There are many immigrants in Turkey. Afghan, Syrian, African. In fact, it would be good if we could make a campaign with the Russians or Ukraine and make those immigrants give their military service in exchange for the citizenship of the country they are fighting.

There is a video of ukrainians downing one cruise missile with manpad

Yes there is and I watched that video. but I didn't see anything hit. or the target was unclear. They were just shouting.

Just yesterday, the Ukrainian side said that we shot down many cruise missiles. Many videos have been released. But the goals in these videos are not clear.

So in a propaganda war with so many fictional videos, I don't believe them either.

There are already many target shooting videos for Russian fans.

In other words, I think the news that 44 cruise missiles were hit is a propaganda lie.

Contact fuses is the key here, they should explain themselves how it works. I totally agree with this last point, you shoulnd't have them if your intention is to explode the charge underneath the ship.

My guessing for a hypothetical updated version would be a predicted action based on it's computer rather than a fully unmaned submarine device. How it should look like IMO?

Assuming the device contains a logic chip/CPU with it's embeded SO, you may create an algorithm which calculates the exact or approximate maneuver the USV should do to perform this action.

-Assuming that the USV has a relatively effective way by itself to estimate the range to the target (laser, cameras, gps?).
-Main variable would be the profile of the ship to attack, ( span and draft ?) it should be relatively easy to get that data and select it from remote.
-You can get location, speed and slope from your own sensors, so you can calculate the whole maneuver to be done, adjusted from previous tests.

So...

-You won't need huge stabilizers, although fixed fins are not seen on the pictures we have, it can be done with moving fins mixed with fixed ones deployed at the moment of the triggered action.
-About intake, should be good to go with an oxigen tank, as stated before. Exhaust, just as sailboats, wet exhausts. It just needs a few seconds to make the effect.
-Internal tanks to be filled, they could take advantage of internal water stream to the engine refrigeration system, for filling them up without needing any additional pump.

Then basically when you trigger the action of "armed" it should be smart enough to submerge 10-15 meters underneath the ship when it stimates it's near enough.
Additional technology could be only for deployed/fins and watertight internal gates. In my opinion completely feasible archievement.

INS could work for that purpose and they may couple an expected rendezvous point based algorithm with a simple detonation mechanism extracted from an old torpedo. However, it will still require some horizontal stabilizers to keep a stable depth, those can be added to the forward section for more aggressive maneuvers, rear section for more stable ones, still at least needs 2 of them or a single whole length flap on the stern (or thrusters as i am suggesting in the latter part).

Since it utilizes a water-jet propulsion which will be ineffective once it is full submerged, they will either need to use propeller-shafting with diesel engine (thus the O2 tanks) or dual mode propulsion by switching to battery-thruster once submerged. They may use rear-added external engines-propellers and add a switch to change between O2 tanks and a short snorkel (to keep air intake a bit higher than the surface). With this way, they can make a space for the ballast tanks. Such engines would work fully submerged as long as it is fed with the air since they use propeller hub as the exhaust (thus, less complication compared to a wet-exhaust setup).

Also needs a good optimization for balancing the ballast & free-board. A very low free-board may adversely affect sea-keeping capabilities that will likely cause the vessel to be immobilized by submersion of the water-jet propulsion.

So, they may switch to external-mounted engines utilize the emptied space of diesel engine and water-jet propulsion for batteries, electric thrusters and ballast tanks. With this way, they will not require additional control surfaces and use thrusters to maneuver around (simplifies the control algorithm as well).

From my point of view they are tight on the space and may not have an option to reduce freeboard and add some ballast tanks to flood, so moving engine to the rear and switching to good old external engines might help a lot, to begin with. Also they may have a way to "jettison" the external engines and ease the underwater motions too.

I am more curious about operational depth of the starlink terminal, how deep in water that would be able to transfer some data?

So in the end; we need an old torpedoe's detonation mechanism, a pressure-gauge to estimate the depth, cheap 1D sonar pinger to measure the forward distance with the target, a cheap but sufficiently good INS, 2 rear added engines, 2-3 thrusters directly coupled to batteries, a fairing on top to reduce hydrodynamic drag.

