While we are talking about SLBMs on 3000 ton subs, TF-2000 design process is still not complete and production is seemingly a long while away from beginning in phase 2.

"TF-2000 Phase-1 activities continue at the Project Design Office of the DZKK. Within the scope of the project, model experiments, classification, 3D production modeling, degaussing, main propulsion system, combat management system integration and design activities continue. As a result of the decision taken by the Defense Industry Executive Committee on May 13, Phase-2 activities will also be carried out by ASFAT."

Wasn't first ADA built this way as well? If I remember correctly, design has been finalized during construction.

As first ADA class, I guess Navy felt need of securing commitment to the TF2000 project if they chose to to go this way.

As first ADA class, I guess Navy felt need of securing commitment to the TF2000 project if they chose to to go this way.

In the first phase, the Naval Forces Command (DzKK) conducts the design work. In the second phase, shipyards like STM begin producing the vessel and make necessary improvements during the production process. The first vessel's production takes a long time, but after delivery, the shipyard meets the requirements and completes subsequent vessels in much shorter timeframes.

For example:

• TCG Istanbul: As the first vessel, it was delivered in 7 years including the design process
• TCG Izmir and TCG Izmit: These vessels from the same class will be produced in only 3 years (2026 delivery date)

The TF2000 project will follow the same process. The first vessel's production will take a long time, followed by rapid deliveries.

• TCG Istanbul: As the first vessel, it was delivered in 7 years including the design process

Istanbul was delayed by years because design and foreign components were changed considerably while it was built. TF2000 doesn't have the same problem.

Gabya-Class Frigates Get Atmaca Anti-Ship Missiles | TURDEF

Gabya-class frigates (Ex Oliver Hazard Perry-class) of the Turkish Navy alongside two other ship classes will receive the Atmaca anti-ship missile.

turdef.com

Four modernised Gabya Class frigates to receive Atmaca missiles in place of their old and shorter range Harpoons.

This means that these four ships will be with the fleet for a while yet.

Within the project, 3 Ada corvettes and the remaining Barbaros Class ships under MLU will also receive Atmaca as their anti ship missiles.

The project to be completed by Q1 of 2027

This project was signed in 2022. We are still yet to see any ship other than Adas, Istanbul or Oruçreis MLU with Atmaca.

Deliveries in the program are to be concluded by 2027.

Btw, 11 platform will receive Atmaca SSM

Yes but still first vessel is always a prototype/ learning experience
My guess is first vessel in service by 2029-2030

Considering design phase still continues and phase 2 was only signed for 2 weeks ago, I expect 2032 at the earliest. Wish they go for a private interim design that won't need the Istanbul shipyard to be built as a stopgap between Istif and TF2000.

As the second ship of the Pakistan MİLGEM project, PNS KHAIBAR—built at the Istanbul Shipyard Command under the main contractorship of ASFAT—set sail for the first time, it was accompanied at sea by our first Offshore Patrol Vessel, AKHİSAR, which is currently undergoing sea acceptance tests as part of the Offshore Patrol Vessel project.

MURATREİS, the third of the six Reis class submarines whose construction continues at the Gölcük Shipyard Command of our General Directorate of Shipyards, was launched on the 572nd anniversary of the Conquest of Istanbul.

Within the scope of the project, the bow section “Section 50”, which contains Turkey’s first domestic submarine torpedo tubes (main weapons), which we developed at Gürdesan under STM engineering and coordination, will also serve on MURATREİS.

TEI Wins U.S. Navy’s LM2500 Power Turbine Maintenance Contract

Turkey’s leading engine company, TEI, has won the maintenance tender issued by the U.S. Navy for the power turbine modules of LM2500 engines. With 40 years of experience in the field of aviation engines, TEI signed a depot-level maintenance contract for the gas generator modules of LM2500 engines with the U.S. Navy in 2024, with a ceiling value of $45.6 million. Following this, in the second quarter of 2025, TEI signed a new depot-level maintenance contract for the power turbine modules, with a ceiling value of $67.5 million.

