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.

TCG Edincik Gets A New Mine Hunting Sonar

The legacy DUBM 20B sonar system on board of TCG Edincik, here off Istanbul in 2017, was replaced by indigenously developed MATESS system.

It was revealed during the industry day of the Nusret 2018 mine warfare exercise, that the Turkish minehunter TCG Edincik was fitted with the mine detection sonar of Aselsan.

Aselsan started to development of MATESS, mine detection sonar as a private project without a firm order from Turkish Navy. When the system was evolved to certain maturity, it was installed on board of Edincik class minehunter TCG Edincik.

The minehunter started her life as FS Calliope in 1971 in French Navy. In 1999 she and her 4 sisters were bought by the Turkish Navy. She was renamed as TCG Edincik and transferred in 1998. In her original configuration, she was fitted with DUBM 20B minehunting sonar.

According to Aselsan MATESS is a mine detection and object avoidance sonar, providing automatic detection, localization and classification capability for underwater objects, supporting ships navigation safety at high reliability.

The system is made up from the transducer array, transmitter and receiver, signal processing and user interface units.

Aselsan expects the testing of the sonar system on TCG Edincik will end in late December and in early 2019 the system will officially be inaugurated to Turkish Navy. Her attendance to the Nusret mine warfare exercise should be regarded as a part of the testing and evaluation process of the MATESS by Turkish Navy.

Turkish Navy Has Started To Hunt Mines With Autonomous Unmanned Vehicles


Turkish Navy has entered the age of autonomous unmanned vehicles (AUV). This transition happened without much fanfare or publicity.

The above photo was published on Turkish General Staff website and shows the deck of the Aydın class minehunter TCG Anamur during the ITALIAN MINEX-18 held in Italy between 21 and 29 May.

The orange and yellow gadgets on the back of the deck are practice mines used during the exercise. The large yellow device partially visible on the left is a French-made PAP-104 underwater unmanned vehicle used for exploration, identification and sometimes for the destruction of mines. That system is remotely controlled and is not fully autonomous. This is the standard ROV of all Turkish minehunters.

The yellow torpedo-like object, in the middle, is of much interest. It is a Gavia autonomous underwater vehicle made by Teledyne Gavia.

According to the information provided by the company, GAVIA (AUV) is a self-contained, low logistics, modular survey platform capable of delivering high-quality data while operating from vessels of opportunity or from the shore.

The system is field proven for applications that include MCM, SAR, and ASW training. The field-changeable and easily transportable modules make it well suited for rapid response to emerging requirements.

At least two 1000m rated systems were delivered in 2016. One is named Uluç Bora and the other Barbaros Dora. In one press release, the company states the end user as Turkish Air Force and the AUV’s will provide TAF with highly effective deep water, rapid response capability. I sincerely believe that the there is a mistake. Usually, all underwater operations are the responsibility of Turkish Navy. And currently, these AUV’s are operated by the Turkish Navy Mine Countermeasures (MCM) command in Erdek.

The most striking specialty of this UAV is its modularity. The vehicle can be configured even on the field by adding modules or taking them out according to the mission requirements. The length and the weight of the AUV’s vary according to the modules it has.

Though it is not confirmed I believe each Turkish GAVIA has in addition to the nose, battery and propulsion modules one DVL-aided INS module, one side scan/bathymetry sonar module, one multibeam profiling module.

Among other naval operators of GAVIA AUV are Poland and Russia.

Turkish Navy Conducted Live Test With Korkut Air Defence System

TCG Sokullu Mehmet Paşa returns from live fire test of Korkut D.

The unmanned gun turret and the 3D radar mount occupy the place, where once the 100mm gun turret was.

Turkish Navy and Aselsan have conducted live firing tests of the Korkut D gun system on board of TCG Sokullu Mehmet Paşa. The trials are believed to be performed during the first week of May.
Korkut is a Self Propelled Air Defense Gun System developed by Aselsan.

The initial customer for this system is the Turkish Land Forces. A typical system has one command vehicle and 3 gun vehicles. The command vehicles carry a 3D target acquisition and tracking radar, IFF system, and necessary to command and control systems. The gun vehicles carry an unmanned turret with 2 x 35mm guns, a fire control radar and electro/optical sensors.

The navalized system has a stabilized, unmanned gun turret and a mount for 3D target acquisition and tracking radar.

The Korkut D system made headlines in December 2016 when a Turkish boat carrying it for initial tests, run ashore on the Greek islands Kos island due to bad weather.

This time the test platform was provided by Turkish Navy. TCG Sokullu Mehmet Paşa is a very versatile ship. She was built for Germany Navy by Schlichting-Werft in Travemünde as a tender for fast attack boats. In Turkish service, she is used as a flagship of small ship formations, training ship for cadets and in a war as an auxiliary minelayer.

Prior to the tests, the original 100mm gun mount in X position on her board was removed, freeing space for the Korkut D gun turret and radar mount.