Seems to doable to me and would take about 2 weeks to complete such a modification mainly using COTS equipment.

Interesting to see an Azeri to support Russia so eagerly after years of support of Russia to Armenia.

I had to write again. First, there is no nation called Azeri. People living in Azerbaijan are Türk like Anatolian people.

Secondly, I do not support Russia. I just do not want Russia to disintegrate for now so that the balance of power in our region is not disturbed.

Because if Russia disintegrates now, the USA will take over our country and the north of the Black Sea.

Because of this danger, I do not want Ukraine to win. that is, out of necessity.

Really good additions. My doubts are about why the water-jet system will be ineffective once it is fully submerged, if the engine keeps running, then it could keep accelerating the water through the system and propelling the "weapon".

According to H I Sutton, in this video, min 11:15, the engine could be a ROTAX 1630 ACE, a marine engine running on regular gasoline. I've made this quick schema to represent the idea of the *new* system:

Hope that's the air intake, hehe, but it should represent how it could work for a couple of seconds. There are some "toys" which are using the snorkel you mentioned. Would be the propulsion ineffective even when the engine is running? It seems some submarines use it.

For stabilization and underwater maneuverability, it could use retractable stabilizers, being controlled by the main computer and powered by it's engine either using hydraulics or electric motors, rellying it's movement logic to different sensors. I think using your proposed solution, should be a really good idea, old torpedo sensors/systems could be easily adapted . And in front part we can have some small "fixed" and retractable fins.
Pumping water to well shaped/placed ballast tanks will reduce speed and help maneuverability once the "firing" action is triggered making the system more stable and easy to control.

Well, comms won't be needed on the system as it would rely on a pre-scripted action, which considers all these factors, including target shape, profile, etc., so it will know how to perform them by itself. As GPS case, I think comms would be broken as radio waves would be "absorved" by the water, but hopefully we will have a big water splash captured by a Bayraktar.

My doubts are about why the water-jet system will be ineffective once it is fully submerged, if the engine keeps running, then it could keep accelerating the water through the system and propelling the "weapon".

Unless we are mentioning about pump-jet or thruster kind of "jet" propulsion, the water-jet propulsion relies on the principal that water is accelerated and pushed out into the air. If you carefully look, all boats equipped with water-jet spray the jet towards the air instead of the water and usually semi-wet or all wet in the rest condition, and as the vessel gaining speed, the water-jet nozzle gets fully dry, i.e. the negative pressure at the stern area sucks the water downward and causes stern area to "dry". So, a typical water-jet propulsion would loose its efficiency once fully submerged (the rotor would face a remarkable resistance - instead pushing towards the air vs water, likely ending up with overload in torque on the bearings and causing waterproof seal to leak).

However there are other kind of jet propulsion; called pump-jet which is used in submarine, torpedoes or thrusters which we also refer as "propeller with nozzles". The main difference relies on the design of the stator-rotor configuration and blade geometry.

According to H I Sutton, in this video, min 11:15, the engine could be a ROTAX 1630 ACE, a marine engine running on regular gasoline. I've made this quick schema to represent the idea of the *new* system:

I think the ballast tanks better be placed above the water. inside a fairing, allowing water to rush in and out like good old u-boats. Also would move the buoyancy center higher thus resulting in a stable submerged configuration.

For stabilization and underwater maneuverability, it could use retractable stabilizers, being controlled by the main computer and powered by it's engine either using hydraulics or electric motors, rellying it's movement logic to different sensors. I think using your proposed solution, should be a really good idea, old torpedo sensors/systems could be easily adapted . And in front part we can have some small "fixed" and retractable fins.

This is an option, but i would still prefer a 2-4 electrical motor thrusters instead of stabilizer fins. However, even a single flap at the stern would be serving the purpose for depth adjustment if the boat is stable under the water (ie. center of buoyancy rests above the center of mass).

For example see:

These motors do not require a major penetration, or a space within the hull except of the connectors, merely connected via a cable, no hydraulics, easy to access-purchase, and only requires a cable and feeds from DC source, directly on top of that driven by simple controllers. Also it is pretty cheap.

