Kurtaran 2019 Submarine Rescue Exercise

TCG Alemdar. The main submarine rescue ship of the Turkish Navy.

Turkish Navy organized the third initiation of Kurtaran series submarine rescue exercises between 27 and 31 May 2019.

This year the submarines TCG Gür, TCG 1. İnönü and TCG Dolunay, submarine rescue ship TCG Alemdar, rescue and salvage ships TCG Işın and TCG Akın, frigate TCG Gelibolu, minehunter TCG Akçay, patrol boat TCG Köyceğiz, one P-235 maritime patrol aircraft, one SH-70 ASW helicopter from Turkish Navy took part in the exercise as well as one AS-535 Cougar helicopter from Turkish Army, one C-130 Hercules cargo plane from the Turkish Air Force. One P-8 Poseidon ASW plane from US Navy also participated in the exercise.

Turkish Navy operates one dedicated submarine rescue mother ship TCG Alemdar and two rescue and salvage ships TCG Işın and TCG Akın. All of them have taken part in the exercise. TCG Alemdar can act as mother ship both for NATO Submarine Rescue System and US Navy Submarine Rescue System if needed.

Kurtaran 2019 started on 27th May with the pre-deployment briefing. On 28th May the surface units and aircraft honed their skill in finding the 3 submerged disabled submarines (DISSUB) sitting at the bottom of the sea.

On 29th May, the first training was to render assistance to submariners who were forced to leave the DISSUB by rush escape. Turkish Navy Parachute Search and Rescue Team similar in function to the Royal Navy’s Submarine Parachute Assistance Group made jumps from a C-130 cargo plane to help these submariners. The team of 12 jumped in 3 parts as the plane made 3 passes over the submariners waiting to be rescued. The Parachute Search and Rescue Team quickly inflated several life rafts and biding them creating a support base. They have used the RHIBs to collect the submariners from the water and rendering the first aid at the support base. Later they were brought to TCG Alemdar.

There is a wide range of medical facilities on board of TCG Alemdar including one full functional operation room, one x-ray room, a five-bed medical ward, and two hyperbaric chambers. Each chamber can hold 22 persons. The SMERAT team performed a quick triage and treated the patients according to their injuries and sufferings. Those who needed to be transferred to a more advanced medical facility were evacuated by the Land Forces’ Cougar helicopter.

TCG Alemdar search with her onboard sensors for the DISSUB played by TCG 1. İnönü. After locating the submarine TCG Alemdar positioned herself over the submerged disabled submarine. Using her active position controlling systems the rescue ship was able to stay on the exact spot for the remainder of the exercise.

First, the remotely operated underwater vehicle TCB Istakoz 1 was lowered to the submarine. The ROV was constructed by a Turkish company and can operate up to 1000 meters depth. Following the contact with the DISSUB, a diver immersed to the submarine inside the atmospheric diving system. The diver in ADS brought an emergency life support store containing urgently needed supplies by the submarine. The diver placed the emergency life support store inside the submarines escape trunk located inside the sail. The diver in ADS also connected the down-haul cable to a special pad-eye on the submarine hatch. The cable was later used by the submarine escape chamber to align itself with the submarine and mate.

The McCann bell type submarine escape chamber was lowered to the submarine. This type of submarine escape chamber is old but proven technology and can be used for evacuating personnel from the submarine if the pressure inside the submarine is not above one atmosphere and the submarine is not deeper than 207 meters. The chamber descended to the submarine and mated successfully. Two submariners entered the chamber and it resurfaced.

This was the final training for the day. TCG 1. İnönü reemerged from the depths and both vessels returned to the base. While TCG Alemdar was training with TCG 1.İnönü, the other two ships TCG Işın and TCG Akın were also conducting similar activates with the other submarines.

On 30th May, the submarine TCG 1. İnönü bottomed at 30 meters depth. During this exercise, sailors left the submarine via the escape trunk, donned Mk 10 Submarine Escape Immersion Ensemble and surfaced freely. The units waiting on the surface rescued them.

