== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} Japanese naval bomber {{Battle-rating}}. It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The Allied reporting name for this aircraft was "Kate".

== General info ==
=== Flight performance ===
The B5N2 has Zero-like maneuverability and is able to dodge nearly every anti air by ships and on the ground. It can pull very sharp 180° turns after dropping it's torpedo. It's great agility gives you the ability to use islands and boulders for hiding from your opponents very quickly.{{Specs-Avia-Flight}}

=== Survivability and armour ===
{{Specs-Avia-Armour}}


* No armour
* Non-self-sealing fuel tanks (2 in each wing)
* Very good maneuverability (your only chance to survive attacks)

=== Modifications and economy ===
{{Specs-Economy}}

* When upgrading this plane focus on getting the payload especially the torpedo modification. This is due to the high chance Japan has to get naval maps.
* After you've unlocked all the possible torpedoes, it is recommended that you research the flight performance modules first, as the aircraft has very little defensive and offensive capabilities.

{{main|Type 91 Model 3 (850 kg)|Type 91 Model 2 (835 kg)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 6 x 60 kg Navy Type 97 Number 6 bombs (360 kg total)
* 2 x 250 kg Navy Type Number 25 Model 2 bombs (500 kg total)
* 2 x 250 kg Navy Type 98 Number 25 bombs (500 kg total)

* 1 x 850 kg Type 91 Model 3 torpedo

=== Defensive armament ===
{{Specs-Avia-Defensive}}

{{main|Type 92 (7.7 mm)}}

The '''''{{PAGENAME}}''''' is defended by:

* 1 x 7.7 mm Type 92 machine gun, dorsal turret (1,000 rpg)

== Usage in battles ==


The B5N2 is a Japanese torpedo-bomber that is lacking in offensive armaments and is defended by a single [[Type 92 (7.7 mm)|7.7 mm Type 92]] machine gun at the back, which makes it lacking in defence against enemy pursuers. Its greatest weapon is not the speed to outrun enemy fighters but its maneuverability and ability to do tight turns against most enemy aircraft till help arrives from the team.

The B5N2 might lack in offensive weaponry such as machine guns and cannons but it has a great variety of payload from 60 kg bombs to 800 kg bombs and even torpedoes in its arsenal to take out ground and naval targets with. Coming with 2 different 800 kg bombs, its important to pick the one most suitable for the mission, preferably the [[Navy Type Number 80 Model 1 (800 kg)|Navy Type Number 80 Model 1]] over the [[Navy Type 99 Number 80 AP (800 kg)|Navy Type 99 Number 80 AP]], with the benefit that the [[Navy Type Number 80 Model 1 (800 kg)|Type Number 80 Model 1]] has a better blast radius and more explosive power than the [[Navy Type 99 Number 80 AP (800 kg)|Type 99 Number 80 AP]] bomb which is good at taking out a single heavily armoured target. It also come with two different sets of 250 kg bombs that can be dropped one by one and are preferable when striking at two different targets than a singular 800 kg.

Against naval targets, it's most preferred to use the [[Type 91 Mod.2]] and [[Type 91 Mod.3]] to deal with the sailors, keep in mind to dive and get fast speed to quickly get in and out of engagement with a warship or patrolboat to minimize the risk of being shot down. But when doing a dive attack to get the speed its important to not go over the speed limit where the B5N2 can drop the torpedoes without having them explode in the water on contact which would make the attack futile.

Every enemy should be seen as a serious threat to the B5N2, as it does not have an offensive armament. The only thing the plane has when it comes to armament is 1 7.7 mm machine gun, which is not a reliable way to fend off enemies with it lacks damage and doesn't offer the best coverage, but at 1.7 it might be enough to scare off ill-armoured biplanes.

== History ==

The Nakajima B5N2 (Allied code name: Kate) was a plane first flown in January 1937 for the Imperial Japanese Navy. About ~1149 Nakajima B5N Torpedo bombers were made for the Japanese Navy. It would see service in World war 2 and was the Japanese Navy's primary torpedo bomber for the early part of World war 2. The Nakajima B5N Torpedo bomber was credited with the sinking of three US Carriers the USS Lexington CV-2, USS Yorktown CV-6 and USS Hornet CV-8. One of the most notable pilot of the B5N is Mitsuo Fuchida, who led the first wave of aircraft during the Japanese attack on Pearl Harbor.

