This is the story of the secret 'Black Lancasters', a specially trained RAF unit that was to drop the atomic bomb on Hiroshima on 6 August 1945. Why? Because the American B-29 Superfortress couldn't do it! Find out how this extraordinary situation arose and how the Americans managed to perform the mission in the end.

Per the video, the picked RAF crews were training in 1943 per the video (TR 7:56).

I'll have to look at this later, dealing with wife and a light left on in her car (battery dead).

Looks interesting; the RAF dam busters unit might have had some knowledge of hauling a heavy bomb and delivering it; but the Silverplate mod on the B-29 and the engine overheating issues were handled well before Enola Gay was dispatched.

Allied Air Forces

Royal Air Force
After the fall of the Dutch East Indies, the British RAF contributed six squadrons to the Pacific Air War.

During the period of greatest threat to Australia in 1942, Winston Churchill agreed to release three squadrons of Spitfires from service in England. This included No. 54 squadron plus two RAAF expeditionary squadrons serving in Britain, Nos. 452 and 457. The Spitfire was at the time the premier Allied air defense fighter.

The squadrons arrived in Australia in October 1942 and were grouped as No. 1 Wing. They were assigned the defense of the Darwin area in January of 1943. The Wing remained in that role for the remainder of the war. In late 1943 two additional RAF Squadrons were formed in Australia, Nos. 548 and 549. These relieved the RAAF Sptifire squadrons for eventual duty with the 1st RAAF Tactical Air Force.

No. 618 Squadron, a Mosquito squadron armed with the Wallis bomb for anti-shipping missions was sent to the Pacific in late 1944 but never saw active service and was disbanded in June 1945.

In 1945 two Dakota squadrons, Nos. 238 and 243, were sent to the Pacific to provide support for the British Pacific Fleet.
The RAF’s No. 205 squadron, which was stationed in Ceylon, was responsible for air services between Ceylon and Australia during the war.

Should the war have continued beyond VJ day, the RAF planned to send the “Tiger Force” to Okinawa to support operations against the Japanese home islands. As of 10 July 1945, the “Tiger Force” was planned to be composed of No. 5 (RAF) Group and No. 6 (RCAF) Group with 9 British, 8 Canadian, 2 Australian, and 1 New Zealand heavy bomber squadrons. The Force was to be supported by Pathfinder Squadron and a Photo/Weather Reccon squadron from the RAF and 3 Transport and one air/sea rescue Squadrons from the RCAF.

The Headquarters was to be established on Okinawa on 1 September 1945. No. 5 (RAF) Group, consisting of 4 Lancaster squadrons and 1 Mosquito pathfinder squadron was to be operational by 1 December. Four more Lancaster squadrons and the photo/weather Reccon squadron were to be in place by 1 January 1946. Lincoln equipped squadrons were to follow at the rate of four per month. The air/sea rescue squadron was to be assigned by 1 February. The RCAF transport squadrons were to be stationed at Cawnpore, India and equipped initially with Liberators and later with York aircraft. In July 1946 the Lancasters were to be replaced by Lincolns.

Beginning in September 1945 and likely continuing into the latter portions of 1945, Commonwealth forces would have executed Operation Zipper, liberating Singapore and opening the Straits of Malacca. Admiral Mountbatten would then have taken charge of the SouthWest Pacific Area, less the Philippines, from General MacArthur. Following completion of Operation Zipper a Commonwealth Air Force of 15 Mustang squadrons coming from RAF, RAAF, and RNZAF and commanded by an Australian would have been deployed for Operation Coronet, the invasion of Honshu, in the spring of 1946.

Lancaster's Of Tiger Force

CANADA’s Contribution to Tiger Force

Updated: June 2008
During the September 1944 Quebec Conference, Winston Churchill proposed that once Germany was defeated and the Allied attention turned towards the defeat of Japan. He proposed to transfer a large portion of Bomber Command or some 500 to 1000 heavy bombers to the Pacific theatre. The proposal was quickly accepted by President Franklin D. Roosevelt.

By late 1944, victory was more a matter of time rather than a question of being achieved and the decisions was made on 20 October 1944 to form a very large bomber force code named “Tiger Force”

Initially consisting of twenty-two squadron’s formed into three bomber groups. One Royal Air Force (RAF), one Royal Canadian Air Force (RCAF) and one contain squadrons from the Royal Air Force, Royal Australian Air Force (RAAF), Royal New Zealand Air Force (RNZAF) and South African Air Force (SAAF). The force was reduced to ten bomber squadron in two groups consisting of RAF and RCAF squadron’s and was later revised to include only eight squadron’s.

