Australia helped defeat the North Vietnamese Air Force.
How do you wonder?.....
Back in the Vietnam War, the RAAF's 79 Sqn flying CAC Sabre Mk 32 jets was based in Thailand at Ubon Air Base flying CAP for the base/area and would at times intercept returning USAF F-4 Phantoms and F-105 Thunderchiefs to give them training in the missing art of dissimilar air combat.
They would intercept and using their guns and AIM-9B Sidewinders to practice their skills of CAP and air to air dog fighting.
The training was done to give the USAF aircrews a better way to take on the North Vietnamese MIG -17 fighter.
The MIG-17 was similar to the CAC Sabre jet Mk 32 in size, performance and abilities.
Here we see a short film clip about a USAF F-4 crewman discussing how the Aussies helped save them over North Vietnam.
