Construction and Acceptance

When in December 1906 Indomitable's anchor and hawsepipe arrangements seemed problematic in mock-up, Lusitania was fitting out in Clydebank, and it was observed that she had a more elegant plan. It was mimicked for Inflexible and Indomitable.[7]

Navigational Equipment

The ship was one of seven which tested Willis and Robinson Electric Revolution Telegraphs. Testing was completed in late 1913.[9]


In July 1914, the ship was appropriated 42-foot motor launch No. 261, though the boat was not yet delivered from the contractor.[10]


Indomitable received the first sea-going Service Mark II radio set, and conducted range tests to Vernon while on her voyage to Quebec in 1908.[11]

Sometime before 1913, she may have also had a Type 3 Battleship Auxiliary set, but it was to be replaced by a Type 10 Cruiser Auxiliary set.[12]

Main Battery

Indomitable incorporated new turret training engines controlled by a single wheel which proved a great advance over earlier equipment. The new gear showed "marked reduction in throw-off and good control of starting, stopping and creep with little effort on the handwheel.[13]



In 1913, Indomitable was slated as part of the seventeen ship order to receive a director. It was fitted after December, 1915 and shortly before the Battle of Jutland,[14] as her first-ever test firing with it occurred on 23 May, 1916 and – while a success – its newness prompted the choice to not employ it at Jutland.[15]


In late 1913, the ship landed a Pattern 740 Zeiss stereo spotting telescope Mark II at Portsmouth in order to take on a Ross Pattern 873 model for a three-month comparative evaluation.[16]


Dates of appointment are provided when known.


Indomitable recommissioned at Chatham on 21 February 1912.[29]

She recommissioned at Sheerness on 10 February, 1914.[30]
