Among the items being exported are ammunition, anti-tank guided missiles, rocket launchers and shoulder-fired surface-to-air missiles.
"Our defence exports have been rising substantially because the arms and ammunition we manufacture meet international standards," Maj Gen Mohammad Farooq, Director General of the Defence Export Promotion Organisation, said.
"We even won a contract in the face of tough competition from developed countries to manufacture parts of Boeing aircraft," Farooq told the Dawn newspaper.
Farooq said the value of arms exports had tripled and this was "very good for Pakistan".
Arms trade was a complex business and it had to be conducted on a government-to- government basis.
Pakistan is answerable to the world community in terms of ensuring that the weapons do not fall into the wrong hands, he said.
Exports to countries in South Asia, Middle East and Africa had "increased significantly", he said.
Though there was a time when the state-run defence industry exported only small arms and ammunition, its range had now diversified and developed countries too are purchasing Pakistan's military hardware, he added.
