Questions and Ideas

At subs are used wired torpedos? Informations could be transmitted trought.

Yes, there are plenty of subs that still use wire guided torpedoes.

For short range weapons it means that the sub can use its enormous sonar to detect and follow the target at extended ranges than would be possible with the tiny sonar array on even a modern torpedo.

Basically the sub detects the target and launches the torpedo and sends course corrections to the torpedo via the wire link until the torpedo hits the target or it gets close enough to detect the target itself with its own sonar... either in passive or active mode. The wire is then cut and the sub is free to manouver again while the torpedo guides to the target on its own.

Also missiles could be carryed by a torpedo engine till surface then the engine could start so that the missiles could be launched from deep water. Torpedo engines would be dropped at surface

Missiles are generally fired by compressed air out of its tube just like a torpedo. The buoyancy of the missile usually allows it to reach the surface on its own without need for a separate engine... once it reaches the surface usually a solid rocket motor launches the missile clear of the water and up to a speed where a flight can be assured with the onboard small turbojet engine.

Or a tank whit air that carry the missile at surface

A tank with air would drag the missile to the surface, but would take up a lot of space within the launch tube, which means smaller missiles which means less performance for something that will be dumped just after launch.

I read that instead of MIRV are used now hipersonic vehicles

Russia has introduced hypersonic vehicles instead of MIRVs because when the Soviet Union split and Russia was left with all of the former Soviet Unions ICBMs and SLBMs, it found that many of its weapons were made or had lots of parts made in other new countries. For instance the Ukraine had many companies that made parts of Soviet missiles, so the first priority was to develop new all Russian missiles so their design was not compromised and sold to the west.

Because they were making new missiles they could devote money and effort to developing new reentry vehicles and as the US was working on ABM systems it made sense to develop hypersonic reentry vehicles that could manouver to evade an ABM system. The US does not have hypersonic reentry vehicles because it has not been building new ICBMs and SLBMs, but over the next decade or two they will likely start doing the same as Russia develops its ABM capability.

For the very corosive liquid ICBMs fuel bricks can be used or stone

AFAIK the liquids in Russian ICBMs are fully storable and the missiles can remain fully fuelled for the life of the missile safely.

Fuel tanks can be filled whit the guel by tubes trought the edge of the fuel. I think at some flexible tubes

Most synthetic flexible tubes perish over time and would likely not be suitable for storable fuels.

They might be defuelled for periodic maintainence which makes them much much lighter if they have to be removed and also much safer if they have to be removed from their silos, but I suspect most of the time they would keep the fuel in the tanks and just remove and inspect the warhead and guidance sections as needed.

I saw once a strange thing : a triangle from wire whit electrical curent trought lift off from ground. A missile whit that tehnology can be made? Whit the wires inside and holes to the head and tail of rocket

Have you seen lanterns where you set fire to the bottom and as they burn hot air is trapped and lifts the lantern off the ground and they fly away.

neat trick, but not really very practical for a flying device except hot air balloon.

So how they do thatenemy torpedos evade this kind of torps?

Russian vessels already use RBU-6000 and PAKET-NK for anti torpedo use.. former is depth charge thrower and latter is anti torpedo torpedo.

They say russian subs are old and noisy but what is important that a sub can detect and anihilate a threat.

Ridiculous blanket statement... Is Borei or Yasen old? Or Improved Kilo? "They" are clearly idiots.

Subs don't have to move... remaining stationary makes very little noise. Diesel electrics are noisy when snorkling and recharging their batteries, but when running on electric motors they make rather less noise than any nuke powered sub...

Point was that maibe the missiles could be launched from very deep thus more safety for sub and more chances to launch all missiles in time.

What sort of missiles are we talking about?

SLBMs and cruise missiles make more sense being launched near the surface as the sub can stream an antenna and pick up orders/instructions/target data from satellites or nearby friendly aircraft.

ABM stands for? Ill try to find a military acronims dictionary.

Anti ballistic Missile.

Getting out and refuel missile when needed would increase time of launch
the point was that sintetic tubes to be put from outside and mounted

Actually liquid fuelled missiles are much easier to handle than solid fuelled missiles... just pressurise them with compressed air and load them into the launch tubes of the SSBN as they will be light and not full of dangerous chemicals. Once loaded into the tubes attach hoses and pump out the compressed gas and replace it with the storable liquid propellents, which will remain in the missiles while the sub is at sea. When the sub ends its tour just pump out the fuel and remove the missiles.

A 100 ton missile will be about 90% fuel by weight so when you take out the liquid fuel it will be 10-15 tons, which is much easier to move around and handle with no risk of fire.

I dont know if i asked but: a airscrew can be used to power up a electric generator in a aircraft fighter? The air spin the airscrew very fast which spin the generator very fast ans thus you have enough energy for same like AESA radar. There you go simply and enough for what its needed. The blades from jet engine could be used.

Most modern jet engines have electric generators built in to them and a separate auxhilary power unit or APU to run aircraft systems on the ground without the engine running and to start the engines.

Some very old WWII bombers had exernal propellers that used airflow to generate power and some modern external pods also have fan blades on the nose to do the same...

Same principle can be used in a missile whit blades that spin because of the air and spin a generator. Which would extend radar of missile

Usually more efficient to use a battery. With a supersonic rocket the propeller would not work very efficiently and might just break and cause a lot of drag. In comparison a battery is more reliable at any speed.

Did someone know if is true that photons imprime speed to objects? I saw on internet a airscrew that was spinned by a photons of laser. This could help to spin a generator very fast.

Would likely not generate more energy than it uses. the amount of force light exerts is tiny and would need days to gather speed in deep space outside the gravity wells of earth and the moon.

A solar wind can move a airscrew half inside the satellite which would spin a generator

Only well beyond earths magnetic field where there are very few satellites. The actual force of the solar wind makes it interesting for an enormous solar sail like several kms in area, but for a propeller it simply isn't dense enough to be practical.

Why subs dont have torpedo chambers in all his parts?

Because it takes up space needed for other things.

Some subs have front and rear tubes and vertical tubes are popular now too, but it makes more sense to carry more spare torpedoes per tube rather than dozens of tubes but no spare space for extra torpedoes.

Sonar arrays are currently all over modern SSNs.
