Il2 DD Update Dev Blog 238 "Yak-9 & Yak-9T"

Recommended Posts

Hello everybody,

 

This week we continue telling you about the new Collector Planes, now is the turn of Yak-9 and Yak-9T. Yak-9 was the most mass-produced Soviet WWII fighter, more than 14,000 were made on three factories in Moscow, Omsk and Novosibirsk in total. The production started during Autumn 1942 and peaked in 1944, but continued well after the war ended - it stopped only in 1948. They were used in combat en masse for the first time during Kursk battle in Summer 1943, but several documents reflect smaller scale combat deployments of the new fighters on other fronts of 1943, including the Battle of Kuban.

 

Yak-9, while being an evolution of Yak-7 design, had significant changes: metallic spars instead of the wooden ones, bubble canopy with an improved field of view, forward-and backward-facing armored glass pieces. The fighter armament was standard - 12.7 mm UBS MG and 20 mm ShVAK gun. It was powered by M-105PF inline engine.

 

We also recreate a special model of this fighter, Yak-9T, that was developed to counter enemy bombers and was also used against lightly armored targets. A powerful 37 mm NS-37 gun with 30 rounds ammo reserve required more space, so the pilot's cockpit has been moved back to make more room for it and to maintain the pitch balance. It's interesting to note that while this gun was much more powerful, the total weight increase was just 40 kg and the plane aerodynamics did not change for the worse noticeably.

 

We'll start the work on Yak-9T immediately after finishing Yak-9 (the exterior 3D model of Yak-9 is nearly complete while its cockpit 3D model and physical model are in the works and show good progress).

      Attention Pilots!

      Update 4.006 will probably be released on Tuesday May 19th (tomorrow) if all goes well. If not, we'll try again on Wednesday. So back up anything you want backed up before you attempt the update. This will be a big one, maybe backup your entire IL-2 install folder just in case. Update servers will likely be jammed for a while so please have a bit of patience with us. This update is JAM PACKED with good stuff. We think you'll like it a lot. 

      Also, I will leave the Yak-9 and Yak-9T Pre-Order discount live for a few more days, but hurry it will end soon! These Yaks are worth every penny. A lot of fun!  

      Buy Here!

      Some great skins for the Yak-9 are included.


      Finally a Soviet fighter with good performance and a 37mm punch! 



      Sizzler!

      Dear friends,
      Update 4.006 will be released soon and we can show you more of the coming improvements. Today we'd like to demonstrate how the aircraft materials and textures will look in the new renderer compared to the old one. For instance let's look at La-5 series 8, He 111 H-6, P-38J-25, Albatros D.Va:
       





      We also have good news about the changes in 4.006. First, the airframe damage model for the WWI planes will be tuned according to your feedback. Second, the ships in the sim will have more advanced physical models - they will be able to run aground, receive an impulse from collisions, etc. - this is important for the Battle of Normandy where they played a major role. Third, according to Tank Crew players' feedback, we added a server option to disable tank AI gunners in multiplayer. Another option that has been requested for a while - now tech chat messages are a difficulty option so the players will be on equal terms in multiplayer.
       
      Our engineering department improved the FM and systems modeling for a number of planes, including Yak-7 and Bf-110. Tank Crew assault guns will be able to fire indirectly at a heading and distance set by the gun or platoon commander. In the graphics department, we're adding an alternative antialiasing method, FXAA, which trades some AA quality for a noticeable performance boost. It also has a side effect of somewhat improving the visibility of the contacts against the ground, especially when used in conjunction with the "Sharpen" graphics option. Several planes from already released modules will get the 4K quality external textures and the rivers and sea will get the updated water surface visualization.
       
      As usual, the full list of the changes and improvements will be available at the update launch and it is already close to 70 items total. We're hoping that the next update will be another step forward in the development of the project and you, our customers, will enjoy it. And to finish today's Dev Blog, here are a couple of Yak-9 and Yak-9T Collector Planes screenshots from our Producer:

      Dear friends!
       
      We would like to congratulate you on the very important holiday - 75th Anniversary of the Victory in Europe! On this day 75 years ago the hard and long road to peace, that cost millions of lives, has finally come to its end at the European theater of the world war. The people of all nations got a second chance to live. Let's remember the heroic deeds of our ancestors and be thankful to them - even though that today's crisis and problems are significant, they can't be compared to the gravity of the situation and the hardships of those years of war.
       

       
      The life that was given to us by the heroic deed of our ancestors continues. Coincidentally, this is a small anniversary for our project, which is entirely dedicated to the World War II events, as well - you're reading its 250th Developers Blog. Our work on the sim also continues - in 2 or 3 weeks we plan to release the next update 4.006. It will bring not only the new player controllable machines - Yak-9 and Yak-9T Collector Planes and SU-152 assault gun for Tank Crew - but also the fundamental changes in the graphics engine: the renderer will be switched to Deferred Shading. At the moment this update is already in the beta testing and our team is working on debugging and finalizing it. The changelist will be a long one once again, it already includes more than 50 changes in different areas of the sim. To illustrate what these renderer changes add to the visuals, we want to show you the in-game screenshots of Yak-9T, which is a good aircraft to display the new graphical capabilities:
       



       
      Another pic we want to show you the WIP model of the early war German pilot which will be used in BoM, BoS and BoK timeframes. It's going to appear in the project a bit later, but it won't be a long wait:
