Don't eat Benbecula fish
 
A lot of 7 Sqn Rushton sorties were out of Kinloss to the Benbecula range.
For a while we used a device called RAMDI. Radioactive Miss Distance Indicator. A small geiger counter placed in the body of the Rushton which could pass information down the cable to the Canberra crew.
A small radioactive particle was placed in the nose of the Rapier. If it passed close to the Rushton we obtained a readout of distance.
I wonder just how "trace" that particle was if it could be detected at 20ft whistling past at 600kts.

Drift:

There is a story about (Paddy someone, crewman Ldr?) a 33Sqn officer who was so confident that the crewmen were total crap at A to G, that he put his SD hat on the target at the range. Not a scratch, apparently.

Someone will have the details I'm sure.

Paddy someone, crewman Ldr?)
It would be just like him to do that. I believe that after we left the other squadron fired off loads of ammo, then threw the rest in followed by the guns.

Enough thread drift; back to the Cranberries.

Gents, I am staggered, but very happy at this flurry of activity. Usually there are only one or two replies, but this bevvy of stories has had me grinning all evening here. :ok:

Lots to work through here, but a few things spring out and some PMs maybe coming your collective ways as a result. Everyone else, perhaps too many priceless gems in there to call individually, but cheers all for sharing them. A few others though I have to mention:

Halton Brat:

The story you referred to in Air Clues sounds suspiciously like the one the late Les Bywaters of 3 Sqn told me about Flt. Lt. Ron Ledwidge (if I recall his surname correctly). The incident he related was that Ron's B(I).8 indeed had a stuck aileron and matches yours perfectly, down to the nav bailing out after timing the orientation just right. Not easy I would imagine from the prone position in the Can nose cone.

Beagle:

You wrote: "the first target was a Canberra PR9 (some trials thing with an odd-looking nose)." My suspicion is this was almost certainly XH132, the Shorts modified SC.9. This was the only Cran PR.9 with a nose job. Went through several paint schemes over the years - do you happen to remember what it wore for this incident? Pretty cool that it gave a good account of itself. Did the TT.18 actually put up a fight despite being easier? Being from East Anglia (next door to Wyton), hearing about doing QRA intercepts on these Cans is of interest to me. Can you describe how you typically approached them and what action they typically took if they saw you?

Dalek:
You say you were on 85 Sqn in the early 70s- did you ever fly the T.11 or 19 during that period?

ExMudmover:

Are you referring to the runs performed at Goose Green? If so I am assuming you were on GR.3s - again, if so, did you know Jeff Glover by chance?

BBadanov:

Sorry, yes, I grew up reading too many war comics and even in my mind as 32 year old I imagine that banner towing was adventerous! As you are all rapidly pointing out to me it seems it was a little more sedate than that.;)

500N 21st Mar 2012 04:21

Question re the exact location of the Bombing range on the Wash / East Anglia.

I used to spend a fair bit of time on the Wash (bird catching)
and used to sit on the sea wall and watch some of the jets doing
what they did - late 60's and throughout the 70's.

I can't remember exactly where it was so if anyone could remind me,
this would be good.

Also, did any mishaps occur (bird strikes) with the huge flocks of birds / waders that used to fly around their ?

Thanks.

nazca_steve 21st Mar 2012 04:24

Possibly Holbeach Bombing Range:

RAF Holbeach - Wikipedia, the free encyclopedia

I am sure someone will confirm though. The wildlife aspect is mentioned here so seems a good match:

RAF Marham - RAF Holbeach Bombing Range

500N 21st Mar 2012 04:40

Thanks. Holbeach sounds right as that was one of the places we went.


I like the warning at the bottom of the RAF Web page.
Used to find (or see) a fair bit of stuff way out on the Marsh
as that was where we were mainly catching the birds.

Canberra target facilities flying
 
Nazca, drifting a bit from your earlier question regarding target tug and AI training tasks, but possibly of interest to you are some of the other roles that 100 Sqn RAF (aka Tatty Ton) undertook in the early 1980s. Its primary task, at least in terms of programming priority and time spent airborne, was performing practice interceptions (PIs) for the School of Fighter Control at West Drayton. These PIs were mind numbingly dull - 2 Canberras were launched to act as a target and 'fighter' for the trainee FCs. I think we were contracted to provide an hour and a half on task, usually in the upper 30s/low 40s flight levels with a half hour transit each way. Two of these sorties a day was not uncommon. An earlier poster has already bemoaned the appalling air conditioning in the 'berra - we had heated electric socks to try and keep the frostbite at bay. We (well the navs certainly, not sure about the nose gunners) got a good soaking in the descent as the ice inside the cockpit melted. I have said previously that banner towing was dull, but it didnt come close to the boredom of these PI sorties.

