The GBU‑16 Paveway II is a United States laser‑guided bomb (LGB) that combines a 500 lb (227 kg) Mk 82 general‑purpose bomb with a semi‑active laser (SAL) seeker and control fins to provide precision‑guided strike capability. It is part of the Paveway II family of weapons, which were developed to retrofit existing unguided "dumb" bombs with laser guidance using relatively simple add‑on kits.
Development and Service History
- The Paveway concept originated in the early 1960s, and the Paveway II series entered production in the mid‑1970s.
- The GBU‑16 designation follows the U.S. Department of Defense nomenclature for guided bombs, where “GBU” stands for “Guided Bomb Unit.”
- The weapon has been operated by the United States Air Force, Navy, Marine Corps, and Coast Guard, as well as by a number of allied nations that have purchased U.S. precision‑munitions.
- It saw extensive combat use in the Vietnam War, the Gulf War (Operation Desert Storm), the Kosovo campaign, the Iraq War, and more recent operations in Afghanistan and the Middle East.
Design and Components
| Component | Description |
|---|---|
| Warhead | Standard Mk 82 general‑purpose bomb, 500 lb (227 kg) high‑explosive warhead. |
| Guidance Kit | Semi‑active laser seeker (produced originally by Texas Instruments, later by Raytheon) mounted in the nose. |
| Control Surfaces | Four aerodynamic control fins, two fixed and two movable, enabling course corrections during descent. |
| Fuzing | Typically equipped with an impact or proximity fuze selectable by the delivering aircraft. |
| Range | Dependent on release altitude and speed; typical glide range is 8–15 km (5–9 mi) when released from high altitude. |
| Compatibility | Integrated with aircraft fire‑control systems via the MIL‑STD‑1760 interface; deployable from a wide range of fighter, attack, and bomber platforms (e.g., F‑15E, F‑16, F/A‑18, A‑10, AV‑8B, B‑1, B‑52). |
Operational Use
- The delivering aircraft illuminates the target with a laser designator, either on‑board or from a separate platform (e.g., ground‑based or airborne).
- The GBU‑16’s seeker detects the reflected laser energy and autonomously steers the bomb toward the designated point, correcting for wind, drift, and aircraft motion.
- Accuracy is generally reported as a circular error probable (CEP) of 3–5 m under optimal conditions.
Variants and Related Systems
- The Paveway II series includes the GBU‑10 (2000 lb) and GBU‑12 (500 lb with a different warhead configuration).
- Subsequent generations, such as Paveway III, incorporate advanced imaging infrared (IIR) seekers and extended‑range glide kits, but the GBU‑16 remains in service due to its proven reliability and lower cost.
Current Status
- While newer precision‑guided munitions are being fielded, the GBU‑16 Paveway II continues to be stocked and employed by several services, often in coordination with laser‑designator assets that remain widely available.
