Which munition weighs 1000 pounds and is laser-guided?

• A. MK-83
• B. GBU-16
• C. GBU-32
• D. GBU-12

Answer: (B)

The key idea is matching weight with how the weapon is guided. A 1000-pound bomb that is guided by a laser is the GBU-16, a Paveway II variant that puts a laser guidance kit on a 1000-lb bomb (the Mk-83 family). It uses a semi-active laser seeker to home onto energy reflected from a laser designator, allowing the aircraft or JTAC to illuminate the target and the bomb to track to it.

The other options don’t fit both parts simultaneously: the 500-pound laser-guided bomb is the GBU-12, the 1000-pound GPS-guided bomb is the GBU-32, and the Mk-83 by itself is an unguided 1000-pound bomb unless a guidance kit is added.
