The B61 Mod 12 Life Extension Program will consolidate Modifications 3, 4, 7 and 10 into a single modification (B61-12) while extending the system's service life.
可見B61-12是取代B61-3，B61-4，B61-7，B61-10這幾個型號。
為什麼不包含B61-11。
是因為B61-11與其他子型號差別較大，比如氣動，重量等，導致無法相容？
還是因為B61-11是鑽地型號，也較新，不需要延壽，也不需要較高精度？
還是純粹是因為缺錢？
B61-12的制導套件，價包含慣性制導，價格卻很貴，什麼原因。
即使是扣除研發後的生產價格，也是幾十萬美元一套，遠遠超過其他類似產品，比如JDAM。
軍用INS制導部件其實是量產貨，很多產品都會用到。
如果B61-12因為核輻射問題，不能使用通常的INS部件？
核輻射有這麼難以解決麼。
那麼冷戰時期，那麼多核條件下的INS是怎麼解決的？
還是說要麼不解決，比如以前的B61，根本不制導？或者不計成本？ |

鑽地型號的技術問題可以比對一些水壩炸彈之類,以及核砲彈或導向砲彈,因為起爆前要忍耐一段時間的衝擊,而不是可能空爆不會在事先承受太大應力的一般核彈,極度要求裝備精密度的核融合機制幾乎無法使用,多用分裂機制,內部有太多不同之處.
另外,有融合機能的型號,融合材料半衰期大概10~20年,分裂材料半衰期,鈾可是45億年,鈽239也有2.4萬年,融合彈會比較需要早一點處裡融合物質問題. |

你的回答，只能說明不延壽的原因。
這個原因我也提到了。
但是B61-12計畫包括2個部分，核彈頭延壽，以及加裝制導系統。
為什麼不加裝制導系統？ |

最新一期的軍事連線有講到這個!!
就我在看到的解釋是,
B61-11是戰略型核彈,
B61-12是戰術型核彈,
換言之,
是使用的目的不同........
青干難斷,塵緣易了,下山去吧!!

依照简氏航空武器年鉴《B61 nuclear bomb》里所说：
Platforms
The B61 was employed as a tactical and strategic weapon to replace the Mk 28 and Mk 43 bombs in the US inventory. Following the cancellation of the B77 programme in the late 1970s, the service life of the B61 was considerably extended.
The B61 had a long service life and was qualified for carriage on the A-4, A-6, A-7, and F/A-18 of the USN and USMC, along with the F-100, F-104, F-105, F-4, F-15E, F-16, F-111, and B-52H of the USAF.
The existing in-service B61 is carried by just four US aircraft -- the B-2A, B-52H, F-15E, and F-16C.
The lower-yield weapons such as the B61-3 and B61-4 were allocated to the USAF and NATO tactical fighter bombers, such as the F-15E, F-16C, and Tornado.
The higher-yield B61-7 and B61-11 are deployed only with USAF B-2A and B-52H bombers.
The B61-12 (B61 LEP) intends to be equipped onto the B-2A, F-15E, F-16C/D, F-16 MLU, F-35, PA-200, and NATO aircraft as well as the next-generation B-21 bomber.
The B61-11 specialist penetrating weapon was not included in the LEP as it was felt to be sufficiently modern to remain in service without change.
而简氏战略武器年鉴则提到：Various reports suggest the bomb has a number of separate and selectable yields; three strategic yields between 100 and 350 kT; a strategic yield in the region of 80 to 150 kT; a tactical low-yield (10 kT) option; dial-a-yield technology of 0.3 to 340 kT (as noted above); and selectable yields on the Mod 3, 4, and 10 bombs (between 0.5 and 45 kT) and on the Mod 11 weapon (between 0.3 and 350 kT).
也提到了2009年完成的Mod 7和Mod 11的升级。 |

B61-12
最大差異
鑽地+導引+安全+可變威力
400枚造價就110億美元=2750萬美元/枚
