Is this an option for the Russian navy?
Airships are not good in very high winds, but are much safer than one might think.
Most laymen think of the Hindenberg and remember a big fireball, but in reality a modern airship made of carbon fibre and other very light weight strong composite materials that dont burn well and fill it with helium which also does not burn and it would actually be quite hard to bring such an airship down with conventional weapons.
The main problem is ballast... when you have a transport airship you fly it to where the cargo is and then you have to load the payload on, while dropping the ballast until you have a full payload and fuel to get to the destination.
Now lets imagine you are building a dam in the middle of nowhere... no airfields, no roads... nothing. Build a huge airship that can carry oddly shaped 1,000 ton payloads under it and it can go to where it is made... pick it up vertically and take it directly to the dam and lower it into place. Most other forms of transport you would need to take it to pieces and transport it in thousands of separate loads and then assemble it again.
The main problem with such an airship is that when it takes on the load it has to drop 1,000 tons of ballast, but when it travels to the delivery site it will burn fuel which means it needs some way of taking on more ballast in flight... or it has to reduce its lifting capacity on the way otherwise it will just get lighter and lighter and be unable to land.
In the past the changes in weight were dealt with by releasing hydrogen but in a helium balloon helium is expensive, so some form of fuel cell technology that can turn hydrogen into water and water into hydrogen should offer much more flexibility... hydrogen is very cheap and readily available and lighter than helium so a better lifting gas so could form the core of the lifting gas on board the ship down the centre surrounded by inert nitrogen to prevent fires with helium around the outside which is also inert.
Radar arrays could be part of the structure and could be enormous and make stealth even B-2 stealth ineffective...
The Russians have already sold airships to China for radar monitoring of mountainous terrain and communications relay with unmanned airships operating for months at a time.
And do you know if they are installing cars on the K?
It would be useful to put them into service and get some experience with them. EM cats make more sense as they can be smart cats where the power can be adjusted during the launch to ensure safety.
Often with steam cats someone made a mistake in the calculations and a heavily loaded heavy aircraft didn't get a high enough setting on the cat to get airborne and ended up in the water. An EM cat could self adjust during the launch to ensure safe takeoff speeds without ripping off the front wheel assembly.
I heard they can put a VERY POWERULL radar on rhe mig-29k so it is kinda an awacs plane.
Radar power is good, but very large radar antenna offers better performance and 360 degree views, plus a large plane with longer flight endurance is also a very good thing too.
BTW add a tail facing Antenna array and the PAK FA already has 360 degree radar coverage, but a dedicated AWACS aircraft is still worthwhile IMHO.
