Daya ledak senjata nuklir: Perbedaan antara revisi

* Senjata nuklir taktis [[Davy Crockett (senjata nuklir)|Davy Crockett]]: 0,01–1 kt — berat hanya 23  kg, senjata nuklir teringan yang pernah dibuat oleh Amerika Serikat (hulu ledak yang sama dengan ''[[Special Atomic Demolition Munition]]'' dan [[AIM-26 Falcon]]).

* ''[[Ivy King]]'': 500 kt — bom fisi murni terkuat; 60  kg uranium; ''implosion type''.

* EC17/Mk-17, EC24/Mk-24, dan B41 (Mk-41) (senjata terkuat AS: 25 Mt; Mk-17 juga merupakan yang terbesar dalam ukuran dan berat: 20 ton; Mk-41 memiliki berat 4.800  kg; bom gravitasi yang dibawa oleh pesawat pembom [[B-36]] (dinonaktifkan pada 1957).

Sebagai perbandingan, [[pembomanpengeboman kota Oklahoma]] yang menggunakan sebuah truk hanya sekitar 0,002 kt.

Rasio daya ledak terhadap berat adalah besaran daya ledak dibandingkan dengan berat senjata. Rasio maksimum teoritis daya ledak terhadap berat untuk senjata fusi adalah 6 Megaton per metrik ton (6 Mt/t). [http://nuclearweaponarchive.org/Usa/Weapons/B41.html] Batas yang dapat dicapai dalam praktik lebih rendah. Untuk senjata AS sekarang adalah 600 kt/t (2,5 TJ/kg) sampai 2,2 Mt/t (9,2 TJ/kg). Untuk perbandingan, rasio untuk [[Davy Crockett (senjata nuklir)|Davy Crockett]] adalah 0,4 - 40 kt/t (0,002 - 0,167 TJ/kg), untuk [[Little Boy]] 4 kt/t, dan untuk [[Tsar Bomba]] 2 Mt/t (8 TJ/kg) (dikurangi secara sengaja dari daya ledak maksimum yang dimungkinkan dimana merupakan dua kali lipatnya) dan untuk Mk-41 5,2 Mt/t.

Bom fisi murni yang pernah dibuat memiliki daya ledak sebesar 500 kt, dimana kemungkinan hampir mencapai batas maksimum disainnya. <!--Fusion boosting could likely raise the efficiency of such a weapon significantly, but eventually all fission-based weapons have an upper yield due to the difficulties of dealing with large [[critical mass]]es. -->Belum ada batas maksimum yang diketahui untuk bom fusi seperti hidrogen. Secara prinsipil sebuah bom fusi dapat mencapai ribuan megaton.

Untuk operasional, berlaku batas maksimum dalam pengiriman lewat udara. Contohnya, jika maksimum daya angkut sebuah [[Antonov An-225]] sebesar 250 ton dapat digunakan, maka batas maksimumnya adalah 250 t * 5,2 Mt/t atau 1.300 Mt. Batasan serupa juga berlaku untuk pengiriman berbasis misil yang ditentukan oleh kapasitas angkut misil. Peluru kendali balistik Rusia SS-18 memiliki daya angkut sebesar 7.200 &nbsp;kg, sehingga daya ledak maksimum mencapai 37,4 Mt. Fakta menyebutkan daya ledak [[SS-18]] mod 1 dengan satu hulu ledak mencapai 24 Mt. [http://warfare.ru/?linkid=1702&catid=265]

Where this data is not available, as in a number of cases, precise yields have been in dispute, especially when they are tied to questions of politics. The weapons used in the [[atomic bombings of Hiroshima and Nagasaki]], for example, were highly individual and very idiosyncratic designs, and gauging their yield retrospectively has been quite difficult. The Hiroshima bomb, "[[Little Boy]]", is estimated to have been between 12 and 18 kt (a 20% margin of error), while the Nagasaki bomb, "[[Fat Man]]", is estimated to be between 18 and 23 kt (a 10% margin of error). Such apparently small changes in values can be important when trying to use the data from these bombings as reflective of how other bombs would behave in combat, and also result in differing assessments of how many "Hiroshima bombs" other weapons are equivalent to (for example, the [[Ivy Mike]] hydrogen bomb was equivalent to either 867 or 578 Hiroshima weapons — a rhetorically quite substantial difference — depending on whether one uses the high or low figure for the calculation). Other disputed yields have included the massive [[Tsar Bomba]], whose yield was claimed between being "only" 50 Mt or at a maximum of 57 Mt by differing political figures, either as a way for hyping the power of the bomb or as an attempt to undercut it.

Nuclear testing yields, as in the Tsar Bomba example, can also be used as a way of reflecting upon technical expertise, and claiming higher yields or accusations of lower yields can be used as a way of promoting or disparaging the technical abilities of a nuclear program. When [[India]] claimed to have successfully detonated a hydrogen bomb in their 1998 [[Operation Shakti]] tests, many Western observers relied on analysis of [[seismograph]]ic data to determine whether the Indian tests reflected a successful hydrogen bomb detonation. Some have alleged that India's reported yields have been higher than their actual test yields, a move which would apparently be for political purposes (to claim more nuclear ability than their rival [[Pakistan]], for example, or to demonstrate their military might to other potential rivals such as nearby [[China]]) if true.--><!--