Tiger Force was to the based on Okinawa and would use Avro Lancaster’s, the newly arriving Avro Lincoln’s and Consolidated Liberator’s. Fighter escort duties were to be supplied by US Far East Air Force units and the Australian First Tactical Air Force as well as other Commonwealth units.

Aircraft marking for the Avro Lancaster and Lincoln’s was to be white upper-surfaces with black undersides. All Tiger Force was to be cancelled before being deployed this colour scheme was used on many RAF post-war Lancaster’s and Lincolns.
With the American bombing of Hiroshima and Nagasaki using Atom Bombs, Japan’s surrender followed shortly afterwards on 2 September 1945. But 5 September 1945 the Canadian Tiger Force Units, who had yet to begin training, received disbandment orders, while the RAF units were to remained on standby until they too received disbandment orders on 31 October 1945.
Tiger Force proposed formation included nine Wings and 22 Squadron’s:
The intended Order of Battle by 15 August 1945 stood as follows:

Air-Sea Rescue Squadron – 10 x Lancaster ASR III + 10 Catalina (not yet established)

Communications Flight: 6 x Auster + 2 x Expediter CI + 1 x Expediter CI (VVIP)

Special Missions Wing, RAF (forming Waddington) to be called forward late 1945

No. 9 Squadron, RAF: 20 x Lancaster BI (FE) / BI (Special)
No. 617 Squadron, RAF: 20 x Lancaster BI (FE) / BI (Special

No. 6 Group, RCAF

Communications Flight: 3 x Auster

No. 661 Wing, RCAF (forming Yarmouth, Nova Scotia, Canada) to be operational 1 Jan 1946

No. 431 Squadron, RCAF: 20 x Lancaster BI (FE) / BVII (FE)
No. 434 Squadron, RCAF: 20 x Lancaster BI (FE) / BVII (FE)

No. 662 Wing, RCAF (Force build-up at Wing) to be operational not specified

No. 419 Squadron, RCAF: 20 x Lincoln BII
No. 428 Squadron, RCAF: 20 x Lincoln BII

No. 663 Wing, RCAF (forming Debert, Nova Scotia, Canada) for deployment early 1946

No. 420 Squadron, RCAF: 20 x Lincoln BII
No. 425 Squadron, RCAF: 20 x Lincoln BII

No. 664 Wing, RCAF (forming Scoudouc, New Brunswick, Canada) for deployment early 1946

No. 405 Squadron, RCAF: 20 x Lincoln BII
No. 408 Squadron, RCAF: 20 x Lincoln BII


It is interesting to note that this initial list for No. 6 Group, RCAF shows Lancaster’s as Mk. BI (FE) and BVII (FE) and also included Lincoln BII’s. When in fact all units forming in Canada were made up of Lancaster’s that had been flown back to Canada and were in fact Canadian made Lancaster Mk.X. (see below).

CANADA’s Lancaster’s contribution to Tiger Force

The Canadian group, contained No’s 661, 662, 663 and 663 (Heavy Bomber) Wings and was to be equipped with aircraft and personnel coming directly from squadron’s already operating in England within No. 6 Group, RCAF.

As soon as formation orders had been issued, the Canadian squadrons were re-equipped with Canadian built Lancaster Mk.X’s from the FM and KB serial number series. These aircraft, which had been built at the Victory Aircraft Production in Malton, Ontario, had been steadily arriving in England since mid 1944; and would allow all of the squadron’s to operate the same Lancaster variant.

The Wings formations were as follows:

In total 141 Lancaster Mk.X’s were allocated to Tiger force, however with the unforeseen disbandment Tiger Force the Canadian Government was faced with an interesting problem. Since the original intention was for the RCAF units to be re-equipped with Canadian built Avro Lincolns as soon as these aircraft could be made available. The Lancaster Mk.X’s, although Canadian made, had been transferred to RAF ownership and for several months after disbandment; Canadian built aircraft were being operated in Canada, by the RCAF, but did not belong to the Canadian government. The problem was resolved by late 1945 or early 1946 when ownership of the Canadian made Lancaster’s which had been returned to Canada were returned to the Canadian Government ownership, Even so the Lancaster maintained their RAF serial numbers.

With no requirement for a heavy bomber force the Canadian Government decided to place hundreds of Lancaster aircraft into long-term storage, in various disused air based in Eastern Canada. However after several years it was realised that the damp weather environment was not best suited for long term aircraft storage.

