HAL has targetted FY 2014-15 for delivering the last Su-30MKI. Rate of production is reported to be 13 aircraft per annum [2], which would mean that atleast 20-25 aircraft have already been produced by HAL by the current financial year. However only SB101/2/3 have been sighted so far.
Unless someone has some more serial numbers to add then the number stands at 55
(please note that the remarks are for individual aircraft as the information has not come across as shown on the original)
