When it comes to naval ballistic missiles, people will equate it with submarine-launched strategic missiles. However, India has a short-range ballistic missile launched by surface ships. The Indian Navy calls it Danush ship-to-surface ballistic missile, which is unique among the navies of the world today. What kind of missile is the weird Danush? Why is the Indian Navy equipped with such a strange missile system?
The so-called Dannush missile is actually the naval type of the Pritvi missile. The Chinese translation of Plitvi is Dadi. It was developed in 1983. It is a short-range tactical ballistic missile. It is mainly used to strike enemy targets in depth and has been heavily equipped with the Indian army. Pritvi missiles are currently family-based and include 3 models: Army type, SS-150, which can carry a 1 ton warhead and attack targets 150 kilometers away, mainly attacking tactical targets behind enemy lines; Air Force type is SS -250 type, can carry 500 kilograms of warhead, attack 250 kilometers of targets, mainly used to destroy the enemy's rear airport and logistics warehouse.

Navy type, namely Danush ship-to-surface ballistic missile, is the Indian Army Prithvi SS-150 A replica of the type ballistic missile, it can attack targets 150 kilometers away. It is mainly launched by Indian navy warships to attack the opposing naval base and other coastal targets. The three types of Prithvi ballistic missiles are all about 8 meters in length. It has a diameter of about 1 meter and weighs about 4 tons. It uses the same rocket engine.The payload and range are required to adjust the engine.
The biggest difference between the Danush missile and the Army and Air Force missiles is launching. Platform: Army and Air Force models use mobile launch vehicles modified from 20-ton trucks, while Danush uses a carrier-based stable launcher developed by the Indian Defense Research and Development Organization. The first test firing of the Danush missile was in April 2000The test fire was carried out from a warship moored in the Bay of Bengal, 20 kilometers away from the eastern Indian state of Orissa. Scientists from the Indian National Defense Research and Development Organization monitored the missile test firing process. Test photos from 2000 show that the missile was launched from a specially modified Sukanya-class patrol ship. A hydraulically stabilized orbital fixed platform was installed on the helicopter deck of the stern, turning the helicopter deck into A launch pad and two Danus missiles are placed in the helicopter library on the ship.
On January 29, 2002, India successfully fired again on its ship in the Cochin waters off the southern Kerala state. 2 Danush missiles. At present, the Indian Navy has decided to equip the Sukanya-class patrol ship and Krivak-class guided missile frigates. The navy-type Danush missile is like its army and air force brothers. The same, the appearance is also round and fat, the projectile is 8.56 meters long, and there are 4 large triangular wings in the middle of the projectile to correct the flight attitude. The outer shell is made of a light aluminum alloy material developed by India. Single-stage rocket engine It is filled with volatile liquid fuel, and the formula is nitric acid and triethylamine at a ratio of 1:1. The missile uses an inertial guidance system. During the flight, the ground can control the missile’s azimuth and flight attitude through a computer. The missile’s The flight trajectory is relativelyFlexible, 6 different flight trajectories can be pre-programmed through programming. According to reports, during the test firing of the Dannush missile, the range was 150 kilometers, but the error rate was only 10-25 meters.
Indian missile experts said that this type of missile is equipped with a sophisticated navigation system, which is accurate It is better than the Russian SS-21 missile and the American cruise missile. Prithvi series missiles canCarry various warheads including low-yield nuclear warheads. According to an Indian military official who asked not to be named, there are at least five types of Plitvi missile warheads. They include: standard high-energy/shrapnel integral warheads; submunition warheads, which can emit dual-purpose sub-bombs to deal with opponents' personnel and vehicles; equipped with inflammable sub-bombs, attacking targets such as army assembly areas; airport runway destruction Warheads can make the opponent's airport runway potholes and unusable; oil and gas bombs and cobalt ground warheads mainly attack trenches and important underground targets, such as underground command posts, underground airports and underground missile bunkers, and so on. These conventional warheads have been tested in full-scale models or in simulation. In addition, this type of missile can also be equipped with a dry-ton nuclear warhead, which can carry out attacks within a tactical range.
From a technical point of view, "Dannu" is undoubtedly a very crude product. First of all, the Pritvi missile itself has many design flaws: a tactical missile with a limited range uses a liquid rocket engine, which is very rare in today's tactical missiles. Due to the use of a liquid rocket engine, the Puri The preparation process for the launch of the Tvi missile is complicated and the preparation time is too long. The Plitvi missile body is more than 8 meters long, 1 meter in diameter, and weighs 4 tons, but the range is less than 3In contrast, the Hades tactical missile developed by France 20 years ago has a length of 7 meters, a diameter of 0.65 meters, a weight of 2 tons, and a range of 350 kilometers. The "Pershing" equipped by the United States more than 30 years ago The -1A tactical missile has a length of 10.5 meters, a projectile diameter of 1 meter, a weight of 4.6 tons, and a range of up to 740 kilometers.

Secondly, the Danush missile uses surface ships as the launch platform. , The lack of adequate concealment, coupled with the missile's too close range, forced surface ships to enter the enemy's shore-based firepower range before they could use the missile. Judging from the photos of the Danush missile launch test, the missile system occupies the entire helicopter hangar and take-off and landing platform after it is on the ship, which greatly affects the ship’s comprehensive combat capability. In all fairness, the Danush missile system looks more like a test product than actual combat equipment. However, the Indian Navy has put Danush missiles into mass production as actual combat equipment. According to reports, 6 of India’s existing 7 Sukanya-class patrol ships have been modified to deploy Danush missiles; in particular, India’s recently purchased Krivak-class guided missile frigate Trishul from RussiaModified Danush missile. The Trishul has a displacement of more than 4,000 tons and is the more advanced main battleship of the Indian Navy. After the improvement, it will be equipped with 8 Danush missiles. From the fact that India hastily installed the immature Danush missiles into ships, it is not difficult to see India's urgency to master its maritime strategic deterrent force.

From the perspective of developing maritime strategic deterrence, although the Danush missile has many problems, the Indian Navy can master the development and use experience of naval strategic missiles from this equipment It will help shorten the development process of advanced sea-based ballistic missiles in the future. The use of surface ships to equip ballistic missiles is obviously a stopgap measure. In the future, India will certainly develop submarine-launched long-range ballistic missiles to establish a triad of nuclear deterrent force.
