Was Baron Vladimir Harkonnen the only person in the Dune series with a flying suit?

Question

Baron Harkonnen was so overweight that he requires anti-gravity devices known as suspensors to support his weight.

Did anybody else have suspensors to help them float or fly?

Such technology would have helped people out in the deserts to evade sand worms. It would also have helped the Harkonnen soldiers when the Fremen attacked. Looks like the Harkonnen family did not equip their own soldiers with such useful technology.

If the Baron's nephew, Feyd Rautha, had floating technology, he might have fared better in his duel against Paul Atreides.

Despite the practical uses of personal suspensors for combat and survival, I don't recall seeing the technology used by anyone else.

I have not read the Dune series in decades, so I can't recall if anybody else had a flying suit. Please provide answers based more on the books than the movie or the TV series.

Answer 1

In the original Dune, we see the Sardaukar using them instead of rappelling gear within the confines of the Shield Wall.

A rain of blue uniforms came over the cliff wall in front of him, falling in low-suspensor slowness. In the flashing instant, Hawat had time to see that they were Sardaukar, hard faces set in battle frenzy, that they were unshielded and each carried a knife in one hand, a stunner in the other.

Jessica posits that because they're based on the same tech as shields, that they may attract worms in the same way and hence be next to useless in the desert.

If only we had suspensors, Jessica thought. It’d be such a simple matter to jump down there. But perhaps suspensors are another thing to avoid in the open desert. Maybe they attract the worms the way a shield does.

A quick glance at the glossary shows her to be right.

SUSPENSOR: secondary (low-drain) phase of a Holtzman field generator. It nullifies gravity within certain limits prescribed by relative mass and energy consumption.