Although a total of 5,928 B5Ns were built, none survived the war. Two B5N's are know to exist, both made from wreckage's. One can be seen at the Pearl Harbor Memorial, it is missing it's tail, left wing, engine, canopy, and a few other parts.

=== In-game description ===
Before the advent of the B5N, Japan used the B2M and B4Y as torpedo biplanes. However, the significant limitations of biplanes were obvious, so in 1935, inspired by the monoplane A5M fighter, the Imperial Japanese Navy developed the 10-Shi torpedo bomber specification.

Nakajima and Mitsubishi participated in the competition. Nakajima decided to incorporate many new ideas in their B5N design. The prototype had a hydraulic wing-folding system so that the plane could be stored on an aircraft carrier, and Fowler flaps were used to improve stability while landing. In addition, the B5N had a hydraulic retractable landing gear system.

Although Mitsubishi also received an order for production of its own B5M torpedo bomber, the Nakajima model won the contest and in 1937 was accepted as a production model carrier-based torpedo bomber.

To create a production model, however, some changes had to be made in the prototype's design. The wing-folding system was changed to a manual one, and the flaps were replaced with conventional ones.

In 1939, the B5N2 was developed. It differed from its predecessor in its more powerful and reliable Sakae engine, which produced 1000 hp instead of the Hikari 3's 770.

At the beginning of World War II, the B5N torpedo series had no worthy competitors among Allied aircraft and made a great showing in the attack on Pearl Harbor, as well as in subsequent operations, where B5N forces sank four U.S. aircraft carriers within one year.

A total of 5,928 B5Ns were built.

SMS Helgoland

U44135068: /* Survivability and armour */

{{Specs-Card
|code=germ_battleship_helgoland
|images={{Specs-Card-Image|GarageImage_{{PAGENAME}}.jpg}}
}}

== Description ==

The '''{{Specs|name}}''' is a rank {{Specs|rank}} German battleship {{Battle-rating}}. It was introduced in [[Update "New Power"]].

== General info ==
=== Survivability and armour ===
{{Specs-Fleet-Armour}}

This Helgoland-class dreadnought comes with a thick side armoured belt of 300 mm, and other places being 90 to 170 mm thick. This can stop 356 mm HE rounds except at the higher sections of the bow and stern.

All 6 turrets have thick barbettes, which AP shells have to go through after the already thick side armour.

Ammunition is surrounded by coal bunkers, in addition to a turtle-back armour scheme.

In short: she is one of the toughest battleships in the game, as long as she faces fair opponents.

To survive longer, do not repair secondary battery. Doing so will remove crew from your armoured hull and put it in the vulnerable secondary turrets, for them to be killed again.

=== Mobility ===
{{Specs-Fleet-Mobility}}


{{NavalMobility}}

Being a dreadnought, it was all about armour and firepower. She will reach a little bit over 38 km/h maxed out.

=== Modifications and economy ===
{{Specs-Economy}}

== Armament ==
{{Specs-Fleet-Armaments}}
=== Primary armament ===
{{Specs-Fleet-Primary}}

{{main|305 mm/50 SK L/50 (305 mm)}}

Her primary armament is somewhat lacking for her size. She has 6 turrets, but only 4 can fire at a broadside. 3 can fire most of the time and worst case scenario only 2 will fire.

Her turrets have each double 305 mm guns, this is somewhat lacking for long range fights.

=== Secondary armament ===
{{Specs-Fleet-Secondary}}

{{main|150 mm/45 SK L/45 (150 mm)|88 mm/45 casemate SK L/45 (88 mm)}}

While her primary armament is lacking, she makes it up with great secondaries.

She has fourteen 150 mm guns in casemates all around the ship, and fourteen 88 mm guns with fragmentation shells. Torpedo boats will not like getting close to you.

Even her 150 mm are a real threat to any destroyers, even light cruisers.

=== Additional armament ===
{{Specs-Fleet-Additional}}

{{main|G6c (500 mm)}}

She comes with fixed underwater torpedo tubes. Being an old ship, her torpedoes are not remotely good.

