If the cheeses served are Munster, Maroilles, Pavé de Lille, Livarot, Avesnois & Camembert, it is forbidden to remove your mask.I'm told the wine and cheese was fabulous.
St. Felicien, accompanied by a half bottle Charpoutier-Banyuls. A silver coffee spoon is an excellent way to transport the ripest examples to the savouring mouth. Although a mother of pearl caviar spoon will also suffice.If the cheeses served are Munster, Maroilles, Pavé de Lille, Livarot, Avesnois & Camembert, it is forbidden to remove your mask.
Problem is timing.
All three planes flew within a few months of each other, except the Skua already had the folding wing and bits and pieces for catapult launch and arresting landing.
Next thing is that the Skua was a dive bomber, in that it had dive brakes.

For some reason the land based dive bombers didn't have dive brakes. They could dive, they could pull out without breaking. They just may have had to pull out sooner/higher and have less accuracy. This assumes that the RAF ever funded a dive bomber sight for any of them.
Stressed for dive bombing and actually dive bombing the way the Americans and Germans and Japanese did it are not quite the same thing.
You could probably modify both planes to substitute for the Skua, the question is how long would it take and what was the availability of Merlin's at that particular time.
If Blackburn could not get Mercury radials because all available Mercuries were going to Blenheim production could you get Merlin II/III away from Hurricanes and Battles?
The engine availability thing may have swapped back and forth a few times over 1937-39. But you have to pick a plane and engine combo and stick with it.
And finally once you are done, is it really going to be any better than the Skua? Or should I say significantly better?
From wiki and is lacking in a few details.
"The first prototype Fulmar, which acted as a "flying mock-up", was powered by a single Rolls Royce Merlin III engine, which was capable of generating up to 1,080 hp (810 kW).[9] Flight testing revealed the prototype's performance to be relatively poor, the highest speed it could attain being 230 mph (370 km/h). Following the adoption of the more powerful Merlin VIII engine – a variant unique to the Fulmar and with supercharging optimised for low-level flight, as well as various aerodynamic improvements made to the airframe, the prototype's speed was increased to 265 mph (426 km/h) when flown at an altitude of 7500 ft (2286m)"
Now in 1937-38 the the Merlin made 1030hp at 16,250ft, not 1080hp.
The Speed of the prototype Fulmar is not given with an altitude.
The P. 4/34 was good for 284mph at 15,000ft (and perhaps a bit better at 17,000ft? see speeds for Hurricane I with same engine). Where did the 54mph go?
Or was the Fulmar prototype flying somewhere around 5,000ft to 7,500ft? A Hurricane I with a two pitch prop will loose over 30mph of speed when flying at 6500ft compared to 17,000ft. We don't know the answer for sure but something is off.
The production Fulmars got a different supercharger gear and they could make a lot more power down low than the Merlin III and that helped get the Fulmar back up to 255-265mph at the Altitudes the Skua did 225mph. Remember the Skua had 905hp at 6,500ft.
There is little doubt the P.4/34 and the Henley would have been a bit faster than the Skua but without the Merlin VIII the difference would have been a lot less marked at the 5-7,500ft altitude.
You could have made the Skua go faster by giving it an engine that peaked at 14,-15,000ft but it would have been slower at 5,000ft where more of the enemy spotter aircraft and bombers were.
Strictly the Fulmar prototype was the first production aircraft N1854 which flew in Jan 1940 and not the K7555 the second P4/34 prototype.Problem is timing.

