B-2「幽靈」(Spirit)是目前世界上唯一的隱形戰略轟炸機,由麻省理工學院和諾斯羅普•格魯門公司一起為美國空軍研製生產。1997年首批6架B-2型轟炸機正式服役,至今只生產21架。每架B-2造價為二十二億美元。以重量計,B-2比黃金還要貴兩至三倍。 1999年,在北約對塞爾維亞的軍事行動中,美軍多架B-2轟炸機由美國直飛到塞國,期間共投下600多枚聯合直接攻擊彈藥,是空戰中隱匿性與準確性的一大革命。在2003年的演習中,一架B-2轟炸機一次投下80枚500磅(230公斤)的聯合直接攻擊彈藥,顯示出先進的「精確飽和攻擊」能力。
B-2是美國20世紀80年代提出的八大新技術軍機計畫之一。這八大軍機是:A-12(ATA)先進戰術攻擊機,B-2隱形戰略轟炸機,C-17(C-X)戰略戰術運輸機,E-8(JTIDS)空中聯合指揮系統,F-22(ATF)先進戰術戰鬥機,RAH-66(ATH,後更名LHX)隱形武裝直升機,V-22(JVX)傾轉旋翼飛機和海軍先進戰鬥機(NATF)計畫。其中的多數專案雖然完成了樣機的研製,但在冷戰結束後被大幅減少採購量甚至取消,ATA和NATF合併成為JSF項目。

號稱世界上“最昂貴的飛機”的B—2隱形轟炸機的價格驚人,每架高達22億美元
,幾乎是一艘小型艦艇的價格。
