The C-130 is the world’s most prolific cargo hauler and it’s been adapted to do pretty much everything imaginable
with one exception: operating on water. Yet some of the folks at
Lockheed wanted to do just that in the 1960s. Sure, amphibious planes
are a niche, but the already boat-like C-130 seems like a perfect
candidate.
Making the
C-130 into something capable of playing in water involves more than just
modifying an amphibian hull onto the plane’s already rotund fuselage.
And it would certainly look amazing (I am a sucker for float planes, especially huge ones),
but the drag and weight penalties caused by mounting floats on a
Hercules would be damning, greatly impact range and detract from the
C-130’s useful load.
Instead, a
C-130 flying boat would experience a minimal drag penalty induced by its
stepped hull and outrigger floats. In fact, those outrigger floats
could potentially be attached to the C-130’s existing outboard wing
hard-points and loaded with fuel. One could even imagine small boats
being designed to be raised and lowered via modified inboard wing
pylons. This would allow a C-130 amphibian to retain its cavernous cargo
hold while having small boats available to act much like a traditional
patrol ship.
The best
part about the amphibian flying boat concept is that it doesn’t have to
live and operate on water alone, but it can just as easily operate from
land and conventional runways.
The concept
you see at the top of this article was actually a model built for the
Navy to demonstrate the C-130 amphibian concept. It’s described as such:
Although
the romantic idea of taking a flying boat to some far-flung exotic
locale died many decades ago, the flying boat idea has been coming up
lately, but with a futuristic face-lift. Although many of these modern,
fantastical flying boat concepts are laughable, a C-130 amphibian has clear practical uses, without needing any expensive infrastructure improvements.
A C-130
amphibian would probably be the best fire-fighting aircraft of all time,
being able to scoop up thousands of gallons of water on lakes and
waterways while still being able to operate from existing land bases for
retardant drops. Above all else, such a configuration would also allow
these aircraft to utilize the common parts bin and logistical train as
normal C-130s. This would lower operating costs and increase
availability, both factors that has heavily hampered a hodgepodge of
other flying boat fire-bomber concepts over the years.
Even the
U.S. Coast Guard could benefit from such a C-130 configuration. When
used in the search and rescue mission, USCG Hercules can locate
survivors and even toss down supplies to them in some circumstances, but
they can’t rescue anyone. An amphibian configured C-130 could prosecute
the entire search and rescue mission under decent weather and sea
conditions. This was a proven practice in WWII and continued into the
early 1980s with the HU-16 Albatross flying boat. A C-130 Amphibian could extend the USCG’s rescue reach thousands of miles from shore.
There are
many other applications for an amphibious C-130, like disaster relief
and even military missions, and especially those carried out by the
special operations community. In fact, the vast majority of the C-130’s
many missions it has assumed over the better part of a century could be
carried over in a amphibian boat form. Especially “roll on and roll off”
and bolt-on modifications that have become so popular over the last two
decades.
In the end, do we need the C-130 amphibiant? Perhaps not, but it sure would be awesome to have.
