aircraft/loadouts Bloch MB.151/2. Mid tier french fighter

[CaID 8,996]

 

i would like to suggest an excellent french fighter for the tier 3 who will fit just right at Br. 3.7/4.0

the Bloch Mb.151 and Mb.152, the only 2 produced fighter of the family Mb.150s

 

 

first lest start by the history prototype of the two suggested plane. the Mb.150

the design of the MB.150 started in 1934 when the french started the C1 programs (c=chasseur=fighter, 1 for the crew) the purpose of this program was to create a new fighter for the french airforce. the Mb.150 was designed by the engineer Maurice Roussel. the first aircraft was powered by Gnome et Rhône 14Kfs of 930hp and was armed by 2x 20mm Hispano-Suiza HS-404 on the wing shooting outside the propeller. the plane was built at Courbevoie 17 July 1936 and tested and proved to have a terrible design mistake to have a too small propeller to allow the fly. while the prototype was built and moving, it was unable to take off. the prototype was review in 1937 with the new designation of Mb.150

 

in the early 1937, the Mb.150 was redesigned with new reinforced wing of 15,4 M²  and new landing gear. the plane flew for the first time at Villacoublay the 4 may 1937 with a new Gnome et Rhône 14N-0 engine of 940hp.

while been tested, the plane saw other modification, the first was the new engine Gnome et Rhône 14N07 of 940hp. the modified Mb.150 was renamed the Mb.151-01M and was evaluated at the CEMA of Villacoublay and flew officially at the speed of 434 km/h in December 1937. the prototype was sent back at Courbevoie where it was once again modified to have another new engine, the Gnome et Rhône 14N-01 allowing a larger propeller.

the new plane was sent back to the CEMA and tested. the production modification was to be fitting again a new engine, the Gnome et Rhône 14N-21 of 1 030 Hp.

 

the plan V adopted by the Armée de l'aire was adopted the 15march 1938 and had the purpose the built 940 new fighter in 12 month for the french air force. the competitor couldn't fill the order that easily and the Mb.150 had a serious advantage to have the Engine in start shape allowing to be built by different company to meet the need of the production and fitting new upgrade. the Bloch company saw their industry nationalized by the french government into the SNCASO but wasn't including the development branch which allow bloch to still design new plane and modification. the Mb.150 was studied to fit different engine such as the Gnome et Rhône 14P, Hispano-Suiza 14AA and the American Pratt & Whitney twin Wasp which lead to the production of the new plane under the designation of Mb.151 and Mb.152

MB.151

the first order of the plane was put the 7 april 1938 for a pre-production of 25 plane based on the Mb.150-01 with the Gnome et Rhône 14N engine of 930hp. but the Mb.150 was rather built by hand and wasn't design for the mass production and couldn't meet the production requirement of the Plan V. the plane was completely redraw and saw a really fast redesign and production at Courbevoie with the engine Gnome et Rhône 14N-11 of 920Hp at 3 700m, the tail wheel was replaced by a ski  and the oil-cooling radiator was moved under the left wing. the armament was replaced by 4 7.5mm MAC 1934 with 300 round by guns. the new plane was called the Mb.151

 

the Mb.151 flew for the first time the 18 august 1938 but was clear during the test that the plane couldn't reach the required speed of 480km/h and wasn't very maneuable and couldn't dive well. the worse problem was the engine was overheating. in january 1939, 3 different radiator was tested before the Ferlay radiator was meeting the cooling requirement. all those issue delayed the production of the plane. the order of 144 MB.151 with 14N-35 of 920hp at 3 000m and 288 MB.152 was finally made in december 1938 while the production was delayed until march 1939.

 

The production of the plane was set at Châteauroux and 140 was planned. 90 for the Armée de l'aire, 25 for the Aéronaval and 25 for Greece, but the Aéronaval only received 16 plane and Greece 9 due to the War. by 10 may 1940, only 37 plane left in the Armée de l'aire because of their heavy lose in the Battle of France. while their heavy lose was clear, it wasn't due to the bad performance of the plane but rather by their intensive usage in the sky in the hardest battle.

Mb.152

the first frame of the Mb.152 was deliver at Courbevoie without engine and later fitting a Gnome et Rhône 14N-21 of 1030Hp and was planned to be armed by either 4x 7.5mm MAC mg or 2x 20mm 404 Cannon and 2x 7.5mm MAC mg and reach the speed of 520km/h at 5000m and flew for the first time at Villacoublay the 15 December 1938. after been sent back to Courbevoie, the plane was refitted with the Gnome et Rhône 14N-25 of 1 080Hp in January 1939 and like his brother, it was having the overheating tendancy limiting the speed at 470km/h. many combinaison of propeller and hood was tested to reduce the stress on the engine and the air-intake but finally a new air-intake behind the engine give the satisfaction of the plane. all those test delayed the production until may 1940

 

finally 144 Mb.152 with 14N-25 1 080hp engine and 144 Mb.152 with  14N-49 engine was ordered and generally armed with 2x mg and 2 cannon (as explained above) with most of them deliver.