The decision was then made to relocate the stored Lancaster’s a drier climate which would be more indicative for aircraft storage. This so called ideal location was determined to be in the Western Canada prairie Province Alberta, where several closed British Commonwealth Air Training Plan (BCATP) stations were allocated for this task. By the late 1940, many of the Lancaster’s had been flown out to Alberta and were to remain there until the early 1950’s

They force would likely have remained in storage, awaiting their final date to be scrapped, if increasing international tensions between the East and West had not reached point where the Canadian Government ordered the RCAF to activate seventy Lancaster’s and modify them for a variety of roles including Maritime reconnaissance and anti-submarine warfare.

Canadian Lancaster’s were also to be modified by the Canadian Government for Aerial Reconnaissance, Air-Sea Rescue, Navigational Training, Photo-Reconnaissance and civilian transport duties the later as Avro Lancastrians.

Appendix IX: Tiger Force

At the Quebec Conference of September 1944, the British Prime Minister Winston Churchill proposed to transfer a large part of Bomber Command to the Pacific, comprising from 500 to 1,000 heavy bombers, once Germany was defeated. US President Franklin D. Roosevelt accepted the offer, stating that a "long and costly struggle" still lay ahead of the Allies.

The proposed force was soon scaled back to 22 squadrons in three groups: one British Royal Air Force (RAF), one Royal Canadian Air Force (RCAF) and one from various air forces. By the end of the war this had been scaled back to 10 squadrons in two composite groups, made up of RAF, RCAF, Royal Australian Air Force (RAAF) and Royal New Zealand Air Force (RNZAF) squadrons. Tiger Force was to have been based on Okinawa and would have used Avro Lancasters, Avro Lincolns (the latest development of the Lancaster) and Consolidated Liberators.

The bomber force would take its escorts from the fighter units of the U.S. Far East Air Force, the Australian First Tactical Air Force and/or other Commonwealth units.

The colour scheme for Tiger Force aircraft was white upper-surfaces with black undersides; this scheme, despite the cancellation of operations against Japan, was apparent on many post-war Lancasters and Lincolns. To enable the aircraft to operate at the long distances involved, flight refuelling was to have been employed, using equipment developed by Flight Refuelling Ltd.

Tiger Force was officially disbanded on October 31, 1945.

I've been researching the UK "Tiger Force" which was to start flying from Okinawa for Operation Downfall. Air-to-air refueling was not on the table in the late summer of 1945.

These are crib notes from "LANCASTER The Second World War's Greatest Bomber" by Leo McKinstry Copyright 2009, John Murray publishers isbn 978 0 7195 2363 2.


pages 496 - 497

Air-to-air refueling "not fully practicable." It would take 3 planes
to do the work of one plane.

Page 497

UK Air Ministry tried 1,200 gallon saddle tank above the wing of the
Lancaster to get 3,650 gallons fuel with 8,000 lb payload to 4,340
miles (one way distance, not radius of action) It was structurally
unsound, which was found upon early full load landings with landing
gear collapses.

Pages 497 - 498

UK Air Ministry had Avro design a 'tropicalized ' Lancaster with the
mid-top machine gun turret was replaced by a 400 gallon fuel tank and
the plane had Gee, Loran, and the "Rebecca" half of the
Rebecca/Eureka beacon system. This plan was considered by Avro the
Lancaster Mark I Far East (FE), the Avro Lincoln was considered the
Lancaster Mark VII FE. The Mark VII had the identical Gee, Loran, and
the "Rebecca"

A fully tricked out Lancaster Mark I Far East (FE) had a one way range
of 3,180 miles.

The Tiger Force had a radius of action of at least 1,000 miles with the Lancaster
Mark I Far East (FE) and the Lincoln Mark VII FE were better. Operating from
Okinawa, the RAF Tiger Force didn't really need air-to-air refueling, even
if they brought some of the air-to-air refueling kits.

Rebecca meant the British bombers could beacon bomb in support of the
troops ashore in Kyushu. The 10cm UPN-1/2 beacons in Gen. Kenney's wish
list for Olympic meant Gee-H type 'cat and mouse' bombing was on the table,
if the Lancaster Mark I Far East (FE) also had H2S radar.
Further internet searches turned up the following on the first two Tiger Force squadrons and their intended target in late Oct 1945.

Did some more research on TIGER FORCE.


General Spaatz specifically requested that the RAF have two 'Tallboy'
Squadrons of Lancasters operational on Okinawa by October 15 1945. He
required them to attack specific targets on the Japanese mainland
before the invasion of Kyushu on November 1 1945.

