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.

 

 

ÇAFRAD Successfully Completes First Live Fire Test

The test bed for the ÇAFRAD prototype, TCG Göksu sailing through Bosphorus.

The large structure on the flight deck houses the illumination radar, multifunctional radar, and the IFF interrogator. The arrays of the radars are looking to the starboard side of the ship. Power generators and HVAC systems are also mounted on the flight deck.

 

On 13th December 2018, it was announced that a RIM-162 ESSM missile fired from the frigate TCG Göksu hit a target drone. The live shooting exercise was important as the target was tracked and illuminated by Turkish made radar system.

In November 2018 Turkish Navy started to field testing an Active Electronically Scanned Array (AESA) radar prototype manufactured by Aselsan. The prototype was installed on the flight deck of the Gabya –O.H. Perry-class frigate TCG Göksu.

The technology demonstrator prototype installed on board of TCG Göksu has only one set of multifunctional phased array radar and illumination radar. The arrays of the radars are looking to the starboard side of the ship. Power generators and HVAC systems are also mounted on the flight deck.

The ASEA radar project named ÇAFRAD (Turkish abbreviation of Multi-Functional Phased Array Radar) was first made public in 2012. The contract for the Phase I, was signed in August 2013 between Aselsan and –the then- Undersecretriat of Defence Industries. The contract value is 200 Million Turkish Liras.

Phase I covers the design, development, manufacture, and testing of the ÇAFRAD prototype, to be composed of an X-band multifunctional phased array radar, an X-Band illumination radar and an IFF system with nonrotating AESA antenna.

Phase II covers the design and development of a long-range active phased array radar and the development of multi-face antenna versions of multifunctional radar and illumination radar.

The multifunction active phased array radar will have a range of around 150km and it will be used for, horizon searches, air, and surface target detection, tracking and classification, small, low altitude and high-velocity air target detection and tracking.

The long-range active phased array radar will be used for, long range volume searches, air and surface target detection and tracking. When finished it will have a range of 450km.

The active phased array illuminator will be used for semi-active missile guidance.

The factory acceptance tests for the prototype were scheduled for 2017 and the testing on board of a warship was planned for the first half of 2018. Now with the FATs finished field testing has stated. When the tests on board TCG Göksu are completed SSB will start the Phase II. The deliveries of complete systems are planned for 2023.

When finished, the ÇAFRAD system is intended to be installed as the main sensor and fire control system on board of the TF-2000 air defense warships.

Turkish Anti-Ship Missiles Contract Signed

A test firing of Atmaca missile. Date unknown.

On 2nd November 2018, The Presidency of Defence Industries –former Undersecreteriat of Defence Industries- the main defense acquisition agency of Turkey announced that a contract for the serial production of Atmaca (Hawk) anti-ship missile was signed.

The contract was signed between PDI and Roketsan the leading company in the country for designing, developing and manufacturing rockets and missiles, as the main contractor. Aselsan the main defense electronics company is acting as sub-contractor and providing the RF seeker head and guidance section.

Since its start, the Atmaca Project has always been shrouded by thick layers of secrecy. And this habit continues still. Neither the value of the contract nor the number of missiles to be procured was revealed. The scheduled commissioning date of the missiles was also not made public. The press release about however mentioned that the first missiles are to be installed on board of the TCG İstanbul. TCG İstanbul is a İ class frigate currently under construction in Istanbul Naval Shipyard.

Turkish Navy EOD Team Destroys An Old Mine

The deadly catch. Photo: Balıkesir Haber Ajansı

This week a fishing boat operating off the coast of Ayvalık, Balıkesir found a mine in its net.

They have informed the Coast Guard and the harbor master. The old and probably inert mine was brought to the shore on board. A Turkish Navy EOD team was called by the Coast Gaurd. The EOD team brought the mine to an inhabited area and destroyed it by detonation.

The mine is believed to be from 1. World War era. Every year fishermen return with such deadly catch and provide the EOD teams always an opportunity for action.
