The Martin mid upper turret developed for the B-26 was an excellent design that was also used on the B-24 (not the B-25 which was a Bendix design). The British thought very highly of it and replaced the FN mid upper on late model Lancasters (Most Mk VIIs and Mk Xs) and all Lincoln Mk Is with it.Grant, just a quick note, here.
Martin developed a native power turret for their B-10, their YB-10 first flying in 1932, a year before Boulton-Paul's Overstrand.
Martin went on to produce native power turrets for their designs and other aircraft manufacturers (like NAA's B-25) and still manufactures them today as Lockheed-Martin.
Unfortunately one of the lessons that the RAF refused to learn from the Spanish civil war is that bombers need escorts.Bombing of Guernica.
That showed the power of the bomber and the idea of bombing. So based on that the idea of not buying bombers is not happening.
Problem is why have an RAF in the first place. Hugh Trenchard saw that bombing was that role. So bombing of Iraq in the 20s was not simply a mission but a role the RAF could fulfill.
We see this time and time again in all military great and small.
The RAF was independent. If it chased battleships then it's a glorified Naval air arm and if it bombed tanks then it's a glorified army support air arm.
The RAF must earn it's top table status by being able to do something unique and powerful.
Blowing up cities and winning wars singlehandedly is a good trick.
Then propose bombed up Gladiators.Expecting from RAF - where Bomber Command was the 1st violin - to just give away it's Blenheims and/or Battles to do the job of Army support is as real as the scenario where the IJN says 'well, the Decisive Battle concept is actually faulty, we better prepare for a long war with the USA'. Ie. a food for a what-if, but well divorced from what was going on in late 1930s.
But since this is what if sub-forum:
Battle as an army-support A/C is a dream come true for enemy AA gunners - big, slow, lacking armor and was unmaneuverable. Germans were fielding 20mm Flak by thousands already by 1938, a far cry what British and French had back then. RAF pilots flying bombed-up Gladiators will stand better chance.
Then propose bombed up Gladiators.
Yes, Battles as built lacked armor, they also lacked self sealing fuel tanks and had an engine that was good for 880hp at sea level, assuming you could open the throttle fully at under 200mph with the two pitch prop in high pitch (course).
It also carried 212 imp gallons of fuel which is totally un-needed for close range missions. Reducing the fuel tank size by 60 gallons gives you 450lbs to put into better protection without exceeding gross weight. Or pick even less fuel.
The Book shown above claims the Battle was more maneuverable than the Blenheim but gives no numbers or conditions. Rolling better than a Blenheim is certainly believable (still may not be true?) but horsing a Battle around in even a 60 degree 2 G bank turn is not going to last long without bleeding off speed. The Battle has a lower power to weight ratio than the Blenheim as built. Maintaining speed at low level with the Melrin III and a two pitch prop is certainly going to limit the Battles actual options for maneuvers.
Germans in 1940 were using a lot of twin MG 34s AA mounts and even single MG 34 mounts. Italians in the Desert didn't have a lot of 20mm guns (they had some) and their armored vehicles mounted a single 8mm machine gun for AA that used a 24 round box magazine. Japanese had what for AA in Burma?
Some people have claimed (that book might even claim it?) that the Battle could have been the western IL-2. I wouldn't go anywhere near that far but it certainly could have been massaged into something better without actually doing a lot of re-work, like asking for new wings or fuselages. 3rd crewman might very well have been left home for low level strikes freeing up another few hundred pounds.
Fly high enough so the low caliber flak is of no bother.
So I propose we cancel all level bombing bomber projects and really focus on dive bombing. I really see that as the future. Especially if we are getting out of strategic bombing.
A lot of people who ignored the lessons of WW I. That didn't require hindsight.
But which lessons of WW1 do you recognize and which ones do you ignore? The whole reason Germany succeeded against France in 1940 is because the Allies were expecting a repeat of 1914 on the ground which didn't happen. You're applying hindsight in expecting someone in the late-1930s to selectively apply the RIGHT lessons from the First World War.
The Martin mid upper turret developed for the B-26 was an excellent design that was also used on the B-24 (not the B-25 which was a Bendix design). The British thought very highly of it and replaced the FN mid upper on late model Lancasters (Most Mk VIIs and Mk Xs) and all Lincoln Mk Is.
Unfortunately one of the lessons that the RAF refused to learn from the Spanish civil war is that bombers need escorts.
By the way, the Germans did plan for and execute at least some semblance of a strategic bombing plan in 1940-41. They at least had bombs more suitable for destroying industrial buildings and they did have working electronic navigation systems, even if primitive. These navigation systems were not built in the time between the fall of France and the start of the BoB.
And this is the point I'm making, you are singling out of Britain is at the exclusion of every other air force and strategic plan that existed at the time, which would not have been able to have done any better. The B-18A demonstrated poorer performance than the Whitley V, it had a smaller bomb load and it was poorly defended. By the time WW2 breaks out in 1939 the USAAC is only just receiving the B-17B and only after a year of WW2 the B-17C introduced, with around 34 B-17Bs in service. The USAAC was in no position to be able to launch the kind of campaign that Bomber Command found itself dealing with.Not saying American B-18s would have done any better.
