99A主战坦克是我国在的基础上研制的全新主战坦克，于2015年9月3日，在抗战胜利70周年阅兵式中亮相。下面从以下几个方面详细介绍。

　　The 99A main battle tank is a brand new main battle tank developed by China based on the foundation of the Anti Japanese War. It made its debut on September 3, 2015, during the 70th anniversary parade of the victory of the Anti Japanese War. Below, we will provide a detailed introduction from the following aspects.

　　一、战斗全重

　　1、 Battle heavy

　　99A主战坦克的战斗全重为55吨。

　　The combat weight of the 99A main battle tank is 55 tons.

　　二、动力系统

　　2、 Power system

　　99A主战坦克的动力系统设计上模仿了西方思想，采用集发动机和变速箱于一体的动力包设计。动力包的优点是可以进行整体的快速拆卸，提高维护便利性。但是，由于基础工业水平的限制，其发动机技术水平略不如西方，存在功率密度小、体积偏大、可靠性差的问题。

　　The power system design of the 99A main battle tank imitates Western ideas, adopting a power pack design that integrates the engine and gearbox. The advantage of the power pack is that it can be quickly disassembled as a whole, improving maintenance convenience. However, due to the limitations of the basic industrial level, its engine technology level is slightly inferior to that of the West, with problems such as low power density, large volume, and poor reliability.

　　三、武器系统

　　3、 Weapon system

　　99A主战坦克的主要武器是一门48倍径的125毫米滑膛炮，可以发射尾翼稳定脱壳穿甲弹和炮射导弹。其穿深达到700毫米，能有效击穿周边主战坦克的正面装甲。

　　The main weapon of the 99A main battle tank is a 48 caliber 125mm smoothbore gun, which can fire tail stabilized armor piercing shells and cannon fired missiles. Its maximum penetration depth reaches 700 millimeters, which can effectively penetrate the frontal armor of surrounding countries' main battle tanks.

　　四、防护能力

　　4、 Protective capability

　　99A坦克的正面防护能力出色，采用了模块式复合装甲，物理厚度超过1米，正面抗穿能力超过700毫米，抗破能力超过1000毫米。然而，侧面防护是其弱点，车体侧面防护仅为50毫米厚的钢板和一块橡胶裙板，小口径机关炮就能击穿。尽管炮塔侧面的装甲厚度有所保障，但仍然无法抵御反坦克火箭弹的攻击。

　　The 99A tank has excellent frontal protection capabilities, using modular composite armor with a physical thickness of over 1 meter, frontal penetration resistance of over 700 millimeters, and damage resistance of over 1000 millimeters. However, side protection is its weakness, as the vehicle's side protection is only 50 millimeters thick steel plate and a rubber skirt, which can be penetrated by a small caliber machine gun. Although the armor thickness on the side of the turret is guaranteed, it still cannot resist the attack of anti tank rockets.

　　五、信息技术99A主战坦克

　　5、 Information Technology 99A Main Battle Tank

　　是我国台信息化坦克，实现了战场态势共享、协同攻防、状态监测、系统重构等功能。在硬件和元器件方面，全部实现了自主可控。

　　It is the first informationized tank in China, which has achieved functions such as battlefield situation sharing, collaborative attack and defense, status monitoring, and system reconstruction. In terms of hardware and components, all have achieved autonomous controllability.

　　总的来说，是我国陆军装甲力量的重要组成部分，具有的火力、防护和机动性能。作为信息化的代表，在信息采集、传输、处理、显示与综合等方面也具有显著的优势。

　　Overall, it is an important component of China's army armored forces, with excellent firepower, protection, and mobility. As a representative of informatization, it also has significant advantages in information collection, transmission, processing, display, and synthesis.
