Editor’s Note

“to save themselves, in order to destroy the enemy” is a war the only way. Own humanity since the war, attack the weapon with the strong defense shield, just as both sides of the coin, closely linked, the shift. Currently, the world is stepping up the development of maritime power, while the sophisticated weapons and equipment, pay more attention to the impact of naval platforms, with a view to the future of naval warfare, weapons of all types to ensure the best out of combat effectiveness. Ships impact the ocean shower of blood in the 20th century, born out of the technology, renewed vitality. Recently, I interviewed a director of Institute of naval equipment, Yu Wang, ask him to ship impact on the technology, history, research status and trends, as well as naval and navy of the future construction of far-reaching implications are described, are excerpts from published to readers.

impact technology: born out of the smoke of war

Q: According to foreign reports, in 2005, the U.S. Navy on the “American” aircraft had lasted 25 days of ship underwater explosion shock tests; 2008, the U.S. Navy and on the “Mesa Verde” amphibious transport ship to the underwater explosion shock tests. As we all know, ship impact studies, often using real ships, costly, but the United States so Costly Why real ship explosion test it? Why is the ship’s anti-blast performance by such attention?

Yu Wang: blast resistant naval research grew out of the smoke flames. In September 1942, the Japanese submarine B 19 Iraqi combat patrol in the Solomon Sea, the U.S. military experience “Hornet” aircraft carrier battle groups, the Japanese Navy attacked the U.S., resulting in “Hornet” aircraft carrier battle group 1 and 1 destroyers sank a battleship injured heavy losses.

1982 年 5 4, Battle of the Falklands, Argentina “super flag” fighter with the French “Exocet” missile sank the British “Sheffield” the destroyer, the first air-ship missiles sank the large warships of the wars. In April 1988, the U.S. was the most advanced missile frigate “Roberts” in the implementation of the escort mission to the Gulf region is one way the old Soviet-made M08 mines exploded hit 8-meter break and cause the fire, almost sank.

a series of painful lessons of naval warfare, making the country fully aware of the Navy ships such as the impact there is weak, just as Ni Wan into the sea, a precarious state. In fact, the U.S. Navy back in 1860 for a test blast-resistant hull. World War II, the U.S. Navy was willing to spend heavily in technical research ship impact, to improve the viability of warships at sea and continued combat capability. Not long ago, newly developed cost U.S. $ 61 million “Sea Wolf” class nuclear submarine for the real assessment test boat underwater explosion, the explosion of the dose up to 1 million pounds (4536 kilograms), is the ability to fully assess impact submarines.

cast strong shield at sea: Navy’s dream of world

Q: attack and anti-strike capability are two aspects of naval combat, as the ancient warrior spear and shield, as only paid attention to and ignore the sharp spear of a solid shield, the same will be hors de combat. Please tell us about the impact technology research vessel status.

Yu Wang: To understand the impact technology ships, we must first understand the impact and meaning of underwater explosions. Impact refers to a system in a relatively short period of time (usually in milliseconds) by transient excitation, its location, speed or sudden changes in acceleration of physical phenomena. In modern naval warfare, the enemy ships to attack the main impact being the source of three: contact explosion, water, non-contact explosion, firing their weapons, the impact of recoil. Underwater vessels which suffered an explosion than the probability of non-contact probability of a direct hit big.

because the density of water is about 800 times the air, while the compressibility of air 1/20000-30000 only is a good energy transfer explosives were, the impact will occur leading to hull buckling, damage or even break , the equipment inside the ship will be the impact of large-scale destruction of failure, crew casualties will occur due to the impact, resulting in people, and ship-doom.

Currently, the world’s research vessel the highest level of impact was undoubtedly the United States, followed by NATO, Australia, Japan and other countries, and even some military strength is not strong countries such as South Korea are concerned about ships of the impact study. Statistics show that only from the Vietnam War to the mid-1980s, the U.S. Navy ships at least all kinds of underwater explosion shock testing of ship more than 30 times and has always insisted on the first ship to actually ship the system acceptance test of underwater explosions, and will this required to write code. Explosion test, all operators are in position on the war, so both ships as the ability of the system’s impact assessment tools, but also as a simulated combat exercises, until acceptance through to delivery units.

impact of foreign naval vessels have in a significant common ground – have established a relatively complete and effective assessment of the overall combat simulation system, a sound organization and management of both institutions , have a comprehensive system of standards, as well as a comprehensive assessment of the impact of means testing, means a wealth of shock protection, an advanced method of simulation software and models, and the mandatory first ship of ship underwater explosion shock test assessment policy.

resilience: dark blue shield

Q: modern high-tech weapons on ships and shipboard equipment to the growing threat. Military needs and the reality gap between urgent need and to improve the impact of China’s naval capabilities, please tell us about the ships and their impact on the development prospects of the impact of China’s naval armaments.

Yu Wang: Looking at the world naval power of strategic planning and development process, not difficult to find in the modern regional conflicts and local wars at sea, the maritime powers on the one hand the pursuit of long-range high-tech weapons, information , network-based precision strike capability, but also pay more attention to maritime operations as a platform – the viability of the ship’s self-protection, to protect the sea in all kinds of sea-based weapons effectively combat effectiveness. Battle of the Falklands in the UK “Sheffield” frigate hit by an Exocet missile will lead to the sinking, the United States 320 tons of “Seaman Rafael” number, the Battle of Okinawa in World War II by the Japanese four bombs and five loaded full of explosives, “Kamikaze” aircraft hit the injury, but the successful return naval port. In the 1980s, the Persian Gulf conflict, the United States four different types of ships were hit by mines and torpedoes, are not sunk. These tells us: After the ship underwater impact assessment test in the harsh combat environment can be fully and effectively save the fighting.

improve ship survivability in the 21st century, one of the main objectives pursued ships. Modern war is a high-tech war ships equipped with a large number of complex operational systems, electronic systems, navigation systems, the use of more stringent environmental requirements; advanced underwater weapons of mass destruction attack ships also increase the impact of even worse conditions As an important part of naval combat level of impact resistance, will affect the entire battlefield situation, all of which make the enhanced impact resistance vessels to become a more urgent and arduous task.

Relatively speaking, China’s naval anti-submarine research in blast late start of ship underwater explosion tests carried out less, the lack of experimental data is bound to impact research and restricting our ships design development. China’s limited investment in national defense and limited the size of ships, forcing us to have every possible manipulation in the next war ships can “reliably serve the purpose.” In order to effectively improve the fighting capacity of our ships, to enhance ship shock test is an important part. Navy only has a tough defense of anti-ship weapons to attack the ability to assume good a responsible big country to defend territorial waters, justice, the glorious mission of safeguarding peace.
