Design

The Japanese were looking for a 19,000 ton ship that would carry 12" guns. This transformed into a 27,500 ton ship with 13.5" guns. However, the Japanese eventually wanted to have the largest gun on a warship so the 14" Vickers Mk I was selected.

The Kongo class battlecruisers were designed by Sir George Thurston as an improved Lion class ship. It was ordered under the 1920 Expansion Program and the 1911 Emergency Expansion Program. The IJN Kongo was build in Great Britain so that the Japanese could study its building techniques.

The IJN Kirishima was the first ship built by a private company in Japan.

The IJN Haruna / IJN Hiei had 31% of its materials were imported for assembly.

Aircraft

In September 1917 the IJN Kongo was modified to test launching of aircraft. It was a success and the rest of the Japanese capital ships received aircraft.

In the 1930s the aircraft used were Type 95 Model 11 Nakajima E8N1 "Dave" and Type 94 Kawanishi E7K1 "Alf."

Armament

The Kongo class was the first Japanese ships to carry 14" guns.

The Vickers Mk J fired a 1,485 lb shell 38,770 yards.

The Vickers 6" L/50 Mk M guns were mounted in casements. They could fire a 100 lb shell.

Engines

To attain the high speed that was wanted 36 boilers were to be placed in eight boiler rooms. They would exhaust into three unevenly spaced funnels.

London Naval Treaty of 1932

As a result of the first London Naval Treaty the IJN Hiei was demilitarized by the removing of its armor belt and reducing the boilers to reduce speed and weight.

Modernizations

The Kongo class were initially considered battlecruisers but after several Modernizations in the 1930s they were classified as fast battleships.

The hulls were lengthened 25'. Bulges were added. Horizontal armor was strengthened. The boilers became oil fired.

In 1936 the boilers were improved and the speed went from 26 to 30 knots.

A 10 cm rangefinder was added to the tops of the pagoda masts.

Usage

Indian Ocean

The IJN Kongo, IJN Haruna, IJN Hiei, and IJN Kirishima joined the IJN Akagi, IJN Kaga, IJN Hiryu, and IJN Soryu in the Indian Ocean to attack Allied merchant ships and interrupt supply lines.

The IJN Kongo and IJN Haruna, with the four ships of the 17th Destroyer Squadron, were sent to bombard Christmas Island on March 7, 1942.

C Operation

Large fleet of five carriers, the four Kongo class battlecruisers, and a covering force of cruisers and destroyers was led by Admiral Nagumo.

A Catalina saw the fleet on April 4, 1942, and was shot down after it reported in.

On April 5, 1942 the HMS Cornwall and HMS Dorsetshire were sunk south of Ceylon by carrier aircraft.

On April 9, 1942, a force of nine Blenheims attack and five were shot down.

Battle of Guadalcanal

On the night of October 13 - 14, 1942, IJN Kongo bombarded Henderson field with 430 14" rounds and the IJN Haruna fired 438 14" and 21 6" rounds.

On the night of November 12 - 13, 1942, the IJN Hiei, IJN Kirishima, a cruiser, and twelve destroyers were sent to bombard Henderson Field but were intercepted by TG67.4. The USS Atlanta and USS San Francisco were lost to a combination of gun fire and torpedoes. IJN Hiei was hit by 50 5" - 8" rounds from the USS Portland and USS San Francisco. The IJN Hiei was hit by four aircraft borne torpedoes on November 13, 1942. She was later scuttled by Japanese destroyers.
