35 Megaton Titan II Warhead

RLBH

Probably a derivative of the B41 physics package

That would make sense as it was such an efficient weapon

that developed 25 megatons on just over 10,000 lbs.

Yes, it's actually the most efficient nuclear bomb we ever built.  It's design was quite creative

• Lithium Deuteride boosted primary
  
• Secondary lithium deuteride (fusion) secondary
  
• Tertiary lithium deuteride (fusion) tertiary stage (only one of it's type)
  
• Fast fission jacket
  

.

Around this time, it was reckoned that 100 megatons could be done with a B-52-carried weapon if testing was allowed - and SAC reckoned that it could be useful. 

From the statistics I remember reading in the article they said a 35 megaton warhead could be produced in a 3700 kg warhead, a 50-70 megaton warhead for B-52 use provided no testing was used (just current knowledge).  If testing was allowed they may very well have been able to do it: In fact, if the megaton/metric ton ratio stayed the same this would yield approximately the following

• 9.46 megatons/metric ton
  
• 3,700 kg/8,157.094 lb; Yield: 35 megatons
  
• 5,285.714 kg/11,652.99 lb; Yield: 50 megatons
  
• 7,400 kg/16,314.188 lb; Yield: 70 megatons
  
• 10,571.429 kg/23,305.983 lb: 100 megatons
  

Some of these would be within the practical load (~10,000 pounds) the B-52 could carry, and definitely within the maximum load (43,000 pounds)

• 4 x Nuclear Warheads with a maximum weight in the ballpark of 10,000 pounds (4 x B28?)
  
• 2 x W39: 12,460 - 12,800 lbs
  
• 1 x B53: 8,850 lbs
  
• 1 x Mk41: 10,611 lbs

What size blast would it take to shift the earth's orbit?

Now that would boggle the mind. Moving 10²⁴kg takes quite a few zeroes more than 100 MT.

Let me get this straight Lister, you're planning to play pool with planets?
