The T-90 is a souped up T-72. Modern T-72 variants use the same V-92S2F engine as the T-90 variants. There is a huge degree of commonality between both tanks. The main difference is the turret.

It isn't, though. It might have started life as such but later on they became different tanks. You would call an M60 the same as an M47. Hull armor layout and other things are different from the T-72 to T-90 which is what allows the T-90M to take the longer 3BM60 rounds than the T-72B3M cannot.

But wait then we have the T80 which has a completely different automatic loader and all the other components are different as it was designed in Ukraine by a completely different manufacturer.

Common misconception on the basis of the T-80's being an extension of the hi tech-lo tech mix trend of T-64/T-62. The T-80 is a Russian design, made from the ground up by Leningrad Kirov Plant and that at some point the Soviet Union made Kharkov produce the UD variant.

SDA Tranche 0 hypersonic tracking test next week
Please, Log in or Register to view URLs content!

L3Harris Ad for hypersonic tracking layer, progress so far:
  • Completing our first IR sensor unit, as well as a Ground Readiness Review and System Readiness Review, for the SDA’s Tranche 1 Tracking Layer program.
  • Completing System Requirements Review and System Design Review for the SDA’s Tranche 2 Tracking Layer program.
  • Completing Critical Design Review on the IR sensor payload for the SSC’s MTC Epoch 1 satellite constellation.
To meet current and future customer needs, we’re also investing heavily in scaling operations, with a focus on physical, process and personnel. Plans include building a new 60,000-square-foot IR sensor production facility in Indiana, with capacity to support the assembly, integration and testing of sensors; as well as a 90,000-square-foot space vehicle integration facility in Florida that will double L3Harris’ capacity to integrate and test satellites.

What a load of baloney. The F-22s and F-15s are rotting away. They are having to buy the F-15EX, a warmed over 1970s aircraft, and they are still considering if they need a modern heavy fighter or not. Yeah right. China already has more modern J-20s and J-16s than the US has F-22s and F-15s.

The Sentinel ICBM and the Columbia submarines are eating the budget.

The US clearly needs to make deep cuts in several areas and change its force structure. But further delaying the heavy fighter program is not the way to do it.

F22 is in cycle for its upgrade and reset. Its still ahead of the game vs any other comers and not likely to be matched for sometime.
F15EX is as the F15 fleet is in decline that’s true it’s what happens when you fly the wings off of a machine at flight hours rates that would stupefy the next air forces . however it’s a 1980s base heavily modified in the 1990s then father modernized in the 2010s… hmm sounds like Su35 and Mig 35?

Sentinel ICBM budget projections are high but not as many are making them out to be. We will spend as much on High speed rail in the American southwest.
Columbia class hasn’t broken the budget yet and we have other projects.

Maybe they will not retire f22 in 2030 like planned. The number they have presently and will have in 5+ years is so small that it will become very costly to maintain, they will cut and cut airframe for spare parts until it become irrelevant and it will be sooner than later.

The Su-27 design is a decade younger than the F-15 design. Su-27 has relaxed stability while F-15 does not for example.
Even then Western commentators often joke as if it is an obsolete design.

The Su-35 has lots of modifications made to the airframe to improve it. It uses more composites in the airframe to decrease its radar signature for example. It stores fuel inside the vertical tail fins to increase range. The original Su-27 can carry 9.4 metric tons of fuel internally, and the Su-35 can carry 11.5 metric tons. 22% more fuel. The Su-35 also has much more fuel efficient engines than the Su-27.

The F-22 in its original configuration is clearly behind both the Su-57 and J-20 in most parameters with the exception of the engine. It lacks the IRST, it has onboard computers that are two decades older, it uses older 1st generation GaA AESA radar technology, while Su-57 and J-20 use 2nd generation one.

The upgrades are supposed to add an IRST and HMD. While that should help it needs a complete change of sensors including radar and avionics and those do not seem to be happening at all. Meanwhile the size of the fleet keeps shrinking.

SU27s first flight was 1977 F15s was 1972.
So they are both 70s designs.

F15E changed the design to use lighter and stronger materials including both Titanium and composites but neither Su35 or F15E can achieve major RCS reductions based on these as they weren’t designed to be Stealthy those huge vertical tails are a Giant kick me sign on radar and the open inlets light up a X band return like Vegas.
Farther the F15EX received a new set of wings complete overhaul of its control systems moving to fly by wire and the latest radar technology.


The F-22 in its original configuration
Still has a significantly lower RCS and the effectiveness of the IRST in this capability has yet to be proven as enough to counter that.
J20 is a threat and that’s why NGAD/PCA is a thing. SU57 isn’t a thing yet. 22 SU57 isn’t a threat by the time it is F22 will have completed its midlife.
The MLD is slated to include radar upgrades however the Radar has undergone a number of modifications over the years already. Including back feeding technology form the AN/APG 81 from
The F35 array into the An/APG 77 as part of the V1. Electronic warfare system upgrades and the Avionics are slated for replacing as the U.S.A.F. Includes a change to a new open systems architecture operating system.

Lol, no.

Face it, and stop coping, it's a 90s planes with maybe some 00s stuff in it at most.

And while, yes, still a 5th gen plane, but the 'ahead of the game vs any competitor' is really lol.

Ok, wanna bet that their prices will not increase?
