Not entirely certain how credible or reliable the information in this article is, but posting it here nonetheless. The 105mm rifled gun is apparently based on the Royal Ordnance L7.
作为一款30吨级的轻量级坦克，ZTQ-15式浑身充满了欧式暴力美学元素。多项黑科技的运用让15式坦克充满科技范，堪称黄金战车。
可能世界上最好的105毫米坦克炮
15式轻坦装备一门源于英国的L7型105毫米线膛坦克炮，经过中国的不断改进，至今已经发展了三代产品。
这门105毫米坦克炮采用加长的轻量化身管，重量轻，射击精度高。能够发射全系列的105毫米坦克弹药。
珠海航展上北方工业展出的105和125坦克炮弹药，105脱壳穿甲弹长径比更大
105毫米整装弹，相比125毫米分装式结构，，脱壳穿甲弹能够采用更大的长径比设计，可谓是一分长一分强。在2017年的“装甲与反装甲日”的VT5型坦克性能展示中，厂方剧透该炮的穿甲威力达到的700毫米。要知道，俄罗斯的125坦克炮使用的3BM42钨芯穿甲弹垂直穿甲能力才500毫米左右。德国的Rh120-L55坦克炮的DM63穿甲能力刚好过700毫米。700毫米穿甲能力可能是使用特种弹的结果，但是这个威力已经足以跟三代主战坦克抗衡。
15式坦克还装备105毫米激光驾束制导炮射导弹，能够在5000米的距离绝杀对手。
15式坦克装备遥控武器站，配备35毫米自动榴弹发射器和12.7毫米机枪，让炮长在车内看着显示器轻松秒杀接近的步兵。
15式坦克是中国第一种实现尾舱自动装填的坦克，装弹机存弹18发，采用隔舱化设计，弹药殉爆时通过泄爆避免对乘员的伤害。自动装弹机能够以7～9发/分的速度装弹，可靠性和安全性都比俄式的圆盘装弹机好。
软硬兼施的铁布衫功夫
15式坦克采用钢基甲加复合装甲块作为基础防护，正面装甲厚度大，三代反应甲加成，对付破甲弹防护将不低于800毫米水平，足以对付120毫米口径的破甲弹。
VT5外贸坦克的能够抗击2代坦克的脱壳穿甲弹攻击，这相当于300～350毫米水平，考虑到外贸降低了指标，作为自用的15式正面抗穿能力估计不会低于400毫米。
15式侧面采用格栅和大间隙装甲，炮塔后面采用间歇装甲外挂复合装甲板，有效防止破甲弹攻击，炮塔顶部的覆盖复合甲增强顶部防护能力。坦克标准重量33吨(按照VT5指标推算)，可增加到36吨的高防护状态。
中国新型主动防御系统也将出现在国产坦克上，防护能力更上一层楼，对反坦克导弹和火箭弹全面免疫。
除了装甲硬防护，轻坦还配置定位精度更高的激光全向告警，配合烟雾弹发射器、热烟雾实现软防护。据相关技术资料透露，轻坦还将装备毫米波干扰设备用于对付末敏弹的探测。
一付强大的中国心
15式的新型132系列柴油机和自动变速的液力综合传动，让轻坦轻松达到70公里时速。132系列指标达到德国MTU880系列的技术水平，相比150系列，体积更小，表现更泼辣。与VT5使用的150发动机一样，15式的发动机也把功率调低到650kw，发动机的负荷降低。可靠性和耐用性更好。
这台高性能的发动机，让15式坦克在2017年青藏高原试验时实现了无忧驾驶，执行长距离不间断公路行军，不需要像以前通过汽车平板运输，全程履带行军，创造了中国坦克高原机动距离最长、行驶速度最快、故障最少多项纪录，得到部队的点赞。
15式注重人机环境，在国内坦克首次装备了空调系统和制氧设备。让坦克乘员在炎炎夏日告别桑拿。也不用怕高原反应。
世界一流的火控系统
公开展出的更新型的炮长瞄准镜，采用了图像显示器作为主瞄准界面，以后射击跟打游戏一样方便
15式轻坦的“猎-歼”型上反火控系统从99A发展而来，具有超强的环境感知能力，瞄准镜在行进间依然能提供非常稳定的图像。瞄准操作高度自动化，炮长只需要按下自动跟踪就能完成跟踪瞄准，射击准确性比人工更高。
新型坦克的信息化水平极高，通过网络作战体系，把各个作战单元连接起来，实现信息共享。坦克乘员通过信息终端掌握战场态势，接受任务，与队友协同配合，全程掌握战场主动权，是作战能力倍增器。

As a 30-ton lightweight tank, the ZTQ-15 is full of European-style aesthetics. The use of a number of black technologies makes the 15-type tank a 'golden chariot'.
