RE: FPV for Search & Rescue mission
What you are contemplating is autonomous flight. If you type in “autonomous flight competitions” in your search engine you will come up with tons of links to university competitions. Many are short indoor but there are a few links to out of sight flight.
That being said five things you will have to overcome. Launch from an unstable moving base, recovery to same, platform able to handle high winds and carry enough batteries for time in air, range and location.
Hand launching is marginal some sort of catapult launcher would be more consistent.
Recovery could be a large catch net of some sort as your base would be constantly moving and most likely pitching in rough seas.
Something streamlined and slippery like a glider but capable of handling higher than average speeds with a large enough fuselage to carry everything. Electric twin engine for redundancy, folding props with one engine having enough power to fly the aircraft. This might take the shape of a tandem boom with a larger streamlined center pod with engines in line one puller one pusher. Both engines running on take off to overcome wind and get the aircraft to height. Both engines might be needed to fly into a strong head wind the rest of the time or in case of engine failure one engine could fly the aircraft. On landing into a cargo style net the front engine could be shut down and the pusher engine could fly it into the net.
The platform should be big enough that at least 3 cameras could be employed. One fixed and two operated by separate operators during the search.
Some ideas I have been kicking around for a few years. Like the rest of us if you really want to do this you will have to do the research yourself.
As to making a bomb out of the thing it’s already been tried and isn’t reliable enough to be worth the effort. In most cases the payload is not great enough and targeting is not definitive enough to make use of the small payload.
Using a foam platform for something like this tells me you have little knowledge as to the demands that will be put on such a purpose built airframe. That thing is a toy you will need to build something out of material that will take one hell of a beating and still function.