TEI successfully carries out the maintenance and repair operations of the LM2500 gas turbine engines used by both the Turkish Navy and the U.S. Navy — which owns the world’s largest LM2500 fleet — at its advanced technology facilities in Eskişehir. TEI has reached a high level of technological capability and skilled workforce to provide maintenance and repair services for LM2500 engines used by many countries. As a result, TEI has become a globally preferred strategic maintenance center, ensuring the sustainability of propulsion systems of frigates, corvettes, destroyers, and amphibious ships. The U.S. Navy’s choice of TEI — a force known for its high operational capability — once again proves TEI’s reliability and technical excellence in the international defense industry ecosystem.

I hope our navy got something from recent events; firstly gökdeniz system shouldbe effective against small size drones,if not we must work on software or hardware especially radar system,secondy one gökdeniz on the ship can not cover 360 degree, so if possible use two of them, if not you can convert 25 mm aselsan stop system to 25 mm atom system,and distribute to places to cover 360 degrees. Single barrel gökdeniz have better elevation than double barrel.

Financial stop-gap is Aydın-class tonnage minehunter ships to be built at Istanbul Shipyard. Yes technically they are the only shipyard experienced with processing non-magnetic steels and Voith's VSP propulsion system. However a true stop-gap seems impossible at the moment.
Despite of being not a big fan of foreign procurement, i don't neglect Type-31, or Babcock's AH140 furbished with Turkish components as far as possible and commonalized with other subsystems present in Ada-Istanbul Classes. Babcock is very eager for licensed production, or leasing out the design license for further modifications. Until TF-2000 catches a pace, design offices may focus on redesign of AH140.
A private shipyard can easily carry this out.

The submarine revolution: lithium-ion battery system for a better performance

The submarine revolution: lithium-ion battery system for a better performance

www.thyssenkrupp-marinesystems.com

A good article about why Lithium batteries are better choice for diesel powered submarines.
Japanese naval top brass have already listened to their submarine captains‘ requests that the subs need to move quickly and fast to get out of danger areas, by building the last two Soryu Class subs, then the Taigei Class with Li-Ion batteries instead of AIP system. The Li-Ion may not give the submarines the 2-3 weeks underwater time AIP subs enjoy. But nevertheless the Li-Ion battery powered subs still manage up to 10 days’ underwater sailing. Also they are not restricted to 4-6 knots speeds like the AIP ships. They can be propelled to above 20 knots, and can sustain this speed for long periods. They also have much lower maintenance requirements.

May be we should take a page from the submarine books of the Japanese and the Germans who accept the advantages of Li-Ion battery usage in submarines, and apply it to our MILDEN submarines.

Then the classic question, how about Dearsan F142?

Whats are the advantages of gettting AH140 instead of F142? Wouldn't we have much more leeway about customisation if we go with F142? Also gettint a Turkish design would be much better for our naval industry?

On they seem to have similar specs but F142 seems to get neglected(or ignored. Experts doesn't like to talk about it whenever it gets mentioned) so I am wondering what is wrong with it?(is it the design or Dearsan itself, or this will make Dearsan much more powerfull than rest of the shipyards etc)

F142 is nothing more than a concept that Milgem DPO may sketch in a week at most (and will definitely be based on TF2000). What takes most of the effort and time is the latter stages of the design. Moreover F142 lacks the deck space and internal volume that Babcock 142 offers.

As any other non-nucler submarine experience, speeds above 10 knots is not economical or sustainable and only used if submarine is concluding that it is detected. Regardless of the battery, it is the electric motor tech that assures efficiency at higher speeds and still not sustainable for more than few hours. In overall Li-Ion batteries provide a longer endurance at economical speeds.
As far as i know Milden will be equipped with Li-Ion + AIP.
