My question to ChatGPT about a non-existent CIWS:

What's the most effective positioning of the TurboLol CIWS on a light frigate?


The positioning of the TurboLol CIWS (Close-In Weapon System) on a light frigate should take into account several factors, such as the vessel's layout and mission requirements. However, there are some general principles that can guide the positioning of the CIWS.
Firstly, the TurboLol CIWS is an anti-aircraft and anti-missile system that is designed to provide close-range defense against incoming threats. Therefore, it should be positioned in a location that offers a clear field of fire in all directions, with minimal obstructions that could interfere with its operation.
Secondly, the CIWS should be positioned in a location that provides maximum coverage of the ship's vulnerable areas, such as the bridge, engine room, and weapons systems. This will help to ensure that any incoming threats can be detected and engaged as quickly as possible.
Thirdly, the placement of the TurboLol CIWS should take into account the weight distribution of the ship, as well as its stability and maneuverability. The CIWS should be positioned in a way that does not significantly affect the ship's balance or maneuverability, and that allows for easy access for maintenance and reloading.
Taking all these factors into account, a typical arrangement for a light frigate might be to mount the TurboLol CIWS on a raised platform at the aft end of the ship, providing a clear field of fire in all directions. Alternatively, the CIWS could be mounted on a pedestal on the ship's superstructure, providing a higher vantage point and better coverage of the ship's vulnerable areas. Ultimately, the positioning of the TurboLol CIWS will depend on the specific requirements of the ship and its mission, and should be determined through careful analysis and testing.

Stop treating these things as though they have intelligence. They have none, they are just a sophisticated autocomplete.

[Afif]

I don't have enough knowledge about functioning characteristics of SAS.

But i can confidently tell you is when it come to Submarine detection, It doesn't matter how high resolution imagin SAS can provide.
Medium frequency (bow mounted) sonars, and (specially) low frequency (VDS) sonars practically offer much longer detection range than high frequency sonar.


For example, iirc Thales new gen CAPTAS low frequency VDS has frequency range of 0.9-2.1kHz. (CAPTAS-4 has a detection range up to 150km)
Or Atlas Elektronik developed 'Active Towed Array Sonar' (ACTAS) has a frequency range of 1.4-2.4 kHz. (And has a detection range up to 60km. Similar to CAPTAS-2)

On the other hand AFAIK SAS usually has frequency range of 30-100kHz or higher.

Read the brochure below, you have an idea how SAS operates.

https://www.kongsberg.com/globalassets/maritime/km-products/product-documents/high-resolution-interferometric-synthetic-aperture-sonar---hisas-1030/

Although SAS can be used to detect mines at close ranges.
But I am not sure if navies actually uses it.


And no matter what, Variable Depth Sonar (VDS) will always be indispensable part of ASW missions.

Because, sound waves bounce up and down and bend through different layers of temperature and salinity in the water. A submarine can “hide” under a layer of cold water where an active hull-mounted sonar (HMS) can’t reach since the sound wave will bounce off the layer up against the surface. For this reason, surface ships have variable depth sonars (VDS) that they can dip below the layers and search.

 

[UkroTurk]

Yes, synthetic aperture sonar (SAS) technology can provide advantages in detecting submarines that are hiding beneath layers of cold water. Here's how synthetic aperture sonar can offer benefits similar to variable depth sonars (VDS):

1. Improved Resolution: SAS systems use advanced signal processing techniques and longer integration times to achieve high-resolution imaging. This enhanced resolution allows for better detection and classification of submerged targets, including submarines hiding under cold water layers.

2. Increased Range: SAS systems can operate at longer ranges compared to traditional sonar systems. This extended range enables the detection of submarines hiding at greater distances, even under challenging environmental conditions.

3. Enhanced Imaging Capabilities: SAS produces detailed images of the underwater environment, allowing operators to analyze the data and identify submarines that may be concealed beneath cold water layers. The synthetic aperture processing techniques help compensate for the effects of scattering and attenuation in the water column.

4. Wide Swath Coverage: SAS systems can provide wide swath coverage, meaning they can survey a larger area in a single pass. This capability allows for efficient and comprehensive search operations, increasing the chances of detecting submarines hiding beneath cold water layers.

5. Flexibility and Adaptability: SAS systems can be integrated into various platforms, including surface ships, unmanned underwater vehicles (UUVs), and towed arrays. This flexibility enables deployment in different operational scenarios and enhances the overall capabilities of the naval forces.

While synthetic aperture sonar technology offers advantages in detecting submarines hiding beneath cold water layers, it is important to note that both SAS and VDS technologies have their own strengths and limitations. The selection of the appropriate system depends on specific operational requirements, environmental conditions, and platform capabilities.




Regarding the specific scenario of detecting submarines hiding beneath cold water layers, both synthetic aperture sonar (SAS) and variable depth sonar (VDS) technologies have their respective strengths and limitations:

2. Simplicity and Reliability: VDS systems are generally simpler in design and operation compared to SAS, making them reliable and easier to maintain.

3. Real-Time Operation: VDS can provide real-time sonar data, allowing for immediate detection and response to potential threats.

Limitations of VDS Technology:

1. Limited Range: VDS systems typically have shorter detection ranges compared to SAS, which can limit their effectiveness in detecting submarines that are farther away.

2. Narrow Coverage Area: VDS systems have a narrower coverage area compared to SAS, requiring more time and effort to survey a larger area.

3. Vulnerability to Countermeasures: VDS systems can be susceptible to countermeasures employed by submarines, such as deploying decoys or noise-generating devices to confuse or evade detection.

It's important to note that the effectiveness of both SAS and VDS technologies in detecting submarines hiding beneath cold water layers can be influenced by various factors, including the specific operational conditions, environmental factors, and the capabilities of the platforms on which they are deployed.
