There is no SA HMDS. What was demonstrator models are all gone. The Marconi people (now BAE) licensed the LED based helmet tracking tech from South Africa, combined with a analog display. This is striker 1 by BAE, HMSS in Typhoon, and Cobra in South African Gripen A/C. The same head tracking stuff is evolved and now is in Striker 2, as I have been observing from afar. Many in south africa claim to have HMD, like ATE, now paramount, but I dont really buy it. It takes 100 Million USD to develop one, and 50 Million to qualify it for an aircraft. Even the one made by Elbit still is not qualified for F35 for the full fleet pilots. This is complicated technology and not for everyone to master. There are few winners in this, and BAE sure is one.
There is no HMD tech in Denel. What has china bought? What is the basis of your claim?
PAF is user of high quality systems. Look at the History, all electron stuff in Falcon, then Mirages, then Mirage upgrade has been top of the line. Then we take avionics from China? The cannot elaborate on the blunder but the decision itself is a blunder. This is called weak link dependency, when the serviceability of your system becomes your weak link, and you have your A/C on the flight line unserviceable because the damn electronics is not good enough for the environmental conditions of PK.
