We knew for some time Dearsan was awarded the next 4 Hisar Class OPVs

Per Naval Insider claim, next 4 Hisar Class OPVs are to be named as followed: "Sultanhisar (P-1222/TBMC), Yarhisar (P-1223/TBMD), Demirhisar (P-1224/TBME), Sivrihisar (P-1225/TBMF)"

All 6 names are 1/1 lifted from the 1960s Hisar Class patrol ships, and of course previous ships beforehand.

In the same vein, Aselsan signed a deal worth €210 million contract for "Electronic Warfare, Radar, Communication, Navigation, Weapon, Electro-Optic and Underwater Systems for naval platforms", with Dearsan-Desan-Özata shipyards, who I believe are responsible for this program. "Deliveries will be completed between 2025 and 2029."

Pretty long lead time of 4 years which makes me think the 2+2 is not an option per se but there will be some years between the two deliveries. Aselsan takes the cake for most of the equipment on the ships, which comes down to 53 million dollars(52m €) per ship. Must be pretty cheap.

Is there a possibility that MCMV will also be included in the contract?

From what's put out I think Dearsan handles the MCMV by itself, unlike the Hisars with "Dearsan-Desan-Özata". Contract announcement would likely mention it separately.

Akbaba claims Dearsan will build two while Desan and Özata will build one each. All in all, this brings the shipyards that have built/will build a Ada hull ship to I believe 10? TAIS, Istanbul, Istanbul Naval, RMK, Dearsan, Desan, Özata and KSEW in Pakistan. What a design.

Yes, it is correct, but 2 of the ships are still optional. Actual order is only for first two.

Possibly first two will start construction at Özata and Desan, Dearsan's slipway is occupied with Qatari FAC and MCMW ship.

What I found out recently;

Initially Aselsan signed a $40 million agreement with ASFAT, probably for two ships. Now it is about $50 million per ship.

The increase can only be explained by the inclusion of additional sensor systems, ESM, stabilized turret, sonar, etc. We can see PIRI IRST on the new hulls.

That's very interesting. Wish we had some more clarity on construction and on the loadout. Let's see if the shipyards announce a contract with Roketsan soon.

@AlterUnd took some notices on Barbaros MLU and I-Class. $70 and $90 millions for Aselsan share, respectively.
We will see an interesting layout for the upcoming Hisar Class OPVs. Possibly DUFAS, Gokdeniz and even Compact EA / IRST.

TF-2000 will be a real behemoth...

Interesting news. Aspilsan's Hydrogen Unit manager announced his departure from the unit/company. Said unit was part of navy's AIP project for Reis Class and Milden submarines.

"Just a few days ago, we were rejoicing that the first welds for the first MİLDEN Submarine had been laid, but the Manager of ASPİLSAN's Hydrogen Unit, one of the teams established during the development of the NATIONAL AIP System, which will be used both in MİLDEN Submarines and during the Half-Life Modernization of REİS Class Submarines, is publishing a farewell letter saying, "At the point we have reached today, hydrogen is still unclaimed," after nearly 6.5 years of work."

It leaves doubts whether AIP system for Milden will come in time. One should also wonder if there's not a viable product yet, why did the Milden construction officially start last month? Maybe they are going for the Spanish route?

Could somebody explain what the hydrogen unit is and why is it so hard to achieve?

Could somebody explain what the hydrogen unit is and why is it so hard to achieve?

The process of creating H2 is complicated, saftey and storage are extremly important, H2 is highly flammable, toxic and if it escapes can even corrode metal.

PEM Proton Exchange Membrane fuel cell system is the technology behind the AIP system we have. This is a very specialised power generation system developed for power generation in submarines.
Below is a simple explanation of it.

A Proton Exchange Membrane (PEM) fuel cell, also known as a Polymer Electrolyte Membrane fuel cell, generates electricity through a chemical reaction between hydrogen and oxygen. Here’s a detailed explanation of how it works:

The basic components of a PEM fuel cell include the anode, cathode, electrolyte, and catalyst. The anode is the negative electrode where hydrogen gas is fed. The cathode is the positive electrode where oxygen gas is fed. The electrolyte is a proton-conducting membrane that only allows protons to pass through it while blocking electrons. The catalyst, usually platinum, is used to speed up the reaction at the electrodes.

The working principle begins with hydrogen splitting at the anode. Hydrogen gas is supplied to the anode, where, with the help of a platinum catalyst, hydrogen molecules are split into protons and electrons. The proton-conducting membrane, or electrolyte, allows the protons to pass through to the cathode while blocking the electrons.

Since the electrons cannot pass through the electrolyte, they travel through an external circuit, creating an electric current that can be used to do work, such as powering an electric motor. At the cathode, oxygen gas is supplied. Here, oxygen molecules react with the protons coming through the electrolyte and the electrons coming through the external circuit to form water.
The overall chemical reaction in a PEM fuel cell results in the production of water, electricity, and heat. This makes PEM fuel cells a clean and efficient energy source.

As oxygen is a byproduct it means longer underwater times. But still large amounts of O2 needs to be stored. You are also limited by the hydrogen stock you have. But still can stay submerged by 2 to 3 weeks.

Izmir frigate launched. A very important milestone for Turkish private shipyards

What a lovely day, what a lovely boat with a lovely name.

We can breathe a sigh of relief now. Private shipyards ensure full throttle hull production while almost all critical systems in the equiping will provide domestically. TF2000 is now our new horizon.

Exactly! Istif production going according to the plans. We should see Izmit being launched within few months as well.

New real challenge we face is the TF2000, which will be a lot harder and expensive than Istifs, but we can do it.

Did you noticed the VLS? It looks bigger than on the first I-class, seems like it will have MIDLAS strike variant or for larger missiles such as SIPER Blk2.
