In the past 10 years, in order to develop and build a strong navy, the Han government has made great efforts in selecting the mother type, negotiating, signing contracts and ensuring the quality of construction, and has sent military technicians to Germany, Austria and other countries to study and train, and to participate in construction practice, so as to make relevant knowledge and technical reserves for the independent construction, repair and maintenance of warships in the future, and at the same time send naval officers to the German Navy and shipyards for training, internship and supervision, and sum up experience and lessons from them to ensure that the Chaoyang-class warships can form combat effectiveness as soon as possible. The characters and deeds who have made great efforts, sacrifices and dedication to the cause of the Navy in the past ten years should be remembered forever by the people of the Han Kingdom!
