I mean, if a full internal load flexed the fuselage that much that the canopy jammed open if it wasn’t closed before loading, then surely something must be wrong with the design?

lol, that was a harsh age for the aviation 😀

Probably had to do with the bomb bay and how was it designed, wonder if somebody has a structural schematic of it.

It was simply an obsolete airframe.

I don’t really think in that way, depends on is what is defined as ‘obsolete’, is the B-52 obsolete?, is old is a really old design, but still working, same for the Tu-95.

Yes the yak is not in service anymore, but that airframe was so heavily used in so many task, and performance ranges, that i hardly would classify it as ‘obsolete’, at least in the 60’s, it had not bad performances either, it was probably the best configuration for the 60’s technology, all the other planes finished heavier, the f-105, the f-101, all them with 4-3 tons more.

But is was ugly, yes that’s for sure 🙂

but I can assure you that it’s a very cramped cockpit. The view forward through that cool windshield isn’t all that great either.

Would like to see them, wonder if the pilot had the ‘windshield guy’ lol, on sight.

Wonder if was actually a co-pilot there..i mean a seat or something like that?

More pictures, for the trolls 😀

great plane

Thank you!

Air breaks?

Another interesting thing is the Su-25’s long engine pods, much like the Yak-28’s ones, there is a special flow requirement for this engine’s family? or is just a coincidence?, i can understand the yak needed it for the high Mach requirement and the movable inlet, for the su-25 there is probably other reason..

It was not a success.

This happens when you try to convert a multirole airframe into a specialized airframe

What is interesting is that the designers went from that engine configuration to the classical yak configuration in the yak-45.

This is really interesting, why did Yak left the side by side engine configuration for the su-15 contest? why did they return with the typical wing mounted engine for the yak-45?

f-105

mach 2 with 13 tons weight, 1200km radius

vs

mach 1.8 with 10 tons weight, 1200km radius

big deal, i had rather go with the lighter airframe.

14-13 tons was the weight equipped (with fuel)

Surely the supersonic Canberra was the Tornado?

Too heavy, too complicated, too fancy for that title 🙂

One fun thing i can see on this plane is the variety of the nose windows design

The max speed of the yak-28s fitted with afterburners was M1.8, quite good, was clear the design was optimized for both, transonic and supersonic speed, the engine pods under the wings was another interesting idea, mostly used for civilian planes for easy access on the engine for better maintenance, this is a interesting requirement for a CAS aircraft, while the yak-28 was most likely less tougher than the Su-25, probably a further design based on it had performed better, both engines are very separated, this could be an advantage, since the probability that both would be hit at once had to be low, remains to be seen how simpler and reliable the controls were.

More/less the same configuration was used for the Yak-45, a plane that was in competition with the Mig-29, even the same landing gear configuration, is interesting how Yak was so confident in this design.

The bloke in the nose became superfluous with improved avionics.

I disagree, a special crew trained for CAS would be welcome to recognize and classify targets, CAS is a nasty job, and many times high tech gizmos are useless compared with a guy with night vision goggles.

The Su-24 took over the longer-range strike role.

The fencer is other class of aircraft

More online pictures, waiting for some pictures from the inside.

Damn sexy plane, the tail controls were very small, it seems.
