Key Facts about AIM-174B:
| Feature | Details |
|---|---|
| Origin | United States |
| Type | Long-range air-to-air missile |
| Platform | Initially launched from F/A-18E/F Super Hornets (Navy) |
| Based on | RIM-174 SM-6 Standard ERAM (Extended Range Active Missile) |
| Range | Estimated over 200 miles (320 km) (likely exceeds AIM-120D) |
| Guidance | Active radar homing, inertial navigation |
| Warhead | Blast fragmentation |
| Speed | Likely Mach 3+ (similar to SM-6) |
| Role | Intercept high-value targets (bombers, AWACS, cruise missiles) at long range |
Background:
-
The AIM-174B is essentially a repackaged naval SM-6 missile, adapted for air launch, giving fighters a capability to engage targets far beyond the range of standard AIM-120 AMRAAMs.
-
First revealed in 2023 when a Super Hornet was seen carrying it in tests.
-
Likely intended for special scenarios, such as:
-
Denying access to airborne command and surveillance platforms
-
Extending reach over the Pacific in potential conflicts (e.g., China)
-
Comparison to Other Missiles:
| Missile | Estimated Max Range | Speed | Guidance |
|---|---|---|---|
| AIM-120D | ~160 km (100 mi) | Mach 4 | Active radar |
| AIM-260 JATM (future) | >200 km | Mach 4+ | Active radar |
| AIM-174B | >320 km | Mach 3+ | Active radar |
| R-37M (Russia) | ~300–400 km | Mach 5–6 | Active radar |
Challenges:
-
Size and weight: The SM-6 is a large missile (over 6 meters), so only large fighter aircraft like the Super Hornet can carry it.
-
Integration: Requires specialized pylons and software updates.
-
Likely not suitable for F-35 or F-22 due to internal bay limitations.
