  • LeiShi-6
  • Thunder Stone

The LS-6 guided bomb family is a Chinese satellite-aided inertially guided glide-bomb kit from the Luoyang Optoelectro Technology Development Center. Public references describe 50 kg, 100 kg, 250 kg, and 500 kg variants, GPS/INS guidance, and compact derivatives intended for internal carriage on stealth fighters such as the Chengdu J-20.

Smithsonian sources describe the HVAR as an effective Navy weapon that remained operational until 1955, while the Zuni entered service around 1958 with folding fins and continued in use into the 1980s. AV-8B inventory documentation still lists 5-inch rockets among the Harrier's air-to-ground stores.