Probably the best 105mm tank gun in the world
The 15-type light-tank is equipped with a British L7 105mm wire-tank tank gun. After continuous improvement in China, it has developed three generations of products.
This 105mm tank gun features a long, lightweight body tube that is lightweight and has a high precision. Able to launch a full range of 105mm tank ammunition.
105 and 125 tank artillery ammunition exhibited by North Industries at Zhuhai Air Show, 105 shelling armor-piercing projectile has a larger aspect ratio
The 105mm self-contained projectile, compared to the 125mm split-type structure, can be designed with a larger aspect ratio design, which is a point and a point. In the performance of the VT5 tank performance of the "Armored and Anti-Armour Day" in 2017, the factory spoiled the 700 mm of the piercing power of the gun. It should be known that the vertical armor piercing capability of the 3BM42 tungsten armor piercing projectile used by the Russian 125 tank gun is only about 500 mm. Germany's Rh120-L55 tank gun has a DM63 armor-piercing capacity of just over 700 mm. The 700mm armor piercing ability may be the result of the use of special bombs, but this power is enough to compete with the three generations of main battle tanks.
The 15-type tank is also equipped with a 105mm laser-driven guided artillery-launched missile that can kill opponents at a distance of 5,000 meters.
The 15-type tank is equipped with a remote-controlled weapon station, equipped with a 35mm automatic grenade launcher and a 12.7mm machine gun, allowing the gunner to watch the display in the car and easily kill the approaching infantry.
The Type 15 tank is the first tank in China to realize the automatic loading of the tail tank. The loader has 18 rounds of bombs and is designed with a compartmentalized design. When the ammunition bursts, it will avoid damage to the occupants through venting. The automatic loader can be loaded at a speed of 7 to 9 rounds per minute, which is better than the Russian disc loader in reliability and safety.
Soft and hard iron cloth kungfu
The 15-type tank adopts steel base armor and composite armor block as the basic protection. The thickness of the front armor is large, and the three-generation reaction is added. The protection against the armor is not less than 800 mm, which is enough to deal with the 120 mm caliber armor.
The VT5 foreign trade tank can attack the 2nd generation tank's shelling armor-piercing projectile, which is equivalent to the 300-350mm level. Considering that the foreign trade has lowered the index, the 15-type frontal anti-wear ability for self-use is estimated to be no less than 400mm.
The 15 side is equipped with a grille and large clearance armor. The back of the turret is equipped with an intermittent armored external composite armor plate to effectively prevent the armor attack. The top of the turret is covered with a composite arm to enhance the top protection. The standard weight of the tank is 33 tons (calculated according to the VT5 indicator), which can be increased to 36 tons of high protection.
China's new active defense system will also appear on domestic tanks, and its protection capability will be further improved, and it will be fully immune to anti-tank missiles and rockets.
In addition to armored hard protection, Lighttan also configures laser omnidirectional warning with higher positioning accuracy, and soft protection with smoke bomb emitters and hot smoke. According to relevant technical data, Lighttan will also be equipped with millimeter-wave interference equipment to deal with the detection of the terminal sensitive bomb.
A strong Chinese heart
The 15-type new 132 series diesel engine and automatic variable speed hydraulic integrated transmission make it easy to reach 70 km/h. The 132 series of indicators reached the technical level of the German MTU880 series, which is smaller and more pungent than the 150 series. Like the 150 engine used in the VT5, the 15-type engine also reduces the power to 650kw and the engine load is reduced. Reliability and durability are better.
This high-performance engine allows the 15-type tank to achieve worry-free driving during the 2017 Qinghai-Tibet Plateau test. It performs long-distance uninterrupted road marching. It does not need to be transported through the flat plate of the car, and it has created a Chinese tank plateau. The maneuvering distance is the longest, the driving speed is the fastest, and the fault is at least a number of records, which is praised by the troops.
The 15th style focuses on the human-machine environment, and the domestic tanks are equipped with air-conditioning systems and oxygen-making equipment for the first time. Let the tank crew say goodbye to the sauna on a hot summer day. Don't be afraid of altitude sickness.
World-class fire control system
The 15-style "hunting-歼" type anti-fire control system developed from the 99A has a strong environmental sensing capability, and the scope can still provide a very stable image during the journey. The aiming operation is highly automated, and the gunner only needs to press the automatic tracking to complete the tracking and aiming, and the shooting accuracy is higher than the manual.
Commander's sight with large displays. Aiming is as convenient as playing video game.
The information level of the new tanks is extremely high. Through the network warfare system, the various combat units are connected to realize information sharing. The tank occupants grasp the battlefield situation through the information terminal, accept the mission, cooperate with the teammates, and master the battlefield initiative right throughout the battle, which is the combat capability multiplier.
