Советтік "Термит" кемеге қарсы зымыран және оның түрлері

The P 15 Termit (П 15 "Термит"; ) is an anti ship missile developed by the Soviet Union's Raduga design bureau in the 1950s. Its GRAU designation was 4K40, its NATO reporting name was Styx or SS N 2. China acquired the design in 1958 and created at least four versions: the CSS N 1 Scrubbrush and CSS N 2 versions were developed for ship launched operation, while the CSS C 2 Silkworm and CSS C 3 Seersucker were used for coastal defence. Other names for this basic type of missile include: HY 1, SY 1, and FL 1 Flying Dragon (Chinese designations typically differ for export and domestic use, even for otherwise identical equipment), North Korean local produced KN 1 or KN 01, derived from both Silkworm variants and Russian & USSR P 15, Rubezh, P 20 P 22
Despite its large size, thousands of P 15s were built and installed on many classes of ships from torpedo boats to destroyers, and coastal batteries and bomber aircraft (Chinese versions).

The P 15 was not the first anti ship missile in Soviet service; that distinction goes to the SS N 1 Scrubber, and to the aircraft launched AS 1 Kennel. The SS N 1 was a powerful but rather raw system, and it was soon superseded by the SS N 3 Shaddock. This weapon was fitted to 4,000 ton Kynda class cruisers and replaced an initial plan for 30,000 ton battlecruisers armed with and guns. Rather than rely on a few heavy and costly ships, a new weapons system was designed to fit smaller, more numerous vessels, while maintaining sufficient striking power. The P 15 was developed by the Soviet designer Beresyniak, who helped in the development of the BI rocket interceptor.

The first variant was the P 15, with fixed wings. The basic design of the missile, retained for all subsequent versions, featured a cylindrical body, a rounded nose, two delta wings in the center and three control surfaces in the tail. It was also fitted with a solid fueled booster under the belly. This design was based on the Yak 1000 experimental fighter built in 1951. The weapon was meant to be cheap, yet still give an ordinary missile boat the same 'punch' as a battleship salvo. The onboard electronics were based on a simple analog design, with a homing conical scanning radar sensor. It used a more reliable rocket engine with acid fuel in preference to a turbojet. Some shortcomings were never totally solved, due to the liquid propellant of the rocket engine: the acid fuel gradually corroded the missile fuselage. Launches were not possible outside a temperature range of After this engagement, interest in this type of weapon was raised in both offensive weapons and defensive weapons such as close in weapon systems (CIWS) and electronic countermeasures (ECM).

During the Indo Pakistani War of 1971, Indian Osa class boats raided the port of Karachi in two highly successful operations causing severe damage and sinking several ships with their P 15s, among them the destroyer, Khaibar. She was a former Battle class destroyer, originally designed as an anti aircraft ship. Her armament might be effective against conventional air threats, (mounting 5 × 114 mm guns and several 40 mm Bofors), but had little chance against anti ship missiles. These raids were meant to strike Karachi and destroy the Pakistani Navy in Western Pakistan. The first action, Operation Trident, was carried out by three Osa class missile boats on the night of 5 December. 'Operation Trident' involved:
INS Nipat (Lt. Cdr B. N Kavina, Vir Chakra (VrC))
INS Nirghat (Lt. Cdr I. J Sharma, Ati Vishisht Seva Medal (AVSM), VrC)
INS Veer (Lt. Cdr O. P Mehta, VrC, NM)

