What a/c are you referring to? The Tu-128 Fiddler interceptor or the
Tu-22 Blinder bomber (both based on the failed Tu-98 Backfin)?

Tysbin had its own design based on the NM-1- the RSR:

Thanks...
IIRC the Ruskies built something similiar to
the XB70 though smaller, I'm sorry I couldn't
find an online ref. and it was obviously not
deployed, it may be rumor. I'll reiterate,
"may have had something better".

That was the Su-100, a.k.a. "T-4":

Thanks for ref Rob. Claims the T-4 had
4 x 35,000# engines = 140,000#

-B-58 had 4x15000# = 60,000
-B-70 6x28000# = 168,000

I don't understand the rationale for the T-4,
in the time frame of the early 70's, if that's
true, except perhaps as an X-plane. If so
the T-4 would be quite more advanced than
the B-70 or SR71, with a burst speed well
over 2000mph, given the airframe and engines
and considering the Ruskies new alot about
Mach 3 ducting as the Mig 25 demo'd, it's
probably secret.

I also had in mind the "Bounder"
http://www.fas.org/nuke/guide/russia/bomber/m-50.htm
contemporary with the B-58,
M-50,52 total thrust = 112,000#, and more than
likely as fast or faster than the B-58.

Hmmm, T-4 bears some superficial resemblance, though it apparenly lacks
the VG wing-tips and double fin, is smaller and never demonstrated
quite as high a speed. I've never heard "compression left" directly
associated with the T-4, so if anybody has, I'd love to hear it.

Looks like "compression lift" at the front part
of the engine pod. The way the pod expands
it would produce pressure and compression.

And don't ge me started about that nose-droop thing.

I think that's neat, converts the wind-screen
into an air speed brake.

The B-70 used some
kind of motorized wing-screen which always seemed more preferable to
the big pivoting nose on T-4 which seemed more aesthetically and
functionally appealing. Does anybody know what T-4's operating
altitude was? Or its mission? I heard that T-4 was designed to strike
at enemy warships in waters along the Russian frontier, as opposed to
the B-70's strategic strike mission. From the stories floating around
the net, it appears that the T-4 was less a Soviet weapon to be used
against the West than one to be used by Sukhoi against Tupolev, hinting
that Russian aerospace was probably inundated with all sorts of
warplanes and making it inevitable that one looking somewhat like one
of our own would emerge.

One could argue the F-15 is a copy of the Mig-25.

In response, the US would have used the XF-108 Rapier as a B-70 escort:

...which is confirmed by everybody else, including WPAFB website, but
I've always been skeptical of that given what I've read in Anderson's
"To Fly and Fight". While describing his work on the parasite fighter
program, he remarks on SAC's traditional aversion to escorts - noting
that bomber pros claim that they can go it alone and then pay the price
when that proves optimistic. (Anderson gave the Korean experience for
B-29's as an example.) Seems to me that the USAF requested the B-70 to
have high-speed/-alt performance in order to obviate the need for an
escort. So why the F-108?

I see the F-108 as a parallel to the CF-105 Arrow,
which in a nutshell, were obsoleted by Sputnik,
and SAM's. Obvoiusly the manufacturer would
float any reason to keep the project, that's their
job.
