ÜTĞM. ARİF EKMEKÇİ (A-575) is finally delivered to the navy. Ekmekçi and her sister Güngör was to be delivered in 2016, within 26 months of the project start which was in 2014. Turns out even navy is not above horrible procurement choices.

Deliberately awarded to Selah Shipyard (now acquired by Ada Shipyard) by SSB. Unfortunately at the time it was awarded Selah was neither financially or technically capable of completing the orders. That was made under a plan, to homogenize roles of shipyards in military related orders and create new candidates who may export these later. But one may also see politics were heavily involved in the process.

VLS above Helicopter compartment
Nice photoshop skills we can greatly make use of that :).

Adding on top VLS, making Corvette higher would cause stabilization problems?
It's in center of mass. But I do wonder how much weight could be placed on top of the helicopter compartment as there are all kind of things on I class which is similar to ada class.

I don’t think that it would present a huge engineering challenge to build a structure strong enough to hold a large, heavy mass on top of the hangar. Wouldn’t be easy but it can be done and extremely expensive and even might extend the overall construction time. Also the the size and weight added might make the ship top heavy and cause severe rolls on high seas.

The question, I believe, should be why would you want an entire VLS unit sitting on top of helicopter hangar, of all places.


EDIT: Turns out sitting a VLS unit on top of an already existing helicopter hangar, might present a huge engineering challenge due structural detailing and designing.
I stand corrected, and gladly too 🙂

I understand your worries but we need to increase the protection level of the Ada Class and that is the best way. Some kind of a RAM pointed upwards and covers around it.

From a visual calculation POV it is in the middle and in the same line as the funnel. It could be top heavy but we could play with materials it doesn't necessarily has to be metal as there are carbon fiber boats and they do stand corrosion.

Maybe it could be a composite ADA Class Modification.

You have not studied or currently not studying naval architecture (that's partly what i hope to hear too), right?

Apart from issues related to stability, that doesn't seem like a feasible solution to mount a full or short VLS on top of the hangar. The structure can be made to bear load of a VLS, but the position is too high to be adapted (unless the hangar itself is sacrificed for VLS). We may see Ukranian Ada Class approach and in a similar manner it is possible to fit up to 16 missiles on sides of the hangar - through not full VLS as in MILDAS but individual cold launched cells. If the cells are compact enough the space between the exhaust funnel and mast at the aft position can be utilized with a similar approach. I believe above the hangar should be spared for a CIWS or PDMS.

that is the best way.
According to whom? Too much self-confidence present out there. However, i personally encourage you to study and work an concepts, we even have a dedicated thread around here to post personal concepts and discuss it with people.
This is the thread to discuss personal concepts:

It actually may turn out to be an engineering challenge if we start to dive into structural detailing and designing. However, it is pretty easy to design it "conceptually".

I'm not an expert in anything defense really, but if history has shown us one thing (or even recent history in Ukraine) its that logistics win wars. How do we stand logistics wise in the Navy? Is the ratio of combat ships to support ships adequate?

Please enlighten me @Anmdt and resident naval experts.
I believe that currently we are in a good state (also as shown in the Libya campaign). But speaking for the future TN needs a second vessel in DIMDEG project (sistership of TCG Derya) and an extension to DIMDEG with autonomous systems. As well as ships smaller than DIMDEG build with lower costs (STM's FRT for example). and smaller ships for coastal refueling (2 are under construction but we may consider larger versions)

That sounds to me like the most sensible approach. Can we use Sungur as an interim solution? While it obviously doesn't have the range of Hisar, it still has an 8 km range, and it already has a launcher that we can probably integrate with the ships easily.

This is Levent point defence system. It has a Sungur missile and a bigger longer range Levent missile that Roketsan was developing.

Roketsan envisaging to use it from on board UAVs, as well as for naval purposes. Depending on the type of target and on the intercept range, the 8 km Sungur and the new Levent missile, which is still in the concept design phase, according to Roketsan officials , will be used. It will definitely be a bigger missile than the Sungur, will work at high supersonic speed, and will have a greater range and a wider envelop, however no more data were delivered due to the early state of development. According to released information Levent will feature manual, semi-automatic and fully automatic modes, and will be able to operate autonomously or in integration with the vessel’s sensor systems. The missile will leverage the R&D work carried out in seeker heads, RF sensors, proximity sensors, etc, and will include many subsystems developed in earlier air defence projects.
Unquote.

The larger Levent missile, although not disclosed, may well be based on a Bozdogan or even Gokdogan with a decent altitude and a longer range than any improved Sungur missile which has a range of 8km and an altitude of 4km. These two missiles and a Gokdeniz CIWS would give a fairly good layered air defence cover to the ship as far as point defence goes.

In stead of messing up the deck or hangar top of the Ada Class to include VLS missiles, augmenting the point defence system it has, may prove to be a better and more economical choice. It has also be remembered that the main Oto Melara gun is also capable of being used as an air defence weapon with a range of 16+km, after Aselsan developed fire control system is incorporated.

Datum AŞ multi-purpose midget submarine design, that will be the base configuration for 4 different designs (to start with); SOF Delivery (shown in image), Submarine Rescue (limited depth), Touristic submarine and modular submarine development test-bed, the project is now supported by SSB via TKY (Technological Contribution Responsibility) of the Sefine Shipyard - DIMDEG project.

The SOF variant will have a floating antenna.

Fits into a 20TEU container and transport aircraft.

Don't know if it counts since it is rather an R&D and technology gain project.

DATUM - ITU NOVA (SSB project)

  • Multi purpose midget submarine technology demonstrator (under construction)

Told y'all. It is under construction, In a few weeks the company is expected to hold an event to present the progress.

Primarily a test submarine, technology demonstator and base for future unmanned submarines as a working mini-sub platform. However, it requires decent amount of workmanship to transform into a military product, as is - it offers quite a good start. It is a great capability and know-how to be acquired by a start-up.

Double hull (FRP outer hull, steel inner hull), 2 foldable periscope configuration, 2 torpedoes (for tests), electric submarine, 4 crew (2 operator, 2 test team).

Awesome. So it will be built just As a test bed to test EW and other components for future mini sub projects. Is it correct?

Testing any underwater or submarine based components, and possibly anything would be related to unmanned submarines in far future.

According to photos, could you please elaborate specifications? Dimensions, weight, range, cost?

Fully electric without Diesel? And two heavy 533mm torpedos?

Length: 12 meters
width: 2,30 meters
diving depth: 300 meters
cruise speed: 4 knot
maximum speed: 8 knot
cruise time/endurance: 20 hours on 4kt
Crew: 4
main propulsion : Lead-acid battery

The maximum depth is really impressive. 300 meters.

Absolutely maximum depth is great.
İt might weight around 30-40 ton.

This is a TKY (Technological gain liability) project, likely a percentage of DIMDEG project is used for here. Shouldn't be more than few million dollars including the R&D.

It is transportable by a low-bed truck, so definitely not that much. The dimensions are overall, a portion of the dimension is floodable (between the two hulls). My bet would go for less than 20 or even 15 tons.

So noone could fuck around our critical naval bases, harbours etc.

Also TCG ANADOLU could be mother ship.

Kinda Bayraktar TB2 or YTKB.

We are looking forward to seeing its sonars and sensors. Personally i would love to see it with Synthetic aperture Sonar.