I am unclear on this one.The engine specified was a moderately supercharged Merlin 'H' (aka Merlin III)
The Merlin VIII used 6.313 gears and was the R.M.3. specification. At least according to the R-R Heritage Trust "The Merlin in Perspective"K7555 was then tested again in 1939 with a Merlin VIII.
And 230kts is just about 265mph. The 10,000ft would line up pretty well with the phantom R.M.1.M engine though.O.8/38 called for a max speed of at least 230 knots for an operational height of 10,000 feet amongst other things.
A lot of questions. Not sure I have all the answers but here goes.Something that came up on the Dinger Aviation .net pages was the claim that the Skuas operating around Scapa Flow in Sept 1939 had a lot of trouble being directed to aircraft that had been seen by ground observers. At the time the Skua did not have voice radio and only had radios that could be used with code. 1938-39 radio technology was not always what 1940 radio technology was and 1943-44 was almost another world.
The voice radio did exist, why the Skuas did not have it I don't know. Speculation is you need the extra black boxes, another separate antenna and the range is going to be rather short in any case.
This may or may not have anything to do with two seat fighter requirement.
Did the single seat biplanes have radios? what was their range? how far did the single seat biplanes fly from the carriers?
How far from the carrier did thy have to be to intercept a 120-150mph strike aircraft?
How far do you have to be to set up an intercept on a 200mph strike aircraft?
If you increase your "protection" radius by 50% you may increase the area you need to cover by double.
Just somethings to consider.
re the T.1083/R.1082 command & liaison set carried by the Skua
The T.1083/R.1082 combined command & liaison set was the standard FAA kit for multi-crew aircraft from about 1936, along with the R.1110 DF/receiver for homing on the Type 72 shipboard homing beacon. This equipment was carried by the Shark, Swordfish, Walrus, Skua, Roc, early Fulmar, and some early Albacore. (maybe others also?)
In the form carried by these aircraft the set was capable of CW, ICW, and R/T(voice) for air- to-air and air-to-ship communication. It also had a built in capability for acting as an intercom for the crew.
Where the myth began that it was not capable of voice communication between aircraft or air-to-ground I do not know, but it is possible that the myth started due to the equipment sometimes being used as a shipboard radio set. When it was used as ship-to-aircraft equipment it usually did not have the voice capability/equipment included, instead transmitting/receiving in ICW(Morse) for communication or CW for DF purposes. This was due to there being other much more capable shipboard R/T(voice) sets
Radio range.
From a link I posted on the "FAA Seafire vs Corsair" thread, the TR9 HF radio set (T.1083/R.1082 combination) introduced to the RAF from 1933 and standard equipment until 1940 and beyond when VHF radios began to be introduced, had an HF voice transmission ground to air range of about 35-40 miles but only 5 miles air to air. Added to that the reception quality could be variable.
These sets were certainly fitted to the Sea Gladiators delivered from late 1938. Not sure about the earlier Nimrods.
Perhaps that's where our improved or second version of the Skua should be directed, to the RAF. From 1939-40 the Stuka showed the RAF what land based dive bombers could do in Poland, France and the Low Countries. Build a new version of the Skua without folding wings, arrestor hook (and the hook's internal bracing), catapult fittings, etc. for the RAF. If the RAF could make use of the Vengeance in SEA, they can make earlier use of the Skua.Next thing is that the Skua was a dive bomber, in that it had dive brakes. For some reason the land based dive bombers didn't have dive brakes. They could dive, they could pull out without breaking. They just may have had to pull out sooner/higher and have less accuracy.
The jigs etc. were with Boulton Paul to make the Roc. Blackburn having no space left whilst they moved on to build Bothas and Swordfish etc. and develop the unmentionable device. Boulton Paul would doubtless suggest a dive bomber Defiant and switch Defiant production from turret fighters to dive bombers. The RAF were having cold feet over the turret fighter anyway.Perhaps that's where our improved or second version of the Skua should be directed, to the RAF.

Nevertheless Boulton Paul had to make Rocs as Blackburns could not. Just as Blackburn got the Swordfish shadow contract because Fairey were giving up on the Swordfish and moving on to the Albacore and further looking towards the Barracuda. It might have been Blackburn made Albacores but the delay to set that up was by-passed by Fairey passing on the Swordfish production line. The Blackburn design capacity was over burdened which was no help with their performance spending the war trying to make the unmentionable, unsuccessfully.But just how true is that statement about the jigs?
Skua production began in mid-1938 and Blackburn continued to deliver Skuas until Oct 1939. Over half the 190 production Skuas left the factory after March 1939.
On the other hand Boulton & Paul had begun to deliver production Rocs in March 1939 and had delivered at least 40 before the final Skuas rolled off the production line. Roc production continued until Aug 1940.
The Blackburn built Swordfish were not built at the Blackburn Brough factory but at a new shadow factory at Sherburn-in-Elmet constructed for that purpose. The contract for them was awarded in Nov 1939 and the first production aircraft first flew on 1 Dec 1940. That factory used many of the Swordfish jigs from the Fairey production line that had moved on to Albacore production.