The exercise ended on 31st May with the post-exercise briefing.

TCB Istakoz 1 is the name of this ROV. Istakoz means lobster in Turkish. I can only admire the humor of the godfather of this device. It has two arms with 7 functions. Two pilots are required to use this ROV. One operates the ROV, the other arms.

An Afternoon On TCG Burgazada

TCG Burgazada. The third Milgem class corvette.

TCG Burgazada. The third Milgem class corvette.

During the IDEF 2019 defense exhibition last week I had the privilege to visit TCG Burgazada.

TCG Burgazada is the third of the four Ada class corvettes. She was commissioned on 4th November 2018 and is the newest warship of the Turkish Navy.

Turkish Navy always considered the first two ships as prototypes. The lessons learned in constructing and using these ships were to be incorporated in the subsequent ships as there were under construction. Thus TCG Burgazada is slightly updated compared to TCG Heybeliada and TCG Büyükada, though these changes are subtle and mostly not visible from the outside at all.

One exception is the new Aselsan Seaeye-Ahtapot electro-optic sensor on the aft mast while the previous ships use Aselflir 300. Aselflir 300 was originally designed for airborne platforms and was installed without much modification. Thus the mean time between regular maintenance is quite short for a maritime system and the whole sensor must be taken down for the maintenance. These shortcomings are rectified in Seaeye-Ahtapot and the operators are quite happy with its performance. But Aselsan needs to come up with a better and catchier name.

The other changes are under the skin. The main machinery has 10.000 more horsepower making TCG Burgazada faster than the other Ada class ships.

TCG Burgazada has Aselsan made Hızır countermeasure system for torpedo attacks. She is the first ship to be fitted with this system. The system consists of two decoy launchers on both sides of the funnel and one towed array and decoy. Though the system is very similar to Ultra built torpedo countermeasure system used on the other ships I believe the logistics of a locally built system is preferred by the end user.

One could still get “the new ship smell” when walking through the passageways.

I wish fair winds and following seas to TCG Burgazada and her crew.

TCG Anadolu Has Been Floated

TCG Anadolu has been floated on 4th May 2019. It is important to note that it is a technical procedure and not the official launching of the ship.

TCG Anadolu is being constructed on a floating dock and the keel blocks under her hull need to be relocated. She will be taken back to the dock after the keel blogs have been relocated and the construction will continue.

The ship was floated 4 days after she suffered a fire. The fire broke out as some isolation material caught fire when welding was done nearby. Although there is no visible damage from the outside, the fire must have damaged the parts of the ship. Since the construction of the ship continues the repair of the damaged parts won’t be much difficult.

First Logistic Support Ship On Builders Trials

First, of the two logistic support ships, A-574 TCG Yüzbaşı Güngör Durmuş has started her shipyard trials. These two ships will be a welcomed addition to the existing fleet of tankers and replenishment ships of the Turkish Navy.

These ships do not have a rig for underway replenishment alongside but will be able to stream a fuel hose astern for a more old fashioned way.

TCG Yüzbaşı Güngör Durmuş is constructed by Selah Shipyard and should have been handed over to the Navy 18 months ago.

The Participants In Mavi Vatan Exercise (Part 2)

An update to the major units taking part in the exercise Mavi Vatan:

Legend: Green means confirmed participant. Red means confirmed nonparticipant.

Small landing craft and auxiliaries taking part in the exercise are not included in the list. For further information regarding the exercise click here.

Additional information:

Frigates: TCG Gökçeada is deployed with the SNMG-2 and TCG Geliblou is in Gulf Of Aden with CTF-151. One frigate is escorting the Barbaros Hayrettin seismic ship in the Mediterranean. This means all frigates of the Turkish Navy are deployed.

Corvettes: Two corvettes are also escorting the Barbaros Hayrettin seismic ship in the Mediterranean.  This leaves 8 corvettes available for this exercise. Only one will miss it out.

Minehunters: TCG Akçakoca is deployed with SNMCMG-2. From the available ten strong force, 7 will take part.

