W9 (核砲彈)

W9 280mm火砲發射的原子彈
W9核砲彈在結果-節孔行動期間進行試驗,1953年5月25日,在內華達試驗場進行,爆炸當量為15千噸,約等於在第二次世界大戰期間在廣島投下的小男孩

W9是美國核火砲的其中一種砲彈,它由280mm特製榴彈炮發射。在1952年開始生產,在1957年全數退役,由W19所替代。

資料

W9直徑為11英吋(280 mm),54.8英吋(1,390 mm)長,重850磅(390 kg)。爆炸當量為15千噸(63 TJ)。

W9是槍式核分裂武器,使用約50kg(110磅)的高濃縮鈾,裝在一個環形中組件和一個「子彈」中,通過常規炸彈爆炸將「子彈」射向環形組件中以達到臨界質量和引爆武器。[來源請求]

W9的模組在1957年退役,並被裝在爆炸當量較低的T4-核子爆破武器英语T-4 Atomic Demolition Munition。T4-核子爆破武器是第一批(半)便攜式核武器。

試驗

W9是第二個已知被引爆的槍式核武器,第一個是第二次世界大戰中使用的小男孩。

W9曾被發射一次作試驗,由被稱為"原子安妮"的M65原子炮發射,是結果-節孔行動的一部分,代號為Grable,於1953年5月25日,在內華達試驗場進行,預期爆炸當量為15千噸。

隨後,W33也在其研發過程中進行了兩次核試驗(但不是從火砲發射)。這四次爆炸的武器都是槍式核分裂武器