The Battle and Blenheim could not make credible attacks and yet Bomber command (and the RAF) did not allow them to be used on missions where they would be of some use to war effort even if not the effort to make the RAF the supreme service which seems to have been a higher priority of some RAF officers than defeating the Germans.
Well, the Hs 123 was metal covered at least so it was less flammableThe bombed-up Gladiator - even more so with an low-altitude Mercury version - is akin to the Hs 123, that some people believe it was next best thing after the canned beer (I don't believe that mantra, though). I'd suggest it anyway.
Problems here are that the Defiant only shows up in very small numbers in the Spring of 1940, one or two squadrons. Futz about with very many changes and you won't even get those.Battle will probably need Hercules in the nose for 1939-40, the low-altitude versions were 1st produced. Gives ~50% more power than Merlin III down low right from the bat. Not a wonder A/C, but surely beats Saro Lerwick in usability. Yes, far less fuel for duties in the continent are needed, that buys a lot of weight allowance needed for protection, extra MGs and ammo. Better defensive firepower is needed, in form of at least 2 MGs, if not the turret from Defiant.
Now about the Defiant - it is smaller than Battle, turret can be replaced with something that is less heavy & draggy, Merlin VIII in the nose, 4 .303s in the wing, bomb racks; not quite a full-blown fighter-bomber, but close enough.
True the Germans had the Best army AA of anybody in 1938-39 but it was a fraction of what it would be later. Germans also had 106 divisions to spread those AA guns over (plus fixed locations) and while not all divisions got the same outfit of guns (which were sometimes actually operated by Luftwaffe units attached to the Army division) the vast majority of the 20mm guns were the Flak 30 version which fired at around 280rpm cycle rate. The faster firing Flak 38 was just being introduced in 1939.The war against Germans is looming at horizon, not against Italians, let alone against Japan. German air defences are formidable against low-flying aircraft; eg. 6700 of 20 and 37mm light Flak pieces were available in Sept 1939.
Trying to turn the Battle into an IL-2 requires a bit too much rework. Of course if we take out the nose armor and shift the IFF radio then the addition of 600-1000lbs of armor fuselage becomes rather easy1500+ HP engine in the nose is the 1st task, when talking about Battle becoming an armoured attacker. OTOH, a 1500+ HP engine on a Hurricane or Spitfire might be a better investment.
Return the FAA to Admiralty control now instead of waiting until May 1939. This may, just may stop Specification O.8/38, navalised observation/fighter that became the Fulmar, first flying in Jan 1940. This is the best chance for an early Sea Hurricane.Sept 1938, Changes the RAF can make…
Likewise the Blenheim saw very little modification until rather late.
Given the problems Bomber Command had with accuracy as late as 1942, I think this will be an issue.
You see what you wish to see.Virtually every country's military did, this is the point I'm making, so why single out Britain? all I see is motivated bias.
Point here is that at least the Germans recognized the navigation and bomb aiming problem and did something about it. So ALL air forces were not doing the same thing as the British. British capability changed enormously in 3 1/2 to 4 years. Original statement still stands. In Sept of 1938 the British COULD NOT effectively attack Germany from English bases.Yes, based on pre-war objectives, but their leadership and concentration on medium bombers in large numbers was proven to be short of what was required for a drawn-out conflict. The Germans' miscast preconception of lightning strike invasions worked against less capable forces, but in a prolonged war of attrition, the failure of its strategy was revealed in 1940 - the country had neither the aircraft or the industry to maintain a sustained campaign. Let's also not forget that Germany could not have achieved it's objectives against Britain without invading Western Europe. British bombers could at least attack Germany from Britain.
The difference I am trying to point out is that other countries air forces, however good or bad they may have been, at least tried to support the army and navy while the RAF insisted it was not their job while (in 1938) being incapable of doing the job they claimed was their primary mission.And this is the point I'm making, you are singling out of Britain is at the exclusion of every other air force and strategic plan that existed at the time, which would not have been able to have done any better.

I seem to detect a bit of bias here myself. What I have been trying to say is that the Battle and Blenheim could not make credible 'strategic" attacks in 1938/39. They were thrown into making tactical attacks at the last minute in France and Blenheims were used later in the Mid East and Far East for tactical attacks.he Battle and Blenheim could make credible attacks, the problem was the means by which they were used and the environments they were used in and reading their histories should tell you this. During the Spanish Civil War, similar aircraft types in similar roles were used to effect, but the difference was the resistance that German forces put up against the aircraft. The concept of the single-engined day bomber was not unique to Britain, the USAAC had its own in the Curtiss Shrike, which would have suffered the same losses if used in the same fashion. The Japanese and the Italians also had the same types in service and the Breda 65 suffered the same fate against British forces in North Africa.
