Talk about the vehicle's armour. Note the most well-defended and most vulnerable zones, e.g. the ammo magazine. Evaluate the composition of components and assemblies responsible for movement and manoeuvrability. Evaluate the survivability of the primary and secondary armaments separately. Don't forget to mention the size of the crew, which plays an important role in fleet mechanics. Save tips on preserving survivability for the "Usage in battles" section. If necessary, use a graphical template to show the most well-protected or most vulnerable points in the armour.

Scout plane

Located aft is a catapult with one E7K2 scout plane which provides unique offensive and defensive abilities, expanding tactical options. Ship-launched scout planes fly just like regular tree units but lack munition choices and cockpit views. The E7K2 is equipped with only defensive machine gun turrets (ventral as well as dorsal) but it does carry 4 x 60 kg bombs. It also has the scout plane ability to cap zones and lay down smoke cover (up to 3 times). Captains will be wise to remember to utilise the aircraft and consider when best to use it, for example to cap a point early or late in the match, to create a smoke screen to stymie enemy bombardment and repair, to attack enemy units directly, or perhaps something completely new! Carrying a heavier bomb load than most other scout planes, this unit has a very good chance to sink enemy boats or even a destroyer.

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:

• Fast
• Turrets are placed along whole ship which makes them hard to disable
• SAPBC ammo have very good penetration values
• 16 long range torpedoes (with torpedo modification)
• One scout plane.

Cons:

• Low crew amount for its size
• Almost all of her crew compartments were located on the deck, making them extremely vulnerable to HE shells
• Mediocre AA armament
• Can't release all torpedoes to one side

History

IJN Sendai, date unknown. Note the seaplane and catapult mounted above her rear guns.

IJN Sendai was the lead ship of the Sendai class, a class of three light cruisers built for the Imperial Japanese Navy following the end of World War 1. Designed to serve as leaders of destroyer flotillas, the ships were built in the early 1920s. Sendai saw service during the second Sino-Japanese war, and later served as the flagship of Destroyer Squadron 3 during the Second World War. She participated in numerous conflicts including the Battles of Guadalcanal, and was sunk during the Battle of Empress Augusta bay, having been critically damaged by American light cruisers.

Design and development

The Sendai-class cruisers were a class of three light cruisers, built as a follow-up to the previous Nagara class. As destroyer flotilla flagships, they were essentially enlarged destroyers, and displaced just 5,500 tons full. Sendai was armed with seven 140 mm (5.5 inch) guns, mounted in single mounts. The turrets were mounted in an unusual arrangement, with two guns fore, two guns on either side of the bridge, and three guns aft. Sendai's secondary and anti-aircraft suite was extremely sparse, with several 25 mm and 13.2 mm guns. Sendai, similar to the previous Nagara class, carried sixteen 610 mm "Long Lance" torpedoes, with four dual launchers and eight reloads. Her top speed was 35.6 knots, extremely fast for a cruiser - this allowed Sendai to maintain speed with the destroyers that she would command. She was also able to carry a reconnaissance seaplane, being fitted with a catapult and seaplane recovery facilities.

Sendai was ordered in the early 1920s, and completed by April 1924. Before the outbreak of war, she served extensively in the East China Sea, and participated in the second Sino-Japanese war.

World War II Service

Following the outbreak of the Second World War, Sendai served as the flagship of Destroyer Squadron 3. At the time of the Pearl Harbour attack, she was escorting troops to the invasion of Malaya. Sendai covered troop landings for most of early 1942, and later served as part of the main fleet cover during the attack on Midway.

In July of 1942, Sendai attacked American troops landing at Guadalcanal; she participated in both of the battles of Guadalcanal. During the second battle, she was shelled by the battleship USS Washington, but survived without damage. In March of 1943, Sendai was reassigned to the eight fleet as an escort; during her time there, the fleet was repeatedly attacked by American aircraft. She survived these attacks unscathed. However, Sendai ultimately met her demise at the Battle of Empress Augusta bay, where the Japanese force (composed of cruisers Myoko, Haguro, Agano and herself, as well as several destroyers) were attacked by the American cruisers Cleveland, Columbia, Montpellier and Denver, along with several destroyers of their own. Hit by concentrated fire from all four American cruisers, she sank with the loss of 184 crew members; the remaining 230 were rescued by her escorts.

The Sendai-class of light cruisers were a further development of the preceding Nagara-class, which itself was the successor to the Kuma-class. All ships of these classes were part of the Japanese 5,500 ton light cruiser design conceived in the years following WWI, with the Sendai-class being planned as the final ships to be based on this design.

To this extent, initial plans foresaw the construction of 8 vessels of the Sendai-class, however, with the signing of the Washington Naval Treaty in 1922, Japan was forced to cut back on these plans. This resulted in 4 ships being cancelled and one being broken up on the slipway, while the remaining ships did in fact see completion.

Sendai, as the lead ship of her class, was laid down in February 1922 and saw completion in April 1924. With the outbreak of hostilities in Asia in the late 1930s, Sendai took part in the Second Sino-Japanese War, participating in the Battle of Shanghai and providing support for Japanese land units.

During WWII, Sendai's early war service mostly consisted of escorting convoys around Malaya and Indochina while the ship also formally took part in the Battle of Midway, though not actively engaging Allied forces.

Sendai saw the height of her service career during the Solomon Islands campaign, taking part in both naval battles for Guadalcanal. Roughly a year later, in November 1943, Sendai was involved in the major naval battle of Empress Augusta Bay. There, Sendai would meet her fate, being heavily damaged by concentrated gunfire from four US cruisers, sinking on the following day on 3rd November, 1943.
