Since December 1972, a series of 37 dynamic tests were conducted on the 180 MM rocket. The project, initiated by President Ferdinand Marcos, also involved testing of other weapons and armaments.
On September 1975, four “bongbong” rockets (named after Marcos’ son, obviously) were successfully launched. Asked about why the country was experimenting in making its own ballistic missiles, President Marcos explained:
“The defense of the Philippines cannot be left to alliance with other countries. We must assume that there will be contingencies where even the United States may not be ready to come to our assistance.”
