HUD Gearing? At least some are interested
As part of the QWI syllabus way up north an afternoon was spent in the hangar going through the harmonisation procedure. So with nose jacked up, inclometers in place, board positioned in front and LRUs moved to allow telescopes to be fitted, it was particularly gratifying that one of the course was genuinely interested in the bombs short/long implications of a bad set up. The others thought it would be much more fun to take turns being propelled roundon the pallet forks “surf style”. I thanked them for their time……

The reheat system is taken from the Adour Mk811, used in the Jaguar International variant,
We've all seen the how-low-can-you-get piccys over the years and that competition is definitely over, but what about How High? NOT attempting to compare/compete with the real high flyers (Frightening, Vulcan, PR9 etc etc.) but solely in the context of this thread: On 20 Dec. 1978 I got the ground hogger to 52,500 ft which I'm sure was a record at the time but may well not be now, any later claim? . I reckon you need a high tropopause (which will give you clue to location) and, of course, a clean jet - at v. least pylons only no tanks or stores, not sure about wing tip missiles - long after my time. Actually she was climbing well in full reheat at indicated M1.03ish (with the fuel flow indications back on-scale!) and would surely have kept going for several more kilofeet had I not forgotten to de-select autoslat - AoA went up (I forget the numbers now) out popped the slats, up went the drag - instantly subsonic and one engine went out! Game over but enlivened an otherwise boring high level transit. For two bonus points, from where to where? Guesses welcome, answer next week.
(And just before any smart alec points it out : yes I know it was outside the release to service envelope which, from memory, was about losing the canopy, associated "suck" and pressure breathing - which I don't think we had.)

STANDTO,
You'd need a completely new rear end. If you look at the jet pipe diameters of the Jag and hawk, you'll see that the jag's jet pipe is considerably larger. You need a much greater volume for reheat operations, and has to do with the need for convergant/divergant ducts and the pervert theory (Pressure/volume/temperature) All much too boring for here.
So, to sum up then...........It won't fit.
Sorry. I even started to bore MYSELF then

"the Jag's jet pipe is considerably larger"
Never heard the words 'Jag's jet pipe' and 'larger' in the same sentence before.
Apart from when an ex-Jag mate chum once told me "The hole in my dog's bottom is larger than the hole in a Jag's jet pipe!"

Hardly - more like a human Avo meter! When he tried to install a posh lamp in his house (chosen by his wife), the number of wires in the ceiling didn't quite correspond to the number in the lamp. When he switched it on, he blew the whole circuit!
Now living in Wild West Jockistan - where presumably they still use candles!

Well chaps, there's been a fair bit of nonsense written in this thread about what the jet can and cannot do. Probably best if people post about what they know rather than mindless hearsay and conjecture!
In response to the original request for tales here are a few of the things I was incredibly privileged to do:
Being selected for the Jag at Valley and seeing 2 course mates selected for the GR7 going green with envy (not uncommon amongst the Harrier boys)......
Briefing with a GR4 crew at Waddo, walking out to the jet with said Tonka crew already in with their motors running, pulling all the pins, packing my Jag bag and still taxying before them.......
Firing my 1st Aim 9L within a month of getting CR.......
Having American F16 guys jokingly shake our hands as a gesture of good luck before getting airborne in Turkey in the summer....
Leaving the tanker full of gas (5200kgs), thrashing it over Northern Iraq and 22 minutes later leaving the area down at 2300kgs...
The Down Day virtual Friday parties........
Having the entertainment of Norwich for the evenings and weekends and being allowed to fly the Jag in the daytime - name me a better RAF base.....
Carrying out a 6 ship live LGB drop in Oman with 5 bombs (1 self-des Paveway 2, 4 x Paveway 3s) - each bomb dropped on an FRA and DH'd, then flying home at 100' and staying at that height until the break.....
Being number 4 of a 4 ship bounce in Oman vs 16 odd jets - RAF and Omani Jags and Harriers......
Flying out of Lossie on a crisp winters morning en-route to moon country and OLF to bounce the boys after a night in Elgin......
Doing a fire power demo on Salisbury Plain over three days - 720 rounds of HE strafe and 6 CRV7 pods rippled off in FRAs......
Flying around at low level at night with only a trusty pair of goggles to keep me from stoofing in.....
We still have to force people to go to Valley - name me another FJ type which has no volunteers to leave their jet rather than do a 2nd tour......
No matter what anyone has said about the performance, which is stultifyingly bad, the jet is a great challenge to fly and immense FUN, which is all that matters in the flying game as far as I am concerned.
Don't give a damn about the dissenters and those who do the jet down - The Jag's a blast.

Well said 28 Ft Wingspan. In my time of association with the Jaguar (since 1977) the only people who have ever bad-mouthed it have been those who have never flown it. Never once have I heard anyone that has flown it say it was crap.
