The Istif-class is a true milestone that has proven the maturity of the Turkish naval industry. However, if we want to become a true and fully independent blue-water navy, instead of simply extending the current design to create the Istif Batch-II after completing the production of eight units, we should move toward a new frigate design. This platform should have a displacement of around 5,000 metric tons, featuring a wider beam to offer seakeeping and endurance comparable to the TF-2000 air defense destroyers, along with a minimum VLS capacity of 32 cells. Although it may not be apparent right now, in about 10 years it will become clear that this is just as critical a need as the TF-2000 class.

Unlike the TF-2000, its propulsion system, acoustic isolation, and hull engineering must be designed with a direct focus on the Anti-Submarine Warfare (ASW) role. This frigate should be equipped with a Thales Sonar 2087-equivalent heavy towed array sonar, a state-of-the-art hull-mounted sonar, hangar space for at least two helicopters, and advanced countermeasure and Anti-Torpedo Torpedo (ATT) capabilities. The expertise in system maturation that our domestic defense industry has attained in ASW naval systems has, in fact, paved the way for us to develop and produce one of the world’s most advanced ASW combatant platforms. The biggest obstacle to the development of such a heavy-class ASW frigate is already on the verge of being overcome.

Türkiye aims to establish a Blue-water Navy capable of maintaining a presence and conducting active operations at 2–3 distant naval bases simultaneously, while focusing on transoceanic missions with one massive or two medium-sized task forces. Lighter platforms in this structure will seek to protect territorial waters by transforming the 'Blue Homeland' (the Aegean, Mediterranean, and Black Seas) into an Anti-Access/Area Denial (A2/AD) zone. This will allow heavy-tonnage, high-endurance platforms to serve the nation’s interests in distant maritime regions without leaving the homeland vulnerable.

The high volume of platforms is a logistical necessity dictated by rotational dynamics and geographical dispersion. Operating simultaneously across the Blue Homeland and distant oceans requires a deep operational reserve, ensuring that intensive deployment schedules, long transit times, and mandatory dry-dock maintenance periods do not deplete the homeland's defensive posture. Consequently, this allows the Navy to absorb the high wear-and-tear of transoceanic missions without creating security vacuums in its immediate maritime domain. This extensive fleet structure is driven by strict naval logistical realities, specifically the 'Rule of Three' in maritime operations. To maintain a continuous, active presence at 2–3 distant naval bases and sustain transoceanic task forces, a significant multiplier of platforms is required; for every ship actively deployed, at least two others must be either undergoing scheduled maintenance/overhaul or engaged in working-up training cycles.

The proposed Combatant + Patrol Fleet structure for late 2030s as follows:
  • 16 Coastal Patrol Vessels: (Tuzla-class – sensor capabilities enhanced post-MLU, focusing on Manned-Unmanned Teaming and self-defense)
  • 10 MCMVs / Patrol Vessels: (Aydın-class / New-type Mine Countermeasures Vessels)
  • 16 Fast Attack Craft / Fast Corvettes: (New-type FAC and Kılıç-II)
  • 14 Corvettes: (Ada-class, Hisar-class)
  • 8 Istif-class frigates: (The fleet's multi-role workhorses)
  • 8 Frigates: (The proposed new-generation 5,000-ton heavy ASW program - and Barbaros-class which will gradually change with this class in the future)
  • 6 Destroyers: (Tepe class anti-air warfare guided-missile destroyer, the plan of 8 units can be reduced to 6 in the first stage, for allowing 4 additional frigates)
  • 12 AIP Submarines: (Reis-class and MİLDEN-Ay-class)
  • 10+ Conventional Diesel Submarines: (Gür-class, Preveze-class in less, and newly developed pocket/midget submarines)

does anybody know if the navy will also order some auxiliary ships to support this build up. Maybe another derya or a couple smaller ones similar to the ones ordered by portugal

There will be an Akar class replacement sooner or later. Hopefully we'll see two sisters to complement Derya after 2030s. Hopefully 1+ Derya and 1 more Durmuş.