He required them to take out several major bridges between Tokyo and
Shimoniseki as well as the Kammon Tunnel linking Honshu and Kyushu
using their 'Tallboy' and 'Grand Slam' bombs.

No 9 and 617 Squadrons of RAF were selected for this task.

10 Squadrons of conventional Lancaster heavy bombers along with their
Mosquito pathfinders were to be deployed to Okinawa also, rising to 20
squadrons by the years end.

I later found out that other than "Special Missions Wing, RAF" (the Damnbusters and the 2nd tallboy/Grand Slam sqd.), most of Tiger Force would be flying 141 Canadian built Lancaster Mk. X, which definately were not air-to-air kit equipped.

See this:

It is interesting to note that this initial list for No. 6 Group, RCAF
shows Lancaster's as Mk. BI (FE) and BVII (FE) and also included
Lincoln BII's. When in fact all units forming in Canada were made up
of Lancaster's that had been flown back to Canada and were in fact
Canadian made Lancaster Mk.X.

Lancaster's Of Tiger Force

CANADA's Contribution to Tiger Force


Updated: June 2008

During the September 1944 Quebec Conference, Winston Churchill
proposed that once Germany was defeated and the Allied attention
turned towards the defeat of Japan. He proposed to transfer a large
portion of Bomber Command or some 500 to 1000 heavy bombers to the
Pacific theatre. The proposal was quickly accepted by President
Franklin D. Roosevelt.

By late 1944, victory was more a matter of time rather than a question
of being achieved and the decisions was made on 20 October 1944 to
form a very large bomber force code named "Tiger Force"

Initially consisting of twenty-two squadron's formed into three bomber
groups. One Royal Air Force (RAF), one Royal Canadian Air Force (RCAF)
and one contain squadrons from the Royal Air Force, Royal Australian
Air Force (RAAF), Royal New Zealand Air Force (RNZAF) and South
African Air Force (SAAF). The force was reduced to ten bomber squadron
in two groups consisting of RAF and RCAF squadron's and was later
revised to include only eight squadron's.

Tiger Force was to the based on Okinawa and would use Avro
Lancaster's, the newly arriving Avro Lincoln's and Consolidated
Liberator's. Fighter escort duties were to be supplied by US Far East
Air Force units and the Australian First Tactical Air Force as well as
other Commonwealth units.

Aircraft marking for the Avro Lancaster and Lincoln's was to be white
upper-surfaces with black undersides. All Tiger Force was to be
cancelled before being deployed this colour scheme was used on many
RAF post-war Lancaster's and Lincolns.

With the American bombing of Hiroshima and Nagasaki using Atom Bombs,
Japan's surrender followed shortly afterwards on 2 September 1945. But
5 September 1945 the Canadian Tiger Force Units, who had yet to begin
training, received disbandment orders, while the RAF units were to
remained on standby until they too received disbandment orders on 31
October 1945.

Tiger Force proposed formation included nine Wings and 22 Squadron's:

The intended Order of Battle by 15 August 1945 stood as follows:


Air-Sea Rescue Squadron - 10 x Lancaster ASR III + 10 Catalina (not
yet established)

Communications Flight: 6 x Auster + 2 x Expediter CI + 1 x Expediter CI (VVIP)

No. 207 Squadron, RAF: 20 Lancaster BI (FE) / BVI (FE)

Special Missions Wing, RAF (forming Waddington) to be called forward late 1945

No. 9 Squadron, RAF: 20 x Lancaster BI (FE) / BI (Special)
No. 617 Squadron, RAF: 20 x Lancaster BI (FE) / BI (Special


No. 6 Group, RCAF

Communications Flight: 3 x Auster

No. 661 Wing, RCAF (forming Yarmouth, Nova Scotia, Canada) to be
operational 1 Jan 1946

No. 431 Squadron, RCAF: 20 x Lancaster BI (FE) / BVII (FE)
No. 434 Squadron, RCAF: 20 x Lancaster BI (FE) / BVII (FE)

No. 662 Wing, RCAF (Force build-up at Wing) to be operational not specified

No. 419 Squadron, RCAF: 20 x Lincoln BII
No. 428 Squadron, RCAF: 20 x Lincoln BII

No. 663 Wing, RCAF (forming Debert, Nova Scotia, Canada) for
deployment early 1946

No. 664 Wing, RCAF (forming Scoudouc, New Brunswick, Canada) for
deployment early 1946

No. 405 Squadron, RCAF: 20 x Lincoln BII
No. 408 Squadron, RCAF: 20 x Lincoln BII


It is interesting to note that this initial list for No. 6 Group, RCAF
shows Lancaster's as Mk. BI (FE) and BVII (FE) and also included
Lincoln BII's. When in fact all units forming in Canada were made up
of Lancaster's that had been flown back to Canada and were in fact
Canadian made Lancaster Mk.X. (see below).


