Angola getting 12, not 18 Su-30 fighters

The Angolan Air Force will receive 12 ex-Indian Su-30 fighter jets from Rosoboronexport and not 18 as was previously reported, with deliveries scheduled to take place from next year.
In October last year it was reported that Angola had purchased 18 former Indian Air Force Su-30Ks. The Su-30s Angola will reportedly receive were offered to a number of other countries, including Belarus, Ethiopia, Vietnam and Sudan. Early last year, Russia was in discussions with Ethiopia to procure the aircraft, as Ethiopia already operates the Su-27, but this seems to have fallen through.
The Indian Air Force has ordered more than 200 Su-30MKIs in a number of batches. The early models delivered were basic aircraft without features like canards and thrust vector controls, and it is these 18 early model aircraft (ten Su-30MK and eight Su-30K fighters delivered between May 1997 and December 1999) that were returned to Russia and replaced with more advanced Su-30MKIs.
India had intended to upgrade these early aircraft but instead used them as part-exchange for new aircraft. They were retired in 2006 and sent to Repair Plant in Belarus in 2011. They remain still there.
The remaining six of the 18 ex-Indian Flankers will be sold to another country with a firm contract for them to be signed soon.
The Angolan Air Force currently flies around half a dozen Su-27s, out of 18 originally delivered. It also has other Sukhoi aircraft in its inventory, the Su-22 and Su-24.
