The current BK 117 aircraft of C Flight were originally inherited from the Apartheid-era "homelands", the Ciskei having acquired 3 in 1983, Venda 2 in 1985, Transkei 2 in 1986 and Bophuthatswana 2 in 1987, making a total of 10 with an extra delivered from Brazil. Two of the aircraft have already been mothballed at AFB Bloemspruit. Four remain in service with 15 Squadron. C Flight's conversion to AgustaWestland AW109 helicopters has been postponed due to delays in developing emergency flotation equipment for the type, thus precluding its use in a maritime environment.
