Special

Irian — Pan-Asian special premium Tier VIII cruiser.

This Project 68-bis light cruiser, built as Ordzhonikidze for the Soviet Navy, had good AA defenses and carried twelve 152 mm guns with a very long range of fire. In 1963, the ship was transferred to the Indonesian Navy.

Irian was first released with Update 0.8.0 on 30 January 2019.

Performance

The Pan-Asian Tier VIII Premium cruiser Irian is remarkably similar to her sister ship, Mikhail Kutuzov. There are a few key differences between the two: Irian gains a better torpedo suite, along with the Torpedo Reload Booster  consumable, in exchange for losing Kutuzov’s Smoke Generator , Defensive AA Fire , and some of her range.

Irian owes the largest part of her offensive strength to the twelve 152mm guns she's packing. They have the classic Russian fast shell velocities and low firing arcs, making hitting targets even at the extreme limits of her 17.5 km range much easier than other, similarly armed ships. Unfortunately, the relatively low caliber of these shells necessitates using the commander skill Inertia Fuse for HE Shells to maximize her offense. It gives Irian the punch needed to do direct damage to many of the ships within her tier spread, a cost well worth the loss of fire chance. Be wary though: as with most other cruisers, Irian requires time to do damage with her guns, and is very vulnerable to return fire. Every moment spent spotted and shooting is time that the enemy team can fire back at her. Irian must be played with care, using her range and excellent shell ballistics to keep enemies at arm's length.

However, should captains find themselves a touch closer to their foes, Irian possesses a stinger — potent deepwater torpedoes. While these lose the ability to harm destroyers, they are perfect for taking down larger ships. At 13.5 km they are the long ranged and are very stealthy with a sizeable punch. While getting into the ranges required to use them is risky due to Irians’ relative fragility, they are a welcome addition to her arsenal — especially with her Torpedo Reload Booster consumable that allows captains to quickly launch a second salvo.

Overall, Irian has an very high ceiling in terms of offensive firepower in exchange for not being overly stealthy or well-armored. She is very much a glass cannon, but one that will make her impact felt in any battle, whether she ultimately sinks or not.

Pros:

• Twelve long range, high velocity 152mm guns.
• One quintuple-tube torpedo launchers on each side with, long range, and stealthy torpedoes.
• Solid anti-aircraft suite.
• Equips the Torpedo Reload Booster  consumable for quickly reloading her torpedoes.
• Good base 12% fire chance on HE shells.

Cons:

• Requires IFHE to deal direct damage to 32mm plating.
• Lacks the Smoke Generator  of her sister ship Mikhail Kutuzov.
• Very lightly armored; capable of taking damage from nearly any angle.
• Flat shell arcs of her guns make utilizing islands as cover difficult.
• Rudder shift time is very sub-par for her tier; as a result, she handles somewhat sluggishly.

Research

As a premium ship, Irian has no module upgrades to research.

History

Design

The Sverdlov-class light cruisers were a development over the Chapayev-class, which was still a design from the World War II era. While the armor and main armament of the ships were to remain the same, other improvements were desired.

Compared to the Chapayevs, the Sverdlov class was noticeably enlarged. With an overall length of 212 meters, a 22 meter beam, and a draft of almost 7.4 meters, these ships could displace up to 16,600 tons when fully loaded. The crew complement counted 1,270 men. As light cruisers, the main armament was fairly standard for ships of their time: four turrets, with each housing three 152mm L/57 B-38 guns, were mounted on the centerline. Firing a 55kg heavy shell at ranges of up to thirty kilometers, these guns could fire six-and-a-half rounds every minute.

Auxilliary armament saw twelve twin-mounted 100mm/70 dual purpose guns, with three mounts on each side of the ship. Each gun could fire a 15.6kg heavy shell with up to 18 rounds per minute. The automatic AA guns consisted of 16 twin mounts with fully automatic 37mm/70 guns. Two quintuple Torpedo launchers and up to 132 mines were also installed.

The armor protection was identical to that of the preceding Chapayev class. The vital areas were protected by a 100mm strong belt, which was closed by a 100mm strong bulkhead to the rear and 120mm to the front. A 50mm thick deck provided protection against plunging shells and bombs. The main armament was protected by 130mm strong barbettes, while the turrets featured a 175mm face plate and 60-75mm thick sides and roof. For the conning tower, 130mm armor for the sides and a 100mm roof were deemed sufficient.

Six boilers produced steam for two turbines, which could generate 110,000 shaft horsepower on two shafts. This allowed for a designed top speed of 32.7 knots, and with enough fuel — greatly improved over the Chapayev class — for a cruising range up to 5,700 nautical miles at 17 knots.
