You’re joking right? Surface finish on that thing looked like it was slammed together by a bunch of HVAC installers.

no im not ,it was a prototype final product would be less visible to radar.;)
and besides welding was done pretty fast to meet leadership expectations,..our welders work for free -they were mostly liberated from gulags at that time,when Nikita came to power…:rolleyes::D

Here is a nice picture of a t-4 model…

it was the thing that conviced airforce to give funding to real prototype.

now some from engine testing with lower fueselage :cool:.

now that enabled internal bays to be checked for any exess of vibration
and launchers for overload fitted with missiles dummy weights, tail flight controls checks ets…
engine and internal bay -that was first part of aircraft finished ,usually in aircraft it was and still is- otherwise…

planes body was tubular design, was to be mass produced from cells ,some containing fuel ,some electronics ,some crew :D….

Adding nickel doesn’t displace the chromium. You add nickel to create a crystalline matrix that both stiffens the material and removes its magnetic characteristics. At the expense of stiffening the material you lose the ability to resist fatigue. Flexible material is usually less prone to fatigue for this reason. It is not always the case, obviously, and a materials characteristics do change somewhat as the material gets excited by heat. If you are going to use high nickel content in your stainless on an airplane then you are probably not using it for the framework.

you forget that nickel is much more resistant to atmospheric conditions then chrome it displaces, but Vanadium is there as a donor to make hexagonal into a cubic cristal structure of austenit type cold pressed steel, hard yet tough not brittle.
i ve guessed youve heard of invar-steel 35-37% Ni ,it was used same as a platinium for measurments ethalons ,-it doesnt streach with heat.
chrome is there to make steel resistant to breaking off molecules or as they say friction wear and tear ,but it reduces steel ability to be forged especially if its with 1,3-1,7 carbon,something nickel is positive to.
anyways combied chrome and nickel make good combination ,they both add hardness and stiffness to steel, but they differ in some aspects,so they are used mostly together as Chrome-Nickel Steel.

AM-350 is a fairly dated concoction. Stainless just refers to carbon steel doped with at least 1/9th (approx. 11%) chromium by content. You can alloy steel with all sorts of metals to vary its properties, including giving it more flexibility or less. However, you are not modifying its heat characteristics in a significant way. Titanium’s flexibility can also be modified in the same way, but it is lighter and holds its form under more adverse conditions. Stainless is better in one way, as it self heals when corroding. Unfortunately its characteristics when subjected to corrosion has little to do with its flexibility.

nickel is cheaper and can subsitute chrome up to certain percentages so stainless chrome-nickel stainless steel was used (with 0,5% vanadium.).
to all who say foxbat couldnt be manufactured with titanium because of bad technology ,lack off material ,whatever…just take alook at T-4

ok about the colour
top is titanium
titan+steel
steel
radio-transparent materials

it will be at some point depending on the growing capability of tehnology and funding and will in u.s.a.
the shield is getiing stronger dates are not as important but some say about 90% at 2050 with this growth ,too bad economy will get possibly very low and also 2nd superpower status at that time ,so this may convinse leadership to a calculated and /or acceptible risk of a first strike…

Question: With the advancement of the YAL-1A ABL aircraft, ground-based lasers, the obvious new ventures into space warfare beacause of the Chinese prompted space race and the advancement of railgun technology, will North America be impenetrable to ICBM strikes by 2020/25 when these technologies will be implemented into our operational defense forces? With a fleet of ABL aircraft, kilsats, railgun sats and ships and ground based lasers placed all over the U.S., I would like to think so, but I would like to hear some experts opinions on this matter…

they are all imperfect solutions ,however all together combined have very high chanse to stop incoming nuclear payload ,im affraid american will try to use this in future when these technologies keep steadily improving and finally mature…
for now for the begining its still not good enough but it will be….
when? well its hard to tell depend on technologies advance and lots of it is secret it makes us dry our budget for espionage purposes since nuclear and anti-nuclear technology was and is our number 1 priority…
the only thing now stopping them from anihilating us are our huge stocks of longrange cruise missiles and little bit our poore submarine fleet.

what a nice thread…

Until now no new Su-35 has been flown. They test some of the technologies in the Su-27M and Su-30MK2, not more not less.
No one speaks about unbeatable, just that it isn’t that easy as you suggest and that a lot of details are unknown.

The KS-172S-1 is not operational, let alone that it is more optimised for less manoeuvrable targets like tankers or AWACS.

maybe you misunderstand me as i was talking about engines and some other systems they arent su-27 m,mks anymore but supercruising, irbis testing ,
KS[172nautical miles] missile firing aircraft.
KS has been fired away thanks to vympels seeker help to novator.
