As a minewarfare vessel, the Lindau class has probably outlived much of its usefulness. Ultimately, the SAN hope to use the Project Biro OPVs for mine-warfare: ship a containerised mine-warfare control centre on the Biro OPV and then find and destroy mines by combination of unmanned vehicle and diver. There are a few problems with that:
1. Biro OPVs won't have the wooden hull or special propulsion of the current Um-class mine hunters, making them less great for minehunting;
2. they also won't have any sweep gear, so they won't be able to sweep for mines at all
The navy will probably say that the new unmanned vehicles they want to get for Biro helps solve both my objections above, but I don't know how. Does anyone know?
But I always thought they should keep one or two Lindau class ships for training.
The SAN have had problems training and retaining bridge watchkeepers (officers certified to "drive" the ship) for as long as I can remember. If we have enough these days it would really surprise me. So I would say put one in service as a training ship, man it with an OC, first lieutenant and two or three more officers, engine room staff, a few senior rates and two cooks and leave space for about twenty midshipmen. Then you send them cruising up and down the coast giving the middies time to clock up their hours and complete their taskbooks. They can also do some fisheries patrols on the way.
And one last thing: forbid the mids to even look at the GPS! Navigation by visual and astro means only!
