They had ~20 active S-400 systems (complete) a few months back, probably a little less now, but enough component parts from S-300 systems to build around 200, though a caveat there they may not be able to get hold of some of the parts required to build them to the same spec as the existing active S-400 systems which may be why they are moving systems around rather than replacing them from central stockpiles.

EDIT: That doesn't include complete S-400 systems in storage, but no one seems to have any data on that - they might not even exist - it looks like they were built as required for active systems by upgrading S-300 systems.

EDIT2: Several sources cite Russia having 96 complete systems at the start of 2023 (original source seems to be International Institute for Strategic Studies) - which would likely mean they have somewhere around 60-70 still somewhere in some form of storage but again can't find any evidence they actually exist.

Quite possibly at least some of those have been cannibalised to keep the ones that are known about running, especially if maintenance before the invasion wasn't done well and parts were nearing their EOL or simply shortened due to a lack of routine maintenance. I can quite see a situation where they need parts to keep a front line unit running and can't get "new" spares, so they pull them from units in storage that might have been awaiting a larger maintenance job (so something needing an engine or generator overhaul gets a control board pulled as it's quicker and simpler to do that and ship it out than get a stored unit running).

Ukraine has launched a open source public database to track foreign components in Russian and Iranian weapons


For example, here is a Xilinx FPGA chip found from Russian X101 cruise missiles

Xilinx is owned by AMD

Be interesting whether the dev board/kit was used (mentions Board BT33-202 in the listing) or the chip implemented into a circuit - there is probably a dozen industrial appliances which use that FPGA they could purchase to salvage them from which would be hard to deal with via export controls, etc.
 
Whilst AMD did acquire Xilinx last year. The FPGA's in question are from around 2003 (20 years ago). The issue with FPGA's is that they can be re-purposed from one specialist task to another. (Hence the name Field Programable Gate Array). This is why there was talk of Russia salvaging components from domestic goods such as washing machines last year. You will find FPGA's inside all types of devices, vehicles, set top box's, domestic appliances, medical tools, even the space station. It's not an easy task to do export controls, let alone track and control components from 2 decades ago which likely have been salvaged from other benign sources.

All that said, it isn't good that Russia can get their hands on them.

I caught a segment of the evening news where they were interviewing Russians who seemed to be of the view that there was no real alternative to vote for other than Putin. And they do have a point. Why would you want to vote for a candidate who can't even run an election campaign without falling out of a window, ingesting a lethal amount of heavy metals or shooting themselves twice in the back of the head?
 
Russia says they will be forced to us the SU-57 against the F16s. Apparently Russia is quite concerned that its other planes will get their **** rocked so their head of aerospace forces says they will deploy the SU-57 as soon as Ukraine gets the F16

This SU-57 is currently out of action though

That a recent image? Has another one caught fire?

Also I though they already claimed the SU-57s are operational and flying missions over Ukraine

All 4 of them?

The reason interrogators ask the same set of questions for hours and sometimes days at a time is because a liar will eventually change his story and you will know he's lying, whereas an innocent man has nothing to change.

The reason interrogators ask the same set of questions for hours is that they're bad at interrogating. Innocent people will also change their stories if you pressure them enough.

Again unfortunately that's probably bird strikes.

Both engines at once suggest it's not a maintainance fault, and the pop pop pop type effect IIRC indicates something has happened to the compressor/turbine and the most common thing to do that especially to multiple engines at once is something entering the intakes from outside, and that is most commonly birdies.

Still not good for Russian aviation as that's likely two complete engines out of action as it likely requires a thorough inspection and overhaul with at the least some replacement parts - they may be able to fly it again without replacing some bits that might be routinely done (and required if going by the manufacturers book), but if they do they'll be flying with some now very suspect engines.

Russia is basically facing all the "normal" aviation issues, but few parts to get aircraft back up and running again, so whilst this probably wasn't a failure due to maintenance, it is going to be much harder to fix than it would normally be as under normal circumstance the operator would likely have a replacement pair of engines fitted within a few days, if not over night as they keep spares specifically for this situation.