Submarines: As their nature, they are the most difficult units to identify. TCG Gür is in Italy to join the NATO exercise Dynamic Manta. Two more are deployed to the Eastern Mediterranean according to Turkish General Staff. 7 out of 9 available submarines are taking part.

Amphibious ships: According to pre-exercise briefing 22 amphibious ships are participating in this exercise. Most of them are smaller LCT and LCM sized landing craft.

Fast attack craft: Turkish Navy has 19 missile-armed fast attack craft. 16 of them are taking part in this exercise.

The Participants In Mavi Vatan Exercise

Regular readers of this blog will know, that I like to name the units that are taking part in an exercise. It is not easy to identify the participating units to the Mavi Vatan naval exercise. First, there are 103 units taking part in this drill. I would be able to get to name them all. Second, most of the attention of the media is focused on larger units like frigates and corvettes. The smaller landing craft and the auxiliaries taking part will not be covered.

Never the less I am trying to find the larger units participating in this exercise. Here is the list:

Legend: Green means confirmed participant. Red means confirmed nonparticipant.

Frigates: TCG Gökçeada is deployed with the SNMG-2 and TCG Geliblou is in Gulf Of Aden with CTF-151. One frigate is escorting the Barbaros Hayrettin seismic ship in the Mediterranean. This means all frigates of the Turkish Navy are deployed.

Corvettes: Two corvettes are also escorting the Barbaros Hayrettin seismic ship in the Mediterranean.  This leaves 8 corvettes available for this exercise. Only one will miss it out.

Korkut-D Air Defence System Remodeled

Left, a screen capture of TCG Sokullu Mehmet Paşa as she is transiting through Istanbul. Note there is no 100mm gun or the Korkut-D CIWS at the aft of the ship. Right, an archive photo of the Korkmaz on board of the ship from 2018.

Today TCG Sokullu Mehmet Paşa made a northbound passage through Istanbul. This ship was built for Germany Navy as FGS Donau, by Schlichting-Werft in Travemünde as a tender for fast attack boats. She was transferred to the Turkish Navy in 1995 to replace the old ship of the same name.

TCG Sokullu Mehmet Paşa was selected as a test platform for the Korkut-D close-in weapon system. In 2018 the 100mm gun turret at the aft of the ship on X position was replaced with a Korkut-D mount and a 3D radar mast. As the ship passed today the Korkut-D system was no longer on board meaning the test are officially over. It was interesting to note that the original gun mount was not replaced.

Left, the Korkut-D mount during the test on board of TCG Sokullu Mehmet Paşa. The fire control radar is on the mount while the 3D search radar is on a separate mast. Right, rendering of the remodeled Korkut-D mounts with and without the 3D radar.

It is quite easy to fit a weapon system to the ships which are on the design table. We will see Korkut-D on the future Turkish warships if the Turkish Navy is satisfied with the end product. But it is much more difficult to retrofit a new weapon system such as Korkut-D to existing ships. It should not penetrate decks, not worsen the stability of the ship and not add too much weight.

Aselsan, the manufacturer of the Korkut-D CIWS system seems to have remodeled the mount. During the tests, the original Korkut-D mount has only the fire control system mounted on the turret while the 3D search radar was on a separate mast. It was at the end of the turret and on the center as the guns were quite forward. On the remodeled turret, the fire control system is located to the left side of the turret and the guns seem to be moved a little to the back more towards the center of the turret. The new configuration will no doubt have shortened the overall length of the system making it easier to fit into smaller spaces and increased the possibility of changing the legacy close-in weapon system on older warships with Korkut-D.

TCG Ufuk Launched

The previously unnamed test and evaluation ship has now a name and a pennant number: A-591 TCG Ufuk.

The ship, the first one in Turkish Navy to bear that name, was launched on 9th February 2019.

