Page "Operation Rolling Thunder" Paragraph 16

The majority of strikes during Rolling Thunder were launched from four Air Bases in Thailand: Korat, Takhli, Udon Thani, and Ubon.

The aircraft would refuel from aerial tankers over Laos before flying on to their targets in the DRV.

After attacking their targets ( usually by dive-bombing ) the strike forces would either fly directly back to Thailand or exit over the relatively safe waters of the Gulf of Tonkin.

It was quickly decided that, in order to limit airspace conflicts between Air Force and Naval strike forces, North Vietnam was divided into six target regions called " Route Packages ", each of which was assigned to either the Air Force or Navy and into which the other was forbidden to intrude.
