REMUS is equivalent to RNZN's Moa class IPBs carrying side-scan sonar for Q-route survey. Denmark's MSF1 class do carry side scan sonar and can be remotely operated. It was existing there for a decade, but RN did not considered it as a replacement for Hunts. Why? I
suppose this is because the level of survey a side-scan sonar can provide is much less than the sonars onboard Hunts/Sandowns can. Having REMUS is very nice thing. I love it. But, it is NOT REPLACING Hunts/Sandowns. I admit this is
guestimate, but I do remember RN's less enthusiasm against side scan sonar, when many of minor Navies are struggling to use side scan sonar as a "cheaper solution for MCM".
In short, my point here is, comparing REMUS and Hunt/Sandowns is not fair. In that case, you should compare Danish MSF1 vs REMUS. Yes, REMUS is more cheaper. Good. But, here we are talking about Hunt/Sandown replacements, not Danish MSF1.
A sonar is not going to cost £40,000 and hour to operate though. There is no way it is going to be as expensive as a big ass hello full of people hovering in the air. The Americans boat is big too, much bigger than anything we could reasonably deploy from a T31 or T26.
The Americans are aiming to operate the final ACTUV for £20,000 per day. Even if they swing and miss with it costing 200% that, it will still be 24 times cheaper to run than the Merlin.
I really hope you are right = ASW USV will be so cheap. Two thing to comment here;
- more than half the cost of Merlin HM2 is on its ASW suits and the rest is airframe, I think. If you are asking for the USV to have the same "ASW sensor" as a Merlin, you need to pay for it. Remember Merlin HM1 costed 97M GBP each (sorry it is from T23 wiki), while AW101 cargo helicopter is reported to cost less than 20M GBP.
- Merlin's helicopter nature (being fast, can dip sonar in many places) is different from ASW-USVs nature (permanent existence). I am NOT against ASW USV. I am just saying it will not be cheap.
I admit, for both MCM kit and ASW kit, my cost estimate may be a bit large = too pessimistic. But, I can NOT foresee being it "less than half" when you require the same level of operation.
It will almost certainly be cheaper than Merlin, which is a massive complex bit of kit, which also has to fly. Complex systems are indeed cheap, but going unmanned created huge savings. Autonomy is being pushed from the commercial world to reduce costs, the equipment already exists in the off shore industry, and is used regularly to reduce costs. Although autonomy is expensive, skilled humans are way more expensive, and often worse at the job
No objection here. I am just saying it will not be THAT cheap.