CANADA's Lancaster's contribution to Tiger Force

The Canadian group, contained No's 661, 662, 663 and 663 (Heavy
Bomber) Wings and was to be equipped with aircraft and personnel
coming directly from squadron's already operating in England within
No. 6 Group, RCAF.

As soon as formation orders had been issued, the Canadian squadrons
were re-equipped with Canadian built Lancaster Mk.X's from the FM and
KB serial number series. These aircraft, which had been built at the
Victory Aircraft Production in Malton, Ontario, had been steadily
arriving in England since mid 1944; and would allow all of the
squadron's to operate the same Lancaster variant.

In total 141 Lancaster Mk.X's were allocated to Tiger force, however
with the unforeseen disbandment Tiger Force the Canadian Government
was faced with an interesting problem. Since the original intention
was for the RCAF units to be re-equipped with Canadian built Avro
Lincolns as soon as these aircraft could be made available. The
Lancaster Mk.X's, although Canadian made, had been transferred to RAF
ownership and for several months after disbandment; Canadian built
aircraft were being operated in Canada, by the RCAF, but did not
belong to the Canadian government. The problem was resolved by late
1945 or early 1946 when ownership of the Canadian made Lancaster's
which had been returned to Canada were returned to the Canadian
Government ownership, Even so the Lancaster maintained their RAF
serial numbers.

With no requirement for a heavy bomber force the Canadian Government
decided to place hundreds of Lancaster aircraft into long-term
storage, in various disused air based in Eastern Canada. However after
several years it was realised that the damp weather environment was
not best suited for long term aircraft storage.

The decision was then made to relocate the stored Lancaster's a drier
climate which would be more indicative for aircraft storage. This so
called ideal location was determined to be in the Western Canada
prairie Province Alberta, where several closed British Commonwealth
Air Training Plan (BCATP) stations were allocated for this task. By
the late 1940, many of the Lancaster's had been flown out to Alberta
and were to remain there until the early 1950's

They force would likely have remained in storage, awaiting their final
date to be scrapped, if increasing international tensions between the
East and West had not reached point where the Canadian Government
ordered the RCAF to activate seventy Lancaster's and modify them for a
variety of roles including Maritime reconnaissance and anti-submarine
warfare.

Canadian Lancaster's were also to be modified by the Canadian
Government for Aerial Reconnaissance, Air-Sea Rescue, Navigational
Training, Photo-Reconnaissance and civilian transport duties the later
as Avro Lancastrians.

More crib notes.


TIGER FORCE IN OLYMPIC/MAJESTIC NOTES

1) The UK Tiger Force was going to be under Kenney's FEAF and _not_ the 8th Air Force.

2) The first two Lancaster squadrons would carry Tall boys and arrive
operationally from Canada 15 October 1945...just in time for the
opening bell on the two-week preperation air bombardment for Operation
Olympic/Majestic.

This is from the Spaatz Papers dated 7 and 3 August 1945.

See --
7 August 1945
Attended meeting at Adm. Nimitz
headquarters at 0930.

Held press conference in USASTAF headquarters at 1100 at
which were present Admiral Parnell. Gen. Farrell . LeUay and
other officers or this headqurters . Discussion centered around
atomic bomb .

Had as guest for lunch Capt. Bouverie. Naval British Liaison
officer with Nimitz headquarters.

Discussion with Lindsay reference RAF Squadrons. Dispatched
message to Washington after receiving message from Kenney concurring
in decision to place them under him. but re-emphasized to Lindsay that
any message effecting both USASTAF and FEAF be sent through Kenney.
1700-1900 Open House held at Giles with all Wing Commanders present
as well as all Chiefs of Sections of this and the 20th AAF headquarters.

To ComGen USASTAF GUAM for Spaatz

A 1711 August . Have received your message that you
cannot give firm offer of 2 Tallboy Squadrons for 10 days . This
will make it too late for squadrons to arrive in time should they
be required. We are therefore making all arrangements as if you
retain them. Loading of shipping with ground equipment is now
being moved to Canada to take advantage of shipping available
there. With these arrangements we hope to make destination by
15 October. Have informed Nimitz of proposals and sailings.

