According to media reports, the electronic reconnaissance ship "Rivanz", built by the mainland for the Pakistan Navy, was recently delivered. The ship was built by the Fujian Mawei Shipyard with a maximum displacement of 5188 tons. With the delivery of the ship, the Pakistan Navy has become the sixth navy in the world to have a specialized electronic reconnaissance ship after the Indian Navy.
Electronic reconnaissance ships originated in the United States, and are equipped with a large number of radio receivers, radar receivers, terminal demodulation, and receiving equipment, which are mainly used to collect electronic signals, radar bands, and communication frequency bands of enemy ships, or to interfere with the enemy's electromagnetic signals.
Electronic reconnaissance ships have high requirements for the research and development capabilities of electronic equipment and the ability to build ships, and there are only a handful of countries in the world that can build electronic reconnaissance ships. The United States was the first country to develop electronic reconnaissance ships, with a maximum of 20 electronic reconnaissance ships. The "Laurenzen", which has the largest displacement, exceeded 10,000 tons.
Since then, the Soviet Navy has also developed its own electronic reconnaissance ships to monitor U.S. missile launches. Decades later, China and France also built their own electronic reconnaissance vessels, and in 2021, India joined the ranks as the fifth country in the world to have such a shipbuilding capability.
【Polaris】
India's electronic reconnaissance ship project, codenamed VC-11184, was launched in 2014 as part of India's missile defense program, which in turn is supported by the "Make in India" program. The two programs complemented each other, which led to a significant acceleration in the construction of the electronic reconnaissance ship, called the Polaris, which was completed in just six years and commissioned in April 2021.
The total cost of the Polaris is Rs 1,500 crore, or about $220 million. Equipped with an X-band radar and two S-band radars, it integrates command, control, and communication systems, and is capable of monitoring electromagnetic signals generated by aircraft, ships, and missiles of other countries, and collecting electronic intelligence.
The radars on the "Polarstar" are all active phased array radars, which have the characteristics of wide monitoring range, high scanning accuracy, and strong anti-jamming ability, and a spokesman for the Indian Navy said that since India's two major neighbors have ballistic missiles, the Indian Navy, equipped with electronic reconnaissance ships, will have nothing to hide from these missiles.
Generally speaking, what India has, Pakistan will soon have. Sure enough, after two years of service on the "Polarstar", Pakistan had its own electronic reconnaissance ship. Electronic reconnaissance ships are the most mysterious type of ships, which can be called early warning aircraft at sea, and their prices are so expensive that ordinary countries simply cannot afford them.
所以，印度媒体在报道这则消息的时候说，china gifts Pakistan its 1st spy ship。 Gifts这个词耐人寻味，是不是赠送的现在不得而知，但至少抵消了印度海军的优势。
Everyone knows what level of radar technology in India is. In 2021, they showed off an active phased array radar called the L-273 for the Tejas fighter with rough workmanship, bulky size, and far inferior performance to the KLJ-7A radar on the Thunder fighter in all aspects.
In addition, the radar of the early warning aircraft developed by India adopts a very alternative four-sided array layout, the reason is that its radar technology is not good, and it cannot solve the problem of omnidirectional coverage of the three-sided array, especially when the left and right are close to the 60-degree limit angle, the beam gain is not enough, the signal-to-noise ratio is low, and the power and accuracy are greatly affected.
It is not difficult to understand why their "Polaris" is more than 10,000 tons, because they can't solve the problem of radar miniaturization, so they can only increase the hull.
Now that the Pakistan Navy has the "Riwanzi", India can calm down and re-examine whether there is a matching strength behind its crazy ambitions.
