IIRC its for EOD as rolling the bomb off the edge normally would have the bomb too close to the ships hull so they use ramps to throw it further away.

It's more like there's too many spots where UXO tipped off the deck edge can get hung up - catwalks, life rafts, sponsons, catch rails ... so there are designated spots which are clear of any potential obstructions.

It's basically a slide/access point for munitions to be tipped off the flight deck into the water if it is needed (such as if there is a fire on the deck or if there's been battle damage which may cause munitions to cook off and cause secondary explosions).
Yup 100%. This is even more so by the 'bomb farm' a staging area for munitions in the event of a serious FUBAR on the flight deck and you need to dump a bunch or ordnance overboard.

During the first sea trial on May 1-8, 2024, black smoke was emitted while sailing at high speed.(Two points in the video: around 1:40 and 5:30)

Can anyone please tell:
1. What is the reason for this?
2. Is it possible to adjust and solve the problem later?
3. What are the possible effects?

Thank you for your answers. (In case I forget)

When an engine suddenly transitions from low-speed to high-speed operation, there can be a temporary increase in black smoke due to the sudden increase in engine power demand. This can occur if the fuel supply does not immediately match the engine's requirements. This phenomenon is often referred to as fuel enrichment or over-fueling. In such cases, because of an excess of fuel or inadequate fuel-air mixture, some fuel may not fully combust, resulting in the production of black smoke. However, once the engine stabilizes and adjusts to the new load requirements, the black smoke typically decreases or disappears. This phenomenon is often observed during transient state changes and may be more common in new engines, especially during tuning and optimization phases.

Smoke is emitted when internal combustion engines are used, Hope this helps;)

This is nothing unusual. Engine startup and acceleration can cause transient rich fuel mixture, resulting in incomplete burn that produces black smoke. The smoke goes away after the mixture becomes optimal.
