The Department of Defence declined to comment on Friday on reports that it was finalising the purchase of a luxury VIP jet for President Jacob Zuma.
However, there are suggestions that no such deal is on the cards.
"The [defence] minister [Nosiviwe Mapisa-Naqkula] will engage the media on the projects and programmes [of the SA Defence Force] in a week's time, after a briefing on these," said defence communication head Siphiwe Dlamini.
He declined to comment further.
According to media reports, the jet would cost $150-million (about R1.26-billion) and an extra $80-million (about R672.5-million) to reconfigure.
Also included in the deal was a Global Express 600 costing $28-million (R235-million) for the deputy president, bringing the total bill for VIP transport to $258-million (about R2.17-billion).
Presidential spokesperson Mac Maharaj referred to the defence department queries about the reported deal, which has provoked an outcry from the Democratic Alliance, which says spending R2-billion on an aircraft is wrong, given South Africa's levels of poverty.
"Before you make assumptions, first verify [with the department]. You are assuming they're spending it... There was no such deal on the table," said Maharaj.
He said there was no provision on the budget for such expenditure.
He then declined to comment further.
It is understood that while the defence ministry might have looked at providing a VIP jet for Zuma, no commitment has been made, nor is likely be made to actually purchase one.