Currently reading through "History of the Second World War, Grand Strategy, Volume V" by John Ehrman, on page 519 it states the following:
Sir Charles Portal replied that there was a distinction. The Lancaster bomber, if refuelled in the air, had a range nearly approaching that of the B.29. Without refuelling in the air these aircraft had a range of 800-900 miles.
Now, my question, is he talking about what we today consider in air refueling or some different type of in air refueling? I have never read that anyone did in air refueling from one plane to another while flying.

PA474 the BoB flight's Lancaster was built for operations in the Far East. Owing to the war ending it did not see service as a bomber. It was rebuilt as an inflight refueling aircraft. It later went to Cranfield where it was used for airflow test on aircraft wings. These were carried upright, looking like the dorsal fin of a fish. On retirement it was transferred to the BoB Flight.

This is the story of the secret 'Black Lancasters', a specially trained RAF unit that was to drop the atomic bomb on Hiroshima on 6 August 1945. Why? Because the American B-29 Superfortress couldn't do it! Find out how this extraordinary situation arose and how the Americans managed to perform the mission in the end.
That was very interesting.I had no idea that all of that went on.

Avro 683 Lancaster B Mk. III (G-AHJW c/n RSLB.127336) Flight Refuelling Ltd

Photograph from Flight Refuelling Ltd.

10/31/2009. On April 25, 1946 the Ministry of Supply (MoS) had four former RAF Lancaster B.Mk.IIIs (LL809, LM681, LM639, ED866) registered as
G-AHJT to G-AHJW respectively, and subsequently supplied them to Flight Refuelling Ltd, at Ford Aerodrome, Littlehampton, Sussex, UK. They were converted into two pairs of tanker and receiver aircraft at Staverton, and were used in perfecting the company's looped-hose aerial refueling techniques.

In co-operation with British South American Airways a series of flight refueling trials over the Atlantic were conducted. The first trip, typical of the whole series, took place on 28 May 1947, when a Lancaster flown by Air Vice-Marshal D. C. T. Bennett left London Airport, was refueled in mid-Atlantic with 1,700 gal (7,728 l) of petrol by an Azores-based Lancaster tanker, and completed the 3,433 mls (5,525 km) flight to Bermuda non-stop. Till August 11, 1947 eleven weekly return flights were accomplished.

The MoS had the four aircraft deregistered June 4, 1948, ten weeks later, August 13, they were registered to Flight Refuelling Ltd. The company became heavily involved in the Berlin Airlift for a year, delivering 7 million gal (32 million l) of fuel, the four Lancasters contributing their share.

G-AHJW, however, was lost on November 23, 1948. Returning to the UK for maintenance, it crashed into trees on fog-covered high ground at Conholt Park near Chute, Hampshire. Of the eight onboard the Canadian wireless operator was the sole survivor.

The remaining three Lancasters were scrapped in 1950 and 1951.

Avro_Lancaster-1.gif


Posted for fair use.....

AIRFRAME

To begin the story of the Lancaster Airframe, we must go back to the Manchester, as this is where the venerable Lanc' started life.
In September 1936, the Air Ministry issued specification P13/36. This was to be a twin engined medium bomber with dive-bombing capability. AVRO, among other British Companies, answered this specification with a submission to the Ministry in January 1937. The aircraft was called-Type 679, later to become the Manchester.
The Manchester represented an enormous challenge to AVRO, as they had no experience of all-metal stressed skin construction. Nor had they attempted such a large aircraft before. The initial design was to have a wingspan of 72ft, and a fuselage length of 69ft. All of the bomb load was to be carried in the fuselage, and all fuel and oil to be contained in the wings. The estimated gross weight, was 37,777lbs. The dihedral angle on the outer wings was 7 degrees. The tailplane carried twin fins, although this was probably due more to tradition rather than technical reasons.
The heart of the Manchester, was the combined wing & fuselage centre section.

lancentresection.jpg


The structure of the wing centre section was based on two spars of simple construction, both consisting of mass booms and plate webs. Running at right angles were two fuselage longerons which formed the basis of the cabin floor & the bomb bay roof. The aircraft needed to be "simple" to aid easy manufacture, and a high rate of production. Light alloy was used for the manufacture of most components, and stampings & pressings were used to minimise hand fitting work.

nosection.jpg
frontfuselage.jpg

The fuselage was a light alloy monocoque structure, with skins flush riveted to a framework of formers & stringers. It comprised four sections, making for easy transport, both when new, and after a repairable accident.

rearfuselage.jpg


tailfuselage.jpg


In addition to its two spar construction the wing incorporated ribs built of plate webs and drawn angle flanges. The skins were flush riveted and skin overlaps were minimised.
Flying control surfaces were to be ball bearing mounted, operated by cables sized to minimise circuit stretch.