So,i am more on the side of using these outboard engines and then switching to electrical motors instead of using a snorkel. Since at the very last end, the snorkel may hit to the board of the target, since the clearance for the bubble-jet effect is few meters below the base, not 5+ - 10+ meters.

Thus not storing any fuel inside the hull and even "dropping" the engines once the target is reached.

Pumping water to well shaped/placed ballast tanks will reduce speed and help maneuverability once the "firing" action is triggered making the system more stable and easy to control.

These will be needed somehow, they may either add a fixed valve that is once broken and flooding a section or the ballast tank (thus not recoverable and only one-way, fed through the positive pressure), where another timed valve is for security to permanently sink the boat if the target is not reached within an expected time. Since torpedo warheads are insensitive, unless it is armed then it wouldn't pose a risk for civilian traffic once it is fully sunk to the bottom of the sea.

With this way we have also solved the ethical end of the problem, the boat fully sinks if it exceeds the limits. Runs out of battery and sinks in disarmed state.

Well, comms won't be needed on the system as it would rely on a pre-scripted action, which considers all these factors, including target shape, profile, etc., so it will know how to perform them by itself. As GPS case, I think comms would be broken as radio waves would be "absorved" by the water, but hopefully we will have a big water splash captured by a Bayraktar.

I was rather curious how far starlink can remain up, 1 meter of depth, or 2? That would allow the vessel to sneak close remaining uneffected from the waves with a more stable route at the terminal stage (last 2-3 kms)

The Armed Forces of Ukraine liberated 2,535 km² of Ukrainian territory in just one month.

The so called " rashists administration" of Kherson, was moved to Skadovsk , - the General Staff of the Armed Forces of Ukraine.

Let's move it to Moscow right away

Since the beginning of the war, Ukraine has received at least 41 billion euros in aid from Western countries.

CNN about new arm deliveries by Iran to Russia.

Approximately 1,000 ground-to-ground missiles and even more kamikaze drones.

40% of Ukrainian energy facilities damaged as a result of shelling by occupiers, thermal power plants, thermal power plants and hydroelectric power plants destroyed, - Zelensky

⚡️Ukrainians need to start preparing for a difficult winter now and stock up on the necessary things, - said Prime Minister Shmyhal

It's time to buy warm clothes, power banks and generators.

⚡️The head of the Kyiv OVA does not rule out that there will be no electricity for weeks

“If there are damages that we can repair in two weeks, this will indicate that we need to hold out for two weeks. If there are other damages, the repair process may take longer or, conversely, less,” Kuleba said. .

Ukrainians should always be ready for anything: keep your phones charged, stock up on food and water.

⚡️In the Kyiv region until November 15, 425 shelters for the population will be equipped in case of a nuclear threat, - the head of the OVA Kuleba

At the moment, the shelters are not completely ready, but they have ventilation, 2 entrances and exits, and they are located underground.

According to Kuleba, : "Most of them are radiation shelters. This is every second in the Kyiv region. They are more fortified, located at a greater depth."

US senator announces new $60 billion aid package to Ukraine

US senator spoke about the preparation of a new aid package to Ukraine for $60 billion

It is noted that this money will help cover some expenses for Ukraine.

US lawmakers are discussing a big new aid package for Ukraine, which should be voted on before January. Previously, the amount of 60 billion dollars is called.

Republican Congresswoman Adam Kinzinger spoke about this in an interview with the Voice of America.

"Voting for this package should take place before January. I assume that either at the beginning or in the middle of December. It all depends on how quickly we complete our work. I heard a figure of about 60 billion," the politician said.

“It should be noted here that this is not a blank check that we will just sign for Ukraine. These finances will be the corresponding amounts allocated during the next financial year. So this will reimburse the costs until September. We do not want to just give out huge amounts of money and not "We want to make sure there's accountability. So, if we can get this $60 billion package going, in case something extreme, unpredictable happens, those funds will help us get through at least the next fiscal year," Kinzinger said.
