Which designation is the multi-mode missile that combines laser with GPS/INS?

• A. AGM-179A
• B. AGM-114P-4A
• C. GBU-53
• D. AGM-114N4

Answer: (A)

The ability to use a laser designation in terminal guidance while also navigating with GPS/INS lets a missile strike precisely in any weather and against moving targets, choosing the most reliable cue available. The AGM-179A Joint Air-to-Ground Missile is designed around that exact capability: a multi-mode seeker and guidance system that can use semi-active laser guidance when a laser designator is available and still rely on GPS/INS for midcourse navigation and all-weather accuracy. This combination provides flexibility across a wide range of targets and platforms, reducing reliance on a single cue and enabling effective strikes even if laser illumination isn’t continuous. It’s also built as a common, upgradeable platform intended to replace multiple older missiles, which reinforces why this designation is the best fit for a missile that combines laser guidance with GPS/INS. The other options either refer to different families with different guidance architectures (for example, a bomb rather than a missile) or rely on single-mode or alternative guidance schemes that don’t fuse laser designation with GPS/INS in the same integrated way.
