Df 21 Missile - Dong-Fg 21 (DF-21; NATO reporting name CSS-5 - Dong-Fg (simplified Chinese: 东风; traditional Chinese: 東風; lit. 'East Wind') is a two-stage rocket developed by Dong. Changfg Mechanics and the Academy of Electronics Technology. Development of the Fg-series medium-range ballistic missile (MRBM) began in the late 1960s and was completed around 1985-86, but was not deployed until 1991. The JL-1 submarine-launched missile was China's first land-fueled missile. In 2008, The US Department of Defense estimated that China had 60-80 missiles and 60 launchers.
Originally developed as a strategic weapon, later variants of the DF-21 were designed for nuclear and conventional missions. It is very explosive; It is believed to be capable of carrying munitions or a 300kt nuclear warhead. The latest DF-21D is the world's first ballistic missile (ASBM). The DF-21 was developed as a space-mounted anti-satellite weapon/anti-missile weapon carrier.
Df 21 Missile
Although the launcher itself is mobile, to minimize vulnerability, a true launch unit would require support vehicles to cover an area of 300 × 300 meters, making quick and easy detection difficult. Additionally, the Wheeled Launcher was not designed for off-road travel, requiring strong ground fire to avoid back-end blast and debris damage from the force of the shot, limiting its range of fire to roads and pre-launched launches.

600 kg (1,300 lb) 500 kt nuclear warhead with an estimated circular error probability (CEP) of 300~400 m; This version does not apply to operational service.
The missile is the first of two capabilities that can be equipped with a nuclear or conventional warhead. In 2010, the DF-21C was deployed in western China.
It is an anti-ship ballistic missile with a maximum range of 1,450 km (900 mi; 780 nmi) according to the US National Air and Space Intelligce Cter. Intelligce Cter was not thought to be deployed in 2009.
As more UAVs and satellites are added, the navigation system is considered to be in an evolutionary process.

The US Department of Defense said in 2010 that China had developed and fielded an initial operational capability (IOC).
An anti-ship ballistic missile based on the DF-21; It's a long shot; It is the first ASBM and weapon system capable of targeting a moving aircraft carrier from land-based mobile launchers.
The DF-21D is to use maneuverable recovery vehicles (MaRVs) with a terminal guidance system. One such missile was tested in 2005-6 with the launch of the Jianbing-5/YaoGan-1 and Jianbing-6/YaoGan-2 satellites, which would provide Chinese targeting information and sighting SAR (synthetic aperture radar). respectively These innovations strengthen China's ability to prevent US airlines from operating in the Taiwan Strait.
In January 2013 they conducted a missile test against a target in the Gobi desert.

The DF-21D retest vehicle appears to resemble the American Pershing II RV, which was withdrawn from service in 1988. The Pershing II's RV weighed 1,400 lb (640 kg) and had four buttons to operate. After turning the atmosphere, a 25-G pull; At Mach 8 and th they moved 30 nmi (35 mi; 56 km) toward the target to climb into a terminal dive. Army missile training manuals are available on the Internet, and public source publications cover many. The DF-21 has comparable range and payload. Although the DF-21D does a lot of damage based on its speed and kinetic energy. The Australian Strategic Policy Institute estimates that the energy of a 500 kg (1,100 lb) inert is similar to an RV impacting at Mach 6. The power and explosive power of the US Harpoon anti-ship missile is a quarter that of the Russian Kh-22 hypersonic missile at 12,800 lb (5,800 kg); lb (1,000 kg) head.
In 2009, the US Naval Institute stated that if the theory worked, it would "currently... have no head defense capability against an aircraft carrier". In 2010, it was reported that China was finalizing development of a MaRV warhead for the DF-21.
The U.S. Navy has shifted its focus from a shallow-sea blockade ship blockade force to building deep-sea ballistic missile defense (BMD) destroyers.
The US has deployed most of its ballistic missile defense fleet to the Pacific, expanded its BMD program to all Aegis destroyers, and increased its purchase of SM-3 BMD missiles.

The United States also has an excellent network for tracking ballistic missile launches, giving fleets enough warning to move away from the target area while the missile is in flight.
Kinetic defense against the DF-21D will be difficult. The Navy's primary ballistic missile interceptor, the SM-3, is designed to intercept missiles during medium-range maneuvers in space, so they are ineffective and must be fired almost immediately before they can be retried or hit by an Aegis ship. positioned below its flight path. The SM-2 Block 4 can intercept air-to-air missiles, but will perform high-G maneuvers that make intercepting the warheads difficult.
In 2016, the US Navy was testing the SM-6, a terminal stage designed to intercept ballistic missiles.
In late 2013, a military analysis report on the Russian DF-21D concluded that the only way to successfully counter it was with electronic countermeasures. Interceptors aimed at bombing high-speed targets have been made before; The Russian report cited the 2008 interception of a malfunctioning satellite from a US cruise ship, but in that case the warship had full knowledge of its location and trajectory. A Mach 10 DF-21D would likely be used by the US Navy to prevent an attack without knowing the missile launch, with electronic countermeasures.

The use of the missile is a nuclear exchange; leading a regional arms race with India and Japan; INF Treaty between the People's Republic of China, the United States, and the Soviet Union d. Not a party.
At the time of the DF-21D's unveiling, some analysts said the "carrier-killer" missiles doomed their use on US aircraft carriers, saying they were too risky to take on a new weapon. But U.S. Army and Air Force military leaders don't see it as a "game changer" to count out carriers altogether.
First, a Missile cannot destroy its target alone.
Second, he has trouble finding his target. The DF-21D has a range of 1,035 to 1,726 miles (899 to 1,500 nmi; 1,666 to 2,778 km); Therefore, it is necessary to carry it through other means before starting. . Over-the-horizon radars cannot determine the exact location of the carrier and must be used in conjunction with China's new satellites. Although reconnaissance aircraft and submarines can also be used to locate the carrier, they are vulnerable to carrier attack group resistance.
China's Display Of Aerial Might Sends Message To Us
Finally, the DF-21D also has radar and optical ssors for tracking. A ship target moving at sea has not been tested at 55 km (30 kn; 34 mph). Countermeasures The missile's "kill chain" processes and continuously updates the carrier's location details; launch preparation; Information on programming and shooting is required. The US military's AirSea Battle concept involves breaking the chains of killing.
DF-21D is not as fast as theory. Ballistics can achieve Mach 8-15 at an altitude of 50 km (160,000 ft), but increase air resistance in the lower atmosphere region, reducing terminal velocity to 3-5 km (9). 800–16; 400 feet). Due to the ionization lock, the ship was unable to reach its target until then, leaving little time to actually find it. If it detects a target shortly before its terminal ssors hit, the target can leave the area and when it tries again, the slow speed makes it vulnerable to missile interception.
On September 3, 2015, the missile was put on public display in Beijing to mark the 70th anniversary of the end of World War II.
A DF-21D, along with a DF-26B, crashed on August 26, 2020, in the South China Sea between the Hainan and Paracel Islands, a day after China said it shot down a US U-2 spy plane. Its unauthorized no-fly zone during China's naval exercises on the northern coast of the Bohai Sea

It has blacklisted 24 Chinese companies and targeted individuals it says are involved in construction and military activities in the South China Sea.
US officials later assessed that the People's Liberation Army Rocket Force (PLARF) had fired four medium-range ballistic missiles.
The DF-26 has a range of 5,000 km (3,000 miles) of the DF-21.