A much more interesting task was acting as targets for the Bloodhound SAM sites around the UK. This was our one chance to do some low level flying. A significant part of the sqn was young pilots and navs who had not quite made the fast jet slots through training and needed some flying hours, airmanship and experience before stepping up to fast jets for their second tours. Fat dumb and happy in a large slow jet, with no RWR, we happily tooled around the Bloodhound sites having a bit of fun.

nazca_steve 21st Mar 2012 05:53

Spectre150, this is exactly the kind of stuff I am interested in. Please let me know if I have not sent a PM yet to you. Feel free to drift around topics as much as you want. 100 Sqn is always of interest to me - those filthy stripey things will always have a special place in my childhood memories!

The defrosting ice decent comment is priceless...lack of most mod cons seems blindingly apparent in the Canberra. Perhaps another of its endearing factors to the armchair enthusiast like me, but not to those who lived it!

You say no RWR - I thought most Cans from the Mk.8 onwards had Orange Putter? Oh wait, that was active radar, right? I always get muddled with radar types, bear with me...

BBadanov 21st Mar 2012 07:23

500N "Thanks. Holbeach sounds right as that was one of the places we went."

Mate, it's been a few years but I thought the most southern range and closest to the wash was Wainfleet. Then Holbeach was north, and Donna Nook further north again. I may have these last two ass about.

No doubt QWI extrordinaire, Foldie, will pull his range map out of his hip pocket and correct me! :ugh:

Steve: "You say no RWR - I thought most Cans from the Mk.8 onwards had Orange Putter? Oh wait, that was active radar..."

I never had anything to do with the Canberry in the RAF, but my guess would be that the only one that had an RWR was the PR.9. I stand corrected, but it was probably an ARI 18228 (or some such number?).

GAP
 
One function we had on 7 Sqn which was a lot of fun was providing training for Forward Air Controllers at Templeton Airfield in South Wales. This involved flying what was known as the Templeton GAP (Ground Attack Profile) which was a cloverleaf pattern of airfield attacks usually flown as a battle pair.

As I remember the four legs were: From the North at 250ft 360 knots low level straight in lay down bombing followed by a pull up to 4000ft and a tear drop turn to run in from the West for a dive bomb run bottoming out at 250ft for a low level run out to the east, a low level turn in on an offset to pull up for a tip in dive attack which was repeated with a run from the south.
At this point, the no 2 aircraft would take the lead and we would go round again.
Great fun and usually flown on Thursday and Friday when the Navy didn't need us at Plymouth.
These manoeuvres formed the basis for the attack profiles used during the St Mawgan Air Shows.

Had a look in the log book I have with me and note that we also did a similar profile on the Larkhill ranges.

dalek 21st Mar 2012 07:54

NS
Quite a few T19 sorties. B2 with pointed concreted nose and no tip tanks.
No navaids either other than TACAN.
We tended to use the T19 for PI's and any sortie that required climb above 410. Pressurisation limitations limited ceiling to 470 but with a light aircraft we once took one to 520. We still had a reasonable rate of climb but MCrit and safety speed considerations made us chicken out.
Never heard of a T11

spectre150 21st Mar 2012 08:01

Steve, the period I am talking about (early 1980s) was towards the end of the Canberra's long career. With the demise of 13 Sqn in the recce role around that time that just left one operational mark in the RAF - the PR9 flown by 39 Sqn. 100 Sqn was a targets facilities unit and having no operational role did not require operational role equipment such as RWRs. We did hope that something would be fitted if we ever had to carry out our war role of LOPRO (I think this was covered elsewhere in this thread) although it was generally accepted that without the performance and manoeuverabilty to evade Soviet maritime defenc,s the RWRs of the day would not have provided much more than an warning of imminent disaster!

I have no idea what an Orange Putter is. The B(I)8 was long out of RAF Service by the time I joined the Force (my father was a B(I)8 nav in Germany when I was born). Later marks were not necessarily more 'operational' in the sense that they had more modern equipment (your comment suggests this might be your thinking). The TT18, for example was a re-worked B2 fitted for the Rushton target towing role. The E15 (a modified B15 variant) had the bigger Avon engines whereas the TT18 had the smaller donks fitted to the B2/T4 family. On 100 Sqn in my time we operated a mixed fleet of B2, T4, PR7, E15 and TT18s - the monthly log book summary was always a bit of a chore!

