This was in my mind also, it seems like a very dangerous thing to launch whilst flying inverted, especially as the motor ignites after separation.

While pulling severe negative g?
What were the circumstances?
Would you be willing to compromise the performance of missile and or aircraft for it?

As this is on the carrier thread, thought that a snippet here might be useful, for a broader than carrier airwing discussion:

This news also comes as the U.S. Air Force seeks funding from Congress to order eight Boeing F-15EX fighters, part of a long-term plan to acquire at least 144. The original F-15E boasts a ferry range of 2,085 nm with conformal fuel tanks and wing-mounted tanks.

Well for Israel, it has become a burning issue. Netanyahu has done a lot of pallying up with Putin, but would all that transfer over to a "Gantz gvmnt"? The strike route to Iran has always been through Syria, which now potentially could be "switched off" through the wider Russian presence (Saudis might offer a more direct route, under the current circumstances. But this would lack the benefits of contour flying on approach).

Howabout for the RAF? Aside from carrier aviation the F35 procurement was presented as bringing RAF back to the alpha strike game. Conformals for Typhoons have not got much priority and perhaps in the upcoming fighter mix it will become even less so - primarily acting as quarterbacks to stealthier F-35s (finding the targets whereas the tiffies loaded to the hilt with long-ranged Meteors and lobbing them at designated targets from distance). But unhindered use of "air" requires also SEAD/ DEAD, very much an alpha strike priority. That's where the extra fuel would come in handy - but we only have Bs and will any of this apply? Or will it become a driver for the hotly debated mixed As and Bs fleet?

The incident was well publicised. The only point I was making was that it’s sometime necessary to have a plan B. There might be a situation where a missile from the bay will need to be used WVR and in a dog fight situation.

Alpha strike is really a US navy term. The RAF have been looking for a low observable aircraft capable of undertaking the interdictor strike role really since it first got the chance to fly the f117 when it was still a black program. The ability to use a 2000lb weapon in such a role or even a return to nuclear version is probably back in consideration for the first time since the Cold War.

For any tactical fighter f35 has long range for its size however no pilot has even complained about having too much fuel. F35 or any tactical fighter can be as stealthy as it likes but a a330 is not. That simply means the distance is can travel or the time it can persist from any tanker becomes a limiting factor in any peer/near peer conflict. This is bore out by the fact that any of the FCAS models doing the rounds are larger than f35. The RAF and indeed the UK will only likely acquire f35a if a production contract is not forthcoming for “Tempest”.

SEAD is no longer just the responsibility of a striking aircraft or a least it shouldn’t be. It’s the responsibility of all the services mainly due to types of weapons now available. Task force Normandy was perhaps the first modern example of that. Going fwd you take a small craft a mile of a coast with half a dozen spear 3 missile or a infiltrating army vehicles with similar are now capable of degrading missile or radar sites add to that long range mlrs artillery systems and pressure to solely rely on strike aircraft in this area is reduced.

There might be such a situation. I’m not saying that there couldn’t be.
What I’m trying to get at is: would you be willing to inhibit the performance of your missile or aircraft for an outlier situation? How outlier does the situation need to get before you can discount it?
If you need dogfight missiles more often, shouldn’t you bring more? That would bring other problems, of course, in terms of drag, stealth and safety.

Not to ignore SW1's excellent post, but surely the RAF's huge investment in air to air refueling makes their need for drop tanks a lower priority than the Navy's?

For the RAF the issue is how far they can go after topping up from a Voyager. They may want the F-35B to have the same range as the Tornado had with its large under wing tanks. For the FAA it is probably how far can they get form the Carrier as well as the duration of an CAP mission.

I can see ferry tanks being developed for the F-35, with combat types following as a result of operational experience with the plane. A request from the UK backed by the USMC might be a strong enough argument one its own to get work started to develop such items, and one you have drop tanks you can move towards a buddy system fairly rapidly as well. Will this happen soon, probably not unless the Israelis go it alone, but possibly within the next decade.

Yes, and the borrowing of it into UK usage was remarkable... but so were the monies being requested (for which just one rationale - carrier air - would not have "flown").

Absolutely

Agreed. But as someone said upthread: It's good to have a plan B
- especially if it is other people paying for the development & testing

US Army is into that game and have set their "parameter" or rather goal at 500 km... beyond that air (cfr. ownership of cruise missiles, which are also 'air'. Russia - with INF now gone - is interestingly working on a cruise mutation of Iskander as it makes the missiles more difficult to counter than the ballistic ones)

Sure, but in the UK (with UK budgets) having same/ similar capabilities in different services soon runs out of road - not enough money... as we hear here, often

Yes, letting one of Britain's greatest industries whither on the vine is such a good idea.

Huh? I wasn't actually suggesting the F-35B's only carry drop tanks when they're on a carrier. Just that the land use of tanks didn't have much of a case, while the RN has a strong one.

LRPF range is now being looked at for 800km+ which is apparently a fairly straightforward thing. Add in MLRS launched SDB1 to cover the 70-140km gap (if its procured) then ATACM and LRPF pushing out from there and the US will be spoilt for choice.

I think the main use initially for tanks would be for a little extra cover on long range ferry flights, even adding 100 miles extra range makes it a whole lot safer for diverts. For the RN the ability to self deploy out to a carrier or reduce reliance on Voyager could be useful. But its a little ironic that when you really want the extra range, on the first day of war when you're trying to stay out of enemy range whilst you degrade them, the tanks wouldn't be that useful for the UK. With the range of the ordnance that we've currently got or are planning to get at present the tanks won't be that much use as you'd need to be comparatively close in for weapons launch, carrying the tanks would lose the stealth advantage. If we'd integrated Storm Shadow or perhaps when FCASW arrives they might make more sense. Wouldn't harm to be able to keep a CAP aloft for an hour longer though.

Not yet but its under development, the gist is that the 500km was an artificial range limitation.
ArmChairCivvy wrote:- are they not planned to be drop-able?
Only in an emergency. External tanks are not a consumable anymore, and haven't been for a long time. If you did drop them you'd need to lose the pylon as well, and in an F-35 that still wouldn't make you stealthy as the attachment points would still be uncovered.

Agree, but once you fire a wingtip ASRAAM, the attachment points fro which were carried over from the previous generation missile and the same happens... though they would be smaller, sure

You're severely underselling the advantages of drop tanks to the RN. Ask the Israeli's :D

A fairly strong argument can be made for underwing tanks to be essential to the FAA/RN especially as we have no carrier based airborne refuelling capability planned. The idea suggest somewhere above for conformal tanks like that on the Buccaneer would be an interesting option but I think we should watch what the Israelis do very carefully with one hand on our cheque book.

I think I'd be more concerned about getting what we've already got working to its capacity and fully supporting it rather than spending it on things that are nice to have.

Land or sea, it'll be using tankers anyway.

Kinda difficult to fit a voyager onboard.

The case for tanks ought to be huge, the Range of an F35 is not enough to keep the carriers safe when striking a peer opponent.

Probs, but the only option might be the V22, which is a very expensive way to deliver not much fuel.

Preserves stealth and with a potential increase of up to around 40% in range/flight duration, enabling both aircraft and carrier to operate in "safer" conditions. Cheap at the price. :mrgreen:
