Sukhoi T-4: Russia's Mach 3 Bomber
Source: Wings of Fame Volume 7 (1997) p. 134


This is the bomber that everybody calls Russia's baby B-70 clone. It
featured similar Mach 3 high altitude performance, but was a bit
smaller with F-111 medium bomber range of about 4000 miles, and a two
man crew. It features a delta wing with canard, and four engines in a
squarish triangular section under the wing just like a B-70. It had
an anti-shipping missle purpose designed for it, but never went into
service. It has a dropping nose for landing with zero forward
visibility when it is up (there are four small windows that look up,
but evidently no side windows)


It was designed about 1963, when the B-70 was nearly complete. but
didn't fly until 1972. It lost out for production in favor of the
backfire medium bomber.
