Seawolves don't have the VLS but I believe could launch TLAMs from the torpedo tubes.

Seawolf has unique 660mm tubes afaik. That's why I mentioned Astute.

 

[OPTIMUS]

In my opinion, AIP technology with fuel cells is the wrong way for submarines, although it has been used in several countries. The future is lithium-ion operation.

1) Very long underwater operation,
2) very direct response to the command,
3) very high underwater speed,
4) very short charging time,
5) low maintenance,
6) Known and more controllable technology,
7) Ease of construction and
8) Placement in submarine bodies.


Fuel cell operation is exactly the opposite of these.

The Japanese have realized this and equipped their last three SORYU class submarines and new Taygay class submarines with Li-Ion technology.

 

[TheInsider]

Tomahawks can be launched from 533mm torpedo tubes. Tomahawks can also be launched from VLS.

 

[Chocopie]

Korean SLCMs are all launched through 533 mm torpedo tubes.
From KSS-II (Korean Type 214 version) and heavier KSS-III as well (VLS reserved for SLBMs).

Hyunmoo 3C long-range CM (2012)
533 mm diameter submarine (600 mm ship/land launched)
6.2 m length
1,360 kg launch mass
max. 1.2 mach speed
1,500 km range
450 kg warhead
< 2 m CEP

Test video at 0:20 min. you can see the air-pressure launched orange capsule piercing the sea surface, opening of top cap and igniting turbojet engine from a KSS-II Son Won-Il class sub.

Koreans also chose li-ion(KSS-III Batch II). We should go that way. We can use Lithium Iron Phosphate batteries (200Wh/kg) that are safe for underwater use. If we want to be super extra safe we can go for Lithium Titanate (180Wh/kg). Medical tools have Lithium Titanate batteries because they satisfy the safety requirements of medical tools. We should replace all lead-acid batteries immediately. It is not a difficult process to replace existing batteries.

Koreans have chosen diesel engine + fuel cell AIP + Li-Ion for now (KSS-III Batch II).

They don‘t believe in Li-Ion solely like the Japanese who deployed outdated Stirling AIP instead of fuel cell AIP for their first batch of Soryu class subs.

For later Soryu and Taigei class subs they didn‘t want to invest heavily in fuel cell AIP technology …

IMHO, AIP is unnecessary for mid-sized submarines like the Reis class. It is not worth the cost or the risks involved. Li-Ion batteries will provide enough underwater endurance. For heavier subs with VLS capability, the AIP system might be a good addition.

The first SORYU class boat with Stirling engine (SS 501-Soryu) cost $510 million.
11. SORYU class boat with Li-ion propulsion (SS 511- Oryu) cost $601.3 million.

 

[OPTIMUS]

but what is funny about the matter; the Turkish Navy will know immediately when a Greek AIP submarine is on its way to Germany for refueling. And his absence in the Mediterranean will last a very long time.

 

[Chocopie]

Submarine builders like Germany‘s TKMS (Type 212 CD/214/218 SG) believe in fuel cell AIP coupled with Li-Ion batteries as future propulsion. Therefore also Norway, Italy, Singapore as customers.

Koreans (Hanwha Ocean, HHI) with their German sub tech roots and indigenious PEM fuel cell technology do as well couple AIP + Li-Ion.

Spanish Navantia will deploy bioethanol AIP on their S-80 subs.

French Naval Group (problem-ridden MESMA AIP) and Japanese MHI & KHI (outdated Stirling AIP) are betting on Li-Ion out of sheer necessity in my opinion.

PS: Chinese Type 39A diesel-electric subs use AIP as well. Not much is known about integration of Li-Ion packs but their commercial batteries tend to go up in flames easily

 

[mohammadtd]

NO!!

After TKMN paid a punishment of 100 million Euros to Turkey, the Germans insisted that the Turkish submarines must be refueled in Germany. But they didn't get through.

The Turkish submarines can get maintenance in Turkey but Greek submarines have to go to Germany.

