What is a Sonar Dome?

A Sonar Dome (DOME,SONAR) is an inclosure, usually streamlined to reduce drag and turbulence, which is designed to provide protection for sonar transducer(s), sonar projector(s) or sonar hydrophone(s) while providing a minimum of interference with sound transmission and/or reception.

A Sonobuoy is a water buoyant item designed to intercept underwater sound waves for the specific purpose of retransmitting the received sounds in space via electromagnetic waves and/or intercept electromagnetic waves for the specific purpose of retransmitting the intelligence as underwater sound waves. See also BUOY, RADIO TRANSMITTING.

What is a Sonar Window?

A Sonar Window (WINDOW,SONAR) is an item which is part of a sonar dome or sonar transducer and which is so constructed as to afford little attenuation to sonar frequencies while aiding to cut down the water resistance of the part with which it is used.

What is a Sonar Acoustic Baffle?

A Sonar Acoustic Baffle (BAFFLE,ACOUSTIC,SONAR) is an item designed to be used with a sonar hydrophone or transducer to minimize sound pick-up from undesired directions.

What is a Sonar Dome Fairing?

A Sonar Dome Fairing (FAIRING,SONAR DOME) is an item designed to be mounted on a sonar dome and shaped so as to reduce the water resistance around the dome.

What is a Sonar Transmitter?

A Sonar Transmitter (TRANSMITTER,SONAR) is a single component designed to be used in conjunction with a projector or transducer for the specific purpose of generating underwater sound energy.

What is a Sonar Receiver-Transmitter?

A Sonar Receiver-Transmitter (RECEIVER-TRANSMITTER,SONAR) is a single component designed for the specific purpose of generating electromagnetic energy for the transmission of underwater sound waves and of intercepting and sometimes presenting intelligence from the received underwater sound waves.

What is a Sonar Data Computer?

A Sonar Data Computer (COMPUTER,SONAR DATA) is a computer which utilizes a power driven mechanism and/or electronic or electrical circuits to calculate two or more factors of sonar data, such as range, bearing, depth and/or sound velocity. Sonar is defined as the transmission and/or reception of underwater sound waves to determine the presence, location, nature of objects or noise on or in the water and/or for permitting an exchange of intelligence through water for communication purposes. Do not use for computers which derive single functions. See also COMPUTER, DEPTH CHARGE RELEASE TIME.

What is a Sonar Transponder?

A Sonar Transponder (TRANSPONDER,SONAR) is an item designed to be deployed from a ship for testing the accuracy of shipboard or airborne sonar systems. When depolyed in the water it hangs from a flotation device (buoy) which is equipped with a radar reflector. When interrogared by a pulse transmitted from a shipboard or airborne sonar, the transponder replies with an acoustic signal. Simultaneous range and azimuth measurements made by precision fire control radar aboard the interrogating platform provide accurate references for comparison with measurements taken from the interrogating sonar system.

What is a Sonar Data Signal Processor?

A Sonar Data Signal Processor (PROCESSOR,SIGNAL,SONAR DATA) is an item specifically designed to receive and process sonar target data supplied by a variety of shipboard and airborne sonar detection devices. Automatic processing of data received provides information for detecting, classifying and localizing surface and subsurface targets.

What is a Sonar Equipment Modification Kit?

A Sonar Equipment Modification Kit (MODIFICATION KIT,SONAR EQUIPMENT) is an item or items employed to modify sonar equipment.

What is a Sonar Towed Array Subassembly?

A Sonar Towed Array Subassembly (TOWED ARRAY SUBASSEMBLY,SONAR) is two or more different types of items, having a common mounting or mounted on each other, which together form a portion of a sonar towed array, but which in itself is not a complete functioning item and cannot be assigned a more definite item name.

NATO Supply Class 5845 is a classification within NATO Supply Group 58, which is dedicated to Communication, Detection, and Coherent Radiation Equipment.

Specifically, NATO Supply Class 5845 focuses on Underwater Sound Equipment. This class includes a wide range of equipment used for various underwater sound-related applications.

Underwater sound equipment is designed to transmit, receive, and process sound signals in underwater environments. This equipment is crucial for various purposes, including underwater communication, navigation, detection of underwater objects, and scientific research.

Some examples of equipment that fall under NATO Supply Class 5845 include underwater acoustic transducers, sonar systems, hydrophones, underwater communication systems, underwater acoustic recorders, and underwater sound analysis equipment.

These devices are used by military, scientific, and commercial organizations involved in underwater operations. They play a vital role in submarine warfare, underwater surveillance, marine research, offshore exploration, and underwater communication systems.

The classification of NATO Supply Class 5845 helps in standardizing the procurement and identification of underwater sound equipment among NATO member countries. It ensures interoperability and compatibility of equipment used by different nations during joint operations and exercises.

When referring to underwater sound equipment in documents or procurement processes, it is important to use the correct NATO Supply Class 5845 to ensure accurate identification and classification of the equipment being discussed or requested.

FSC 5845 Underwater Sound Equipment - United Kingdom (UK)

Includes Sonar Equipment; Underwater Listening Equipment; Sonobuoys; Sonobuoy Launchers; Fathometers; Sofar Equipment.

Note-Excludes oscillator items which should be classified in FSC 5955 or 5963; fiber optic items which should be classified in Group 60; electronic modules as defined under Class 5963; and electrical cable, cord and wire assemblies, harnesses and sets, related to FSG 58 equipment (see FSC 5995). In Group 58, more than in any other group, it frequently happens that the same name is listed as an index entry in each of several classes. In addition, that name may also appear as an entry in groups other than 58. Each such entry refers to a distinctly different part or assembly, even though the different items have the same name. The listing of the same names in two or more classes indicates that, in one form, the part or assembly covered by the name is applicable to the equipment covered by one class, and in another form is applicable to the equipment covered by another class. For example, the item name CODER, AUDIO FREQUENCY is applicable to two distinctly different assemblies, one of which has an application in cryptologic equipment, covered by Class 5810, and the other in radar equipment covered by Class 5840. Consequently the name CODER, AUDIO FREQUENCY is an entry under each of the two classes. When an item identification bears a name which is indexed under more than one class of Group 58, or in Group 58 and in some other group, the item will be classified in the same class as its next higher assembly in the manner described in the Federal Logistics Information System (FLIS) Procedures Manual, DoD 4100.39-M. Also excluded from this group are data transmission and communications equipment such as terminals, sensors and other devices designed for use with a configuration of ADPE.
