There is no urgent danger to Japan from a nuclear attack by Fat Boy.

オハイオ級の任務は、海中に潜み、アメリカ合衆国に対して核ミサイルが発射された場合、または発射される恐れがある場合に相手国に核ミサイルを発射することである。








Yes, Kim Jong Un allegedly likes to play with nukes, but even this whack job must recognize he has a small problem. Namely, North Korea has tested underground five tiny nuclear bombs so far (2006, 2009, 2013 and two in 2016). Yet none of them appear to have been even a “boosted” fission bomb, let alone a thermonuclear (fusion) warhead.

Indeed, the range of estimates put the latest explosion in September 2016 at about 10 kilotons or slightly smaller in size than the bomb dropped on Hiroshima in August 1945, code-named “Little Boy”.

Needless to say, Little Boy was not delivered by a sea-based or land-based intercontinental ballistic missile, and not just because neither had yet been invented!

In fact, it was dropped from bay of Enola Gay, a B-29 bomber, because, as is self-evident from the photo of Little Boy below, it was just an A-bomb, not an H-bomb. It was therefore way too big and bulky to fit in the nosecone of a missile, even if the US had possessed one.

That is, to miniaturize a nuke sufficiently to get its weight and size down to missile-riding scale, it needs to be a thermonuclear device.


In fact, what he has tested so far would have to be delivered by one of his 50-year old Soviet era Il-28/H-5 bombers, which amble in the sky at slow speeds and low altitudes and would be shot down by South Korean fighters or air defenses in a heartbeat. That is to say, at the moment the only thing the Fat Boy can actually vaporize is his own country.



But here’s another thing. Even after accounting for current treaty restrictions, one Trident submarine can carry 20 missiles with 8 warheads on each missile. That means just one of the Navy’s 14 Trident submarines can deliver 76,000 kilotons (160 warheads X 475Kt each) of nuclear payload.

That’s 4,000 times more than “Little Boy” delivered to Hiroshima in August 1945. And it’s also 4,000 times more than Fat Boy can deliver by slow bomber today!

In short, if the job is actually deterring Kim Jong Un’s nuclear fantasies, the whole matter could be handled by permitting the South Koreans to rent the services of one Trident submarine. And that could be done for far less than the $1 billion per year they are now paying to help defray the massive cost of the 29,000 US troops stationed there and the huge infrastructure required to support them in combat ready modalities. 


技術的なことがさっぱりわからないので、なんだか、なんだが、とにかく、現在、北朝鮮による核攻撃の心配はない、と。

 核実験成功しているんだけど、その規模はようやく広島原爆級。しかも水素爆弾じゃないから、小型化できない。
 でかいから、飛行機でやるしかないが、北朝鮮がもっているのは五十年前のソ連の戦闘機。ノロノロとそんなの飛んできても、韓国の戦闘機にすぐにやられてしまう、と。

 因みに、核ミサイルを搭載できる原子力潜水艦なら、広島級の原爆、つまり、北朝鮮の原爆の4000倍の核弾頭を積み込むことができる。

 北朝鮮の核に対する抑止力ならこれで十分で、戦略ミサイル原子力潜水艦に来てもらえば、その他の米軍なんていらず、安上がりに防衛できるのだ、と。

ーーーなのかもしれないが、いずれにせよ、北朝鮮が核の小型化、長距離ミサイル開発に成功する前に叩いておくことは重要。

 それと、日本も核ミサイル搭載可能な原子力潜水艦を製造すべきだな。