İçel, F-518 really have been the fastest of the three sisters. Already flagged up, continuing her sea tests. Should be delivered in a few months, surely before 2027.

According to @tyronnosurusRex the latest news on Barbaros Class MLU was that it was being extended to TCG Salih Reis (f246). As per his deductions, the 16 month work-around time per ship has been hindered due to excessive need for the use of these ships. So the important point is to find time to get the ships in to dock. Originally it was planned to bring each ship to the dock before the previous one completed it‘s MLU.

That proves the fact that we have a shortage of number of frigates and the naval forces at times are over extended.

Quote:

Activities under the Barbaros Mid-Life Modernization (BYÖM) project have commenced on the frigate TCG Salihreis (F-246).

During the commissioning ceremony for the submarine TCG Hızırreis, maintenance and modernization activities were observed underway on the frigate TCG Salihreis in the background.

BARBAROS MID-LIFE MODERNIZATION (BYÖM) PROJECT:

Under the contract signed in April 2018, the project aimed for deliveries to take place between 2022 and 2025, with one-year intervals between them.

The project targets a 16-month modernization period for each frigate. This timeframe is planned to consist of 4 months for the removal of old systems, 4 months for the integration of new systems, and 8 months for harbor and sea acceptance tests.

The first ship, TCG Oruçreis, entered the shipyard in January 2022, and the process was completed in December 2024.

Delays in delivery schedules can occur because the ships may enter the shipyard later than planned due to heavy operational commitments.

According to the most recent information—specifically the Turkish Naval Forces Command's activity report dated March 2025—the following details regarding the BYÖM project were noted:

"Our Barbaros-class frigates are undergoing a comprehensive mid-life modernization. The modernization of the first ship, TCG Oruçreis (F-245), was completed in December 2024, and the modernization of the remaining three Barbaros-class frigates is scheduled for completion in 2028." Following modernization, the service life of the four Barbaros-class frigates—which have become among the highest-performing and most modern platforms in their class in the Mediterranean in terms of sensors and weaponry—will be extended into the 2040s.

Salihreis MLU probably started a few months later, november-december. She had an MRO first for 1-2 months.

I adore TCG DERYA as the ship has 360 degree 2 x CIWS cover.

Good to see my wishes in active warships.

Also I would love to see some UMTAS missiles against USV.

Türkiye has a vision for a nuclear-powered submarine that will be on the agenda in the 2040s. On the other hand, sooner or later, it will need an electromagnetic launch system for the aircraft carrier which construction has already begun. Going into a more speculative area, the Turkish navy may develop a need for heavy-class ASW frigates over joint program. Within the framework of the Trump administration's vision to support the pace of naval modernization and capacity building with allied countries, if Turkiye becomes one of the partner countries, we could receive accelerating support for some national programs within a framework of mutual benefit.

But considering our standing in the Senate and House I think the outlook for that kind of cooperation is bleak. I very much doubt that we'd be building ships for our own Navy at all. And building to strengthen our adversaries who may en up using it against us doesn't sit well with me.

Especially considering where US is going. I'd say we are in need of every Vessel leaving those shipyards, especially considering how TN has been stretching its capabilities due to insufficient vessels.

We need export contracts for our own industry and we would be building new designs for the us navy either fully or just parts. This deal or agreement would not reduce US security.

“Izmir Shipyard to Produce Warships Again

Izmir Shipyard Commander Rear Admiral Korkut Şen announced that production of the Offshore Patrol Vessel (OPV) is targeted to begin in 2028 following the completion of ASFAT investments.

While delivery of the first vessel to the Turkish Naval Forces is planned for 2030, the shipyard is also aimed to contribute to the National Attack Boat Project.”

FAC will then be divided between private and state shipyards. Guess they want more export contracts to fill the margins
