Talk Outline

The first part of this talk will explore why the Argentine Air Force (AAF) decided to buy an interceptor plane to replace its old fighter planes and fighter bombers, why the Mirage III was selected and how the AAF sought to complement it with a fighter-bomber plane like the Mirage 5 IAI “Dagger”. The most important characteristics of the Dagger will be discussed, along with the number of planes purchased, the date of incorporation into the Argentine Air Force of the different batches of Dagger, its different deployment bases, and the number of squadrons.

The second part of this talk will deal with the performance of the Dagger in the South Atlantic conflict, the bases of operations in the Argentine Patagonia, the configuration of weapons used in the aircraft, the combat tactics used, description of an attack and a summary of achievements and losses.


This virtual lecture will be held on the Museum’s Crowdcast Channel on Thursday 7 April at 6PM.
