I want to know the answer to the following question:
Since when has Iran developed its domestic military infrastructure?
All the background I'm provided with is that "Since the 1979 Revolution, to overcome foreign embargoes, Iran has developed its own military industry, produced its own tanks, armored personnel carriers, guided missiles, submarines, military vessels, guided missile destroyer, radar systems, helicopters and fighter planes.". Is that enough to answer the question?
Answer: yes
