Walt, you are close enough on most answers so I can't deny you and ask for more. Congrats! My answers from the database of Robert S. Dudley with Walter J. Boyne:

1a. "Czar Bomba", 1b. 58 megatons.

2a. Tupolev Design Bureau, 2b. Tupolev, 2c. Tupolev Tu-95 strategic bomber, 2d. NATO reporting name: "BEAR"

3. I only have 1961, yours exact!

4. The four Kuznetskov turboprops have two, counter-rotating props, four blades each-eight propeller blades per engine, the blade tips of which move supersonic, hence the huge noise the aircraft made in flight. (Pretty big air slicers and dicers!)-32 props total per aircraft!

5. The Tu-95 could and did experimentally carry and air-launch a Mikoyan-Gurevich MIG-19, a supersonic (in level flight) JET AIRCRAFT- NATO reporting name: "FARMER", designated by China-license-built as the Shenyang J-6.

The Tupolev Tu-95 was conceived as a best compromise bomber between speed, fuel-consumption and range; prototype flying on 12 November 1952. The design is expected to fly active in service until 2040, maybe beyond! It can make Mach 0.8. An unusual aspect is the 35 degree swept wings on a prop aircraft. Many versions of the Tu-95 bomber have been built. The maritime patrol, recon, anti-sub versions are the Tu-142, also "BEAR". Production was from 1952-1994. It is the only prop-powered strategic bomber still operating.
