<p>
The SRDP is envisioned to protect the country's interests from foreign control and promote limited dependence on outside support for our defense requirements. Self-reliance on our country's defense manufacturing capabilities coupled with the full utilization of our own natural resources are its foundations. And with clear instructions and a mandate, the Philippines ventured successfully into many projects which include among others: 
</p>
<ul>
<li>
Project Santa Barbara's Bukang Liwayway and Sumpak, 
</li>
<li>
Projects BongBong 1 and 2, 
</li>
<li>
The Delta Mini Cruiser (produced with a joint venture agreement with Toyota Japan), 
</li>
<li>
The UHF and VHF radios by Vetronix,
</li>
<li>
The manufacture of the M-16A1 rifle under license from Colt Industries.
</l>
</ul>

"We taught and we have learned our lessons well that we should never build our defenses on the shifting sands of mutual defense agreements, and it is time we build it on firmer foundations. For while we have faith in our allies, we should not be completely dependent upon them. For while we believe in their courage and their capability, they also have their own national interest that may sometimes conflict with ours. For in matters of defense the guarantee of friends can be modified to suit their needs and interest, as the history of nations vividly shows."

These words of President Ferdinand E. Marcos laid the foundation of a vigorous attempt to develop a defense system of a self-respecting, independent nature, relying solely on the country's capabilities and resources: The Self-Reliant Defense Posture Program (or SRDP) of the Republic of the Philippines.
