Oryx commentors on twitter are all retarded anti Turkish liberals who only support the current thing.
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.
Yes there is and I watched that video. but I didn't see anything hit. or the target was unclear. They were just shouting.There is a video of ukrainians downing one cruise missile with manpad
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).
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.
Interesting to see an Azeri to support Russia so eagerly after years of support of Russia to Armenia.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.
I had to write again. First, there is no nation called Azeri. People living in Azerbaijan are Türk like Anatolian people.Interesting to see an Azeri to support Russia so eagerly after years of support of Russia to Armenia.
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.

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.
The U.S. have also committed eight NASAMS and associated munitions, and two of those will be in Ukraine in the very near future, with six more to be provided later
I know Turks who supports pkk, DAESH, Hezbollah, Israel, Russia, USA, China...Interesting to see an Azeri to support Russia so eagerly after years of support of Russia to Armenia.
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).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".
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.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:
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 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.
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)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.
