The Early Period Of The National Government Of Nanjing The Navy Added Major Ship Research

In the late Qing Dynasty,the Beiyang Navy experienced strength and decline,and the Sino-Japanese Battle severely damaged the foundation of Chinese naval construction.At the beginning of the 20 th century,the leadership system of China’s navy was in disorder,the training of naval personnel was poor,ships and weapons were outdated and backward,and the gap between the comprehensive strength of China’s navy and the advanced level of the world was widening.It was not until 1927,when the Nanjing Nationalist Government was established,that the Chinese navy began to unify.In 1929,the naval Department of Nanjing Nationalist Government was established,and the Chinese navy completed formal unification.The development of the Chinese Navy is becoming more formal.Naval ships are updated and strengthened through purchase and repair.In the early period of Nanjing Nationalist Government(1927-1937),the achievements of Chinese naval ship construction provided some help for the early Anti-Japanese War and the Yangtze River Valley operations,so it is of great significance for the study of naval ship history and the history of Anti-Japanese War.Naval ships are the key factors to maintain the safety of coastal defense and determine the success or failure of naval battles.The technical parameters of naval ships are directly related to the combat effectiveness of the fleet.The main content of naval ship construction is to repair and improve the hull of naval ships and the corresponding armaments.This thesis takes "the early period of the Nanjing Nationalist Government" as the time limit and "the navy added major ships" as the research object.From the perspective of science and technology history,this thesis adheres to the principle of historical development and focuses on the two technical directions of naval ship technical parameters and weapon equipment technology improvement.This thesis makes a special analysis and discussion on the naval warship acquisition plan in the early period of Nanjing Nationalist Government,the technical status of the newly added main ships and the combat effect of the ships.First,the background of naval ship acquisition in the early period of Nanjing Nationalist Government is studied.Firstly,the feasibility analysis and research of the multi-version naval ship acquisition plan left by the Nanjing National Government are carried out to explore its real implementation plan.Secondly,it focuses on the implementation of its warship acquisition plan and the construction of corresponding supporting facilities,in order to restore its historical appearance.Second,in-depth study of the navy in the early period of Nanjing Nationalist government to add major ships technology.Taking the technical parameters of naval ships as the main reference standard,the naval ships are equipped with weapons and equipment,and their technical level is objectively analyzed under their specific historical environment.Thirdly,following the course of history,the combat performance of the newly added main ships in the Yangtze River Basin in the early stage of the Anti-Japanese War is described in depth.Through the command of "people" to "objects",navy ships play the maximum role.In order to evaluate its impact on the battlefield,society and history from a more comprehensive perspective.Fourthly,through the comparison of naval vessel strength between China and Japan on the eve of the Sino-Japanese War and the eve of the Anti-Japanese War,the author draws the conclusion based on the comparative study and the reflection on the repeated construction,repeated battles and repeated failures of the Chinese navy in modern times.Through the research of this thesis,the technical level and historical significance of the new main ships of the navy in the early period of the Nanjing Nationalist Government are clearly presented,and it provides useful reference for the study of the history of modern naval ships and the history of the Anti-Japanese War.
