Tir II (IPS 18)
The Tir II (IPS 18) is an Iranian built small fast attack craft torpedo boat featuring a low, flush hull to reduce its radar cross-section. The radar is set on a retractable mast, with fixed 21" tubes inside the superstructure. Engines exhaust at the waterline to reduce its IR signature. Built by Iranian Maritime Industries (a subsidiary of the state-owned DIO company), the '' Bavar-class'' missile-armed boats are being acquired to replace the ''Tir-II''s. Ten units are in service, believed to be manned by the IRGCN, not the regular Iranian navy. In late 2006/early 2007 six of the sixteen vessels built were transferred to the Syrian Navy The Syrian Navy, officially the Syrian Arab Navy ( ar, الْبَحْرِيَّةُ الْعَرَبِيَّةُ السُّورِيَّةُ, al-Baḥrīyah al-ʿArabīyah as-Sūrīyah), is the navy branch of the Syrian Armed Forces.

Torpedo Boat
A torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy's. A swarm of expendable torpedo boats attacking en masse could overwhelm a larger ship's ability to fight them off using its large but cumbersome guns. A fleet of torpedo boats could pose a similar threat to an adversary's capital ships, albeit only in the coastal areas to which their small size and limited fuel load restricted them. The introduction of fast torpedo boats in the late 19th century was a serious concern to the era's naval strategists, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast Attack Craft
A fast attack craft (FAC) is a small, fast, agile, offensive, often affordable warship armed with anti-ship missiles, gun or torpedoes. FACs are usually operated in close proximity to land as they lack both the seakeeping and all-round defensive capabilities to survive in blue water. The size of the vessel also limits the fuel, stores and water supplies. In size they are usually between 50–800 tonnes and can reach speeds of . A fast attack craft's main advantage over other warship types is its affordability. Many FACs can be deployed at a relatively low cost, allowing a navy which is at a disadvantage to effectively defend itself against a larger adversary. A small boat, when equipped with the same weapons as its larger counterpart, can pose a serious threat to even the largest of capital ships. Their major disadvantages are poor seagoing qualities, cramped quarters and poor defence against aerial threats. History 19th century As early as the mid-19th century, the Jeune ...

Radar Cross-section
Radar cross-section (RCS), also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: *the material with which the target is made; *the size of the target relative to the wavelength of the illuminating radar signal; *the absolute size of the target; *the incident angle (angle at which the radar beam hits a particular portion of the target, which depends upon the shape of the target and its orientation to the radar source); *the reflected angle (angle at which the reflected beam leaves the part of the target hit; it depends upon incident angle); *the polarization of the transmitted and the received radiation with respect to the orientation of the target. While important in detecting targets, strength of emitter and distance are not factors that affect the calculation of an RCS becaus ...

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Syrian Navy
The Syrian Navy, officially the Syrian Arab Navy ( ar, الْبَحْرِيَّةُ الْعَرَبِيَّةُ السُّورِيَّةُ, al-Baḥrīyah al-ʿArabīyah as-Sūrīyah), is the navy branch of the Syrian Armed Forces. The main role of the Syrian Navy is to defend the country's coasts and ensure the security of the territorial waters of Syria. The Coastal Defense Forces and the Syrian Marines have been attached to the Navy since the late 20th century. The Syrian navy is a relatively small navy with only 4,000 sailors, in addition to 2,500 reservists and 1,500 marines. It is under the Syrian Army's Latakia regional command with its fleet based in the ports of Baniyas, Latakia, Minet el-Beida, and Tartus. It is the smallest part of the Syrian Armed Forces. History On 29 August 1950, the Syrian Navy was established following the procurement of a few naval vessels from France. The initial personnel consisted of army soldiers who had been sent to French naval academies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Ships Of Syria
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...
