It depends on aircraft type and mission. A Hawk on a training mission and a Hornet on a live scramble will have subtly different limits.

I guess what you're after are temperature limits. From what I remember the lower limit is -35C ambient (might be -30C) with a wind chill limit of -40 I think. Basically bloody cold and a CO can authorise lower if required for operational reasons. CRFI or JBI limits are also key but not really relevant to this conversation. Unless you buy F35B I guess then friction doesn’t matter. That is a joke by the way.

What I meant to add to my previous post was a point about requirements.

Several years ago the Canadian government selected F35. You don’t accidentally choose F35 if what you wanted was a conventional fighter. The requirement must have been for 5th gen characteristics otherwise F35 would not have been selected.

So, assuming the requirement hasn’t changed, how can the answer be any different this time around? Super Hornet and Gripen NG may claim next gen capabilities but I don’t know if they are on a par with F35.

Anyway, just hot air from me really because I don’t know the answer and it doesn’t affect me either way. Although as a Canadian citizen I am, of course, outraged by the flawed and protracted procurement process of my (joint) adopted land.

Thanks for that.

Reread it. Multiple times. And I think I see my error. You're saying the jets as designed (with zero input of Canadian arctic requirements) nevertheless meet those arctic requirements. That may be true but I find that highly unlikely. I believe it's more likely that the Canadian government hasn't even really considered the Canadian arctic requirements. I believe it's more likely this was a political decision much more than a requirements driven decision. The fact that Canada is buying a stealth aircraft specifically designed for first-day-of-war operations penetrating an area defended by an integrated air defense system when Canada has zero plans to do such a thing, and zero plans to buy all the other military infrastructure to engage in such operations makes me believe this was NOT a requirements driven procurement decision.

F-35C can refuel from Canada's CC-150T and CC-130 tankers, which F-35A cannot unless Canada wants to be raped by LM to pay for a probe-equipped F-35A and no doubt the associated R&D + OT&E costs....

F-35C also carries more fuel than the -A model - and the tailhook would be quite useful if landing on some contaminated short RW somewhere north of Buttfuk-middle-of-nowhere-Saskatchewan?

True, but it's also heavier and draggier. Don't have the figures to hand, but IIRC the A has the greater range/endurance of the three variants.

The A has a tailhook for emergencies - https://theaviationist.com/2016/05/2...t-edwards-afb/ , or the Canadians could opt for the braking parachute fitted for the Norwegians.

You're quite correct on the aerial refuelling issue though - no easy way to square that circle for Canada without opting for the C.

To be fair, that could be said for all of the F-35 customers save the US, UK and maybe one or two others.

Agree on the single-twin-engine debate. If a single-engine Gripen or F-16/F-35 is good enough for flying over the high-north of Sweden or Norway, the I dare say it is good enough for Canada also.

F-35A (along with other USAF fighters like F-15, F-16, F-117, F-22) have tail hooks for that very reason (indeed even Typhoon has a tail hook). They just aren't rated for the loads imposed by an arrested carrier landing.

One other thing. For BEagles’ benefit. Aside from the fact that, as already mentioned, every jet I can think of has a tail hook nowadays. Any jet landing in your ‘middle of nowhere’ might be lucky to find a runway with a cable in the first place. And there aren’t many asphalt runways in the middle of nowhere anyway.

I understand your point about drogue refuelling but I still don’t think anyone would buy the F35C if they did not plan to put it on a carrier. The A model, even unrefuelled, has pretty good range. Add external fuel tanks (fine for a Q scramble) and it’ll be even better.
The NORAD tasking could easily justify the use of a USAF tanker and anywhere else they can rely on the US anyway. Or maybe buy some new tankers.

Again, this is only semi uninformed ramblings not scientific fact so please take it at face value.

The F-35 does not come with the option of external fuel tanks, though test pilot Billie Flynn (a Canadian himself suitably enough) doesn't seem to think it will be a problem.

IIRC the wing pylons were originally planned to be wet, but the piping was removed as part of the weight saving program.

I believe the IAF F-35s have the piping installed and that Cyclone have a contract to provide 480g underwing tanks and Elbit to provide conformal fuselage tanks.

