=Wait till you see Tu-160 a complete copy of B1-B made possible by Putin's colleagues =
Most likely it is impossible, because both aircrafts are under military secret. Let's compare Russian steam locomotives which certainly were duplicated from American.. it will flatter yours American vanity much more.

The Tu-160 definitely has a lot of resemblance to the B1-B, but there are also substantial differences. Basically, the Russians made the Tu-160 bigger and faster than the B-1B. Some points of comparison:

Engine thrust per engine: 30,000lbs (B1B) vs 55,000lbs (Tu160)

Gross takeoff weight, max: 477,000lbs (B1B) vs 600,000lbs (Tu160)

Wingspan (extended): 137ft (B1B) vs 182ft (Tu160)

Length: 146ft (B1B) vs 178ft (Tu160)

Speed: 900mph (B1B**) vs 1400mph (Tu160)

Unrefueled ranges and internal bomb loads end up being similar, though.

**The B1A had a top speed of ~1450mph at 50,000ft. This feature was removed in the B1B production model.

The Tu160 and the B1B are rather like the Buran and US shuttle: strikingly similar on the surface, but with significant differences under the hood. The Tu160 definitely isn't a rivet-for-rivet copy of American hardware like the Tu4 Bull.
