During Marcos Era Philippines is capable of developing its own missile, called project Bong-Bong1 and Bong-Bong 2.
Based on the results of the tests conducted, the optimum preheat sequence time was found to be 20 seconds.
The fuse detonation performance was 100% for all the dynamic tests of the development phase. All the problems and difficulties previously encountered during the experimental phase have been eliminated.
With regards the to the establishment of firing table for the weapon system. Since December 1972, a series of 37 dynamic tests were conducted on the 180MM rocket.
All the test were performed at Caballo Island except for four firings which were conducted in Fort Magsaysay. Different versions or configurations with fixed fins and the PATO (Pressure Assisted Take off) Type.