After acceptance by the Air Ministry, a contract was issued for the manufacture of two prototypes. On 1st July 1937, a further contract was issued, for the supply of 200 production aeroplanes. In January 1937, AVRO had already decided, that changes needed to be made to the design. This was quite common, at the prototype stage. The fuselage length changed to 69ft 4.5ins, and changes were made to the shape & skin curvature, to make design and manufacture more straightforward. From a previous 72ft, the wingspan went up to 80ft 2ins. Tailplane span remained at 28ft, but the fins and rudders were moved fully outboard. The aerofoil section now selected was the NACA 23000 series, 23018 over the centre section, 23018 reducing to 23009 for the outer wing. Avro production experience up to this time, was largely as a woodworking firm. A production contract for 1,000 Bristol Blenheim Aircraft in 1937, gave the company valuable experience of stressed skin construction. Avro were breaking new ground, in the milling of Hiduminium L40 spar sections of the size required for this aeroplane. The main centre section incorporating the parallel cord wing centre section, formed the heart of the aircraft. The wing incidence was set at 4 degrees up to the fuselage centre line.

wingsection.jpg


A high proportion of the fuselage length was of constant cross section, with heavier frames at the transport joints. This reduced the amount of tooling required. When fully assembled, the bomb bay was 33ft 3ins long, by 5ft 6ins wide. Bomb bay doors were 2ft 8ins wide. Operated hydraulically with sequenced hydraulic locks.
As with the fuselage design, the wing was divided into transportable sections. The 28ft 6" parallel wing centre section passed through the main fuselage section. The undercarriage bays & the Rolls Royce X-24 Vulture engines were contained in nacelles mounted at the outboard ends of the wing centre section. the depth of the parallel section was 2ft 11", 18% thickness/chord ratio being selected at the best compromise between airframe strength & aerodynamic drag. The fuel tanks were mounted between the wing spars, & held in place by simple strap & turnbuckle attachments. Access was gained from the underside of the wings.

fueltankinwing.jpg


The outer wing was a straight tapered two spar assembly from rib number 22 to rib number 5. Span of the outer wing structure, was 21ft 5.5".

outerwing.jpg


At the root-end transport joint was another braced frame rib. Outboard of this were all pressed ribs, with flanged lightening holes, and riveted vertical stiffeners. The outer wing tapered from 18% thickness/cord, down to 9%. The main spar was likewise tapered. Detachable wing tips of 4ft 6" span were added to the outer wing at rib 5.

wingtip.jpg


The wings had detachable trailing edges incorporating the flap assy, and ailerons. The centre section had a hinged, detachable, leading edge, for easy access. The flaps were simply hinged in two sections to accomodate the dihedral change and were operated by a single push-pull tube, with a series of links. The aileron hinges were externally mounted. Engine subframes & undercarriage attachments were bolted to the front spar/engine rib joints in the centre section. The engine subframe used a pin-jointed tube & socket structure.
The tailplane & fin layout made for simple construction & attachment. With a width of 28ft, the tailplane was made in two halves. It was of a two spar and pressed rib construction, with light stringers on the same principle as the wing. It used constant section spar boom extrusions & tapering plate webs. The spars extended beyond the aerodymanic surface to secure the fin posts at simple bolted joints. The prototype fins were 8ft 10" tall. The rudders & elevators were carried on hinge brackets. The flying control surfaces were all metal, the elevator having a manually operated trim tab, as did the rudder.

The British Had A Plan To Drop Anthrax Laced Cattle Feed Over Germany In 1942
Biological weapons delivered by RAF Lancaster bombers could have led to the deaths of hundreds of thousands.

Under the darkly ironic codename Operation Vegetarian, the United Kingdom developed a scheme to respond in kind should Nazi Germany unleash a biological warfare attack on the British mainland during World War II. The fear of Hitler employing germ warfare was very real, intensifying after the fall of France in the summer of 1940, after which the United Kingdom was expected to be the next major target of the German military conquest of Western Europe.

