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.

8 will be of this version

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.
