Tiger belonged to the 1911-1912 programme, while Queen Elizabeth belonged to the 1912-1913 programme. Tiger was laid down in June 1912 and Queen Elizabeth in October. Queen Elizabeth was launched in October 1913, ahead of Tiger in December. Tiger entered service in October 1914, while Queen Elizabeth followed in December because her advanced fire control and new 15-inch guns required longer trials. Their overlapping construction sets the timing constraint for the hypothetical redesign.
