how do hydrographers/oceanographers detect hostile submarines?

Discussion in 'Joining Up - Royal Navy Recruiting' started by 2cool, Dec 4, 2012.

Welcome to the Navy Net aka Rum Ration

The UK's largest and busiest UNofficial RN website.

The heart of the site is the forum area, including:

  1. How do hydrographers/oceanographers detect hostile submarines?

    Rather specialist question I know but difficult for me to find this information on the web
  2. The big bang when the torpedo hits them.

  3. Not sure this would go down well at sift ahah
  4. Hydrographers/Oceanographers map the Ocean floor to make Charts find wrecks etc.

    TASOs or what ever they are called now have their boys,UCs or what ever they are called now, look for them using Sonar.

    It's a slight over egging of the HM trade. In order to use sonar to its full, you need to understand the environment in which it is operating. This includes water conditions and ocean bottom topography. The provision of such information is the job of the HM.

    While the principles of sonar and acoustic detection are the same for anti-submarine warfare, oceanography and sub-surface navigation, the frequencies that the various sensors/detection equipment use will vary, according to their role. Some are high frequency (and therefore low range) while others are low frequency (and thus high range).

    With regards to detecting hostile submarines, some sensors are able to provide certain acoustic information while others will give something else. By combining information from various sources - including fixed or towed air, surface and sub-surface detection systems - the Principal Warfare Officer and Anti-Submarine Warfare Director will detect, track, interrogate and potentially attack the target as necessary (and evade detection and attack themselves, should the target become hostile).

    Providing you understand the concept of what sonar is, how it works and what type of sensors are fitted to different classes of vessels, I imagine this will suffice for any Board or interview. You will not be expected to know the frequencies of them as this sort of information tends to be classified. As are most ASW tactics. Hence why it is difficult to find on the t'interwebs... :wink:

  7. It's harder to find the boat, let alone the information :)

    Reckon SF & SPB have just about summed-it for Sift purposes. If we relied exclusively on HM Officers for anything beyond data to help actually pinpoint a submarine (Or "target", as we prefer to call them), Topstop's on the money with this:

  9. They don't!!! They 'forecast' oceanographic conditions!!!

    Sonar operators using masses of sensors detect submarines.

    Like asking if a Meteorologist flies aircraft!!

  10. That brought back visions of ray path plotting!!!!! Not good!

  11. As an ex bender all the info above should suffice, if you need more military detail you will be given that as and when required in-service, security need to know basis.

    You can Google sonars generally and get a feeling for frequency verses range and definition

    Also note as a general rule Submarines do not transmit they just listen to all them noisy targets so as to comply with Topstops reasoning of the big bang theory, they are not known as the silent service for nothing.

    The linky will give you an understanding of the sonar equations

    How can you be an ex-bender sumo? I didn't know it was curable.

    If only they really were the silent service, eh? :frown:

  16. We had degrees of silence, on my last boat, a P boat, whenwe went quiet, shock mats were put down on the deck, all aux machinery that wasn’tneeded was switched off and all crew not on watch got in their bunks, on aBomber we just turned the movie down a notch.

  17. this has been a great thread for me to read ! Thanks for all your replies its all starting to make a lot more sense to me now
  18. In a nutshell 2cool.

    Helicopters go - 'Ping'

    Submarines go -

    Surface fleet rush around shouting and screaming and buggering up the sonar conditions!!!!
