let me make it clear.
We got 8 JFT from China between 2007-08
now let me make a picture of 42 JFT manufactured at PAC
PAF starts JF-17 Thunder production
Updated at: 1130 PST, Tuesday, June 30, 2009
KAMRA: Pakistan Air Force (PAF) has started assembling of the first Pakistani-built JF-17 Thunder combat aircraft.
than we saw first squarden by feb 2010.of 14 JFT.
Pakistan-China jointly developed JF-17 Thunder multirole fighter airplane is formally inducted in the Pakistan Air Force (PAF). Number 26 squadron is established in Kamra in which 14 airplanes are initially inducted.
if someone remember the 2nd squarden was ready by feb 2011 bt official re equiping ceremony was held on april 2011.
2nd squarden was made ready by april 2011 and total of 30-32 Aircraft were in service.
As of dubai airshow 38 aircraft are in service(nov 2011) and now this is jan end 2011.at most the production of JFT 1 will stop by 2012 Feb
now count from 30 june 2009 to feb 2012.
so in 31 months we have successfully manufactured 42 JFT.
SO it took us 2.5 years to manufacture 42 JFT.
which equals to 1.35 JFT per month..
now we have from june 2012 to 2015 dec time for Block III.
42 months and 100 aircraft target
if we go by old 1.35 JFT target per month than we can manufacture 60 JFT in 42 months
bt if we increase our speed to 2 JFT per month than we can reach our target by 2015 end.
So it took us 2.5 years(31 months) to manufacture 42 JFT
and if we manufacture 2 JFT per month than we can reach our 100 JFT target with little up and down in time.
