Both India and Russia uses Kilo class, I think it's a perfect fit for your navy?
kilo is also in the list. vietnam bought 6 improved kilo without AIP for 2 billion USD. so we would choose Chinese varient with C708 Ashm as being 300m USD per unit is the same. :D

Thailand Subs Compare to other South East Asia nations subs
View attachment 394770

With AIP (Air Independent Propulsion) Technology and ASM (Anti Ship Missile).
S-26T Subs have upper hand compare to other SEA nations Subs.
Yes greatest news ever. I hope the Siamese buy more Chinese submarines.

I think China shall concentrate on building single hull structure subs.

Why did not Vietnam opt for the better equivalent from China?

Although I understand that our Russian partners also do need cash infusion in these difficult times, Vietnam would get much greater value for the money it has paid by choosing China's equivalent submarine.

Don't make our Viet boys feel good. No way selling weapons to them.

The Royal Thai Navy (RTN) on Monday signed a contract with a Chinese company to procure a S26T diesel-electric submarine, a move experts believe will promote China's export of conventional submarines.

The contract was signed in Beijing by RTN chief of staff, Vice Admiral Luechai Ruddit and Xu Ziqiu, chairman of the stated-owned China Shipbuilding Industry Corporation (CSIC). According to CSIC's official website, this is the company's second submarine export contract, after an eight-ship deal with Pakistan's navy in 2015.

"The submarines from China are the cheapest, with quality that is acceptable. [China] also offers services after purchase, something extra that we have received," Thailand's Prime Minister Prayut Chan-o-cha was quoted as saying by Nationmultimedia.com in March.

The S26T will be the RTN's first submarine since the end of World War II. Due to domestic politics and a budget shortage, the country delayed its plan to buy a submarine until China offered an unbeatable deal.

According to Nationmultimedia.com, the ship will be nearly 78 meters long and 9 meters wide. It will be equipped with the latest technology, including a AIP (Air Independent Propulsion) system, which will allow the ship to stay underwater for up to 21 days without resurfacing. Normal nuclear-based submarines can dive for around seven to 10 days at a time.

Russian is not Chinese best friend. Russian are just strategic partner. Russian say they are going to build super powa nuclear aircraft carrier four years ago and now not even a screw for it is made. You think you can trust Russian words?

You are just being selective in choosing argument to suit your agenda. If Russian Kilo is so good, why didnt China buy more instead of building its own Yuan submarine? As for your good friend Russian. They promise China to release all source code for your Kilo in even of war between China and vietnam. Russian say Vietnam is not even worth a penny and can be betrayed anytime. Reminbi looks more attractive. :enjoy:

Ohhh, the truth hurts! :cry::cry::cry:

Lol, Pathetic :D
Your kilo is the Outdated one, without AIP (Air Independent Propulsion) Technology.

Every latest Modern Subs today, have AIP Technology.
Quiet and Deadly :dirol: S-26T AIP Subs Thailand will bully your outdated kilo in the middle of ocean.

ADVANTAGES OF A.I.P


The use of AIP on a diesel-electric submarine, greatly increases their underwater endurance, allowing them to continuously stay submerged for weeks without surfacing. Although the submarine eventually needs to surface to charge its batteries and their endurance is nowhere on-par with nuclear powered submarines, the vast increase in endurance offered by AIP gives them an advantage over non AIP equipped diesel-electric submarines.

In April 2006, a German Navy submarine U-32, equipped with a Siemens proton exchange membrane (PEM) compressed hydrogen fuel cell AIP, made a 2800 km uninterrupted underwater journey without surfacing/snorkeling! This is in stark contrast to non-AIP equipped submarines which can cover only 500-800 km before they have to surface and recharge their batteries by running noisy diesel generators. Comparatively, a nuclear-powered submarine has unlimited underwater endurance!

Again in 2013, U-32 set a record by traveling underwater continuously for 18 days without surfacing! Comparatively, a non-AIP diesel sub has an underwater endurance of just 4-6 days before it has to surface. This shows that AIP-equipped diesel-electric submarines are far more capable than their non-AIP equipped counterparts when it comes to endurance.

AIP Usage Around The World
As of 2016, the following countries have developed their own AIP systems to be fitted on submarines.

You sound as if you don't trust your own Navy too much despite 10 times bigger but rely on treason of the Russians. What makes you believe Russia will sell Vietnam for a handful Yuan?

Aip is nice but not decisive. Aip sub can stay longer under water but is useless if easily being detected by enemy sub.
