Which GBU's guidance unit comprises two sections located behind the warhead and ahead of the fins?

The main idea is how the guidance unit is built and mounted inside the bomb. The GBU-39 LCD is designed with a two-piece guidance unit that is split along the body so that one section sits behind the warhead and the other sits ahead of the fins. This two-section arrangement fits the compact 250-pound airframe and keeps the guidance electronics and actuators positioned between the warhead and the tail, without interfering with the warhead or the fins. The larger JDAMs (GBU-31 and GBU-38) use different, typically single-assembly guidance layouts, and the GBU-54 follows a different configuration as well. So the described two-section layout is characteristic of the GBU-39.
