We present unambiguous evidence for a parsec scale wind in the broad-line radio galaxy 3C 382, the first radio-loud active galactic nucleus, with R _L= log₁₀(f_5 GHz_/f4400_)>1, whereby an outflow has been measured with X-ray grating spectroscopy. A 118 ks Chandra grating (HETG) observation of 3C 382 has revealed the presence of several high ionization absorption lines in the soft X-ray band, from Fe, Ne, Mg, and Si. The absorption lines are blueshifted with respect to the systemic velocity of 3C 382 by -840 ± 60 km/s and are resolved by Chandra with a velocity width of σ = 340±70 km/s. The outflow appears to originate from a single zone of gas of column density N_H= 1.3x10²¹/cm2 and ionization parameter log(ξ/erg cm/s) = 2.45. From the above measurements we calculate that the outflow is observed on parsec scales, within the likely range from 10to1000 pc, i.e., consistent with an origin in the narrow-line region.
