S-70 "Okhotnik" UCAV

If they intend to use non after burning engines then it would be purely subsonic only... which would mean why no use the engines currently being used... I doubt the difference in performance would be enormous and it would be a useful way of using these engines in current Su-57s that are to be replaced as soon as the new engine is deemed to be ready.

What do you mean by "engines being currently used"? Izd. 117 is currently being used, but they need a version w/o AB so that needs to be created specifically for the Okhotnik. The izd. 117 has been taken to serial production and we hear about a new engine for the Flankers, so maybe it is going to be the baseline engine for the VKS. Of course it makes sense to use it rather than older AL-31F engines, it has a longer lifetime and much better performance, and the industrial base in Russia needs to move forward from engines created 40 years ago.

So I might be correct from earlier post that it is for landing, similar to the sensor on the left missile bay root sensor on the su-57?

The Su-57 and S-70 currently use an engine and soon a new more powerful engine will be introduced to improve the performance of the Su-57.

The difference in performance wont be relevant to the S-70 so why no use the currently used engines on the S-70 and put all the brand new engines in the new Su-57s and also any that have already been produced when they start making them.

You don't need an expensive state of the art jet engine in a drone.

You don't want to increase the cost of your drones with brand new expensive engines whose ABs are removed anyway.

That is assuming the new engines are more expensive. They might be cheaper.
The trend is towards machine controlled fabrication and 3d printing which means machine have less parts.
Hence less assembly time and cheaper costs overall.

As far as I know that is precisely the plan, maybe not the part of "recycling" engines used in the Su-57, because those in the S-70 are a different version, but yeah, the Okhotnik will use the izd. 117, specifically the izd. 117BD

GarryB wrote:My understanding was that the S-70 engine was just an Su-57 engine with the AB removed... a bit like a motor car engine used in a van and a car but with the van a turbocharger is fitted to boost power, while in the car the turbocharger is removed because it does not need the extra power... but both have the same engine otherwise which has advantages of spare parts commonality and using the same engine manual etc etc.

Would also make sense if the S-70 is also operated by Su-30 and Su-35 aircraft also using the same engines.

GarryB wrote:It has interesting potential, and when used with upgraded Su-30s which would essentially be two seat Su-35s, and of course MiG-35s in the two seat layout, perhaps they could operate more than one or two.

GarryB wrote:I understand that, but I think an aircraft with two crew could manage more drones and use them in groupings and make them more useful than one or two drones that a pilot uses while flying his aircraft.

Not like they haven't done it before... the Ka-52 can launch and control UAVs to scout ahead with suicide drones.

Yet no known 5G plane is slated for having a crew of more than one.

I'm sure this is some joke between Sukoi and the CIA. In the picture the silhouette of the S-70 is clearly mimicked on the back of #053 and has been there way before the S-70's first flight.

The Su-57 next to #053 is most likely #055 I would guess, but the outline was a bit blurred in a later paint job. Initially the #055 had a very clear silhouette on it's back depicting some unknown stealthy design.

If I have to guess it may well be some black project from Area-51
