As always, the question is how much do you need that extra range, and should the navy a/c do that mission when it is needed? Kind of depends how you define the I want to see the carriers able to hit Afganistan from the Indian Ocean and a few other places that might be a tad less accessible. Call it the "anywhere in the second country in from the beach" rule. The question is, how often is that second country in more than X nm from the beach. Should we plan our military around a single third-world country? Justify why we need to meet your want. You know, what the people who make these decisions have to do, as opposed to the likes of us who are free to spout our pet theories on Usenet;-) Actually, hitting Afghanistan up at least as far north as Kandahar and maybe up to Kabul from 50-80nm offshore would be possible by unrefueled F-35Bs (assuming they meet their range requirement), and the rest of the country if you tank them. littorals -- you can see claims and studies made for everything from 200nm to 650nm from the coastline, depending on whose ox is being gored -- here's one that discusses this issue, and decides based on historical evidence that 400nm is about right, and that the STOVL JSF is more than adequate for all three services: http://handle.dtic.mil/100.2/ADA331611 I tried to look, but I became too impatient and gave up on the down load. The devil IS in the details, and if you want to discuss them, you've got to know the issues, assumptions and proposed strategy. Note, while you'd expect this to be a USMC paper, it was actually written at ACSC. Still, there were definitely Marines involved in writing it, so take the analysis and conclusions with as large or as small a grain of salt as you think appropriate. Because the ships aren't going away since they need the deck for the E-2 and C-2 anyway. Of course, when (if) the V-22 or some similar VSTOL support a/c enters service, that particular justification need no longer exist. Putting a spinning top on a V-22 sounds scary to me, have to be plum tall to see over those rotors. Might do an EV-22 with a phased array. That was the proposed method; initial idea was to use a triangular radome on top with a three-face phased array. Later there seemed to be some interest in a spine-mounted array like the Erieye, or a ventral folding array. The V-22 has a lower ceiling and no pressurized cabin, although it may be possible to insert a pressurized module into it (kind of like RB-52s had). Or alternatively, everyone will just have to wear oxygen masks. The other possiblity would be to develop a new fuselage with the powerplants etc. the same, kind of like the E-2/C-2 did. As for the COD role: the C-2 does 10,000 pounds over a distance in excess of 1,000 nm. Not according to the C-2A S.A.C. (available on the Naval Historical Center website). Range with a 10,000 lb. load is 961nm, with reserves. The CV-22 can provide VTOL with 8,300lb of cargo for 220 nm. Why on earth would a V-22 COD make a VTO? It will make a STO or full rolling takeoff from shore, a STO from a carrier or LHD/LHA, and only make a VTO from a LPD/LSD/AOE. A C-2 can only land on the carrier and has to tranship loads to a helo for the latter ships (and hope that the helos are in range), while a V-22 can go direct to them. Obviously you aren't going to move as much as fast using CV-22 vs C-2. That remains to be seen. Empty and MTOW weights of the C-2 and MV-22 are in the same league: 33,746/54,354 for the C-2, and 33,140/57,000 (STO)/60,500 (max.) for the MV-22, and the latter is carrying around self-sealing tanks and armor that the former isn't, and doesn't need to maintain the same reserve fuel. The MV-22 currently lacks a pressurized cabin, which might or might not be significant when carrying passengers, depending on the range, weather and cruise altitude. It's cabin is also slightly smaller than the C-2's, which again, may or may not be significant. Let's assume for the moment that the V-22 can handle COD and radar missions. Then you are stuck with the tanker problem and three choices: 1) Use the V-22 as a tanker. r) Odds on bet the V-22 is too slow. Too slow for the escort tanking job, certainly, so that will remain with buddy tankers (or, down the road, a STOVL support jet). I asked Cecil Turner about this a year or two ago, as he'd refueled in his A-4 and AV-8B from various a/c. Based on published stats, a KV-22 should be able to tank strikers at least up to 15,000 feet, which he said was a typical tanking altitude, and maybe 18-20,000 (the latter would probably require a toboggan). As for recovery tankers, if the navy goes all STOVL there will be far less need for them because wave-offs due to fouled decks will become a thing of the past, as will bolters, and the incidence of missed approaches due to low visibility will shrink to almost nothing. A KV-22 will certainly be lower in performance than the current S-3s; the question is how critical is that performance to the mission. 2) Buddy store off a F-35B. r) Yea, that would make buddy storing off F-18s look positively lovely. How much passable gas could you actually get off the deck? Considering that the F-35B is credited with equal or greater range than the F-18E/F on slightly less internal fuel, has only one engine, lots of wet external pylons and no need to hold large landing fuel reserves, I imagine the answer is a comparable amount. 3) Call the Air Force. As the navy has been doing in every one of our recent conflicts. Or the RAF, or the Dutch, or the Italians, French, Australians, Japanese, Germans . . . Guy |
