the moon landing was basically conducted on an 8kb computer
And the Memdelev Table was also developed without computers... what is your point?
My point is that even a bog standard Mig-29 uses 486 level computer hardware, so what is all this crap about the F-22 being a super computer with wings?
bigger and fatter bandwidth is not automatically better especially for fighters.
Most word processing and email that people do now on 8 core 3.5 GHz computers is not hugely different from the sort of thing they could have done in the 1980s on an Amiga 500 at something like 7.4 MHz clock speed.
As you point out there is a difference between military and commercial, but a faster higher performance processor operating in a larger bandwidth has very important flow on effects in terms of capabilities.
If you want sensor fusion then you need a system that can in real time combine raw data coming in from multiple sources (RHAW, IR sensors, Radar, and off platform sources and combine it all into a real time picture of everything around the aircraft.
An 8 bit or 16 bit architecture will limit the number of memory addresses... even in a 32 bit environment Windows cannot recognise more than about 3 GB of RAM, which might not sound like a big deal but the amount of data a modern AESA radar can generate means you need as much grunt as you can get.
Just as an example the original ZASLON radar of the Mig-31 was a very powerful set and its volume of scanning was enormous, but its range was not very impressive because of a lack of processing power.
The current upgrades AFAIK use the same radar with the same antenna with almost double the range because of a much more powerful radar.
A dedicated processor that is hard wired to a task doesn't need to be fast... do a search on my chats with Flanky about UAVs taking over the role of JSTARS in the Russian Air Force and even my chats with Vlad about making computer chips.
A calculator can have a very slow processor but still do the job of calculations very very quickly, the problem is that in the 1980s as processors got faster the computers in military equipment moved from pretty much custom designed chips used for specific roles in specific aircraft where an upgrade means a whole new chip and hardware needs to be developed to a generic off the shelf chip where upgrades are just a question of a software patch or upgrade.
because in combat you don't need it - you only want and need to track the object of interest that does not require huge bandwidth
Again, this us supposed to be the best of the best... some even claim it should be called a 6th gen fighter because it is so much better than 4th gen fighters...
the Mig29 HMS doesn't give a cue as to what the missile is locked to - certainly it was true of the former East German airframes - there's a very comprehensive description of operations with the Mig29 by a US pilot floating around, and it's quite illuminating as to how crude the whole thing is compared to western aircraft.
What a load of rubbish. Looking through the glass monocle the pilot sees a reticle or aiming sight pattern and to use it he turns his head to put the target aircraft in the centre of the reticle and presses a button on his control stick which slaves the selected missiles seeker to his line of sight, so it turns to where he is looking and gets a lock on that target. When lock is acquired the pilot is free to pull the trigger and launch the missile.
When this system entered service his NATO equivalent looked around in the sky for the enemy and when he located them he had to turn his entire aircraft to point his nose at the target and then activate his missile seeker to scan for the target. If there is a group of targets EVEN IF HE GETS A RADAR LOCK that means nothing because there is no link between his radar and his IR guided missiles so his radar might lock on one target and his IR guided missile might lock on a different target altogether...
It is amusing the west calls the Soviet system crude because the US equivalent didn't enter service till at least 20 years later, has no clear advantages over the Soviet system though it is heavier, more complex and orders of magnitude more expensive so only a small percentage of US fighters actually have it... and that does not include their F-22s. On the other hand every model from the oldest to the newest Mig-29 and Su-27 have it fitted as standard.
Also what is not widely recognised is that the R-27T and R-27ET are also high off boresight IR guided AAMs which benefit from the helmet mounted sight...
I'd suggest training (western jet operators spend a lot of time and money in putting their stuff into the sky in large, well scriped DACT exercises), and situational awareness (both inside the cockpit and out!) are both more relevant than how many gigaflops are on tap.
I'd suggest that it is par for the course... the Super aerial Cray computer is actually a white elephant that will likely be a hangar queen for some time to come...
consider that the F-16s flew in "clean" condition while the MiGs had six pylons and carried a centreline drop tank and two fixed R-73 acquisition rounds "
A....little detail Very Happy .
To be clear the use of the centreline drop tank on an early model Mig-29 is for ferrying ONLY and limits the aircraft to something like 4g flight performance.
Simple but equally effective weapon costs much less over the service lifetime cost. Indians are buying Su-30s w/AESA and total cost for 40 birds comes to $4B odd at $104M per unit. However these include the lifetime service costs. People tend to go with initial flyaway price which should be $30-40M for Su-30s and spread stories that Russians are trying to defraud Indian Air Force.
The contents of that contract have not been revealed AFAIK, for all we know the $4B dollars could cover the price of the 40 new Su-30s with AESA plus an upgrade of existing aircraft to that standard. They equally could have ordered new simulators, or they might simply have included a large order of spare parts and weapons for their whole fleet with those 40 new aircraft.