Chair of the Bacteriological Committee in the United Kingdom, Lord Maurice Hankey urged Prime Minister Winston Churchill to look into the practicality of biological weapons “so as to put ourselves in a position to retaliate if such abominable weapons should be used against us.” Churchill agreed and set up a team of scientists at Porton Down, a top-secret laboratory in Wiltshire, southwest England, to embark on a project examining options for reprisal — should it ever be needed.

The choice of biological weapon fell on anthrax. Caused by the bacteria Bacillus anthracis, anthrax is a familiar agent of biological warfare. Anthrax spores occur in nature and can be produced in a lab. The spores can be delivered in the form of powders or sprays, or via contaminated food and water, and can persist in the environment for decades. Humans contract the disease when spores enter the body via a cut or scrape (cutaneous anthrax), via inhalation (pulmonary) or by consumption of infected meat (gastrointestinal). While pulmonary is the most lethal (around 80% mortality, according to the U.S. Food and Drug Administration), the gastrointestinal version used for Operation Vegetarian still results in death in between 25% and 75% of cases. These figures all depend on levels of exposure and availability of antibiotics, which can usually treat cutaneous anthrax.


message-editor%2F1596790258373-lord_ankey.jpg

WIKIMEDIA COMMONS
Maurice Hankey, in 1934.
Tests were conducted on Gruinard Island on Scotland’s north coast and on Penclawdd off the Welsh coast. The former was bombarded with anthrax spores from the air by Vickers Wellington medium bombers, killing the island’s resident sheep within three days. Penclawdd, meanwhile, was attacked by a Bristol Blenheim in a follow-up test. The twin-engine bomber delivered a single device from around 5,000 feet. Its target was two lines of sheep — 60 in all — placed downwind of the impact point. The three pounds of liquid anthrax spores were found only to have killed two animals outright. Nevertheless, after these trials, anthrax was judged 100 times more effective than a chemical agent on a weight-for-weight basis.




January 1942 saw the go-ahead for Britain’s production of anthrax on a large scale with the War Cabinet simultaneously recommending that it be used against Germany as a reprisal weapon if Britain was attacked using germ warfare. Porton Down scientists by 1943 had produced an operational stockpile of five million cattle cakes infected with anthrax spores. Under Operation Vegetarian, these were to be delivered by Royal Air Force Avro Lancaster bombers — 12 in total — that would drop the deadly cargo over northern Germany. Aiming for farmland rather than population centers, the scheme was planned to wipe out the country’s beef and dairy cattle. As well as removing a vital food source, the bacterium would also work its way into the human food chain that was expected to lead to fatalities numbering tens or hundreds of thousands, if not millions.
The Lancaster was an obvious choice for the mission, had it ever been sanctioned. The four-engine type had entered service in December 1941 and would go on to excel both as a conventional heavy bomber and in a range of more unconventional missions, including dropping the 22,000-pound “Grand Slam” earthquake bomb and the “Upkeep” bouncing bombs that breached German dams in the raids of May 1943.





Of course, Hitler never sanctioned the use of biological warfare for reasons that have never been fully explained. It’s been speculated he may have had an aversion to germ warfare based on his experience of being gassed in World War I or his phobia of microbes. The Nazis nonetheless carried out research in this area including establishing an entomological institute to study the physiology and control of insects that inflict harm to humans.

British anthrax stockpiled under Operation Vegetarian was ultimately destroyed at the end of the war — all but two crates of infected cattle cakes were incinerated. It’s not clear what became of the remainder, but the spores they contained were still judged to be effective as of 1955.

The defeat of Nazi Germany was not the end of British interest in biological warfare. On the contrary, with the beginning of the Cold War, the focus now turned to the Soviet Union, which had begun its own experiments in the field before World War II and which had captured a Japanese biological weapons facility in Manchuria.
The effect of the anthrax tests on the British islands was dramatic and long-lasting, including reports of livestock deaths on the Scottish mainland after an infected sheep carcass from Gruinard was washed up on a beach. According to Porton Down’s official account, the mile-long island was not fully decontaminated until 1986 following a painstaking sterilization process amid mounting public pressure.

Today, Porton Down continues to play a role in biological and chemical weapons – rather than developing them for potential wartime use, it’s now tasked with developing countermeasures. It was also a focus of attention in the wake of the poisoning by nerve agent of former Russian military officer and double agent Sergei Skripal and his daughter, Yulia Skripal, in nearby Salisbury in March 2018.

Operation Vegetarian — details of which for many years remained within classified the National Archives — is clearly one of the more extreme plans hatched by the Allies during World War II, but it’s a clear reminder of the kind of thinking at the highest military levels during one of the darkest periods in Europe’s history.
