"...The T625 is being developed as part of the Original Helicopter Program, coordinated by the SSB. The T625 prototype earlier used a pair of LHTECs, CTS800 4-AT turboshaft engines that have 1,373 shaft horsepower each, created jointly by Rolls-Royce and Honeywell.
The TS1400 is also expected to be used on Hürkuş training aircraft and T129 Tactical Reconnaissance and Attack Helicopter (ATAK), as well as its derivatives developed by TAI."

TEI continues its efforts to complete the engine for GÖKBEY first general-purpose helicopter to be produced. Akşit stated that they had developed a powerful engine and said that the TS-1400 engine produced 100-150 more horsepower than the engine (LHTEC-CTS800-400A, 2 1014 kW) used in GÖKBEY’s tests and currently powering our T129 ATAK attack helicopters.
TS1400 engine, which prefers a two-stage centrifugal compressor like the LHTEC CTS800-4AT engine with a high-level weight and volume optimization, requires axial (front) air intake assembly changes that are necessary for a turbofan engine design. Although extremely suitable for turboprop (TP) or turboshaft (TS) engines, the two-stage centrifugal compressor architecture has some disadvantages in terms of the cross-sectional area due to both the bypass ratio (the ratio of the air that goes through the core, i.e. the capacity) as well as the placement of the radial air assembly and the combustion chamber.
The TS1400 is anticipated to be developed further with a multi-stage axial flow compressor and then a single-stage centrifugal compressor assembly to be able to evolve into a high-performance, low-thrust turbofan (TF) engine.
Announced by TUSAS General Manager Dr. Temel KOTİL during the IDEF ‘19 Fair for the first time, the indigenous 2,500-3,000 shp turboshaft engine, which will power the T129 Mk-II (ATAK-II) Heavy Attack Helicopters, can be expected in a similar configuration. "

Yes, more powerful. About 100-150 HP. TS1400 for Atak? Maybe.

fantastic, once integrated onto T129 then it will be in Pakistani hands and the yanks can shove their engine up theirs."...The T625 is being developed as part of the Original Helicopter Program, coordinated by the SSB.

Now the US would come running with their engines! Insha'Allah by that time the Ehl-i Sheytain (beggars = House Negros) that are possessing tne Pak folks now would be burning in fire like that from the 7th Jehennem.....

The turboprop engine for Akıncı must be derived from the core of the TS1400 turboshaft engine. Do they work for it? I think not at this stage. They don't strive for that kind of transformation. There are higher priority projects. There are projects of TS3000 turboshaft engine for our future heavy class helicopters and turbofan engine for our fighters. (MMU+Hürjet+MİUS)

For TEI, the hard part was the TS-1400. Design, test and classification from scratch, verification of state of the art manufacturing technologies and civil aviation safety certification process...
The process will be much faster for derivative engine types and even new high thrust turbofan engine groups. Already the general manager of TEI, Prof. Akşit states that with the confidence this gives, they aspire to much more higher targets.
The TS-1400 was one of the most critical steps not only in terms of TEI's company profile, but also in the localization movement of the Turkish defense industry in a broader sense. The accumulation and leap created by this project will be seen more clearly in the coming years.

The multi-purpose naval helicopter is indeed an increasingly urgent need for the Navy.more pictures needed...
I hope all that project goes paralell together, like we turn this to naval. Use it as UH60MR version.
I think the first expectation in our defense circles was about a variant of T-70 with subsequent orders. All major critical structures and avionics; including rotor gearbox and even engine combustion chamber localized and it is a platform where the TSK has many years of operational experience. Although the T-70 program continues on its way by receiving international awards, I guess it will not be possible to see a navy variant of this project anymore.
Although there may be risks of delay, a more correct step was probably taken and the +10 tons MTOW naval helicopter project suitable for maritime ISR and surface operations was launched over the T-625 infrastructure. When this helicopter enters service, it will become the navy's workhorse.
However, it is impossible not to agree with your idea of producing a naval helicopter in the same class over the T625. The aged AB-412/212s in the hands of the coast guard and navy can be replaced by a T-625 variant that will have flexible mission capability, such as the AW159 Wildcat.
