Re: Japanese built frigates also for mine countermeasures
only problem is that instead of mine warfare ships also being available for other uses, main frontline units which are way too few in number anyway will be required for mine hunting!
Very nice, thanks. Interesting indeed. Looks to be sort of a shallow water version of SOSUS. That's what I thought of first thing, anyway.
Good stuff, Lars and Ralph.
I saw an interesting video on MCM/ASW project the USN tested from the late-1990s that relied on remote sensing for MCM and ASW called DISTANT THUNDER.
This video was made by an ex-USN sonar guy who served on USN attach submarines and is very informative.
For sure, adding such drones on more versatile ships, avoids the costs of building specialized MCM ships.
There are currently three strategies in different navies:
a) adding MCM equipment to frigates (high-end warships, US and Japanese navy)
b) adding MCM equipment to OPV (low-end naval ships, see Australian navy, see also the Canadian Kingston class)
c) building specialized MCM ships (e.g. Belgian, Dutch, and Finnish navies, probably also the French)
For sure, a) and b) are cheaper than c) if considering the costs of the complete fleet. In case of war, a) can defend itself better than b) or c) and protect its drones used to hunt mines.
I do not think that the drones are the new aspect. They exist for some time - for sure, they are getting better. The new aspect is the building of multi-purpose ships, which include also MCM as one of their functions. E.g. the use of specialized mine-hunting sonar in a multi-purpose frigate.
