What is a Test Block?

A test block is manufactured and built prior to the actual submarine blocks, to test construction tolerances (shift from the actual circle), welding quality, welding distortions and heat affected zones. Also testing post-welding strength of the material and consistency of the construction rigs. Primarily a plain structural part of the pressure hull to ensure that it is suitable for bearing the crush depth. However, the section is less likely to be submerged.

There has been quite many of the tests prior to this, can't tell exact numbers but both welding material, base material (high yield class steel) and support rings and sub-assemblies had gone through tests.

Now it is finally time to ensure the rigs can manufacture as near as perfect circle pressure hulls with least amount of residual stress and deformations, with acceptable welding quality. The test block may also be used for later constructiones unless that it has been scrapped for some of the tests.

The test block has been in construction for weeks, or months, yet they are announcing it now.

So this one is new Hisar class OPV ? İt looks like smaller version of istanbul class with in front VLS .

Yes, with as many as possible Aselsan components (light ESM, STAMP, Sonar, Torpedo countermeasures and et al.). 8 will be of this version, however contracts are signed for 2 + 2 options, by two shipyards. Dearsan (leading Ozata and Desan for all contract stage), and Istanbul Naval Shipyard.

Let's see if we can offload the second ship to Croatia.

They signed a contract for the remaining four ships with ASFAT at IDEF

Asfat has no shipyard, they are the contractor - wrapper for Istanbul Naval Shipyard.

For me having a domestic sub with VLS and AIP is a one of the 4 strategic pillars among our current projects with KAAN, AC and TF 2000.... which will represent the pinnacle of technology level we have achieved so defintly worth waiting

Dont forget missile technology.

i know i just wanted to say that at least 6 are under contract to be build, 2 are under construction with dearsan and 4 are to be decided and an option for 2 more.

Plan is a big word. They only requested a budget for a single ship so far. In the future as they need it, maybe, but nothing for now.

I hope Milden uses solid-state batteries. First-generation solid-state batteries are now being sampled and are entering pilot production. Companies are setting up serial production lines. Even the first-generation solid-state batteries offer 400 Wh/kg energy densities and superior robustness and reliability. Assan's hybrid propulsion system uses a semi-solid state battery. You can buy a semi-solid state battery right now it is on the market.

Just a concept for FAZ II

No, who makes this up?
This is one of sensor suite integration studies carried out by Aselsan / Armerkom.

Dearsan MHV 80 will not have nonmagnetic steel.Mine countrmeasures can be performed from far distances with auvs,uuvs so there is no need to close the dangerous region and nonmagnetic steel,it would be also cheaper.Hisar class OPV 99 regained aselsan hızır torpedo countermeausure system,if aselsan düfas is added this ship would became a pure antisubmarine warfare ship,with bow mounted yakamos sonar,düfas,antisub helo,orka lightweight torpedos,roktetsan rockets assisted underwater bombs,and with the fruit of electric propulsion system.Tree of this ship working in harmony,multistatic sonar systems,will be submarine killer task group.

Does anyone know if Cenk 200 will be enough for hisar and atmaca

The brochure exactly tells the opposite, it will be built with non-magnetic steel.

For the 'enough' part, only Navy could tell after several tests, and Atmaca doesn't necessarily uses radar engagement / guidance unless that it is within visual ranges, which is very well covered by CENK-200.

I have a feeling that they might end up getting CENK-300 on all OPVs, especially after getting a VLS installed. We should be more concerned that installed FCRs are the low-end member of AKR family and lacks illumination as opposed to AKREP-300-N.