Around 20:30, a target was acquired by radar, at a distance of over 40 mile (64 km), and Nirghat fired two missiles. This target was the destroyer Khaibar, sailing at The crew of the ship saw a "bright light" in the sky, low on the water. Believing it to be the afterburner of a fighter aircraft, Khaibar opened fire with her Bofors guns, but these were not effective against such a small, fast target. The missile struck the starboard side at 22:45, destroying the electrical system. One of the boilers, possibly struck by the HEAT charge, also exploded. Despite thick smoke and a fire, Khaibar was still able to engage the second missile, again mistaking it for an enemy fighter. This missile struck the ship four minutes after the first, destroying and quickly sinking her. During this action, Nipat attacked another two ships; the cargo vessel Venus Challenger, which was carrying ammunition from Saigon, was destroyed. Her escort, the destroyer PNS Shahjahan was severely damaged and later scrapped. Veer then attacked Muhafiz at 23:05, (she was a minesweeper that had witnessed the attacks against Khaibar); she was hit and disintegrated, throwing most of the crew into the water before she sank. Nipat fired two missiles at the port of Karachi. This is the first known use of an anti ship missile against land targets. Large oil tanks, identified by radar, were hit by the first missile, destroying it, while the second weapon failed. Over the following nights there were other ship actions. Karachi was again attacked with missiles, while Petya class frigates provided anti submarine protection to the Osa class boats. On the night of 8 December, in the second operation, Operation Python, the Osa class boat Vinash, escorted by two frigates, fired missiles at Karachi in a six minute action. One missile hit an oil tank, destroying it. The British ship Harmattan was sunk, the Panamanian ship Gulfstar was set on fire. The Pakistan Navy fleet tanker, PNS Dacca, was badly damaged and only survived because the commanding officer, Captain. S. Q. Raza S. J. P. N., ordered the release of steam in the pipes that prevented the fire reaching the tanks. Though anti aircraft guns opened fire in response, they only managed to hit a Greek ship, Zoë, that was moored in the port and consequently sank. In all these actions against large ships, the P 15 proved to be an effective weapon, with a devastating warhead. Out of eleven missiles fired, only one malfunctioned, giving a 91% success rate. This gave every Osa FAC the possibility of striking several targets. Big ships, without any specialized defence, were targets for P 15s.

CIA inspected and analyzed data on Styx missiles from the guidance systems of missiles delivered to Indonesia. The US Navy had underestimated the threat of Soviet missiles, but after 1967 this changed. The US Navy thought that North Vietnam missile boats and coastal defenses using P 15 missiles could be met by US vessels off the coast and that ECM and air defense missiles would be effective countermeasures. The Soviet Union in fact decided not to supply P 15 missiles to North Vietnam, even though a promise to do so had been made in 1965. In April 1972 the US Navy claimed to have been attacked by P 15 missiles and they were shot down by Terrier missiles.

Despite these early successes, the 1973 Yom Kippur War saw P 15 missiles used by the Egyptian and Syrian navies prove ineffective against Israeli ships. The Israeli Navy had phased out their old ships, building a fleet of Sa'ar class FACs: faster, smaller, more maneuverable and equipped with new missiles and countermeasures. Although the range of the P 15 was twice that of the Israeli Gabriel, allowing Arab ships to fire first, radar jamming and chaff degraded their accuracy. In the Battle of Latakia and Battle of Baltim, several dozen P 15s were fired and all missed. Arab ships did not possess heavy firepower required for surface combat against enemy vessels, usually only 25 and 30 mm guns, and Osa and Komar boats were not always able to outrun their Israeli pursuers.

P 15 variants, including the Chinese duplication "Silkworm", were employed by Iran against Iraq in the 1980–1988 Iran–Iraq War, with some success. As the Iranian coastline is longer than Iraq's, control of the Persian Gulf was relatively easy. Shore batteries with missiles can control a large part of this area, especially around the Hormuz Strait. Iraq also acquired Silkworms, some with an IR homing ability. Iraqi OSA class missile boats equipped with SS N 2 used them against the IRIN navy, managed to hit and sink an Iranian Kaman class fast attack craft, but sustained heavy losses, especially from Iranian Harpoons and Mavericks. Iraqi forces combined SS N 2 (P 15 Termit) launched from Tu 22, Exocet missiles launched from Mirage F1 and Super Etendard, as well as Silkworm missiles and C 601 missiles launched from Tu 16 and H 6 bombers, bought from the Soviet Union and China to engage the Iranian Navy and tankers carrying Iranian oil.

During the First Gulf War an Iraqi missile crew attacked US battleship Missouri with a Silkworm, while it was escorting a fleet of minesweepers engaged in coastal anti mine operations. HMS Gloucester engaged the missile with a salvo shot of Sea Dart missiles which destroyed it after it had flown over its initial target.

The P 15 missile family and their clones were widely deployed from the 1960s. The German Navy, after reunification, gave its stock of almost 200 P 15s to the United States Navy in 1991, these weapons being mainly the P 15M/P 22. They were used for missile defence tests.
