TR Navy Naval Programs

[mohammadtd]

Past 10 years in my job, never seen one silent diesel engine. They run pretty noisy on submarines too. Yet we have got a lovely bulkhead (well - isolated) that keeps it away from operations center.

Despite of having maximimum speeds over 20 knots, lead-acid batteries generate toxic gases when heavily loaded and tends to warm up beyond how it can be cooled. I am sure it can run more than several hours at maximum speed (theoretically considering the battery capacity only) but the battery temperature and aforementioned gases wouldn't let it happen.

Been lucky to dive with a submarine before and after MLU, and lastly with one Reis during trials. And i came to this conclusion; the real mastery of diesel-electric submarines come with the PMM (Synchronous motor) and double-platform isolators. AIP, Li-Ion, Lead-acid introduces a little 'bump' there. AIP indeed gives a one-time shot skipping few snorkels and gives an upper hand but it is not enough alone.

While with Preveze and Gür Class Modernizations we are taking these submarines to what Reis Class have, in terms of electronics, sensors, integration of weapon - network systems, the difference of motors and double platform are absolute.

Possibly these two techs will be the bottleneck at Milden programme, i have no doubts on that AIP and Li-Ion can be achieved sooner than PMM double-isolating platforms.

Would you please shed light on Turkey's future API program? I don't see any improvement on that. Thank you in advance.

Perhaps, This piece by @Yasar_TR might give you a new insight on future of Turkish sub propulsion program(s)

Japanese Soryu class submarines were AIP submarines. However, they produced the last 2 submarines as Li-Ion class. And they are producing the last Taigei class with Li-Ion propulsion too.
Japanese submarine captains complained about the slow speeds of AIP submarines, emphasizing the importance of getting away from the area they are in quickly, after using torpedoes, and in an emergency, and as a result, the Japanese Navy turned to the Li-Ion system in its new submarine concept.

Inspired by the Japanese, we are also studying developing a Li-Ion propulsion system. Although AIP propulsion is planned for Milden, the complexity and external dependency of this system may push us towards Li-Ion powered submarines.

How about the one they fitted on to TCG Gaziantep?

MKE’s 76 mm Barrel Enters Inventory on TCG Gaziantep | TURDEF

The Turkish MoD announced on social media that the foreign-made 76 mm main naval gun barrel on TCG Gaziantep has been replaced with MKE’s indigenous barrel.

And the one one TCG Beykoz?

Gaziantep just had a barrel replacement. Beykoz had a test article, call it a prototype. And I believe she is now retired. I think they consider these 3 as "serial" production units. Quote is directly from MSB's weekly briefing, not Akbaba's own words.

Only the barrell replaced on the Gaziantep. I don't know what entails with the barrel replacement(I thought they just replaced the barrels but it might be more complicated than that) but considering the unique gun position on the Gabya's, I am not sure if full replacement of the gun is possible.

3rd MKE 76mm gun was delivered to Istanbul Shipyard Command to be installed onto İstif Class TCG İzmir. First two guns were installed on the first two Hisar Class OPVs.

Didnt aslo 1st istanbul have national MKE 76mm gun?
1 -first i-class
2-Hisar class
+ Izmir frigate total 4 ??

No. It uses the Italian OTO.

And why are we using a Persian name(Fersah)?

 

[uçuyorum]

And why are we using a Persian name(Fersah)?

At the end of the day, Turkish includes many words from Persian, Arabic and French, and Persian words are some of the nicer ones admittedly, more deeply embedded in our culture and literature. Some very basic root words also have common origin between Turkish and Persian ( aş , eş ) etc

 

[Turkic]

In modern Turkish, you can't talk a shit without using Persian-Arabic-French words.

 

[hugh]

It is a designation with a single word, not a conversation starter. It's not like we ran out of Turkish vocabulary and started picking loan words.

 

[Sanchez]

And why are we using a Persian name(Fersah)?

It's an old nautical term that's been in Turkish for close to a millennium. It's Turkish.

 

[Yasar_TR]

In modern Turkish, you can't talk a shit without using Persian-Arabic-French words.

That is not entirely true.
If you want to, you can. At least mostly Turkish. There are Turkish versions of almost each and every word. Fersah is a unit of distance covering some 5km.
In English it is “league” which is 3 miles. Fersah is the Arabic version of the Persian word meaning the same.

Actually it is but it's not related to the topic and would require long explanations.

You can talk using Turkish words only as you say but it would require a lot of effort.

Oh btw, I'm not saying there are more words from other cultures than ours in Turkish. It's just we use those foreign words more often than ours in our daily lives. So please consider my thoughts on the modern Turkish we use daily. Not all of it. Anyone to say Turkish has no Turkish words should be considered internet troll.

I have to add one more thing; as the populism is taking the youth day by day, they will be using more foreign words in the future and we will end up using a single language with different derivatives in the world. Just like how Europe includes some totally different races but it's too easy to catch words between their languages. It's a long process but www accelerated it. We are a part of the process and we're losing words everyday. They're starting to exist only in dictionaries.

Admins can freely delete this post because it is totally out of topic. Already we're not claiming different things at all. Turkish is Turkish and it's unarguable. Do we use foreign words often and would it be hard to talk without them ? yes.

Making meteksan out of busines in sonar systems

I think it is so far only meteksan working on fiber-optic based acoustic sensors, that comes light in weight and adaptable in size. While all of those which (Aselsan, Meteksan, Armelsan) relies on Tübitak's sonar crystal tech. So basically, those three companies are not developing the wet-end but dry end parts of the sonar.

CA96 seems to have same amount of hydrophones as Altas Elektronik's CSU CA that is present on Preveze and Gür Class.

I really hate Persian and other foreign words, it's really annoying that our language is invaded by so many foreign words even though we have a great language.