Yes, it was the SC9, probably on the way back to RAE Bedford. It was in raspberry ripple clours, if I recall correctly. I think it ended its days at RAF St Mawgan as I saw it there during a UAS Summer Camp in about 1992 looking rather forlorn in faded hemp and grey. I can't remember whether it was still intact, but the nose section certainly was.

A practice QRA intercept was unlikely to include any evasion - the targets did not normally respond. All the practice was intended for was to exercise the system, so we were usually tasked just to 'intercept, identify and report' - even an exercise engagement with 8 live missiles on board posed a degree of risk. So usually it was just a simple intercept, before closing to loose echelon.

Orange Putter
 
Spectre #94

Orange Putter was a little active radar, of 1950's vintage I guess, to be found in the tails of PR 7 and B15 (and no doubt other operational) Canberras of my time - FEAF 1962-4. It gave a coarse quadrant display of a threat from behind to the nav plotter. I never knowingly saw the display myself. It gave too many spurious warnings so it would have been a worrying nuisance on an operational sortie (you hoped); of course you would only switch it on briefly for fear of actually attracting trouble.

If however you had a high level night exercise with the promise of an interception, it was then useful to time the start of your version of the Lancaster corkscrew. You might never see the Sea Vixen or Javelin concerned (which you could usually by day), but I remember no post-flight crowing about being "splashed" so it presumably worked.

Tinribs 21st Mar 2012 20:16

Canberras and loosing things
 
If the topic is to drift a bit then someone has to mention the Prussian Queen event

You talk about interesting pilot/nav miss communications

A 100 sqn Nav Laurie Davies, later died in a PR9 crash at Wyton, had a favourite trick when airbporne with a new pilot. He would disconnect from RT and pass the cockpit on his way to the nose bombing area waving a large screwdriver. Over the next few minutes important looking electric thingies would be thrown backward into the cockpit area. Laurie would then reappear saying " OK clever dick lets see you cope with that", the bits had of course come aboard in his navbag and were nothing to do with the aircraft being flown. After landing the pilot would then find his flying boot laces had been tied to the rudder pedals

Certainly brightened-up a summer camp at West Raynham for this cadet when, out on a forced-march around the local area, a Canberra appeared from behind a row of trees.

longer ron 21st Mar 2012 21:36

I know what you mean...whilst at Brawdy in the late 70's and while picking up a brand new Triumph Tiger 750 from Llawhaden (sp?) a canberra appeared at extreme low level - contour hugging through the valley...lovely sight !

spectre150 22nd Mar 2012 03:22

rlsbutler - thanks for that info. I am still a little confused - you describe OP as an active radar but also make it sound like an RWR (ie a receiver) when you say 'It gave a coarse quadrant display of a threat'. I could understand if the bombers were fitted with rudimentary RWRs to pick up AI radar equipped fighters (Jav/vixen in your time?) but not an active sensor. Can anyone enlighten me further?

Fareastdriver 22nd Mar 2012 09:39

The Orange Putter they had on the Valiant was a baby radar. It had a small screen in front of the captain that indicated where a trailing aircraft was. Taken out of bombers to stop missiles homing on to it, too long minimum range for tankers, so ditched.

NRU74 22nd Mar 2012 15:23


The Orange Putter they had on the Valiant
I remember we checked it was working by firing a Very cartridge filled with chaff, also when the interceptor reached,I think, one mile the blip on the screen sprouted 'wings'.

Fareastdriver 22nd Mar 2012 20:16

This is what Orange Putter looked like in a Valiant. Item No 10.

nazca_steve 23rd Mar 2012 06:35

From the Indian Air Force web site: The English Electric Canberra in Indian Air Force Service - Anandeep S Pannu [www.bharat-rakshak.com]

This confirms the spurious warnings nature rlsbutler discussed. As others have pointed out, nice idea but had the drawback like any active radar of attracting attention. The site reads:

Orange Putter” – was tail warning radar on the PR.7...Basically “Orange Putter” was radar that projected its beam backward from the Canberra, so if an enemy aircraft attempted to sneak up behind it to shoot it down, the radar could warn the crew about it. Unfortunately it wasn’t always reliable, and often gave spurious warnings. This had the effect of raising blood pressures of the aircrew – and at least one vital photo reconnaissance mission was called off because of spurious “Orange Putter” warnings. These spurious warnings resulted in an erroneous intelligence estimate of an enemy fighter force existing where there was none, during the 1961 Goa operations! Another Canberra sortie had verified that there were in fact no fighters anywhere to be seen!

