About the hatch cover of the 99 tank, the disadvantages of the Type 99 tank

The commander's tower is called the conning tower, and it can rotate 360°. In front of him is a variable magnification periscope surrounded by four non-magnification periscopes, which create a 360° panoramic view.

All of the periscopes are mounted on top of the conning tower, which is what you call the hatch, and rotate with the conning tower. Among them, the front 3 periscopes are installed in the front half of the conning tower, so the front half is fixed; And the rear 2 periscopes were mounted on the hatch cover.

In normal times, the main periscope in front uses a low magnification and a wide field of view, which is conducive to searching for targets. The commander can search the battlefield with a panoramic view formed by 5 periscopes; Once a target is spotted, the conning tower can be rotated so that the main periscope directly in front of it is aimed at the suspicious location, and then switch to a high magnification for a closer look (this is the purpose of the conning tower to rotate independently of the turret).

After confirming the enemy's situation through high-level observation. Use the reticle in the periscope to aim at the target and press down on the periscope handle"Adjust the gun button".At this point, the gunner's control of the main gun will be cut off and the commander will be at his disposal.

A coil is installed on the base of the tower, and when the tower rotates away from the position directly in front of the turret, the coil generates a voltage signal. When the commander presses"Adjust the gun button", this voltage signal is transmitted to the turret's electric steering machine, which then drives the turret. When the turret is pointing the same as the conning tower, the voltage signal is 0 and the turret stops rotating.

At this time, the main gun was aimed in the direction indicated by the commander.

The commander can release at this point"Adjust the gun button", to be aimed by the gunner. Because the commander's periscope did not mark the trajectory of the reticulation, it was impossible to measure the distance and adjust the angle of fire. The final shot was still in the hands of the gunner.

The old-fashioned 59 Tan is just like this"Fire control system".Modern commanders already have the ability to aim and shoot, and can personally manipulate the guns.

It was precisely because of the large number of periscopes installed in the front of the commander's conning tower that it was arranged to be opened backwards.

And the cannon commander's hatch is just a simple entrance, so there is no periscope. The gun commander's periscope cannot be rotated, only with the turret.

The commander had to operate an anti-aircraft machine gun, and it was difficult to shoot from the door forward.

The cannon door is still protected when it opens forward.

Soviet-style tanks routinely opened the doors as long as the anti-aircraft machine guns were not operated.

China's Type 99 tank is the latest main battle tank of our army, with excellent bulletproof appearance, its turret and hull are made of composite armor, the bullet resistance has been doubled, it is the main assault force of our army's armored division and machine infantry division, known as China's land trump card, known as Asia's first third-generation main battle tank.

The weakness of the 99 was that it was still a traditional tank, and it was too late in service, so it was impossible for him to equip the troops in large quantities. As for the mainstream of the 21st century upstairs, I can't agree with this, street fighting is just a last resort for the weak to deal with the strong, and it is very good to completely position your main equipment in street fighting.

First of all, many domestic bridges could not withstand such heavy tanks, and it was a little troublesome to excite transportation. There is also the fact that the Chinese's tanks have a strong Soviet-style style, that is, it is considered to fight a plain war in Pingchuan, not street fighting, but street fighting has become the mainstream in the 21st century! There is also the poor comfort of the interior.

Moreover, it has not experienced the test of actual combat!

Network: The United States has a network battlefield information system on the battlefield, between tanks and tanks, and between tanks and aircraft.

In the vernacular, 99 may appear on the battlefield 2 vehicles attack a vehicle at the same time, or a certain stronghold and be killed by the straight 9, the 99 tank will be unclear in a short period of time, and it is easy to repeat the phenomenon of repeated configuration and repeated attacks, and the tank with a network battlefield information system is like many pairs of eyes, everyone you see it, everyone sees it, and you see it, and the macro control ability of the battlefield will be improved.

As for the defense capability, now it is basically on paper, there is no actual combat experience, judging from the data on paper alone, it is about the same as other 3rd generation tanks in the world, and has an advantage over the Soviet, 72 80, etc., and individual indicators exceed 90

The Type 99 main battle tank is a new generation of main battle tank of the Chinese People's Liberation Army Army, mainly developed by the Second Research Institute of China North Industries Group and produced by China North Industries Corporation.

The Type 99 main battle tank appeared at the 2009 National Day parade and was the first phalanx of the armored phalanx, reflecting its important position in the PLA Army.
