Sorry sir - i don't have any other numbers than what i quoted. Just back of numbers calculation based on what I got from a bit of Googling. I skipped MLU costs because I had no clue how much that would be. You're welcome to add new numbers to it.brar_w wrote:
Although you are on the right track but you need to add a few things into your analysis:
- Actual Sukhoi operating cost. I think it should be closer to the F-15E given its size therefore closed to 30K then to 20K.
- Mission availability Rates: How much availability you have - fleet wide, ultimately determines your fleet size requirement. A 60% availability fighter would have to be procured in greater numbers than an 80% availability fighter etc Rafale should have a MA rate in the EF, Gripen and advanced F-16 category which is 80+% or near about in peacetime while closer to 90+% in wartime. I did the workup on F-15E and F-16 Mission availability rates a few months ago on one of the threads here (in addition to that of the C-17 and C-130) so i'll try to dig some info. Rafale should be slightly ahead given its a younger project with more technology.
- Engines. I think in case of the rafale, your two engines are good enough for the fleet life of 6000 hours. Do the MKI's need an engine change or serious work (down time) before its airframe life expires
- Logistical footprint: Generally your NATO birds are designed around strict logistical requirements given the expeditionary warfare, so you have to figure out how any Man hours does it take to do your basic tech work etc Ultimately, how much do you have to spend per hour outside of the fighter to generate a fixed number of training sorties per year.
Now to the 6000 hour comparison (to bring them at par i suppose): Its a big assumption in favor of the Sukhoi. The Rafale lasts you 2000 hours more, that translates to roughly a decade based on a 200 hr usage. Thats quite a significant advantage given that you'd need to account for that with a larger sukhoi fleet to make up for the last 10 years. Given how long replacement cycles can take to clear the government red tape an added "decade" of prep time definitely helps. Heck SOKO went in and bought the F-15K with a 16,000 hour airframe
As for the hours - if you look at the Ajai Shukla article on Sukhoi overhaul, it appears that the Sukhois haven't even flown 1000 hours in 10 years. That is 100 hours per year - I don't know if it is too much or too less.
Secondly and the most important, is that to compute the lifecycle cost, you need to know the lifetime. I think for a 4th gen aircraft to survive in 5th-gen aircraft world that would in 2030+ would be very difficult. So - I'd say that the active lifetime would be 20 years.
Those who say that Rafale is for PAF and not PLAAF miss an important consideration: We don't know or have control over what PRC will supply to TSP ten-fifteen years from now. To expect that the PAF will keep flying JF-17 or F-16 Blk52 for next 20 years without acquiring new aircraft and using that assumption in a fluid geopolitical scene to buy a white elephant appears imprudent.
