@anmdt Could you please enlighten me:
1)Within how many miles from the coastline, The YTKB are used for inshore tasks ? 100 miles is realistic?
2) how many patrol days per year each vessel is intended to achieve? 300 days per year is possible?

I don’t know what the intended regular usage frequency for these vessels are. But I can see 2 Tuzla class ships from my balcony and they hardly go out. May be once a month? Even the 2 mrtp33 that are there, will go out at most once , sometimes couple of times a week.
Away from coastline distance, is governed by the sea state they will be operating in. FAC55 has a range of 750-1000Nmiles depending on at what speed it is used. So if there is calm seas, then there is nothing stopping it going 300 nautical miles out in to the sea. But these boats become difficult to see if they take high coastal mountains behind them and attack at high speed at the incoming enemy vessels. So out in open seas they lose that advantage. So they are more effective lying low in coastal bays and attacking.

From Sarıyer i saw two YTKB one leaving another coming back to Beykoz base. Third one was anchored in the port. AFAIK they are used immensely 300 patrol day per year.

In an interview today, Ukraine's Minister of Strategic Industries Oleg Uruskiy: "4 (I MILGEM) corvettes will be produced, one in Turkey, three in Ukraine (Okean Shipyard). Our Ministry wants Zorya-Mashproekt gas turbine engines to be used in corvettes.

Amazing opportunity for Turkish Navy to test the Ukrainian engines and earn capability to integrate them to Milgem platforms.

I would say within EEZ-Shallow waters
for patrol operations.
I am not sure how frequently the platform is being used but from what i know it has active time more than half a year.

Wonder what happened to 2+2 agreement, it makes sense for at least 2 ships to be built in here so their personnel can be trained.
Best bet, turkish subcontractors will be working in Ukraine in construction,they don't have sufficient number of naval architects and field engineers to handle the project.
Ukraine engines were considered earlier for Ada class to make an optional offer to other countries, wonder who didn't want to cooperate then.
And probably STM will handle whole integration process of the gas turbine this will introduce a valuable know-how, but then it will have to be a CODOG and i am not sure if a single ukranian gasturbine outperform the earlier CODAG. They will have to switch to 2+2 configuration which will require major modifications.
I doubt if the engines get larger it will compromise the fuel capacity thus the range.

Different Zorya engine have to be used for Ada-class but some info

The first to use GT-25000 gas turbines is the 052C destroyer, which uses 2 GT-25000 gas turbines + 2 MTU diesel engines for diesel-fuel alternate power (diesel engines for low-speed navigation and gas turbines for high-speed navigation), making 052C/D The maximum speed of the type destroyer can reach 30 knots, if it is diesel-fuel combined power, it is estimated that the speed can reach 32 knots!

Since China and Ukraine signed the "UGT-25000 Gas Turbine Production License and Single Engine Sales Contract", Ukraine sold 10 UGT-25000/DA80 gas turbines to China and transferred related technologies. China made localization of the main naval surface ships. Embarked on the road of alternate diesel-fueled power supply.

Since the air flow, volume, and weight of UGT-25000/DA-80 gas turbines are greater than those of LM-2500, they cannot be directly used in the hull of the Type 052 destroyer. The military industry has developed the 052 modified destroyer with its power system. They are the 052B destroyers 168 and 169 with a full load displacement of 5850 tons, and the 052C destroyers 170 and 171 with a displacement of 6000 tons.

When introducing UGT-25000/DA-80 gas turbines from Ukraine, the Navy already has advanced experience in using American-made LM2500 gas turbines. Based on the Navy’s experience, military industry has made a series of improvements to UGT-25000. The cover adopts LM2500 box type. The gas turbine is completely covered, the noise and temperature of the engine room are reduced, and the working environment of the engine body is improved.

In addition, an observation window is installed on the box to facilitate the staff to observe the status of the gas turbine; lighting and other systems are installed to facilitate the staff to troubleshoot the system; the exhaust pipe and the gas turbine are installed on the same base, which fundamentally solves the problem of easy aging of tracheal rubber.


UGT-25000 itself is a civilian product. The first three models are DG80, DN80, and DU80. DA-80 is a civilian-to-military product. Ukraine has increased the thermal efficiency to about 36%. This indicator has been compared with the LM2500 of General Electric Company in the same period. The gas turbine is flat, but the weight is multiple of LM2500.

In contrast, UGT-25000/DA-80 has a power output of 28,000 kilowatts, which is even 44.9% higher than the 19,800 kilowatts of LM2500.
For gas turbines, which are already very light power machinery, they can guarantee thermal efficiency. Under the circumstances, a few tons of weight gain does not matter.

For the Chinese Navy, due to the hindrance of the import of LM2500 gas turbines and the inability to reverse imitation due to reasons such as intellectual property rights, UGT25000/DA-80 has become the best choice. Although it is not advanced, it is at least usable and gives the Navy The newest 055-type 10,000-ton large drive, which has a high speed of more than 30 knots, can provide the best solution to the problem of insufficient power that has dragged down the tonnage and aspect ratio of ships for many years.

Addition

I couldn't find it but there was a blog claiming UGT25000 under performed in hot tropical climate (South China Sea) so engine had to go through improvements.

Also Ukrainians did not know how to integrate the engines to modern navy ships.

Thanks. What about corvettes and frigates? Maximum How many day they could be active? Also half in year?

Comparing our frigate with 10 latest modern frigates, i can't find any deficiency. Design appears to be neat and flowless.

View attachment 12598

Cost/Performance might be so good that I can see Navy wanting 4 more if it can be financed. Hopefully with nationalized weapon systems, electronics and Lodos-Zorya engine.

I have told this nearly 4 years ago. :)
A different subcontractor has conducted bow form optimization of I Class.
3-4 th ship of Ada Class has slightly different bow form as well.
I doubt if it can be called wave piercing, but it is optimized to reduce spraying, thus increasing efficiency in higher speeds.
Also, a different bulb type was adapted, compared to Ada Class. Jinnah Class will have different bow form as well.

Last ship to be finished in 2027 then testing so hand over in 2029. Another 12 years for 4 ships. Incredible, with this speed TF-2000 project will be done in 2050.

You would think they would learn from the Ada fiasco but apparently nobody bothered. How is it that a country of this size, bordered by water on every single side can’t manage to build 2-3 ships in short intervals after another? This project should have be concluded in 2025 the latest. What are our shipyards doing?

How is no one sitting in higher positions bothered by this?

What happened to Demir‘s statement about having private shipyards build the remaining ships parallel to each other? Was that a nice lie?

I honestly am fed up with this and how no one seems to care that a country like Turkey needs 12 years to build light frigates for its navy while other countries build the same amount of ships in half the time. Incredible. I don’t even want to hear so poor excuse for this fiasco.
