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.
