The GBU-39 is an American precision-guided air-delivered bomb in the 250-pound weight class. It has a glide-wing design, giving it a range of 110 km from aircraft release point.

This thread 🧵 provides a breakdown of the munition's key components:

Nosecone: Located at the front of the munition, the GBU-39's nosecone is made from hardened steel—enabling the munition to penetrate concrete while remaining largely intact after the explosives detonate due to its heavy, metal construction

Warhead: Weighing 206 pounds, this is the portion of the munition carrying the explosive payload. GBU-39/B warheads use 37 pounds of high explosive. The complete warhead rarely survives intact unless the munition fails to function (does not detonate)

Wings: A folding assembly attached above the warhead section of the munition, creating a distinctive V-shape when deployed. These wings are often recovered after impact, as they can be sheared off as the bomb penetrates a structure before detonating

Fuzewell: Located at the base of the warhead, the fuzewell holds the munition’s fuze. When the fuze functions and the warhead detonates, the fuzewell is often ejected from the bomb’s body, meaning it can often be found intact nearby

Tail Actuation Section: Uses GPS and inertial guidance commands to control four hinged tail-fins, adjusting the munition's trajectory. It is located at the furthest point from the explosives, meaning it often survives the munition functioning