AIP is a very valuable commodity in the submarine. You have to use this technology very sparingly. That's why AIP is primarily intended for creeping speed. Charging takes a very, very long time. Each additional knot reduces the underwater duration of the oversized. It also depends on the discipline of the crew. The Japanese have done 30 days underwater with their first SORYU's. For the Germans 16 days, for Italians 13 days, for the Greeks 11 days. The Japanese may have broken the record with their new SORYU's. Quite possibly. I am curious how long you Turkish submariners could stay under water.

How difficult to develop AIP technology for Milden?

 

[Anmdt]

Seawolves don't have the VLS but I believe could launch TLAMs from the torpedo tubes.

Now i am trying to figure out if there are two sub launched tomahawks. I recall one that is installed via a capsule allowing vertical swim out, does another one have a capsule container as well? This would be challenging if so, maybe a separate capsule to allow swim-out? Appearantly i found out early versions are torpedo tube launched as well.

 

[TheInsider]

Sub-Atmaca training capsule prototype.

Roketsan smart capsule concept

The smart capsule will have its own propulsion, battery, mission computer, INS, and cruise system. The capsule will carry the missile to a predetermined launch spot the missile will be launched from that spot.

Advantages
-Protection of submarine stealth (it can be launched from deep underwater like a torpedo and can travel a considerable distance away from the submarine)
-Optimal use of operation area
-Sudden attack capability and limited reaction time
-Underwater/surface orbit/concept optimization

Tomahawk TLAM Block IV launch from HMS Astute

It looks like a test is on the horizon because the capsule looks pretty serious, I think we will have like six ATMACA variants in total.

 

[Huelague]

Yes, which Gezgin SLCM? The one that will launch from Reis and Gür, or the one that will launch from Milden?

Attention! Spoiler alert .
Gezgin SLCM, launch from Reis.

Just curiosity, at future, can we see 4 çakır in one encapsulated container. If çakır dimension reduced slightly, 4 can be packed. For example 2 çakır lir , 2 çakır as. Or 4 çakır sw.

AND concerning the capsule of SUB ATMACA and GEZGİN

 

[Strong AI]

 

[Kaan Azman]

Gezgin cant use the same capsule with Sub Atmaca as there is a huuuge difference in size. But we can say for sure tjat the capsule from ceremony is for Sub Atmaca and probably Hisar Derin

A general summary of the Navy and presidential statements at yesterday's ceremony:

1- National Destroyer: (President Erdoğan) The construction activities of the TF-2000 Air Defense Warfare Destroyer will soon begin at the Istanbul Naval Shipyard Command.

2- The systems mentioned as the aircraft that will serve on the National Aircraft Carrier:

• Hürjet Naval Attack jet,
• Kızılelma and ANKA attack jets,
• Baykar Tactical block-3
• and national helicopters.

While listing these systems, the President described the purpose of the AC as the protection of rights and interests in overseas spheres of influence.

3- New Shipyards: (Naval Forces Commander Admiral Ercüment Tatlıoğlu) Within the scope of increasing the current opportunities and capabilities of the Aksaz Shipyard Command, a dry-dock that can also dock the TCG ANADOLU and the aircraft carrier we will add to the inventory is planned to be put into service in the near future. Our next goal will be the establishment and opening of our Mersin Shipyard, which has critical importance in the Eastern Mediterranean theater of operations.

4- MILDEN National Submarine Project (Admiral Ercüment Tatlıoğlu) The construction of the first of our national submarines will begin in 2025. Our ultimate goal is to equip our national submarine with national systems and devices and use it entirely with national weapons. We will be one of the six countries in the world that can design and build its own submarines.

New Submarine Floating Dock: (Admiral Ercüment Tatlıoğlu) In this context, the 3000-ton indoor submarine pool, where construction, maintenance, repair and modernization activities of submarines can be carried out day and night under all types of climate conditions, was also put into service today. The closed submarine dock is a critical and strategically important part of the national submarine production target and will contribute to the development of national technology.

(With the ceremony held in Aksaz: TCG PİRİREİS Submarine was added to the inventory. TCG MURATREİS Submarine started its sea tests. TCG HIZIRREİS Submarine met with the water. Submarine Floating Dock put into service. Fuel oil vessels added to the inventory)
