The Case for Propellers: Why the C-130 Hercules Shuns Jet Engines
Story by Nancy Maffia • 18h

Have you ever wondered why the C-130 Hercules, the versatile military transport aircraft that has been a workhorse for the U.S. Air Force since the 1950s, uses old-school propellers instead of modern jet engines?

It may seem odd, considering most military planes these days are powered by jets. But there are actually several very good reasons why propellers are the ideal choice for the C-130’s unique missions and roles.

Propellers Provide Unmatched STOL Capability
 
The key factor driving the use of propellers on the C-130 is the unmatched short takeoff and landing (STOL) capability they provide.

Propellers generate superior lift and thrust at low airspeeds compared to jet engines
This allows “Hercs” to operate from short, unpaved, roughly prepared airfields that jets simply cannot use
The C-130’s beefy Allison T56 turboprop engines (ref) and large four-blade propellers enable it to lift off from dirt and gravel runways as short as 3,000 feet – impossible for a jet-powered transport

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

Speaking of dirt and gravel runways, propellers mean no jet engines ingesting FOD.

Millions now living should have died. Anti-Covid-Vaxxer ghouls hardest hit.

  • I was a "conspiracy theorist". Now I'm just right.

Yep. Throw a rock into a prop and it might get pinged off somewhere. Chuck it into a jet engine intake, and you can get an expensive mess real fast.

Seventeen Techniques for Truth Suppression

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.

The A-10 is designed to land on rudimentary makeshift runways, but its engines are mounted high (unlike the Russian Su-25, BTW).
