a number of nations already do have a degree of subsea mapping in place. however, as strange as it may seem, the subsea terrain does change, and seamounts can change in size and even location.
acoustic mapping is about signature profiling a platform, its quite complex, but to manage the emissions on your own assets involves either passing the platform through a 360deg array (min 270deg) or in the case of a couple of other solutions, driving a partial conformal array over the hull and then mitigating the spikes through phyical engineering, or electronic means.
a geo ship is limited in what it can achieve wrt to subs. even with ROV’s there are limitations, but the bulk of floor mapping is done by surface vessels, be they controllers or mappers in their own right.
if you don’t have correct floor mapping you can break things. the USN, PLAN and Japanese MSDF all being very recent examples of how drivers can inadvertently break their boats.
Hmm that’s interesting because I have not heard that sea mounts can change their positions. I guess it would depend on the level of tectonic activity right? Is there any difference between smaller ocean like East Sea (South China Sea) than say Pacific Ocean? What is the major difference in submarine warfare in a Blue Water area compare to Brown Water area?
Acoustic mapping signals will be built into a database type for the use of passive sonar right? You mean it’s difficult to do acoustic mapping because it’s difficult to manage your own ship emission that’s conducting the survey?
Can you use less abbrev since I am not in the military and it could be hard to understand at time. For e.g what does ROV mean?
I am really curious about the level of preparatory work needed to be able to use submarines effectively since my country is preparing for a fleet of 6.
Thank you,