Surely there's a considerable difference between a tailhook which will allow an approach end engagement and the smaller version which will allow a slow end engagement in the event of brake failure etc...?

There are plenty of stories about 'cold/hot' weather testing of an F-35B in the CLIMATIC Chamber at Eglin AFB with LM Test Pilot Billie Flynn. Also the three variants underwent mission testing at Eielson AFB Alaska at beginning of year along with Brake Chute testing on their icy runways.

Does it say somewhere that it can’t handle an approach end engagement? There have been plenty of approach end engagements in various jets with a ‘USAF-style’ hook. Even did a few myself, and it wasn’t a problem.

Latest is Dassault won’t be competing with the Rafale due to the difficulty in incorporating the interoperability required by the contract terms.

"The JSF Integrated Test Force here conducted the first set of tests for the F-35A's tailhook. F-35s have landed using a tailhook before [2010], but not at the speeds and weights being tested now....

Indeed there is. The tailhooks on USAF aircraft are essentially single-use devices meant for emergency use only. Once deployed they cannot be stowed (in flight) and once used for an arrested engagement they need to be removed and replaced before the next flight.

Not true. I was General Dynamic structures engineer for F-16 arresting hook engagement tests at Edwards AFB in 1979. We did approximately 95 engagements at various weights, speeds, and offset distance with no hook change. The hooks are also used to restrain the airplane during ground engine runs. The hook is fully qualified for full airplane lifetime of emergency and engine run use. The hooks are not deployed in flight. Flight manual procedure is to land, lower the nose gear to the ground, then deploy the hook. Hook engagement with nose gear off the ground can slam the nose down hard enough to exceed the nose gear limit load.

The big difference in Navy carrier hook and Air Force emergency hook design strength is due to the difference in cable run out, 200 - 250 ft for carrier, 1000 ft for land based emergency arrestment.

Why would a stealthy aircraft want huge external tanks? The only reason is for a ferry, but if you are AAR capable the justification weakens. How much gas does it take to lift 960g to ferry altitude? More than you might think... How much additional drag do large tanks add during a ferry (even 'coke bottle' tanks)? Quite a lot ... How much additional cost, complexity and weight does installing wet pylons & buying the tanks incur? Definitely some... How much additional range does 2 x 480g tanks give you? Not very much at all! Are external tanks worthwhile? Most people would say, Nope...

There are a lot of assumptions about variables in that post. I think I would like the option to choose if a particular profile worked better with external tanks. I might only have AAR close to home, so I might launch with empty tanks and I might want to fuel them up at the start of the cruise, for example.

Seriously? Most missions flown will not require stealth. And in most scenarios flown, longer legs or increased loiter capability will be a force multiplier. I would like the flexibility. Tanks off for first strike missions, and then tanks mounted for everything else once air superiority is established and stealth is no longer needed. If the need arises during the mission, tanks can always be jettisoned (even though some part of the tank pylon will remain on the wing, stealth to some degree will be re-established).

Are you, or were you ever a, FJ pilot?

I would love to watch you try and convince every FJ pilot that ever lived that they would have been better off without drop tanks.

I think we could all give you numbers from previous aircraft types to convince you otherwise. I’m pretty sure that, if F35 were to ever be fitted with drop tanks, it would follow a similar pattern.

F16 Guy and UD, I agree with your points about stealth vs DTs.

johnwill,

That has changed at some point between the time when you worked it and now. For as long as I have been flying the F-16, in case you plan on an arrested landing or in case of some electrical failures, the -1 and -1 Checklist states that the hook is to be lowered before landing. In case of some electrical issues it even states that the pilot is to lower the hook early, to avoid the possibility of loosing that capability due to later on loss of DC power (partial electrical failures with loss of some/all of the battery buses, which might also render the wheel brakes unserviceable).

US, Canada talks underway to decide if the F-35 will be pulled from Canada’s fighter competition

VICTORIA, British Columbia — The U.S. is threatening to pull the F-35 from Canada’s fighter jet competition if the ally to the north doesn’t change requirements for the winning bidder to stipulate specific industrial benefits for domestic firms. The U.S. government is arguing that since Canada is a partner in the F-35 program it cannot request guaranteed industrial benefits for its companies.......