The other drawback of “Orange Putter” was that it was an active system, i.e. it radiated radar energy. As many a Mosquito night fighter and intruder crew found to their misfortune in WWII, this lead properly equipped enemy fighters to them like moths to a flame.
"

I will see if I can dig this up in the B(I).12 APs I have, but I am sure OP was not just on the PR Cans, but the interdictors as well. May have even been on some of the earlier variants but pulled out later on when realised to be obsolete. Spectre150's comments defininitely imply that this kit was long gone by the final days of the Can.

Whatever the case I feel it was a nice idea at least to give the poor old '40s era Can a chance of picking up someone sneaking up on it. I wonder if for some reason it was not on the 13 Sqn PR.7 that was shot down in Suez, as they were using a rear facing periscope to spot for bandits.

Thanks for this clarification, Beagle, I know the raspberry ripple scheme, indeed it was one of my favourites - too bad she did not stay in this scheme and went plain old hemp/grey. The nose was apparently saved by an Italian collector and ended up out there as far as we know.

Having TACAN at least was an advance over the early B.2s and other variants...off the top of my head I think these may have only have had ADF at the time. With TACAN fitted did you bother with ADF at all or just go with the former nav aid?

Ref the T.11, this was the former version of the T.19, except it has the AI radar in the nose cone and not the concrete version! I believe this was a variant design to train Javelin crews in AI, later on when this was no longer needed the redundant T.11s had the radar removed and became your variant. I asked Options770 in an email if he remembered if the gun sights were still fitted in the 19 or not...do you remember by chance?

BBadanov 24th Mar 2012 06:41

Having TACAN at least was an advance over the early B.2s and other variants...off the top of my head I think these may have only have had ADF at the time.

It was the same-same but different with the B.20. :hmm:

When it was announced in late 1966 that 2SQN would deploy from Butterworth (Malaysia) to Phan Rang (South Vietnam) several mods had to be undertaken. TACAN had to be fitted, as all navigation in SVN to R/Vs was to a TACAN point. UHF was added to the VHF, as UHF was the tacair freq band (choppers and FACs also, of course, had FM). Armour plate was added under the pilot's bangseat and under the nav's prone bombaimer position. Also nitrogen purging was added to the fuel system to prevent tank fires if hit by groundfire.

ADF was retained, and later replaced in an early 1970s navcom upgrade. At that stage, there were many more NDBs in Aust than TACANs and VORs.

The other navaid was Green Satin doppler with a GPI (mk IV I think).

dalek 24th Mar 2012 16:24

I arrived on 85 in 1972. I don't think there were any gunsights by then.

BSweeper 24th Mar 2012 21:40

The T19s that I flew in 1975-78 certainly did not have a gunsight.

However, they were incredibly fuel efficient. On internals (3 main tanks) plus bomb bay tank (no tip or wing tanks; 13,500 lbs total I think), they could get from St Mawgan down to Gibraltar and land with the same fuel as a TT18 with tips (18,000 lbs). They could also cruise climb to well over 52K. IIRC, range descents were about 110nm from TOD.

nazca_steve 24th Mar 2012 22:56

Thanks for confirming it. It is highly likely the gun sights were removed full stop from the T.19 - I will see if I can get hold of the Pilot's Notes for it and see. Makes sense though without the AI radar still fitted.

Also good to know the 19 was so fuel efficient. Does anyone recall what the cruise speed was for say the B.2 and B.6 (as representative of the first and second gen Avons)?

And also...first batch B.20s or the 7,500 RPM ones? Or was it the same on both?

BBadanov 25th Mar 2012 05:30

Same on both: A84-201 to A84-227 "Mk 1" Avon 6500 lb, and A84-228 to A84-248 Mk 109 Avon 7500 lb.

Frankly I can't remember now what 0.74 would give you at altitude (above 40k ft), about 450KTAS I think, maybe a tad less? :confused:

BEagle 25th Mar 2012 07:47

M0.74 / FL 400 ~ FL 500:

ISA-15 = 409 KTAS
ISA = 424 KTAS
ISA+15 = 439 KTAS


(Why does this stupid editing system keep changing upper case to lower case.....:mad:)

pr00ne 25th Mar 2012 10:35

What makes anyone imagine that the T19 ever had gun sights fitted in the first place?
As they were converted from the B2 to the T11 by sticking a Javelin radar in the nose, Javelin navigators for the use of, and then converted to the T19 by taking it out again, where does a gun sight come in?

