This further expands Indonesia’s procurement from Turkey, including the Khan/Bora tactical ballistic missile and the Hisar-O and Siper air defence systems. In response, Indonesia’s procurement agenda emphasises diversifying suppliers and technological transfer to support Indonesia’s national defence industries and reduce dependence on arms imports. Furthermore, heightened competition between the US and China risks conflict in the South China Sea that would affect Indonesia’s airspace and sea lanes. It is in this context, diversification of defence suppliers makes strategic sense. Unless carefully allocated, procurement risks outpace Indonesia’s ability to sustain and integrate its growing arsenal.
