HMS Indefatigable

1911 BATTLE OF JUTLAND WORLD WAR 1

The tireless history of HMS

Battlecruisers were designed as capital ships in the early 20th century. Her equipment is comparable to a battleship, but the reduced armor scheme (to increase cruising speed) makes her similar to a cruiser battleship.

Thus, the "battlecruiser" classification was born, with many global naval services at one time using some form of warship in the early 20th century.

HMS Indefatigable is a battlecruiser of the Royal Navy (RN). She was commissioned under the Naval Program 1908-1909 and awarded to Devonport Dockyard. Her construction began on February 23, 1909, and was launched in October of the same year.

On February 24, 1911, she was officially commissioned as HMS Indefatigable - a name meaning "to persevere with perseverance".

At the time of construction, the vessel displaces 18,500 long tons under standard load and up to 22,130 long tons under full load. Dimensions include a length of 590 feet, a beam of 80 feet and a draft of 29.8 feet. Power comes from 31 coal-fired Babcock & Wilcox boilers providing 43,000 hp on 4 shafts to 2 direct-drive Parsons steam turbine sets.

It has a top speed of 25 knots and a range of 7,000 nautical miles.

Her profile is conventional, with two main masts and two fuselage superstructures, one forward and one rear. Three funnels are located near the midship, two of which are paired with the forward superstructure. Four main towers are arranged around the main deck, one forward and one aft, with the remaining two offset near the midship.

Internally, she carried a crew of 800, although in wartime this could have increased by as many as 200. Armor varies from 6 inches on the belt and 2.5 inches on the deck to 7 inches on the turret and 10 inches on the conning tower.

The armament is spearheaded by 4 x 12" BL Mk X main guns mounted on four main twin gun turrets. This is supported by 16 x 4" Mk VII guns mounted on single gun mounts. 2 x 17.72 inch torpedo tubes are placed underwater along the side of the ship.

HMS Indefatigable is the lead ship of the Indefatigable class, consisting of three ships in total. They are an extension of the pre-1908 Invincible class (also three figures), but larger in size and thus increased internal volume and external displacement.

Armor was improved, and the longer length allowed the midship's main turrets to be repositioned, allowing these guns to attack from both sides through well-placed gaps in the side profiles. A common limitation of similar designs (without this clearance) is that the side guns cannot be used for flanking attacks.

When World War II hit Europe in the summer of 1914, HMS Indefatigable found itself in the Mediterranean as part of the 2nd Battlecruiser Squadron. The ship failed to overtake SMS Goeben and SMS Breslau on its way into Ottoman waters, but fighting broke out in the Dardanelles in early November when her artillery bombed Ottoman positions. Her career only lasted until May 31, 1916, when she was killed at the Battle of Jutland - the largest naval battle of the First World War.

The HMS Indefatigable received a direct hit from enemy fire from the rear turret and began to direct water to port, strikingly. A more direct strike targeted her forward cabin, eventually setting a few newsstands on fire.

Crippled, submerged and set on fire, the battleship soon sank with only two survivors of the wartime's 1,019 crew - a horrific end for a mighty warship.