The position of the turret on board of TCG Sokullu Mehmet Paşa provides extra elevation angle to engage low flying targets and possibly to engage close small surface targets. The gun turret seems to be not penetrating the deck. This suggests that this is not a permanent installation and the original 100mm gun may return to claim its place on the ship.

TCG Sancaktar Handed Over To Turkish Navy

On 7th April 2018, TCG Sancaktar was handed over to Turkish Navy. She is the second ship of Bayraktar class landing ships, TCG Bayraktar being the first off the class.

The contract for the construction of new LST’s was signed in 2011. The value of the contract was 370 million Euros. The first ship was delivered in February 2017.

The ships can carry 350 persons, 20 MBT and between 24 – 60 vehicles. The closed parking area is 1100 square meters and the open deck parking area is 690 square meters.

It was rumored that TCG Sancaktar might be sold to another country but this sale apparently did not materialize.

Both ships have a good command and control facilities and management software. All lessons learned from operating and commanding amphibious forces from these ships will be used in the development of the software and systems to be used on TCG Anadolu.

I wish TCG Sancaktar fair winds and following seas

 

TCG Burgazada Started Her Sea Trials

TCG Burgazada sets sail for her first cruise. Photo: SSM

Undersecretariat for Defence Industries (SSM) published photos from the first test cruise of TCG Burgazada on 20 March.
The photos show an unfinished ship sailing on the Marmara Sea. Though SSM did not disclose the exact date when the photos were taken it is assumed that they were taken on 19 March 2018.

The cruise conducted as part of the factory acceptance tests. The ship was launched on 18 June 2016 and is expected to be commissioned in September 2018


This photo also taken during the test cruise shows three interesting things:

  1. New Aselsan made HIZIR torpedo countermeasure system launcher is installed instead of Ultra SeaSentor system used in the first pair.
  2. The antennas of the Aselsan built ARES-2N ESM system is not mounted
  3. The back looking AselFLIR-300D has not been installed yet.

There is clearly a lot of work to do to finish the ship on time. I think the test on Monday was done to check the performance of the propulsion system, whether the engines were functioning properly, how did they react to the controls, whether the acceleration and deacceleration of the ship were within the limits.

I wish TCG Burgazada fair winds and following seas.

The First Block Of TCG Anadolu Is Laid

The first keel block of TCG Anadolu was laid on 7th February 2018, nine 21 months after the construction has started.

The contract for the construction of the ship was signed in May 2015 after a four year long tender process.

The delivery of the ship is scheduled for the year 2021.

TCG Anadolu is based on Navatia’s Juan Carlos 1 design. She will be very similar to SPS Juan Carlos 1 in Spanish Navy and HMAS Adelaide and HMAS Canberra in Royal Australian Navy.

However, unlike her nears sisters in Spanish and Australian navies, the Turkish ship will only have diesel engines. There will be five MAN 16V32/40 engines each creating 7.680kW and propelling the ship up to 21 knots. The range is estimated to be 9.000 nautical miles.

National Electronic Warfare Suite

A comparison between the new EW configuration on board TCG Fatih (left) and the old one.

The new electronic warfare suite on board of TCG Fatih has been accepted after rigorous testing according to Aselsan.

The system is made of the following units:

  • Electronic Support Measures
  • Decoy Launching System
  • Dedicated or Shared Multi-Function Consoles

The heart of the system is the CPU of the EW processing and its interface with the operator. Aselsan has developed and installed similar systems to Ada class corvettes and Bayraktar class landing ships. So they have a good knowledge of development and implementation of EW systems. The most important physical obstacle was the mast on with the ESM antennas were installed. On Ada and Bayraktar class ships, these antennas are integrated into the closed mast. There was no place or top weight problems. On TCG Fatih, however, the antennas had to be put on top of the thin part at the end of the main mast of the ship. Therefore Aselsan used the antenna solution they have developed for Ay class submarines. Since it was compact enough to fit on a pole on a submarine, so it was also good enough to be mounted on the mast.

According to Aselsan, tests have been conducted both for ECM / EW suit and for the decoy launching system before the system was accepted by Turkish Navy.

It is not clear at the moment if this EW suite will be back fitted to the other Yavuz class frigates or if this EW system is part of the mid-life modernization program of Barbaros class frigates.

 

TCG Akın Decommissioned

Here is a photo from 2015 showing TCG Akın sailing through Bosphorus.

Today the long career of TCG Akın in naval service has finished. The ship can have a well-earned rest after 75 years.

TCG Akın began her life as USS Greenlet, a Chanticleer-class submarine rescue ship in the United States Navy. She was launched in 1942 and served in US Navy during World War 2, Korean War and Vietnam War. She was even in Tokyo Bay when Japan surrendered in 1945.

On 12 June 1970, she was decommissioned from US Navy service and immediately commissioned in Turkish Navy at Pearl Harbor Naval Submarine Base. Her transfer to Turkey took 40 days.

She was the sole dedicated submarine rescue ship untill the commissioning of TCG Alemdar in 2017.

I wish this old and elegant lady to be restored as a museum but most like she will either sunk during an exercise or scrapped.

Anyway, thank you for the service.