dalek 25th Mar 2012 11:38

BSweeper is right about the fuel efficiency. Some of our older and dumber (pilot) Flight Commanders could just not understand it.
We once flew a "raid" from Norway requiring an attack on Bawdsey? at 470.
Weather conditions were marginal so the 100 Sqn authoriser insisted on giving his crew a B2 with Tips and Belly 16,800lbs, for max diversion fuel.
Our 85 Sqn crew left in a T19 with 11,000lbs.
We shot straight up to 470. The B2 struggled.
We arrrived back at Trondheim with 800lbs more fuel.
Dumb ba***ard did exactly the same the following day.

rlsbutler 25th Mar 2012 12:49

Fuel "efficiency"
 
BSweeper

Without being picky, may I say your T19 was not “incredibly” fuel efficient but predictably so ?

Compared to your airframe with no operational stores to carry, our B2s and B15s during my time in Singapore never (I think) surrendered the bomb bay to a fuel tank. We always flew high level with tip tanks, presumably because operationally we would have dropped them, and had almost no real range benefit from their extra fuel.

My longest trip was the initial ferry of one of 45 Sqn’s new B15s (with tip tanks) from New Delhi to Tengah. I was supposed to stage through Rangoon. I was a bit of a graphs-anorak and knew what line to track, so by the time we were due to let down for Rangoon we had told FEAF we were keeping going. I did not ask and no one complained. There were no competent air traffic authorities, so we cruise-climbed from the beginning. Those were the days !

BEagle (at #114) will have had a typo – his first line should probably have read ISA-15 = 409 ktas. We in the tropic zone would have been cruising at ISA-5 or so. The trip was 5:30 hrs and the route was IIRC 2300nm.

We flew our B2s back to UK to collect the B15s. Presumably we could all have taken a bomb bay tank each way instead of the tips. I expect the FEAF staff sent us along their established chain of way-stations and reasoned that these would have to be kept alive for diversion even if we could plan to overfly them. For my crew, the killer might have been FEAF’s difficulty in getting the MU at Wroughton to change the tank over just before Christmas 1962.

By top of descent for Tengah we had reached FL 520, which we (and you no doubt) knew to be 2000 feet beyond official safety in the case of pressurisation failure. How much higher would this cocky young pilot (White rating, 36 hours on type) have gone if he had not had the drag of the tip tanks ? Who knows !

redsetter 25th Mar 2012 12:53

pr00ne,

yes, there was no reason for the T.19 to have gunsights. The T.11 originally had radar "collimator" sights for pilot and pupil. I assume they would have been removed at the same time as the radar.

rs

Tinribs 25th Mar 2012 15:02

T19 Gunsights
 
I flew T19s at West Raynahm, 85 then 100. the aircraft did not have gunsights but on enquiring what the marks left by removing some coaming bits were I was told the previous mark 11s had one.

The aircraft were used for training Javelin navs and so that a visual cue could be matched to a radar picture gunsights were fitted. I was a bit sceptical about that story as I could not see how the nav in the back of the 11 could see a gunsight.

I spose it would have been possible for the trainee to vacate ejection seat and sit on jump seat for training purposes at hight level but it all seemed a bit far fetched.

Maybe the present question is a throwback to that orriginal story or maybe it was true. Find a mark 11 flyer

We were told the T19 could not have tip tanks because of the tip mounted pioto probe but the T17 did so all the suppoosed facts are a bit suspect. Certainly the T19 had speeds increased by 5kts because of different position of pitot

redsetter 25th Mar 2012 15:50

Tinribs,

as I understand it the T.11 carried two student radar/navigators. The one waiting his turn sat on the occasional seat by the pilot and watched the interception through the duplicate pilot's sight; the student in the back had the full radar scope, as per Javelin navigator.

rs

Wander00 25th Mar 2012 16:58

Talking about "5kts extra", when I joined 360, before the T17s arrived , we had a motley collection of T4s. B2s and an odd B6 (which I nearly got airborne in but SLOPS stopped me because I had to have flown CT in it before I could fly as a "target"). One of the B2s, WD 935, had been some sort of trials airframe which was about 2,500 lbs heavier than a "standard" B2. Hence if you hit the runway hard, you realised you had forgotten the 5kts extra for the heavier airframe. That aircraft had remained in Bomber Command black and grey. A Naval crew took it away for the weekend to Germany, and got arrested by the plods for having "stolen" it. I flew it to Woughton on is last flight, and it ended up in the Wales Aircraft Museum, but was I believe broken up when the museum folded. I think the nose may still be around.
