USNS Invincible (T-AGM-24)
USNS ''Invincible'' (T-AGM-24), also known as ex-''AGOS 10'', is one of two tracking ships operated by the Military Sealift Command. One of the radars it carries is the Cobra Gemini dual band, X band and S band, radar. Like other members of the ''Stalwart'' class of ocean surveillance ships, the original mission of the ''Invincible'' was to patrol the oceans looking for submarines with her Surveillance Towed Array Sensor System (SURTASS), a large passive sonar array. The ship was reclassified from AGOS-10 to AGM-24 on April 4, 2000 after she was refitted as a missile range instrumentation ship. ''Invincible'' provides a platform for the Cobra Gemini dual-band radar developed by the United States Air Force to support data collection requirements on theater ballistic missiles. The Military Sealift Command retains custody for United States Air Force use for deploying a mobile surveillance and tracking radar system.

Surveillance Towed Array Sensor System
The AN/UQQ-2 Surveillance Towed Array Sensor System (SURTASS), colloquially referred to as the ship's "Tail", is a towed array sonar system of the United States Navy. SURTASS Twin-Line consists of either the long passive SURTASS array or the Twin-line array consisting of two shorter passive arrays towed side by side. The Twin-line Engineering Development Model was installed on USNS ''Assertive'', and the first production model was installed on USNS ''Bold''. Both ships are no longer serving as SURTASS units. , SURTASS was deployed on the four ''Victorious''-class vessels and the (a small-waterplane-area twin hull (SWATH) vessel). History SURTASS began as development program in 1973 using the new research vessel ''Moana Wave''. In 1980 SURTASS passed OPEVAL. The new ''Stalwart''-class ocean surveillance ships had the first contract awarded on 26 September 1980 and were similar to the prototype ship, the ''Moana Wave''. Initially the SURTASS system were passive, receive only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ships Built By Tacoma Boatbuilding Company
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

Cold War Auxiliary Ships Of The United States
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strait Of Hormuz
The Strait of Hormuz ( fa, تنگه هرمز ''Tangeh-ye Hormoz'' ar, مَضيق هُرمُز ''Maḍīq Hurmuz'') is a strait between the Persian Gulf and the Gulf of Oman. It provides the only sea passage from the Persian Gulf to the open ocean and is one of the world's most strategically important choke points. On the north coast lies Iran, and on the south coast lies the Musandam peninsula, shared by the United Arab Emirates and Musandam Governorate, an exclave of Oman. The strait is about long, with a width varying from about to . A third of the world's liquefied natural gas and almost 25% of total global oil consumption passes through the strait, making it a highly important strategic location for international trade. Etymology The opening to the Persian Gulf was described, but not given a name, in the ''Periplus of the Erythraean Sea'', a 1st-century mariner's guide: In the 10th17th centuries AD, the Kingdom of Ormus, which seems to have given the stra ...

Theater Ballistic Missile
A theatre ballistic missile (TBM) is any ballistic missile with a range less than , used against targets " in-theatre". Its range is thus between that of tactical and intermediate-range ballistic missiles. The term is a relatively new one, encompassing the former categories of short-range ballistic missile and medium-range ballistic missile. Examples of this type of in-theatre missile are the Soviet RT-15, TR-1 Temp and American PGM-19 Jupiter missile, both from the 1960s. Specific TBMs Specific types of TBMs (current, past and under development) include: * B-611 * BP-12/A * DF-11 * DF-12/M20 * DF-15 * Type 621 * Type 631 * DF-2 * DF-16 * DF-17 * DF-21 ( China) , (Saudi Arabia) * Hadès * Pluton * SE.4200 * SSBS S1 * Agni I * K-15 * Prahaar * Pragati (planned) * Pralay * Pranash (planned) * Prithvi I * Prithvi II * Prithvi III * Shaurya * Agni II * Agni-P * Fateh-110 * Fateh-313 * Fateh Mobin * Naze'at * Qiam 1 * R ...

Data Collection
Data collection or data gathering is the process of gathering and measuring information on targeted variables in an established system, which then enables one to answer relevant questions and evaluate outcomes. Data collection is a research component in all study fields, including physical and social sciences, humanities, and business. While methods vary by discipline, the emphasis on ensuring accurate and honest collection remains the same. The goal for all data collection is to capture quality evidence that allows analysis to lead to the formulation of convincing and credible answers to the questions that have been posed. Data collection and validation consists of four steps when it involves taking a census and seven steps when it involves sampling. Regardless of the field of or preference for defining data (quantitative or qualitative), accurate data collection is essential to maintain research integrity.
