Career

Main Armament

Orion was built with 13.5-inch Mk II mountings for her guns.[3]

Torpedoes

The ships had three 21-in submerged torpedo tubes. Orion's broadside tubes were angled at 90 degrees, unlike her sisters, whose were angled 10 degrees in advance of the beam.[4]

Alterations

In 1913, Orion was slated as part of the seventeen ship order to receive a director for her main battery. It was fitted sometime between May and December, 1915.[5] In 1915, it was also decided to outfit her 4-in battery with director firing as a test, as resources did not permit wholesale support of the ships with 4-in secondaries. However, this installation did not actually occur until mid-1918.[6] It seems that Orion was the only capital ship in the Royal Navy to have a director for a 4-in secondary battery.

In late 1914, it was decided that Orion should receive one of 22 Open Director Sights for her "Q" turret. It was fitted between April 1916 and June 1917.[7]
