That is lame. I kind of hoped they would have used the M70FRU2 gas turbine but with that lackluster performance I knew it was probably not the case.

The M-507 is used in the Karakurt corvettes and the Alexandrit minesweepers.

They used the M-507s because the hulls in the original configuration were designed for that type of engine (all diesel CODAD) and not like the previous versions of the 12411 Molniya/ Tarantul-class project which had a propulsion system combined with gas turbines and diesel CODOG, or full gas COGAG.
However the Zvezda M-507 is the union of two M-504 radial diesel engines joined together on a gearbox.
They are very complicated engines due to the very high number of cylinders and pistons and related moving parts, this entails/resulted in shorter times to subject them to overhaul unlike classic diesel engines.
As plus points, they are very compact engines in size and develop high power, the M-507 - 10,000 hp, and the project 12418 should have maintained 3 axles and related propellers, therefore 3 Zvezda M-507 for a total of 30,000 hp

Russia is increasing the production of gunpowder, solid rocket fuel and explosives, Deputy Chairman of the Russian Security Council Dmitry Medvedev reported. In order for gunpowder production in Russia to operate at the limit of its capabilities, new plants are being created and old ones are being re-equipped. Now the plants regularly produce pyroxylin gunpowder for all types of weapons, artillery systems of all calibers, but there are problems with the supply of raw materials. The fact is that gunpowder production requires nitrocellulose produced from cotton, its production is concentrated in China and Uzbekistan. Since 2022, Russia has begun to actively buy nitrocellulose on world markets, but this was not enough, and China has also limited the supply of nitrocellulose to world markets. Since 2015, Russia has begun to decide to develop a new technology for the production of gunpowder from flax. As it turned out, new gunpowder from wood and flax cellulose is no worse than the usual one. The advantages of flax powder are higher energy than cotton, stability of characteristics, this allows to reduce the weight of the powder used to 8% and get the same values as when using nitrocellulose powder. The price of flax powder is up to 5 times lower, artillery shoots more accurately with shells with flax powder. Since the spread when shooting with the use of standard powders is 3-5 meters, and for flax powder this spread is 0.5 meters. It is worth noting that Russia grows flax in record quantities. In the future, the share of wood and flax cellulose in the production of gunpowder will reach 60-70%.

RT Arabic put Su-35 shooting down of MIG-29 at 213km at Science and Technology section. Su-30SM also capable of using it upto 300km.


however from Su-57 this R37M is capable of hitting supersonic targets at distance greater than 350km. I have said it before this Su-57 is closer to MIG-31 in performance than Su-35.

The main advantage of the Su-57 fighter is the use of the latest Russian long-range missile, the R-37M hypersonic air-to-air missile, which has a speed of up to Mach 6 (about 7,500 km/h) and is capable of destroying air targets flying at supersonic speeds of up to 2,500 km/h at a distance of more than 350 km, as well as the R-77M missiles, which are currently being produced in batches

Su-57 does not use R-37M.. it use Izdeliye-810. Completely different missile.

look identical size except for internal carriage. and they refer it R-37M for its use.

Among the main advantages of the Russian fighter is the ability to use the R-37M missile, which has already demonstrated high efficiency during the air defense. Thanks to these missiles, the Su-57 is capable of hitting air targets at a distance twice as great as its counterparts from the US or China.

The video shows the operation of the Russian naval air defense missile system "Osa-M", accepted into service in 1973, upgraded to the Osa-MA version in 1975 and upgraded again in the first half of the 1980s to the Osa-MA-2 version. The Osa-M air defense missile system is used on ships with a displacement of 500 tons or more. The Osa-M air defense missile system has two guides for 9M33 missiles weighing 128 kg, later upgraded to the 9M33M3 version. Under the deck of the ship, in a special "cellar", there are 4 drums with ammunition for five missiles each. After the launch of a 9M33 missile, it is captured by a missile sighting station, which guides it to the target. When the missile approaches the target, a command is given to arm the radio fuse, radio magnetic pulses are emitted and at a distance of up to 15 meters from the target, the warhead of the missile is detonated. The probability of hitting targets for the latest versions of the SAM is 70-80%, the probability of hitting modern targets is lower. The reload time of the SAM is from 16 to 21 seconds, the rate of fire is 2 rounds per minute for air targets and 2.8 for surface targets. The Osa-MA-2 SAM can hit targets at a range of up to 15 km and an altitude of up to 4 km, the minimum altitude of hitting targets is 5 meters.

