Marichka
Marichka ( uk, Марічка) is a Ukrainian-made multi-purpose autonomous underwater vehicle (AUV) capable of performing underwater attack missions, as well as cargo transportation and reconnaissance. Development The first successful test of the AUV was announced on August 24, 2023. On August 29, a video of the Marichka's tests was revealed to the public. Marichka is designed to be capable of hitting landing ships, boats, submarines and missile corvettes, as well as coastal fortifications and bridge supports. Outside of strike applications, the AUV can also transport military and civilian cargo, and perform reconnaissance missions. Specifications While dormant, the AUV can be activated by timer or via signal. The manufacturer claims that Marichka can be concealed from hydroacoustic search scanners and can withstand electronic warfare countermeasures. Marichka is designed to hit areas of warships beneath the waterline, to maximise efficacy. See also *MAGURA V5 - USV developed f ...

Sea Baby
Sea Baby is a Ukraine, Ukrainian multi-purpose unmanned surface vehicle (USV) developed for use by the Security Service of Ukraine (SBU) during the Russian invasion of Ukraine. It is able to carry an explosive payload for use in kamikaze attacks, or equipped with other equipment loadouts for more specialised use. Development SBU brigadier general :uk:Лукашевич Іван Володимирович, Lukashevych Ivan Volodymyrovych proposed the idea of the agency operating unmanned attack boats, and early USV models were designed in July 2022 in collaboration with specialists from the Ukrainian Navy and assorted private companies. Later, the SBU decided to develop drones independently, culminating in the Sea Baby design for operational use by the SBU, while what eventually became the MAGURA V5 became operated by the Main Directorate of Intelligence (Ukraine), Main Directorate of Intelligence (GUR). While the GUR's smaller and more manoeuvrable MAGURA V5 is used designed primari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autonomous Underwater Vehicle
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs. History The first AUV was developed at the Applied Physics Laboratory at the University of Washington as early as 1957 by Stan Murphy, Bob Francois and later on, Terry Ewart. The "Special Purpose Underwater Research Vehicle", or SPURV, was used to study diffusion, acoustic transmission, and submarine wakes. Other early AUVs were developed at the Massachusetts Institute of Technology in the 1970s. One of these is on dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kyiv is the nation's capital and largest city. Ukraine's state language is Ukrainian; Russian is also widely spoken, especially in the east and south. During the Middle Ages, Ukraine was the site of early Slavic expansion and the area later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. The state eventually disintegrated into rival regional powers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ukrainian Hryvnia
The or ( ; uk, гривня , : ''hrn''; sign: ₴; code: UAH) has been the national currency of Ukraine since 2 September 1996. The hryvnia is divided into 100 . It is named after a measure of weight used in medieval Kievan Rus'. Name Etymology The currency of Kievan Rus' in the eleventh century was called ''grivna''. The word is thought to derive from the Slavic ''griva''; c.f. Ukrainian, Russian, Bulgarian, and Serbo-Croatian / ''griva'', meaning "mane". It might have indicated something valuable worn around the neck, usually made of silver or gold; c.f. Bulgarian and Serbian ''grivna'' (, "bracelet"). Later, the word was used to describe silver or gold ingots of a certain weight; c.f. Ukrainian ''hryvenyk'' (). Plural The nominative plural of hryvnia is ''hryvni'' ( uk, гривні), while the genitive plural is ''hryven’'' ( uk, гривень). In Ukrainian, the nominative plural form is used for numbers ending with 2, 3, or 4, as in ''dvi hryvni'' (дві г ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Underwater Acoustics
Underwater acoustics is the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries. The water may be in the ocean, a lake, a river or a tank. Typical frequencies associated with underwater acoustics are between 10 Hz and 1 MHz. The propagation of sound in the ocean at frequencies lower than 10 Hz is usually not possible without penetrating deep into the seabed, whereas frequencies above 1 MHz are rarely used because they are absorbed very quickly. Underwater acoustics is sometimes known as hydroacoustics. The field of underwater acoustics is closely related to a number of other fields of acoustic study, including sonar, transduction, signal processing, acoustical oceanography, bioacoustics, and physical acoustics. History Underwater sound has probably been used by marine animals for millions of years. The science of underwater acoustics began in 1490, when L ...

Electronic Warfare
Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults. The purpose of electronic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. EW can be applied from air, sea, land, and/or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets. The electromagnetic environment Military operations are executed in an information environment increasingly complicated by the electromagnetic spectrum. The electromagnetic spectrum portion of the information environment is referred to as the electromagnetic environment (EME). The recognized need for military forces to have unimpeded access to and use of the electromagnetic environment creates vulnerabilities and opportunities for electronic warfare in support of military operations. Within the informa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Security Service Of Ukraine
The Security Service of Ukraine ( uk, Служба безпеки України, translit=Sluzhba bezpeky Ukrainy}) or SBU ( uk, СБУ, link=no) is the law enforcement authority and main intelligence and security agency of the Ukrainian government, in the areas of counter-intelligence activity and combating terrorism. The Constitution of Ukraine defines the SBU as a military formation, and its staff are considered military personnel with ranks. It is subordinated directly under the authority of the president of Ukraine. The SBU also operates its own special forces unit, the Alpha Group. The SBU is the successor of the Ukrainian branch of the Soviet KGB, created after the Declaration of Independence of Ukraine in 1991. The agency was negatively seen by the Ukrainian public, as they were widely regarded as corrupt and were for conducting arrests and intimidations of political dissidents. After the Revolution of Dignity, the SBU went through a restructuring with the tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomous Underwater Vehicles
In developmental psychology and moral, political, and bioethical philosophy, autonomy, from , ''autonomos'', from αὐτο- ''auto-'' "self" and νόμος ''nomos'', "law", hence when combined understood to mean "one who gives oneself one's own law" is the capacity to make an informed, uncoerced decision. Autonomous organizations or institutions are independent or self-governing. Autonomy can also be defined from a human resources perspective, where it denotes a (relatively high) level of discretion granted to an employee in his or her work. In such cases, autonomy is known to generally increase job satisfaction. Self-actualized individuals are thought to operate autonomously of external expectations. In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine. Sociology In the sociology of knowledge, a controversy over the boundaries of autonomy inhibited analysis of any concept beyond relative aut ...
