What was the Washington Naval Conference?
The Washington Naval Conference, also known as the Washington Arms Conference, was a major international gathering that took place from November 11, 1921, to February 6, 1922. It was a naval arms limitation conference held in Washington, D.C., USA, where representatives from ten major naval powers gathered to discuss and negotiate limits on their naval armaments.
Background
The early 20th century was marked by a growing tension between the major naval powers, particularly the United States, Great Britain, Japan, France, and Italy. The sinking of the Lusitania and other passenger ships by Germany during World War I led to a surge in the construction of battleships, which in turn heightened tensions between the major powers.
Objectives
The primary objectives of the conference were to:
• Limit the construction of new battleships and other capital ships
• Reduce the size and tonnage of existing naval fleets
• Promote international cooperation and peace
• Prevent future naval wars
Signatories
The conference was attended by representatives from the following ten nations:
- United States
- Great Britain
- Japan
- France
- Italy
- Belgium
- China
- Netherlands
- Portugal
- Britain’s Dominion of Canada
Treaty Provisions
The conference resulted in the signing of the Washington Naval Treaty on February 6, 1922. The treaty contained the following provisions:
Battleship Limitations
• Capital Ship Ratio: The treaty established a 5:5:3 ratio of capital ships between the United States, Great Britain, and Japan, with France and Italy receiving lower ratios.
• Battle Cruiser Limitations: Battle cruisers were abolished, and their construction was banned.
• Gross Tonnage Limits: The total gross tonnage of capital ships was capped at 525,000 tons for the United States and Great Britain, and 315,000 tons for Japan.
Cruiser Limitations
• Cruiser-to-Battleship Ratio: The treaty set a ratio of 1 cruiser to 2 battleships for the United States and Great Britain, and 1 cruiser to 1.5 battleships for Japan.
• Light Cruiser Limitations: Light cruisers were limited to 6,000 tons each.
Submarine Limitations
• Submarine-to-Dreadnought Ratio: The treaty set a ratio of 1 submarine to 2 dreadnoughts.
• Submarine Gross Tonnage Limit: Submarines were limited to a gross tonnage of 1,000 tons each.
Air Power
The treaty did not place limits on air power, recognizing the rapid growth and potential of naval aviation.
Implementation
The Washington Naval Treaty came into effect on February 5, 1923. The treaty was widely hailed as a major achievement in naval disarmament and marked the beginning of a period of cooperation between the major naval powers.
Aftermath
The Washington Naval Treaty remained in effect until 1936, when it was replaced by the London Naval Treaty. The treaty had several significant consequences:
• Reduced naval expenditure: The treaty reduced the costs of naval armament, allowing countries to reallocate resources to other areas.
• Promoted international cooperation: The conference demonstrated the potential for cooperation and diplomacy in the realm of naval affairs.
• Encouraged the development of naval aviation: The treaty’s omission of air power limits helped stimulate the development of naval aviation.
Conclusion
The Washington Naval Conference and the subsequent Washington Naval Treaty were a significant milestone in international relations and naval affairs. The treaty’s limitations on capital ships, cruisers, and submarines marked a major step towards naval disarmament and helped prevent future naval wars.
