Based on the angle, the explosion and flight path of the helicopter we conclude that this is the same helicopter and the same incident.
This allowed us to do a triangulation.

In the afternoon other interesting footage emerged.
Footage from USVs (Unmanned Surface Vehicle) that were roaming the harbor and the sea near Sevastopol.
Here one was targeted by a helicopter.
Video 04
12/
In this frame we see the USV hunting for a ship (red) and fired upon (light blue) by the helicopter (Blue), probably an Mi-8 HIP.
The ship is moving from left to right.
13/
In this frame we see the ship moving from right to left and it is closer then the previous frame.
It looks like the helicopter dropped a kind of explosive and the footage stops.
The footage is not mirrored (see the screws)

Video 05
This is likely the same incident filmed from the shoreline.
A ship tried to escape and a helicopter is trying to shoot something in the water.

Video 06
In this footage we see a USV filming the attack on probably another USV.

Video 07
In this footage we see a USV filming the attack on probably another USV. The same or another one is unclear. At 06 seconds you see in the left corner the explosion.
17/
Here you see the explosion.
18/
In this video you see the attack on an Admiral Grigorovich-class frigate. According to @CovertShores (9 May 22) only the Admiral Makarov matches this class for the Black Sea fleet.
The footage stops when the USV seems to impact on the vessel, it likely exploded.
In this video you can see the attack on a Natya class minesweeper, Soviet designation Project 266M Akvamarin.
According to Russian MOD the Ivan Golubets received "minor" damage.
The footage stops when the USV seems to impact on the vessel, the USV likely exploded.
In this video you can see another USV roaming between the docked ships inside the harbor, probably looking for a target of opportunity.
The footage stops when the USV seems to impact on a vessel, the USV likely exploded.

The USV was really inside the harbor between the ships looking for his target.
Based on the footage we can conclude that it was near at least 4 ships and for attacking the target it did almost a U turn.

What kind of USV was used by Ukraine?
For this we totally agree with @CovertShores' conclusion 👇
"21 1640 SEP - GEO - VID - Russian sources reported that this afternoon, an object resembling an unmanned surface vehicle of some kind washed up on the shore of Sevastopol."
Based on all the footage we estimate at least between 6 and 8.
- 3 Were used on ships
- 3 were roaming 'in daylight' in 'open' water.
- 2 were destroyed (Can't exclude those are the same as the roaming ones.)
29/
How can we asses this number?
An USV his camera is fixed, really hard, needed to counter the impact of the waves. Based on the width of the screen and the position of the angle to the screws you can see the difference.
3 were used in the early morning, 3 during daylight.
30/
In one of the video's (Video 02) you see anti-air shooting.
This could point to the fact that also UAV are used, until now we didn't found any proof of that.

Anyone who watched today's newsfeed knows that certain video's/images are not in this thread yet.
Their is a reason for that.
Black smoke 01.
POV = 44.570300, 33.409081
Location Smoke around = 44.58076, 33.41561
So why is this not relevant...based on the footage that emerged around noon -as far as we know- this smoke was part of an exercise where they burned tires. (black smoke)
38/
But why would you do an exercise... with a naval vessel... after your fleet is attacked... with a lot of smoke 🤔
The only reason you would do that is to get information in the open and distract the attention from the attacks.
(Old?) footage from the same area:
39/
According to the Russian MOD all the ships that were attacked were involved in ensuring the 'grain corridor' and they have now suspended the 'grain deal'.
So what kind of fleet protects it's shipping routes from inside it's harbor? 🤔
Based on all available footage, it's highly likely that:
1. USV's penetrated THE Sevastopol harbor defense 2. > 6 USV's were used 3. At least 3 ships were struck with an USV 4. The presumed dolphins didn't do their job 5. Swimming > USV encounter.
"Russians leaving their defensive position in panic, get as much soldiers as they can on top of their armored vehicle to crash 630 meters further."
(01 1513 OCT)
Same location:
"06 1349 APR - GEO - UAV - 2 days ago, the Operational Command "East" of the Ukrainian Army posted video that claimed to show "over 40" Russian vehicles destroyed by Ukrainian Artillery fire on a Russian rear base."