Long-range M-46 guns were noticed in the Russian army. Soviet 130-mm M-46 cannons, one of the eyewitnesses noted, on one of the railway trains in Russia, earlier M-46 cannons were noticed on the road near Novocherkassk. It is unknown whether the Russian army began to use these guns, but it was previously reported that the guns are used in Ukraine. Presumably, shells for them can be supplied to Russia from Iran and North Korea. M-46 guns entered service with the USSR in 1951; for its time it was one of the best artillery pieces. Despite their age, these guns under different indices and in a modernized video are now in service and storage in 40 countries; Ukraine uses them. The M-46 guns have a 55-caliber barrel and are capable of hitting targets at a range of up to 27 kilometers with a conventional projectile and active-missile projectiles at a range of up to 37 kilometers. When using Chinese and Iranian active missiles, the firing range reaches 44 kilometers. The gun's rate of fire is up to 8 rounds per minute, with separate cartridge loading. The gun crew consists of 9 people, the transfer time from traveling to firing position is 8 minutes. The weight of the gun in the stowed position is 8450 kg. According to some estimates, there are about 600-700 M-46 guns in the warehouses of the Russian army.

Why were there not newer guns of these types? The type not a howitzer, but a more direct arc of fire.

The Soviet Union just like the West, placed their eggs on the howitzer, and the SU moved to the 122mm D-30 and the 152mm D-20. Despite this, the ranges achieved with the M-46 is obscene, 27km for the general projectile and 40km for the base bleed which exceeds the D-20 and matched with the heavier, bulkier Giatsint-B.

It's like all of sudden, the M-46 was rediscovered, partly in due that North Korea has large stocks of the shells, and to add, the DPRK ammunition is newer and has improved performance over the Russian stocks, which can mean they can exceed 40km with the base bleed. The gun is also dead accurate, and for that it's deadly in counterbattery warfare even without using guided ammunition.

Didnt they try to buy LHD from France? I can't see why they would not buy from China if they think they need it.

China won't be exporting weapons to Russia near term. And Russia is building its own LHDs at Zalyv Shipbuilding Yard in Kerch, Crimea.

They did buy from France, but got sanctioned and refunded, and are now building two Project 23900 of their own. Russia at the time was trying to buy Western product in an attempt to be "accepted" as a partner by the West. They were buying turboshafts such as in the case of their Ka-226 and Ansat, but have now developed better engines for both since the divorce. Also worth mentioning that Russia and China intentionally don't cooperate militarily beyond exercises to avoid spooking Western powers into escalating their own cooperation and binge sanctioning everyone.

Russia in Soviet times delegated medium/heavy helicopter engine manufacture to Ukraine. Medium/light helicopters and their engines were made in Poland.

Those countries produced those engines based on Soviet designs made in the Russian SSR. Even the Polish helicopters were mostly based on Soviet Russian designs like the Mi-2. Now that they won't sell to Russia, the Russians just made factories to produce their own engines like the VK-2500. Eventually also the VK-650 and VK-1600 for light and medium helicopters. It did not take much effort to design the VK-650 and VK-1600 since most competition (Pratt & Whitney) uses engines originally designed like half a century ago. Modern design methodologies also shorten the engine design cycle (computer design, simulation, 3D printing, etc). But it still takes time to test and certify an engine, plus put it in serial production.

Russia is still exceptional in that they develop their own attack, transport, recon helicopters, and their subsystems and armaments, their own surface and subsurface combatants to escort these LPDs, so it would make sense for Russia to buy LPDs from a foreign manufacturer. I don't know many countries that posses this infrastructure. This is easily a multi-billion dollar undertaking for the purchasing customer, and that is why I don't think LPDs are a feasible export product.

China already exported an LPD to Thailand. A couple other countries operate carriers so an export isn't impossible but the market is kinda limited. Maybe Indonesia.