She carries a total of sixteen torpedoes, in several launchers: 1 forward, 1 rear, 2+2 per broadside.

Her torpedoes carry only 160 kg of TNT, which may not be enough to break through the torpedo bulges of other dreadnoughts and heavy cruisers. This means that several hits are needed.

== Usage in battles ==

''Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don't try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).''

=== Pros and cons ===


'''Pros:'''

* Massive firepower, primary and secondary
* Heavily armoured, making it hard to sink

'''Cons:'''

* Has no anti-air defences
* Is very slow
* 305 mm may have difficulties destroying other dreadnoughts from afar

== History ==

[[File:SMS Helgoland.jpg|thumb|SMS Helgoland, Circa 1911-1917.]]
SMS ''Helgoland'' was the lead ship of the ''Helgoland''-class of pre-WWI dreadnought battleships. Being an incremental improvement upon the preceding [[SMS Westfalen|''Nassau'']]-class battleships, they featured a more powerful 12-inch (305 mm) battery and improved propulsion system. Built in 1909, she saw service in World War 1; she served in the raid on Scarborough, Battle of Riga, and Battle of Jutland. After the war, ''Helgoland'' was handed to the United Kingdom as a war reparation; she was scrapped in 1924.<ref name=":0">World War 1 Co. (1998)</ref><ref name=":1">Military Factory. (2020)</ref>

=== Design and construction ===
The ''Helgoland''-class was of overall similar construction to the preceding ''Nassau''-class. They displaced 22,500 tons standard, and with 28,000 shaft horsepower, were capable of making 20 knots (37 km/h).<ref name=":0" /> The ''Helgoland'' featured a unique hexagonal main armament arrangement, similar to the ''Nassau''-class, but had a higher-calibre main battery of twelve 12-inch (305 mm) guns in six twin-turrets.<ref name=":0" /> The ''Helgoland'' also carried numerous 5.9-inch (150 mm) guns and 88 mm guns in casemate mountings.<ref name=":0" /> She later gained four 88 mm high-angle anti-aircraft weapons, but this is not reflected in the game. As a result, the 1911 ''Helgoland'' didn't have any anti-aircraft protection. Finally, the ''Helgoland'' carried six 50 cm torpedo tubes mounted underneath the waterline.<ref name=":0" />

The ''Helgoland'' was laid down in November of 1908, named after the Heligoland archipelago in the North Sea.<ref name=":1" /> She was launched in September of 1909. She was completed and commissioned on August 23rd 1911, after the completion of three years of construction.<ref name=":0" />

=== Operational history ===
The Helgoland entered service with the German 1st Battle Squadron, which formed the core of the German battleship strike force.<ref name=":1" /> She participated in some training exercises before the war, along with her sister ships. After the start of the First World War, Helgoland saw her first combat action at the Raid on Scarborough, Hartlepool, and Whitby. Due to heavy fog, the British and German forces never directly engaged despite the fact that ''Helgoland'' was at one point just 10 nautical miles away from the British fleet. ''Helgoland'' later participated in the Battle of the Gulf of Riga, though she failed to see major combat action.

''Helgoland'' participated in the Battle of Jutland, where she was located at the centre of the German battleship line. As a result, she saw less action than ships at the front of the formation, such as the battleship ''Konig''. Despite this, ''Helgoland'' still fired 63 12-inch shells, and took a hit from a 15-inch shell that caused a moderate amount of flooding.<ref name=":0" /><ref name=":1" /> The battle of Jutland was a tactical victory for the German fleet, having lost less ships and men than the British. However, it was a strategic victory for the British as the German grand fleet would never set sail in large numbers again.<ref name=":0" /><ref name=":1" />

''Helgoland'', along with her sister ships, were docked at Wilhelmshaven until the end of the war; she was supposed to participate in the suicidal German raid against the British fleet, in an attempt to secure better surrendering conditions.<ref name=":1" /> However, this failed as the sailors manning the ship mutinied.<ref name=":1" /> Thus, ''Helgoland'' was handed to the British as a war reparation, along with her three sister ships. She was eventually scrapped by 1924.<ref name=":1" />
