Cheetah self-propelled anti-aircraft gun, is the body of the Leopard 1 main battle tank plus anti-aircraft turret, the turret is equipped with 2 35 mm caliber anti-aircraft guns to form a type of weapon to deal with low-altitude targets, the chassis and other hardware equipment are modified to adapt to the new turret, and other imported Cheetah countries have also developed their own anti-aircraft guns on this basis.
The basic parameters of the Cheetah self-propelled anti-aircraft gun are 7.68 meters long, 3.71 meters wide and the total weight of the vehicle is 47 tons. The crew consists of 3 people and is powered by a 66 kW 4-cylinder diesel engine of Daimler-Benz, with a maximum driving speed of 65 km/h, a maximum mileage of 550 km and a wading depth of 1.2 m.
The main equipment is two KDA-L/R04 35 mm anti-aircraft guns, with an effective range of 4000 meters, an effective firing height of 3000 meters, a muzzle initial velocity of 1,175 m/s, a limit rate of fire of 550 rounds per minute, a reserve of 620 rounds, a single shot hit rate of 15%, and a body tube life of 2500 rounds to 3000 rounds.
Thanks to the excellent redundancy of the 35 mm large-caliber ammunition type, the adaptable ammunition is composed of incendiary grenades, tracer incendiary grenades, armor-piercing incendiary explosives, tracer armor-piercing incendiary explosives, etc., with bottom electronic fuze grenades and warhead mechanical fuzes.
The ammunition base of the Cheetah self-propelled anti-aircraft gun is 640 rounds, of which 600 rounds are loaded inside the turret to load the fragmented ammunition of the near-explosion fuze, mainly for air combat guided by radar, and 40 rounds are stored in the outer magazines on both sides of the turret to load armor-piercing shells and anti-personnel grenades, mainly for attacking ground personnel and lightly armored targets guided by optical sights.
This type of equipment is also quite a threat to heavy armored targets such as main battle tanks, and the rain of bullets that come to the surface will easily cover the tank's sighting system, so that the tank loses the ability to observe the battlefield situational awareness, and the fleet with weak will to fight will easily abandon the vehicle and leave.
The rear of the turret is equipped with a Siemens MPDR-12 fully coherent pulse Doppler system air-to-air search radar, the working frequency band is S-band, the maximum range is 15 km, the antenna speed is 60 revolutions / min, 360 ° omnidirectional search between stop and travel, and the system reaction time is 6-8 seconds.
The front of the turret is equipped with a single-pulse Doppler system target tracking radar developed by Siemens Alps, with a range of 15 kilometers, and two periscope optical sights are also installed on the turret, one for the commander and one for the gunner, and with a stable gyroscope, the scope has a shooting rate of 1.5 times against the air and 6 times the rate of ground fire.
Cheetah self-propelled anti-aircraft gun unit price of 4.4 million US dollars, far more than the most advanced tank at that time Leopard II main battle tank, such a design of course can not be used up to retire, the German military followed up to the Cheetah carried out a large number of modern modifications, follow-up can launch AHEAD intelligent ammunition anti-air capabilities greatly improved, but also installed on both sides of the turret two Stinger portable air defense missiles, the formation of a simple Cheetah shell gun integration system, also known as Cheetah 1A2 type.
Cheetah's integrated fire control system is also quite powerful, using a digital fire control computer, the commander of the self-propelled anti-aircraft gun, the gun commander control panel uses a display, there is an auxiliary computer in the turret, after the main engine problem can still continue to run for the anti-aircraft gun to correct the ballistic trajectory, but also has a set of friend or foe identification system connected, it can automatically identify the enemy and fire.
Although it has withdrawn from front-line service, Cheetah's manufacturer, Klaus-Marfy Wiggmann, still has 50 and 23,000 rounds of ammunition in stock, and these old self-propelled anti-aircraft guns and shells will be sent to the Ukrainian army, which is another type of inventory weapon after Rheinmetall's request to the German government to export 88 Leopard 1A5 main battle tanks and 100 second-hand "Weasel" infantry fighting vehicles to Ukraine.
At present, the Brazilian military has denied the provision of 35mm self-propelled anti-aircraft ammunition and its spare parts for Ukraine, and Switzerland has also refused to transfer the ammunition equipped with German weapons to Ukraine on the 25th, and 20,000 rounds of ammunition are just like playing in front of thousands of self-propelled anti-aircraft guns that can be fired out in a minute at every turn.
All information source network and netizens guess that there may be discrepancies with real data, sorting out is not easy to ask the audience here for a free attention and like, everyone wants to see what the country's weapons and equipment and military strength, you can private message or leave a message in the comment area to order, I will reply to everyone, thank you for kowtowing to everyone.