TCG Ufuk shows a striking resemblance to Ada class corvettes. Even some main physical attributes like the length, width, drought of the ships are the same. Here is a comparison chart:

TCG Ufuk Ada Class
Length (meters) 99,5 99,5
Width (meters) 14,4 14,4
Draft (meters) 3,6 3,9
Displacement (tons) 2400 2300
Speed (knots) 18+ 29

Two most obvious differences between this ship and the Ada class corvettes are that that TCG Ufuk doesn’t have any weapons.  The test and evaluation ship does have a flight deck to support 10-tonne class helicopters but does not have a hangar.

According to news reports, TCG Ufuk will have an all diesel main propulsion whereas the Ada class ships have a combined gas turbine and diesel engines as main propulsion. The top speed is given as 18+ knots, which is considerably slower than 29 knots top speed of Ada class corvettes.

During the launching ceremony, the President of Turkey Mr. Erdoğan told that this ship was the first intelligence gathering ship built by national means and mentioned the importance of signal intelligence.

The intelligence gathering mission of this ship may explain why the ship will have a 100 tons more displacement compared to Ada class corvettes despite having no weapons and the sensors associated with fire control and why its construction was not published much compared to other defense industry projects.

The commissioning of TCG Ufuk is scheduled for July 2020.

Test And Evaluation Ship Takes Shape

A CGI image of the Test and Evaluation Ship showing her general configuration. The lack of weapons, the enclosure of the section between the funnel and the mast are particularly striking features.

 

The project was first made public in a presentation made by Undersecreteriat for Defence Industries, (SSM) during the 7th Naval Systems Seminar in 2017. SSM simply told that they have signed a contract for a Test and Evaluation Ship.

More information was released in a presentation made by the engineering company STM during the same event. According to STM, they are the main contractor of a project, where one Test and Evaluation Ship (TaES) will be constructed by Istanbul Denizcilik Shipyard. The ship will have hull form of Ada class corvettes. Aselsan, as a subcontractor is responsible for the manufacturing of the mission systems to be used on board.

STM also shared the above photo. The ship showed there has a striking resemblance to Ada class corvettes. Two most obvious differences between this ship and the Ada class corvettes are this ship doesn’t have a gun in A position and any other weapons. The space between the mast and the funnel, where 8 Harpoon missiles are installed in Ada class ships doesn’t exist in the TaES. The aft of the superstructure is also slightly different. The superstructure aft of the funnel is larger since the TaES doesn’t have the STAMP remote-controlled gun system and anti-torpedo countermeasures system, the deck on which these systems are installed is added to the hull.

According to news reports, the TaEs will have an all diesel main propulsion whereas the Ada class ships have a combined gas turbine and diesel engines as main propulsion. The top speed of the TaES will be lower than Ada class corvettes.

Since TaES shares the same hull and superstructure of the Ada class corvettes, I believe the physical measurements of the TaES will be same or very similar of Ada class ships.

On the left are the mast and forward superstructure of the first Ada class corvette TCG Heybeliada. On the right are the mast and the forward structure of the Test and Evaluation Ship. Although the shape is similar, the number of supports on the mast of the TaES is much more compared to TCG Heybeliada. Obviously, more sensors will installed on TaES.

The stern view of the TaES and TCG Heybeliada. The TaES does have a flight deck and a hangar. But the shape of the superstructure at the aft is different.

TCG Gökçeada Deployed To The Indian Ocean

TCG Gökçeda will start her goodwill visit to Doha, Qatar on 28th January 2019.

The frigate departed from Aksaz Naval Base on 13th January 2019 for a 3-month deployment to the Indian Ocean which will be her third. The frigate passed through the Suez Canal on 16th January and proceed to Djibouti her first port of call.

Following her visit to Qatar, TCG Gökçeada will sail to Pakistan and will take part in the exercise AMAN-19.

Pakistan started to organize AMAN multinational exercises in 2007 to promote regional cooperation and stability, greater interoperability and to display a united resolve against terrorism and crimes in the maritime domain including Piracy. AMAN-19 is the sixth such exercise planned.

After completion of the exercise, TCG Gökçeada will join CTF-151, the multinational task force against piracy off the coast of Somalia and will return home on 17th March 2019.
