Which missile features forward wings and a cryogenic engine in the seeker?

• A. AIM-9X
• B. AIM-7 Sparrow
• C. AIM-120 AMRAAM
• D. AIM-84

Answer: (A)

The feature set points to an infrared-imaging seeker that uses a cryogenic cooler and is paired with small forward fins on the nose. In modern IR-guided missiles, cooling the infrared detector with a cryogenic system dramatically improves sensitivity and allows the seeker to pick up heat signatures against hot backgrounds, extending effective range and lock-on performance. The AIM-9X incorporates this cryogenically cooled infrared seeker, and its design includes forward-facing fins near the nose to stabilize the missile during high-angle maneuvers and ensure accurate guidance when the seeker is tracking a heat source. The other missiles here rely on radar guidance or non-cryogenically cooled IR seekers, so they do not feature a cryogenic engine in the seeker or the distinctive forward-wing arrangement seen on the AIM-9X.
