The u.s. air force in 1967 instructed the company to Rockwell International, respectively, its Missile Systems Divisions, the development of the sequences-guided bombs, which would have incurred a modification of the existing load-edgy "iron" bombs Mk.84 and M118E1.
The result was a set composed of gear parts with the television camera and guidance system, vířiči on the hull of the cougar, and four tail surfaces with kormidly to control the flight of the bombs to the target. The image of the TV camera pumas was screened on a screen of the weapon operator. When was the "contrast" of the target compared to its background is large enough, has locked the guidance system of bombs on the target. Then after the release had on the object to guide autonomously. According to the data of the manufacturer it was a gun "shoot and forget", in practice, however, these pumas claims of its proponents, confirmed rarely. Modifier kit in the case of the GBU-9/B was of type KMU-390/B, the basis of conversion then became the puma M118E1. Compared to laser-guided munitions was this technology more expensive. Although it didn't need an aeroplane for the irradiation of targets with laser as in the pum series Paveway I, however, the accuracy of pum HOBOS was compared to the laser method of guiding the lower. Unlike GBU-8/B were not the GBU-9/B operationally deployed in Vietnam war.
Despite the contradictory results of the pum GBU-8/B in Vietnam, the development of this concept continued further, thereby incurring the cougar series GBU-15/B.

Dimensions: - length: 3,71 m - body diameter: 0,635 m - the span of the tail surfaces: 1,32 m
