A brief look at the records for 1960 alone shows a fairly impressive line-up
for CAPEX:
SA: 10th Frigate Sqn - SAS Vrystaat, SAS Transvaal, SAS Good Hope
147 Minesweeping Sqn - SAS Mosselbaai, SAS Walvisbaai, SAS
Oosterland
Aircraft included Shackletons, Dakotas and Vampires
Other navies participating included British, United States, French,
Portuguese & Nigerian proving another six ships to those listed above as
well as 2 submarines. Other aircraft included RAF Coastal Command
Shackletons & French Marlin Flying boats. If I'm not mistaken the Marlins
put down on Langebaan lagoon, & the event was actually covered in the
newspapers of the day.
