Anyway, I came across some information in another forum that the estimated price tag for this project was 95m Euro (for two vessels). Just wondering if you have any further information (ie. length, draught, crew complement, speed, range etc.)? There doesn't appear to be anything on the Fassmer website as yet. As you say, they look very similar to the Type 748 Schwedeneck class.
For the two SVK boats only their length - 50m - has been published; the requirements list - in which all those details are - has always been classified and was only provided to accredited bidders. The ships are built to civilian standards. For displacement scaled from similar-design vessels from Fassmer (both larger and smaller) they will probably end up at around 840-850 tons.
For similar designs from Fassmer you'll have to look in the "research and survey vessel" section of their portfolio, in particular the two Fugro Marine Services requirement concepts they adapted onto their own pre-existing 42m hull design as well as a 65m variant (Fugro also had Damen adapt that requirement concept onto a 54m MRAV hull). I wouldn't expect SVK with specs - and even then with lots of "classified" - to make it on their website before the first one is commissioned.
I would assume crew numbers for basic ship operation to be somewhere around 6-10. Propulsion will definitely be diesel-electric, if they were "exotic" (e.g. LNG) they would advertise it.
Fuel reserves for range on such ships should be heavily adaptable to whatever the customer requests. The Fugro 65m vessels do nearly 9,000 nm at 10 knots to facilitate global deployment for their business. For the two SVK ships now ordered i doubt the range or endurance will be all that big - they are laid out to support trials primarily in the Baltic Sea within the rather small German EEZ, you don't need more than a week endurance and perhaps 2,000 nm range at decent speed for any scenario that they may be used in.
The Navy plans to acquire six larger 65m vessels probably of a similar configuration under the moniker SVS ("Sea Trials, Sea" vs SVK = "Sea Trials, Coast"). Those would then be intended for longer multi-week deployments over longer distances (primarily in Norway, to be exact). Tender for that hasn't been issued yet.
Ships of WTD71 have a notional wartime reserve coastal patrol boat role (earmarked since the 70s), and that space marked out on the forecastle looks sized about right for rapid installation of a MLG27 light gun for this purpose, of which the Navy Arsenal should always have a couple spare. Integrated EO sensor and laser rangefinder, single self-contained console - perfect for that kinda thing.
Given that they are to support submarine operations and torpedo trials they should have some sort of sonar btw, even if it's just one of those echosounders you hang overboard.
The 95.08 million Euro is the cost they ended up at for the two ships; presumably this includes some sort of support/maintenance contract and spare parts package though. The
originally envisioned budget for the ships was 30 million Euro and was presumably based on the cost for the Research-Ministry-financed "Uthörn II" ship from Fassmer (14.5 million), which is pretty much the same design in a 36m variant and a rather recent contract - they just laid her keel last month.