I believe a lot of my argument is based on what was known at the time in regards to the need for better aircraft for CC and/or the proper use of aircraft for anti-sub work. The data/information was there from WW I. The RAF had conducted quite a number of tactical bombing/strafing operations in WW I and built up a body of knowledge. It was quite dangerous and losses were high. But few WW I planes could make deep penetration raids. However the idea that trench strafing or raids 20-30 miles behind the lines could be done by unescorted bombers seems to have slipped by the WW I pilots/commanders. Escorts were pretty standard.Your entire argument is based on hindsight and knowing what you know so far removed from the situation as it unfolded before the war and in those first years.
I don't believe I have ever suggested leaving the Blenheim's on the Ground. Please tell me the post that says so.Let's also not forget that Blenheims were available in numbers so why leave them on the ground? Why not use them? Once aircraft like the Mosquito and availability of US types appear in numbers it could be replaced and it was. Let's not forget that when the Blenheim first appeared it was the fastest bomber in the world and it was faster than the frontline German fighter the He 51. In the mid 1930s, why would you not put it into service? Are you suggesting that the Air Ministry at the time should have not ordered Blenheims into production?

British capability changed enormously in 3 1/2 to 4 years. Original statement still stands. In Sept of 1938 the British COULD NOT effectively attack Germany from English bases.
In May of 1942 they staged the first 1000 bomber raid so obviously capabilities changed.

You are also confusing a single engine day strategic bomber with attack aircraft or tactical bombers
don't believe I have ever suggested leaving the Blenheim's on the Ground. Please tell me the post that says so.
What I believe I have said about the Blenheim is that the MK I with a range of 1000 miles would have extreme difficulty bombing the Ruhr with Belgium and Holland Neutral.
If the RAF wasn't going to provide support for the Army it might have been nice for the army to know this so they could have gone to war with something besides WW I relics for heavy artillery.
Problems here are that the Defiant only shows up in very small numbers in the Spring of 1940, one or two squadrons. Futz about with very many changes and you won't even get those.
You want to put guns in the wing you may have to move/modify fuel tanks.
Take the Battle as is, stick a gun in the wing that doesn't have one, or if you have enough guns, stick two in each wing. You already have the bomb cells and or bomb racks for light bombs? at least racks were added later. Forget the Hercules, it shows up too late. The last Lerwick (of 21) was finished in May of 1941.

The faster firing Flak 38 was just being introduced in 1939.
Your argument depends on the time warp theory.Speaking of seeing what you want to see, again, I have repeatedly said "except the Luftwaffe". So, when Hampdens and Whitleys flew to Berlin in 1940 and bombed the city, was that not bombing Germany? During the first few months of the war, beginning in September 1939 (the very first night of the war, in fact), Whitleys carried out long-range flights over German territory, admittedly they were carrying leaflets, but the type managed flights as far afield as Poland, so the type certainly had the range, so why could they not attack Germany, in your opinion? It should also be noted that German resistance to these flights was minimal and loss-rates were due to many things, but certainy not because of intensive German opposition, so again, I ask you, why could the RAF not bomb Germany?
And yet, strangely enough, the successors to the Battle had roughly half the range. Fairey P4/34 and Hawker Henley, The RAF changed theri minds and didn't use either but the "requirement" changed.The Battle was a "Single-Engine Day Bombing Aircraft", which is wording direct from its specification. Its role was the same as any day bomber role. The single-engined day bomber had been in service since the Great War, DH.4s, DH.9s, Hawker Harts and Hawker Hinds all served in the single-engined day bomber role. These aircraft were used in tactical and strategic roles.
That rather depends on the mission, doesn't it. Sending them on near suicidal missions has to be balanced against possible benefits. Dropping a bridge to prevent a river crossing might be a worthy goal to save thousands of troops. Running planes out of fuel and loosing crews because you are operating on the fringe of your range and have no allowance for a wind change just so you can claim you can bomb a certain city is pretty poor planning. Please look at a map and check some of the distances I have given. In 1938 it was just about 400 miles from England to the Ruhr. The edges of the Ruhr. The two main bombers (Battle and Blenheim I) had book ranges of 1000 miles. You have a one hour reserve to deal with use of higher than cruise power use in combat areas/engagements, head winds on trip back and navigation errors. Been over this several times now.Your accusatory tone regarding the use of Blenheims suggests otherwise, I simply asked the rhetorical question of what would you have them do with what they had. Did you expect them not to use what they had, even known the flaws they had?
Talk about skewed views. what part of the word "artillery" didn't you understand?Again, your perspective is skewed by your own particular views based on hindsight. Which WW1 relics are you specifically talking about? Were they using Sopwith Salamanders? How about Airco DH.4s? Maybe Sopwith Comic Trench Strafers? Please elaborate on what you are specifically referring to.
I have been stating that the RAF could not bomb Germany effectively in 1938.
I have been stating that the RAF could not bomb Germany effectively in 1938.
Many air forces used planes of similar performance to the DH.4s, DH.9s, Hawker Harts and Hawker Hinds because that is what the technology of the day would allow.
