges, launching three aircraft which will patrol for up to 60 seconds. Players also have the choice of a standard Tier VII cruiser Hydroacoustic Search  or Defensive AA Fire . Her Hydroacoustic Search is active for 100 seconds, and will detect ships at 4 km, and torpedoes at 3 km. Her Defensive AA Fire provides a 50% boost to her continuous AA damage, and quadruples her flak burst damage.

Armor and Survivability

Omono is lightly armored; her citadel is protected by just 76 mm of armor. She is vulnerable to most cruiser AP at all combat ranges, and even destroyer-caliber guns pose a serious threat at short ranges. Additionally, as the main part of her citadel sits above the waterline, shells which hit amidships can cause serious damage. The sections beneath her turrets are slightly better protected, as they sit below the waterline, and have spaces between her outer plating and citadel.

Her main deck armor is 25 mm thick, sufficient to prevent AP overmatch from battleship guns smaller than 380 mm. Her main hull plating is 16 mm thick; this is enough to bounce 203 mm AP rounds if she is sufficiently angled, but is vulnerable to overmatch from battleship guns and the larger guns found on some cruisers. Additionally, all destroyers in her matchmaking spread are capable of penetrating her with HE rounds.

Omono has a rather small health pool, when coupled with her thin armor she can be vulnerable to rapidly losing health if players are caught out of position. With a base concealment of 11.9km, OMONO is not particularly stealthy for a lightly armored vessel. Her concealment can be reduced to 10.7km, enough to ensure she cannot be easily ambushed but she lacks options for disengaging from unfavorable situations. As she lacks a smoke screen or heal, any mistakes can easily be punished.

Armament

Omono’s main battery consists of somewhat unusual 155 mm guns, which are slightly larger than typical light cruiser weapons. Her 11.5 second reload is relatively long for a light cruiser. This means that her DPM can feel lackluster when compared to other light cruisers. When upgraded, her range of 16.1 km allows her to keep enemies at arm’s reach, while still being able to engage slower targets. She has the slow turret rotation typical of Japanese ships, with a 180° rotation taking 30 seconds she can struggle to rapidly change targets. Although it can be tempting to turn the ship to bring her guns to bear more quickly, this will put players at risk of exposing too much broadside.

Her AP shells have good penetration for a light cruiser, and they retain their speed and penetration well over range. However, at long ranges, they still pose little threat to all but the thinnest armored targets. In contrast, her HE shells present players with a choice. Omono is a fairly poor fire starter. With a 10% fire chance and only 6.3 potential fires per minute, she will even struggle to match the fire starting potential of several heavy cruisers. Players who can afford to invest in the [u]Inertial Fuse for HE Shells[/u] skill will find that her HE shells are capable of directly damaging a much larger range of targets than the typical light cruiser shells. With 32 mm of penetration, her guns are capable of penetrating the bow and stern plating of any battleships she will meet, as well as the deck armor of many French and British battleships.

Omono mounts two quadruple torpedo launchers, which fire some of the most powerful torpedoes in her tier, with high alpha damage and good flooding chance. A range of 13 km means that they can be fired while undetected; this reduces the chances of taking damage, but also limits the chances of the torpedoes hitting their intended target. Her launching angles are less restricted than players may expect for a Japanese cruiser, but care should be taken if trying to launch torpedoes while spotted. Additionally, their slow speed of 57 knots gives targets 11 seconds of reaction time, one of the worst at her tier, further reducing their chances of hitting. Finally, her torpedoes take 2 minutes to reload, limiting the number she can launch in a single battle. Overall, her torpedoes are a potentially devastating weapon, but they are held back by their speed, detection, and reload.

Anti-Aircraft

Omono has a good long-range AA DPS, only slightly behind Atlanta, Flint, and Chumphon. Her short-range AA DPS is also one of the best at her tier. However she lacks any medium-range aura, so she must rely on her long-range weapons until enemy aircraft are already commencing their attack run. Omono fires 4 flak clouds per salvo; this can be devastating to an enemy strike, if they are unable to avoid the clouds. Omono’s anti-aircraft firepower can be increased with the Defensive AA Fire consumable, however doing so will mean giving up her Hydroacoustic Search.

Anti-Submarine

Omono carries a standard Tier VII cruiser ASW airstrike, with 2 charges available, a range of 6 km, and each attack dropping a single bomb. She is able to strike a detected submarine from relative safety. To aid in ASW attacks, she can use her Hydroacoustic Search, which will detect a fully submerged submarine at a range of 2 km.

Battle Performance

Omono can be a difficult ship to play. She is suited to keeping her enemies at distance, in order to mitigate her thin armor and slow turret traverse. Remaining at range also allows her to work around her fairly poor maneuverability. Her torpedoes can be used as area denial weapons, as their slow speed means that they remain active for a considerable time.

Omono is suited to a supporting role in battle; players who become the focus of enemy attention can expect a swift return to port. Her performance is often throttled by her armament limitations, and her survivability. Individually, her torpedoes are strong, but they are hampered by their slow reload, low speed, and the high reaction time available. Her gunnery is held back by her poor reload and turret traverse.

Pros:

Large amount of guns with decent firing range
High damage per salvo
Strong torpedoes, with high damage and range
Good concealment

Cons:

Abysmal armor
Turrets are prone to incapacitation
Long reload on guns
Low AP shell damage and penetration
Torpedoes have slow speed and high detectability
Terrible turning circle for a light cruiser
Low speed for a Japanese cruiser

Research

Researchable upgrades for Omono:

Hull: Upgrade to Hull (B) for improved survivability, maneuverability and AA. Research of this module unlocks progression to Shimanto.
Gun Fire Control System: Upgrade to Type7 mod. 2 for an extra 10% range on the main battery.
