Does the world's currently longest range helicopter flt to some of the world's most remote place like Kerguelen Islands?

Sun Mar 12, 2017 8:22 am

Now it take a week to reach the islands by ship but the island have a helipad in it. Is there any helicopters with enough range to carry payload and fly in to the islands from Reunion/South Africa? How about with stops at Prince Edward Islands and/or Crozet Islands?

Nope. It's a 3400 km flight to the nearest point of land in still air conditions. That means a round-trip of about 7000 km at the very least. Even if you hop across all the islands, you will still face a 1800 km flight on the longest leg. The V-22 Osprey probably has the longest legs of all helicopters, and even it will have problems doing a flight that long.

Basically what they do, the helipad is for the AS350 brining supplies in from ships. There are a few runways down there the longest is around 1500 m, just not on that island.

Kergulen, that's pretty remote.



Woodreau what ship is that ?

If you know maybe you can explain, are the port and starboard aircraft elevators always 'hanging out' over the sides or can they be brought inboard somehow ?

That is the Wasp Class Amphibious Assault Ship USS Bonhomme Richard (LHB-6). https://en.wikipedia.org/wiki/USS_Bonho ... ard_(LHD-6). A base/staging craft for amphious assalt used by a Marine Expeditionary Unit (around 2000 troops), combining troop ship, headquarters ship, helicopter/VTOL carrier and landing craft carrier. The landing craft dock through a large door in the aft quarter as seen in the picture of her sister USS Essex below.

Man, those things are cool...

I was surprised to read that the elevators can indeed be folded in, for example to transit the Panama Canal. Learn something new every day!

That is actually USS America (LHA-6) as opposed to USS Bonhomme Richard (LHD-6)

But you wouldn't be the first one fooled. The Iranians were just as confused when USS Belleau Wood (LHA-3) transited the strait of Hormuz and sailed into the NAG.

Then the next day the Iranians were perplexed when USS Kearsarge (LHD-3) sailed northbound through the strait of Hormuz.

There was lots of screaming on Intel chatter listening to the Iranians accuse each other over who lost track of belleau wood allow it to slip southbound undetected and have it reappear transiting northbound again the next day.

Yes the elevators can be folded to transit the Panama Canal but it's not something that can be done on a whim. It's a major evolution (very rare) to fold the elevator pierside just before it transits through the canal. Then on the other side services have to be arranged to unfold the elevator and put it back in the serviceable position.

THe major difference between bonhomme Richard and America is that America is a pure sea control ship (aircraft only) and does not have a well deck to accommodate landing craft (conventional or otherwise)

The normal position for the elevator at sea is in the UP position. The down position is temporary just to move aircraft / stores / vehicles into the hangar bay and then back up as soon as it's no longer needed in the down position. With the elevator in the down position there are maneuvering limitations imposed on the ship. To prevent dragging the elevator in the water (which would probably cause some damage to the elevator)


But to support a remote island solely with helicopters it's something that this class of ship can do. Although a kaiser class T-AO oiler/stores ship can do just as well

But it's challenging integrating all aspects of the ship, i.e. Conducting an heloborne insertion while simultaneously conducting a waterborne insertion and controlling the landing craft waves. Lots of maneuvering to position the ship in a position to launch landing craft which drives the air boss nuts because he wants the ship on somewhat predictable course for winds to operate aircraft which is normally not conducive to operating landing craft.

How dare they have the same hull number on two ships that look so similar?!? :D
