Which variant of the AGM-158 is the JASSM-ER?

• A. AGM-158A
• B. AGM-158B
• C. AGM-158C
• D. AGM-158D

Answer: (B)

JASSM-ER is the extended-range version of the Joint Air-to-Surface Standoff Missile. In practice, the extended-range variant is the one designated as AGM-158B. The original JASSM, with the shorter range, is designated AGM-158A, while the other designations aren’t used for the ER version in standard inventories. The ER version achieves its longer reach through improved propulsion and aerodynamic refinements, allowing the aircraft to launch farther from the target while maintaining accuracy and survivability.