I could've sworn I saw a picture of an MB.152 uploaded to the main site...in fact, here it is, or rather, a cropped screencap of a screencap that somebody uploaded on WT Live: https://live.warthunder.com/post/671933/en/

 

Don't know if it was removed or what.  At the very least it's safe to assume that at least that one's in the making.  Not sure about the MB.150 and MB.151 though.

i think the Mb 150 could be a good premium, the Mb.151 in the early tier 2 and Mb.152 in the tier 3 with the both engine in a tap line. then the M.157 come next.

 

on the side. the Mb.157 was made to be armed with the 2x 20mm and 4x 7.5mm at the same time. with the additional Mg, it should be at least at 4.0

yes it was suppose to have the 7.5mm, two for each wing with the 20mm, but the German captured it before it was completed. the plane was finished by the German but never armed.

nice. 3 more fighters for the french. it'll be nice to shift the almost entirely US-based french tier 4 towards something a little bit more native. +3

the US made a few plane with the french specification, like the H-75 A-1 to A-4. they are basically P-36 with french gun. they should be in the french tree too. with the Name H-75, the french gun and the french skin, most of the player will not actually notice they are not real french plane, and the American never used those one.

 

but those Mb.150 aren't fit for tier 4, more like tier 3 to me. maybe the Mb.157 can be tier 4 at BR.4.3, if they add the 7.5mm that should be there. the Mb.155 can also fit at Br.3.7 ot 4.0 but under 4.3, i think it shouldn't be tier 4.

 

but dont worry, i made a nice suggestion on a nice heavy fighter with many 20mm who cannot fit anywhere else than tier 4.

I don't know if this is the truth and if it has the consequences it implies, but it seems that recently, content for the Bloch 151/152 have been removed from files. Meaning They were perhaps considered at some point for the game but its not the case anymore. I hope I'm being too pessimistic here, because that would be terrible. After all, those were among the main forces of the French air force during WW2.

the 152 was in the file since the release of France. it was even announced in the french devblog but finally never came out. i am sure soon or late it will come out. the Mb.150s series is pretty much the back bone of the french aviation of WW2 along side with the D.520. Gaijin should stop looking to add more American plane in the french tree, add the Mb.150, 151, 152, 155 and add those LMG on the 157 as it should and it was confirmed  by Dassault aviation (ex-bloch aviation, who had actually that plane)

I really do hope you're right. Aside from the Corsair (which is a ground attack plane, as if we didn't have enough of those already), between the F86 and the copy pasted Leo, every plane in the French tech tree for 1.79 was a disapointment for me.

the french tree have so much penitential, not only in the planes but also in the grounds forces, personally i would add the D1 and D2 right away and take place of the reserve H-35. add the H-35 mod 1939 and put the H-35 and FCM.36 hidden as their gun are a real pain even for lowest level. the FCM.36 could be replaced in the tree by the AMX 38 (1938) or the R-40 or even the original Char B1. to make the rank 2 a bit more competitive, i would also add the Somua S.40, it was unfinished but the hull was finished and only the armament was missing.

 

for the planes, aside for the MB.150s in the middle rank. the rank 3 & 4 could be improved from the addition of the SE.100, Se.580 and Capra R40 which would provide so good french high rank fighter who can actually reach the same level as any other heavy fighter of the rank 3 or 4.

 

there is of course always something to add but those are what the french tree truly need to be really enjoyable and unique.

[Arghail 1,220]

I agree. I'm more of a low-mid tier air RB myself so I would love to see fighters like the Delanne C-10, the Dewoitine 551, 520Z, The LN 401 or the VG 39 bis.... There's so much potential for the French tree beyond a plane like an 8.0 F86 that is completely and utterly useless.

and it wasn't like the french didn't had some good light bomber to got there.

I'm really bothered that they removed the Bloch fighters but decided to keep the reskin F-84G. New content would be much nicer

So, as mentioned in the posts above, this was posted on WT-live back when 1.73 was around the corner :

 

 

Was that a plan from Gaijin to implement it in the British tech tree ? Was it cancelled ? Did Gaijin ever give an explanation for its absence from the actual game ?

The Mb 152 is incredibly resistant! The Mb 152 of Veniel has recieved 360 impacts of bullets (including more than 20 impacts of 20 mm shrapnel) and was still flying.

So, the Bloch 152 was once again datamined from the game for 1.85... But it's not on the dev server. That said, the AMX 10RC that was supposed to appear as well isn't here.

I'm approving this for the MB.150 and 151, they should also be added into the game.

 

+1

[Kasukaru 2,164]

Not only this, but the MB-150 should replace the MB-152 as a gift vehicle and the MB-152 should go into the normal tech tree. It's a shame that one of the most successful and used French planes of WWII isn't even in the tech tree, while the MB-157 which was at best an unarmed prototype is there. So +1 and please Gaijin, for once, do the right thing, admit you did it wrong the first time and make this right!

[Arghail 1,220]

Gaijin has refused every possible archives and arguments when it came to the armament for the Bloch 157, they will never make the Bloch 152 a researchable vehicle. We can still hope for the other Bloch to make an appearance, especially the Bloch 155 and even perhaps the 151, but otherwise, this whole story is just a giant mess.