The Canadian government plans to purchase 88 new jets to replace its aging CF-18 fighter aircraft fleet. Canada will require that a robust package of guaranteed industrial benefits or offsets be provided by the winning bidder, government officials have said. But the U.S. government has objected to that, as Canada is still a partner in the F-35 program, which does not guarantee participating nations a set number of contracts. Work on the F-35 program is based on best value and price.

U.S. Navy Vice Adm. Mathias Winter, program executive officer for the Joint Strike Fighter, wrote Canadian procurement officials Dec. 18, 2018, pointing out that the F-35 agreement prohibits partners from imposing requirements for industrial benefits. “We cannot participate in an offer of the F-35 weapon system where requirements do not align with the F-35 Partnership," he noted in his letter.......

The letter has prompted ongoing discussions between Canadian and U.S. procurement officials in an effort to work out some kind of solution, multiple industry and government sources told Defense News. But the Canadian government will also respect any decision by the U.S. to not bid the F-35 if an agreement can’t be reached, sources added.......

TBH I doubt the US cares WHAT the Canadians buy - sure it would be good for LM and everyone in the F-35 programme to sell a few more but for the USA it doesn't matter as they will just buy more F-18's instead

In factt here's probably a significant number of US military who would like to see the F-18 programme continued as long as possible - it gives them an alternative, it's lower cost and it keeps the pressure on LM

I will admit that I haven’t been keeping up to date on the RCAF fighter issue and I am too lazy to read back through the thread. However, I believe I am right in saying that, due to a prior dispute, Boeing are currently not planning to enter the process.

I have talked previously about the Canadian obsession with twin engined jets. As it stands, the only twin engined jet expected to enter the process is Typhoon.

Airbus pulls out of Canada's fighter jet competition

One of the companies in the race to replace Canada's aging fleet of CF-18 jet fighters has dropped out of the competition.

Airbus Defence and Space, which was pitching the Eurofighter Typhoon, notified the Liberal government Friday that it was not going to bid. The decision was made after a detailed review of the tender issued by the federal government in mid-July.

The move leaves only three companies in the $19 billion contest: Lockheed Martin Canada with its F-35; Boeing with the Super Hornet; and Saab, which is offering an updated version of its Gripen fighter.

Simon Jacques, president of Airbus Defence and Space Canada, made a point of saying the company appreciated the professional dealings it had with defence and procurement officials. “Airbus Defence and Space is proud of our longstanding partnership with the Government of Canada, and of serving our fifth home country's aerospace priorities for over three decades," Jacques said in a statement. "Together we continue in our focus of supporting the men and women of the Canadian Armed Forces, growing skilled aerospace jobs across the country and spurring innovation in the Canadian aerospace sector."

In a statement, Public Services and Procurement Minister Carla Qualtrough said she accepted Airbus's decision. “We understand that participation in this competition represents a significant commitment for suppliers, and we respect this business decision," she said. "We would like to thank the U.K. Government and Airbus Defence and Space for their participation and thoughtful feedback during this process."

Airbus decided to withdraw after looking at the NORAD intelligence security requirements and the cost it imposes on companies outside of North America. It also said it was convinced that the industrial benefits regime, as written in the tender, "does not sufficiently value the binding commitments the Typhoon Canada package was willing to make.".........

One defence expert said few people who have been following the file are surprised by the decision. Dave Perry, a military procurement specialist at the Canadian Global Affairs Institute, said that at times Airbus appeared to be "the least enthusiastic of the remaining four" bidders. “I do have the sense they had reservations," he said.

The company's reference in its departure statement to NORAD security issues is significant, he said.

Saab is now the only European bidder among the competitors. Sweden, where Saab is based, does not have a preferred intelligence-sharing arrangement with Canada and the U.S. If Britain, which backed the Eurofighter bid, believes it cannot meet the stringent NORAD intelligence-sharing measures without significant cost, Perry wonders what that does to Saab's bid.

"It'll be interesting to see if they can put forward a proposal that the Canadian government thinks is workable," Perry said.......
