Ah! But which model of the B-52? Perhaps that would be a better question . . .
I'm about 90% sure it's a "G", not an "H"; it's definitely not a "D" because it's got the short vertical stabilizer, but it does have the older J-57 engines (the "H" model has more efficient and powerful TF-33 low bypass-ratio turbofans). I also notice it carries second-generation AGM-86 cruise missles; that, and the old "lizard" camoflage scheme place the picture at around 1990.
