TCG Kınalıada Is Launched And TCG Istanbul Is Placed On Slipway

The fourth and last ship of Ada class corvettes, F-514 TCG Kınalıada was launched today, after 8 years and 9 months since first indigenous warship TCG Heybeliada left the slipway.

Today also marked the start of a new era of Turkish warship construction. The first module of  the frigate TCG Istanbul was laid on the slipway.

The first steel of the frigate was cut on 19. January 2017. The first model of the ship was constructed during the last 6 months. As Tuzla Naval Shipyard has only one slipway to accommodate new buildings, the launching of TCG Kınalıada created space for the frigate.

TCG İstanbul will be the prototype of the second generation of the Milgem class warships. There will be four of them: TCG İstanbul, TCG İzmir, TCG İzmit and TCG İçel. They are a modified version of Ada class corvettes. They will be about 14 meters longer but will have the same width as Ada class. The frigates will be 600 tons heavier.

Construction of TCG İstanbul is expected to be completed within the next 46 months with the intended commissioning date is 2021.

I wish TCG Kınalıada fair winds and following seas.

The Evaluation of TCG Istanbul’s Design

During the IDEF 2015 12th International Defense Industry Fair, Turkish Navy shared the first conceptual drawing of the second generation of Milgem class. There was a poster about TCG Istanbul on the Turkish Naval Forces booth during IDEF 2017 too.

I though it would be interesting to compare the photos and see how the design of TCG Istanbul has evolved.

Not surprisingly there are a few changes in design on the outside. Any changes made inside the ship remains elusive. The changes are focused between the bow and midships. It seems as the design of the ship from midships to aft has been found satisfactory.

The most important change is in the shape of the bridge and the mast.Lets look at them:
1. If the darker patches along the hull indicate openable hatches, there is a new hatch at location 1. On Ada class corvettes this area is used for replenishment. Since the design of TCG İstanbul is based on Ada class it is safe to assume that this area will be used for replenishment too. Thus there was a need to implement a hatch there to ease the operations there.

2. The location of the SATCOM antennas has changed. In 2015 there were located towards to the end of the mast. In 2017 there were moved a few meters to the front.

3. There are new antennas there. Their place and shape suggests antennas for an on board electronic warfare system. Probable a local development. The antennas of SATCOM and ECM are pretty close. I hope they won’t create any interference.

4. The photos are not quite detailed but the electro-optical tracking and detection system has changed. In 2015 it was round and ball-shaped like ASELFLIR 300D. In 2017 it has a distinct rectangular shape of Denizgözü-Ahtapot. So the old system used on Ada class corvettes and Tuzla class patrol boats was replaced with a new generation sensor.

5. The shape of the bridge, and the forward part of the mast has changed. In 2015 the forward surfaces had a more slanted slope. In 2017 the slopes are more steep. The roof of the bridge is also less clustered and has more clean lines.

6. The all closed bow guards rails has been modified. The newer version has a bow bulwark and open guard rails. This must have changed the stealthiness of the ship. But the trade-off between becoming a little less stealth and having a flexible forward maneuvering area must be important for the handlers.

The sensors with the exception of the EO system and addition of ECM system and the weapons seem to be unchanged.

TCG Kınalıada Coming Along Nicely

TCG Burgazada (left) is in dry dock and being fitted out. TCG Kınalıada (right) is still on the slipway. Her shape indicates all major constructing is almost finished. She seems to be almost ready for launching in September.

There are some interesting steel blocks lying just to the left of the slipway. They can’t be made for TCG Kınalıada since her shape is full and there is no room to add these blocks. Thus they must the first blocks of TCG İstanbul. They will be placed on the slipway once TCG Kınalıada is launched.

The fitting out of the third Ada class (Milgem) corvette TCG Burgazada is proceeding on the dry dock. The fabrication of the hull of the fourth and final Ada class corvette TCG Kınalıada is almost finished.

The pre-fabrication of the first İ class frigate is continuing. First two blocks of the hull is ready to be placed on the slipway once the last Ada class corvette is launched.

First Steel Cut For TCG Istanbul

On 19 January 2017, first steel was cut for the Turkish frigate TCG İstanbul in Istanbul Naval Shipyard.

Defence Minister and Commander of Turkish Naval Forces attended the ceremony that marked the construction start of Turkey’s first indigenous frigate.

TCG İstanbul will be the first ship of a class of 4 frigates also known as İ (or İstif according to Turkish Naval spelling alphabet) class. The others will be called as TCG İzmir, TCG İzmit and TCG İçel.

The conceptual drawing of this new class was first revealed during the IDEF 2015 International Defense Industry Fair.

The new frigate will be about 14 meters longer but will have the same width as Ada class. TCG İstanbul will be 600 tons heavier and have a deeper draft due to the increased weapon load and other design changes.

The main gun is a 76mm with a stealth cupola. There is 16 cell Mk41 VLS system just behind the gun, for ESSM missiles.

The form of the bridge and the main mast is almost identical to the existing Ada class only slightly enlarge. There will be a Smart-S Mk2 radar and ARES-2 ESM suit on the mast.

One important difference between the ships is the number of the anti-ship missiles carried. The weapon load on İstif class will be the double of Ada class with 16 missiles launchers. This is the twice the usual load of the existing anti-ship missiles normally carried on Turkish warships.

Another difference is the selection of the self-defence weapons. While the Ada class has the Mk49 launcher for RAM anti-air missiles the İstif class will be fitted with a Mk15 Phalanx CIWS.

A comparison between Ada and İstif class

The above mentioned are the external differences between the two generation of Milgem ships. The internal changes are very hard to tell at this time. But nevertheless, one might safely say that the combat management system of the second generation will be an improved version of the first generation.

The construction of TCG İstanbul is expected to be completed within the next 46 months with the intended commissioning date 2021.
