Lockheed Fowler Flaps

I was wondering if anybody knows the reason why they decided to use the Lockheed Fowler flap system on the C130. My best guess is that they were trying to increase lift and decrease stall speeds for airdrops, but I'm wondering if there is a more specific reason. Any input appreciated -D.T.

Fowler flaps give you the most lift because they extend back as well as down. They increase in wing area as well as reshaping the wing. C-130's were designed for short field work as well as air drop. I can't say for sure but I'll wager the prop blast blowing over the wings and flaps is kind of like boundry layer control (blowing bleed air over the wings and flaps) like the F-4 Phantoms had to decrease stall speeds. Boundry layer control was only active when the flaps were down. The principle is like having a man made head wind.
