2:1 Plan
The 2:1 Plan, also referred to as the Vandarch First Policy, was a maritime strategic policy and planning effort initiated by the Kingdom of the Fhainn in 1878. It was a counter to an opposing school of thought focused on an open seas navy, the Tri-Oceanic Plan, which rose in response to the question of how to best handle the issue of split naval development between the calmer inland sea of the Vandarch and the tradebearing and foreign-dominated high seas.
The 2:1 Plan called for at least two-thirds of the navy to be built in the Vandarch Sea in order to ensure Fhainnin naval dominance in the Vandarch, which was considered more critical than challenging a peer competitor on the open ocean due to Faneria's geopolitical and industrial core being situated directly along its coast. The 2:1 Plan became the dominant school of thought in the Crown Navy after construction began on the Carolina-Grand Canal, which risked introducing Burgundine and Urcean naval might to the area and quickly overwhelming the Fhainnin shipyards' ability to expand or replace fleet assets on short notice.
The policy is directly responsible for the inability of the Fhainnin Navy to deploy effectively against the Fiannrian Navy during the Fourth Kin War and altered the direction of Fhainnin ship design significantly towards bow configurations meant for the Vandarch Sea. These bows worked well in calm waters but undermined speed markedly in rough ocean weather; fixing these issues for the Outer Seas Fleet required doubling back on design and development and later parallel development for both the Inner and Outer fleets before shipyards in the Vandarch were retooled to build newer bow configurations.
The doctrine became obsolete with the opening of the Grand Vandarch Canal, though it was largely only practiced as a traditional guideline by Republican strategists after the Fhainnin Civil War.
