US Modernizes Nuclear Arsenal With Smaller, Precision-Guided Atomic Weapons (nytimes.com)
HughPickens.com writes: The NY Times reports that the Pentagon has been developing the B61 Model 12, the nation's first precision-guided atom bomb. Adapted from an older weapon, the Model 12 was designed with problems like North Korea in mind: Its computer brain and four maneuverable fins let it zero in on deeply buried targets like testing tunnels and weapon sites and its yield can be dialed up or down depending on the target, to minimize collateral damage. The B61 Model 12 flight-tested last year in Nevada and is the first of five new warhead types planned as part of an atomic revitalization estimated to cost up to $1 trillion over three decades. As a family, the weapons and their delivery systems move toward the small, the stealthy and the precise.
And some say that's the problem. The Federation of American Scientists argues that the high accuracy and low destructive settings means military commanders might press to use the bomb in an attack, knowing the radioactive fallout and collateral damage would be limited. Increasing the accuracy also broadens the type of targets that the B61 can be used to attack. Some say that a new nuclear tipped cruise missile under development might sway a future president to contemplate "limited nuclear war." Worse yet, because the missile comes in nuclear and non-nuclear varieties, a foe under attack might assume the worst and overreact, initiating nuclear war. In a recent interview, General James Cartwright, a retired four-star general who last served as the eighth Vice Chairman of the Joint Chiefs of Staff says the overall modernization plan might change how military commanders looked at the risks of using nuclear weapons. "What if I bring real precision to these weapons?" says Cartwright. "Does it make them more usable? It could be."

Aren't fallout and collateral damage the main problems people have with nuclear weapons? Without those factors The Bomb wouldn't have that enormous stigma attached to it, it would be just another bomb, albeit larger. Since the Cold War is over, and since everyone involved knows that smaller tactical nukes exist, there's no reason that the response to any and all non-testing nuclear explosion has to be full-on empty the silos.
1) China and Russia are likely to do the same thing eventually. Russia in particular is pumping a lot of money into modernizing their nukes. Do we really want to end up having to catch up here?
2) This might make China and Russia less likely to start some crap if they fear that the US might nuke them in retaliation. There are a lot of countries that would be really happy if both China and Russia would calm down right now.
The FAS also claimed that more-precise weapons back in the 1970s, 1980s, and 1990s would cause nuclear war.
And that a missile defense system would cause nuclear war (except for the one the Soviets built and still use, of course).
Oddly enough, over the last half-century, none of the things the FAS said would increase the chances of a nuclear war actually caused a nuclear war. The things that nearly caused WWIII were things they never actually mentioned...
Aren't fallout and collateral damage the main problems people have with nuclear weapons?
No. The main problem is that they are weapons of mass destruction that can vaporize entire cities in an instant. They are weapons that are specifically designed to kill a large number of people over a large area very quickly. THAT is the main problem with them. Let's not lose sight of why nukes are scary. The fallout merely adds the problem.
The term collateral damage when applied to nukes is kind of meaningless. The entire point of a nuke is to destroy everything in a rather large radius. There really is no such thing as collateral damage when using explosions of that size because you are unavoidably and intentionally targeting non-combatants and infrastructure when you make the decision to use one. Yes this remains true for "tactical nukes" too.
We've had precision guided nuclear capable weapons systems for years.
Just to pick one ( since it was my particular specialty for years ): the Tomahawk Cruise Missile.
The Block III variant came in four fantastic standard flavors that could be ship, air and even sub-surface launched:
109A - Nuclear Tipped with a W-80 Warhead. Dial-a-yield of 5kt or 150kt. ( Google the W-80 for more info )
109B - Anti-ship flavor. Conventional warhead.
109C - Land-attack flavor. Conventional warhead.
109D - Land-attack flavor, sub-munitions dispensing warhead.
This is just the Tomahawk. I haven't kept up with the other cruise missile variants, gravity or guided smart-bombs, or even
the advances ( if any ) in the ballistic missile platforms.
So, I'm not entirely sure what all the fuss is about since we've had selective yield weapons since at least the late 70's.
Personally, since there is no putting the genie back in the bottle, I would prefer a much smaller yield high precision device
over the city-flattening strategic overkill ones that defined the Cold War era.
Folks may argue that the desire to use them would increase since they're not as terrible as their strategic brethren, but some
of these weapons are older than many of the folks reading this and have had this capability the entire time. Yet, we haven't been
tossing them around en-masse during our many, many conflicts around the world over the years. Unlikely we're going to start now.
It means you can get it down the entrance tunnel or ventilation shaft of that deep bunker before detonating - destroy the bunker with a smaller warhead than a ground level nuke would need to penetrate.
Considering even a small nuke would come in at a weight exceeding that of a 2000lb LGB, mass and penetration isnt an issue - and delayed fusing is a norm for most guided munitions these days...
The point about having a small nuke is that you can take out that deep bunker with much less collateral damage - the deeper and better protected the bunker, the bigger bang you need at the surface, which means more collateral damage. Put the nuke down the ventilation shaft or down the entrance tunnel and you suddenly need much less bang as you are penetrating much less overburden.
Its the same reason you needed a 20,000lb earthquake bomb in WW2 to take out targets we hit with a 250lb guided munition today.
And I have no idea what you are talking about regarding wifi.
