What type of bombs did bombers use in the Vietnam war?

Since smart bombs were not yet fully developed during the Viet War, the terms "dumb bombs" and "iron bombs" were not generally used. US bombs (called ordnance) were simply referred to as: General Purpose HE (High Explosive), etc. The most common were the 250lb, 500lb, 750lb, 1000lb, and over...plus the daisy cutter. The 500lb and 750lb were by far the most popular bombs to be used by airmen and the most popular requested by men on the ground; but there really was a bomb shortage during the war. WWII and Korean War stocks had been used up. Factories had to manufacture new bombs to keep up with demand.

This was in ADDITION to the US Navy's need for 16" shells (equal to a 2,000 lb bomb) for the battleship USS New Jersey working on the gunline; as well as the 8"and 6" gunned cruisers and 5" gun destroyers. Each one of those USN projectiles was equal to a small bomb. And those also had to be manufactured in American factories.
