[edit] Naval Hero Thesis
This was grounded in Jominian thought and later had its successor in Mahan. The basic idea was that the superiority of the leader and of the morale of the unit would break the back of the enemy and defeat her. Mahan theory was much more complex and held seeds to modern geopolitical though refind by McKinder.

[edit] Decisive Firepower Doctrine
With the advent of the modern all-big-gun battleship, not surprisingly many admirals focussed on the importance of concentrating as many such battleships together in a single main fleet as possible, with the objective of seeking out the enemy's main fleet and engaging them in a single decisive battle. In this view, the vital point of battle was to have the most and largest main armament, in order to batter the opposition into submission.

[edit] Naval Firepower Doctrine
While a focus on winning the decisive naval battle was important, it was also considered valuable to use a variety of weaponry in order to achieve victory, in addition to the main armament of capital ships. Lighter warships were also important, as they could dart in and launch deadly torpedo attacks, while secondary armament was necessary to defend against these attacks. A balanced fleet of both capital and escort ships was essential to victory in modern naval combat.

[edit] Fleet Auxiliary CV Doctrine
Even after the first aircraft carriers were completed, the focus remained on surface combat between capital ships. The role of carriers was limited to supporting engagements between capital ships, such as aerial reconnaissance and attacking damaged enemy warships after battle, as opposed to seeking out battle on their own.

[edit] Fleet Auxiliary SS Doctrine
Early submarine use centred around supporting combat operations by surface ships, as opposed to sortieing on their own to attack enemy shipping. For example, a squadron might be despatched to engage an enemy squadron, and while acting as if they are retreating, attempt to draw the enemy squadron into an area containing pre-positioned submarines so that the submarines could launch torpedo attacks on the unsuspecting enemy.

[edit] Convoy Sailing
Traditionally in wartime, merchant shipping had continued to sail individually and without escort, in the belief that the most effective way of defending merchant shipping was through the use of squadrons hunting down enemy raiders. However, with the proliferation of enemy raiders, and the rise of the submarine, it became increasingly clear that having merchant ships sail together would make them much easer to defend with escorts.

[edit] Integrated Naval Doctrine
The proliferation of new warships like the aircraft carrier and the submarine required modern navies to increasingly focus on which approach they would take to naval warfare. The Fleet-in-Being school argued in favour of defending sea lanes using traditional surface warships, while the Base Strike school took a more offensive approach, emphasizing the role of carriers, and the Sealane Interdiction school argued for attacking enemy sealanes with surface raiders and submarines.

[edit] Advanced Destroyers
The evolution of the submarine into a potent threat to warships and merchant ships alike resulted in the evolution of destroyers to assume the primary role for defending against them, as opposed to their former role of defending the main battle fleet from torpedo boats. Thus the first years after the First World War saw improvements in destroyer design that aimed to enhance their ability to find and sink submarines, such as the implementation and refinement of SONAR.
