In the Il-112, unlike in the other large aircraft projects, they also didn't do any wind tunnel testing and relied on performance numbers from computer simulations. From what I know TsAGI was not involved in the project at all. This is highly unusual to begin with.

I double checked this and it turns out I was wrong. It was wind tunnel tested.



But still there were claims that the wing area might be insufficient. The cause of the crash was clearly the engines. The only doubt is if the wing design was also a problem or not.

This is supposed to be the first modified Lada class submarine. It is a vast improvement over the Kilo. It is much more quiet, has better sensors, is smaller, can pack the same weapons load, with a much smaller crew size thanks to better automation (35 crew vs 52 in older boats). But it is still obsolete compared with leading edge diesel submarines like the ones from MHI or HDW. In that it neither has lithium-ion batteries nor does it have AIP.

The second submarine in the class is also expected to enter service this year.

The Lada had a long and tortuous development process and took like two decades to enter service. Let's see if they finally got it right and will order it in a larger series.

Kronshtadt submarine joins Russian Navy​

The ceremony was also attended by Deputy Industry and Trade Minister Viktor Yevtukhov, Northern fleet Commander Alexander Moiseyev, and representatives of the United Shipbuilding Corporation and the shipyard

MOSCOW, January 31. /TASS/. The Kronshtadt diesel-electric submarine of Lada-class project 677 has joined the Russian Navy. The flag-hoisting ceremony was held at the Admiralty Shipyard in St. Petersburg, TASS correspondent reported.
The Defense Ministry said the submarine joined the Kola flotilla of the Northern fleet.
"It is a gala day for the Navy, as we accept a new-generation submarine based on new physical principles and armed with powerful weapons. The submarine will operate in a brigade of the Northern fleet," Navy Commander-in-Chief Admiral Nikolay Yevmenov said at the ceremony adding the sub confirmed its reliability, maneuverability and stealth features at trials.
The ceremony was also attended by Deputy Industry and Trade Minister Viktor Yevtukhov, Northern fleet Commander Alexander Moiseyev, and representatives of the United Shipbuilding Corporation and the shipyard.

Submarines of project 677 are fourth-generation non-nuclear boats. They are designated for independent operations against surface warships and submarines in the assigned area, cruise missile strikes at ground targets and anti-submarine defense of coastal areas. The surface displacement is 1,750 tons, the length is 68 meters. Full underwater speed is 21 knots, the range in surface trim is 6,000 miles at a speed of 7 knots. The submarines are armed with Kalibr missiles and six 533mm torpedoes. The crew is 35 men.

Batteries or AIP does not make it advance. it gives extra capability.
Not every Scorpene Subs have AIP and French are now offering Lithium in Subs. This Lada subs seem small.

It's kinda because no committed export client found yet. The Russian navy itself seems content with 636's or basic Lada. As they have nuclear boats.

The remarkable feature of Lada tho is their new "Lyra" sonar.. much more advanced and bigger aperture than 636's MGK-400.

The new RPL-20 light machine gun developed for the Russian army is ready for state testing. The machine gun was already presented earlier, but it was modified to meet the customer’s requirements. The RPL-20 machine gun was created taking into account military feedback collected during testing of the RPK-16 machine gun, which was considered as a replacement for the Soviet RPK-74 machine gun. The RPL-20 belt-fed light machine gun has an open rotary bolt and a long-stroke gas piston. Equipping a machine gun with belt feed reduces the soldier's mobility, but increases the machine gun's rate of fire. The RPL-20 machine gun has interchangeable barrels of different lengths, which allows you to change them depending on the tasks being solved, as well as in case of overheating. Currently the machine gun is available in 5.45×39 mm caliber; in the future it will be exported in 5.56 and 7.62 mm calibers that meet NATO standards. The machine gun has a folding stock with an adjustable cheekpiece. The weight of the machine gun with a short barrel is 5.2 kg, with a long barrel - 5.5 kg. The machine gun is equipped with a Picatinny rail for mounting sights and other accessories. The range of hitting targets with a machine gun is up to 500 meters, the rate of fire is 700 rounds per minute. Cartridge box capacity: 100 rounds.

In the fall of 2022, Rubin’s deputy general director for foreign economic activity and military-technical cooperation, Andrei Baranov, told RIA Novosti that the Central Design Bureau intends to create a VNEU based on fuel cells to produce hydrogen from diesel fuel.

“We are creating VNEU based on fuel cells to produce hydrogen from diesel fuel. We get water from oxygen and hydrogen, and electricity is released. The most difficult question: where to get hydrogen from? Carrying it with you is cumbersome, loading it is difficult and dangerous. Therefore, we propose to obtain it from diesel fuel - this scheme is called reforming,” Baranov said.

According to him, this approach is promising in terms of secrecy, ease of deployment, and other important parameters for the Russian fleet.

Vasily Dandykin believes that the creation and implementation of VNEU in Russia in the coming years is a very real prospect.

“The air-independent engine will allow the submarine to remain under water without the need to recharge the batteries for approximately three weeks. We can expect that in the future the fleet will receive such systems, thanks to which our submarines will become more autonomous,” the expert concluded.

Yes but current Lada have no AIP.. Nor Russia ever complete their D-27 Kristall Hydrogen-Oxygen PEFMC AIP module.

yet but they want go in this direction. they also doing alot of research on batteries now. so highly likely things will change with time.

This video of Tu-204 (not Tu-214) refurbished for Civil Aviation at Aviastar. It shows that Russia has retained skills of different plants doing multi tasks. back in Soviet days. it was considered largest aviation plant by land area.

Rosatom is being funded to work on technologies to implement a hydrogen infrastructure by the Russian government as part of a research project.



Rosatom recently announced the development of carbon composite overwrapped hydrogen fuel tanks.



Rosatom is already one of the world's largest producers of carbon fiber thanks to their UMATEX subsidiary. Russia also produces hydrogen fuel cells for Russian buses.

Rosatom's mining subsidiary has also been trying to setup lithium mines in Russia to eliminate the need for imports.

So I would say they have the technology. The thing is the military originally wanted to use a reformer that would extract hydrogen from diesel. This is way more complicated that what the Germans are doing with their AIP subs. Only the Spanish have a similar submarine project. Except the Spanish want to use an ethanol reformer. But the lead S-80 Plus submarine does not feature the AIP system.
